The acorn is the nut of oak trees (genera Quercus and Lithocarpus) that can be found in the Northern Hemisphere. They are a valuable source of food for many animals (birds, rats, squirrels, pigs), but can pose health risks when consumed in large quantities. This nut contains gallotannin. When ingested, gallotannin is broken down into gallic acid and tannic acid. Tannic acid is toxic and can cause ulcers in the mouth, esophagus, and intestines, and damage the liver and kidneys. Animals that consume acorns as part of their diets (wild boars, deer, bears, birds, and squirrels) have some defense mechanisms against this toxin, such as waiting to consume them until enough groundwater has percolated through the acorns to leach the tannins or buffering the acorns with other foods. Some animals metabolize tannins better than others. Acorns can be particularly toxic to cattle, horses, and dogs, and fatal to all species when consumed in large quantities due to kidney failure. Animals with acorn poisoning may begin showing symptoms within hours or even several days after eating acorns. Symptoms include vomiting, diarrhea, cramping, abdominal tenderness, depression, rapid weight loss, loss of appetite, tiredness, and dehydration. There is no specific treatment for acorn poisoning, with prevention being key. Limiting access to fields with many oak trees to domestic animals during the fall is one measure. Diagnosis is based on clinical findings, necropsy, history, and histopathologic examination of the kidneys. Due to climate change, the weather has become increasingly dry throughout the year and forest fires are common, meaning that during autumn, often the only food available in some regions is acorns, leading to a silent killing of animals due to lack of resources. It is important that farmers and veterinarians are aware so that they can offer faster and more effective treatment. Full article

Modern farming is heavily dependent on the frequent application of pesticides that are known to disturb plant, animal, and microbial biodiversity (as well as accumulate in the environment and influence human health). Plant parasitic nematodes are some of the most damaging pathogens to food crops, impacting crop yield twice as much as phytophagous insects. To combat these pests, large amounts of pesticides are added to agricultural soils and eventually leach out to adjacent environments, accumulate in food and feed, and become very toxic. Volatiles produced by plants and microbes have been increasingly analysed for their anti-nematodal activities since they can present very active chemical structures suitable for developing novel biopesticides. The present study reviews the benefits of some of the most active compounds found in the literature in comparison to the most widely used commercial nematicides. By resorting to data retrieved from freely available online databases on their experimental properties, and given the use of certified software for the prediction of their environmental, toxicological, and ecotoxicological impacts, namely the US EPA Estimation Program Interface (EPI) and the Toxicity Estimation Software Tool (TEST), the advantages and disadvantages of using volatiles in the development of bionematicides are discussed. Ultimately, shifting to a more sustainable usage of pesticides and to farming practices that favor biodiversity can be beneficial to crop production. Full article

This study specifically validates the migration patterns of lead ions under sodium ion stress in soil and concludes that a high concentration of sodium ions, when coexisting with lead ions, diminishes the migration rate of lead ions, consequently reducing the removal efficiency of lead ions. 1. Introduction: Treatment of lead-contaminated soil has become a prominent research concern, with electrochemical treatment (ECT) technology demonstrating significant potential in this regard. ECT not only overcomes the drawbacks of traditional technology of soil remediation, such as long remediation periods, low efficiency, and high costs, but also enables in situ remediation. However, the influence of varying concentrations of non-contaminant ions on the removal efficiency of heavy metal ions during electrochemical treatment remediation of different naturally polluted soils remains unclear. Therefore, investigating the impact of sodium ion stress on the migration of lead ions is essential. 2. Methods: This study applies a DC power supply connected to an experimental device. The device is made of plexiglass and consists of three compartments: one soil compartment and two electrolytic compartments. A multimeter is installed with a wire between the DC power and the soil reaction device for monitoring the current. 3. Results: This study indicates a significant influence of the presence of sodium ions on the migration of lead ions during ECT. A high concentration of sodium ions induces ion competition in the soil, hindering the migration of lead ions and causing a decrease in their migration rate. Additionally, the competitive interaction between sodium ions and lead ions has a pronounced effect on the efficiency of ECT, leading to a reduction in the removal efficiency of lead ions. 4. Conclusion: These results emphasize the importance of considering sodium ion stress in the electrochemical remediation of lead-contaminated soil and provide valuable insights for optimizing electrochemical remediation strategies.

Early studies have documented that PM2.5 can not only induce cardiac tissue toxicity, but can adversely affect the performance of the myocardium and deteriorate its tolerance to withstand ischemia-reperfusion (IR) injury. The primary factor that contributes to the adverse impacts of PM2.5 exposure on the heart is subcellular changes, with particular emphasis on mitochondrial dysfunction, inflammation, oxidative stress, and deterioration of pro-survival signaling pathways. Despite the ongoing efforts to uncover the mechanistic changes induced in the heart by PM2.5 exposure, no studies have presented strategies for mitigating PM2.5-induced cardiotoxicity or enhancing the tolerance of the myocardium to withstand IR injury. Considering the potential of hydrogen sulfide, a gasotransmitter known to protect the heart from pathologies linked to oxidative stress and mitochondrial dysfunction, we explored the efficacy of H2S in attenuating PM2.5-associated increased IR injury. Female Wistar rats were exposed to 250 μg/m3 of PM2.5 for 3 h daily for 21 days, after which the hearts were isolated and mounted on an isolated rat heart apparatus. H2S was administered directly to the PM2.5-exposed hearts, after which the hearts were subjected to 30 min of ischemia and 60 min of reperfusion to induce IR injury. Our results revealed that the ability of the PM2.5-exposed myocardium to withstand IR injury had considerably improved. The pivotal mechanism driving these beneficial changes was the preservation of mitochondrial function (improved bioenergetics, respiration) along with quality control mechanisms. The improvement in mitochondrial function was also reflected in terms of reduced oxidative stress and activation of pro-survival signaling pathways. Based on these findings, we concluded that hydrogen sulfide holds promise as a potential therapeutic agent for enhancing the myocardium’s resilience to additional stressors in the form of IR injury.

Kodo millet, a staple food in North India, is frequently consumed, but its consumption can lead to intoxication and poisoning. Kodo millet is a rich source of nutrition, with anti-oxidant and medicinal properties, and is typically cultivated in dry and semi-arid regions. It is often infected by fungal species rather than bacterial and virus pathogens, causing economic crop loss and adversely affecting grain and fodder yield. Ergot, a parasitic fungal endophyte found in Kodo millet ear heads, can cause poisoning when consumed. Moreover, Kodo millet grains are frequently infested with Aspergillus tamarii Kita, which produces a significant amount of the mycotoxin cyclopiazonic acid (CPA). Cyclopiazonic acid (CPA) is a neurotoxin produced by certain A. flavus and Aspergillus oryzae strains, which produce aflatoxins. Mycotoxicosis outbreaks in humans are not well characterized, and the direct correlation between mycotoxin consumption and toxic effects In Vivo is not well established. CPA, a specific inhibitor of sarcoplasmic reticulum Ca2+-ATPase, can adversely affect broiler chicken health, as demonstrated by toxicological evaluation of aflatoxins and CPA alone or in combination. Most toxins have reported acute and chronic effects in prokaryotic and eukaryotic systems, including humans, despite thefact that their specific modes of action are unclear. This review explores fungal pathogens, the toxicity of CPA to animals and humans, both by itself and in combination with other mycotoxins, as well as biocontrol strategies and storage methods for better utilization of Kodo grains post harvest.

Global consumption has led to an increased and persistent plastic pollution in the aquatic environments. Due to their small size, plastic particles are omnipresent, affecting aquatic biota. Polystyrene is a synthetic polymer and one of the most widely used plastics. Its accumulation in the environment endangers the health of aquatic organisms. This study aims to investigate the acute (7 days) and chronic (75 days) toxicity of spherical polystyrene particles (20, 200, 430 µm) on Cyprinus carpio fish using OECD methodology. No mortality or behavioral changes were recorded after acute or chronic tests conducted on 1, 10, 100 mg/L polystyrene particles. Polystyrene showed bioavailability mainly through ingestion with food, causing weight loss in fish. Fish lots exposed to the polystyrene mix (particle sizes of 20, 200, 430 µm and 1.2 mg PS/L total concentration) showed changes in physiological indices but without major significance compared to control lots. After 75 days of chronic exposure of fish to a mix of polystyrene particles, organs were collected for sub-lethal effect investigation. Polystyrene was found to cause oxidative stress in fish organs. A very significant increase in the activity of the enzymes catalase and glutathione reductase, correlated with lipid peroxidation in gills, were observed. In the liver, catalase and glutathione S transferase activity increased, but there were no lipid peroxidation effects. Also, alanine transferase and aspartate transferase activity showed significant changes. Regarding the vitellogenesis initiated in the liver, vitellogenin activity increased by 40%. EROD activity saw a 20% increase compared to control fish, indicating stress enzyme expression. Instead, acetylcholinesterase showed significant inhibition (>80%) in the brain and muscle. The protein profile showed new stress protein expression compared to the control in the gills and liver. Based on the results of our study, the introduction of new regulations monitoring the accumulation of microplastics in surface water is an urgent matter. Full article

Wastewater management is a complex issue that requires attention due to the presence of harmful pollutants, toxic particles, and emerging contaminants that originate from industrial activities. These pollutants can contaminate the soil and surface water, and infiltrate groundwater, posing health risks to humans and animals alike. The emerging contaminants in wastewater, such as pharmaceuticals, personal care products, pesticides, and flame retardants, are primarily synthetic organic compounds that pose serious risks to human health and biota. The demand for freshwater is increasing, which necessitates significant investments in capital and energy for water treatment plants. This review article explores the innovative use of plants in wastewater treatment, specifically through bioaccumulation. Various phytoremediation techniques, such as phytovolatilization, phytoextraction, phytofiltration, rhizofiltration, phytodegradation, phytostabilization, and phytoassimilation, are explored as sustainable alternatives. Aquatic plants, such as water hyacinth, duckweed, and water lettuce, stand out for their exceptional phytoremediation capabilities. These plants can be used to remove pollutants from wastewater, making it safe for reuse or discharge into the environment. The use of plants in wastewater treatment is a cost-effective and eco-friendly approach that can help address the growing water scarcity problem. By using phytoremediation techniques, we can reduce the need for expensive and energy-intensive treatment methods, while also promoting the growth of green spaces in urban areas. This article underscores the potential of plant-based strategies in wastewater management, emphasizing their role in mitigating environmental contaminants and safeguarding public health. Full article

Organophosphate compounds are one of the leading causes of death due to poisoning worldwide due to their easy accessibility as insectides and pesticides. Ninety-five percent of pesticide poisonings occur in developing countries, especially in the Asia–Pacific region. Moreover, in countries like India, pesticides are one of the most commonly used suicidal poisons because of their easy accessibility. Agriculture being the country's main source of occupation, pesticides are easily accessible throughout India. Organophosphorus toxicity can commonly occur due to household pesticide use or due to occupational exposure. Though rare, accidental poisoning can occur in people working in the pesticide industry, farmers, and sometimes in the general population. Organophosphorus compounds are absorbed by all routes and cause fatality unless treated with the appropriate antidote. Suicidal poisoning will usually be by ingestion, whereas accidental poisoning will be either inhalational or dermal. Homicidal poisoning cases with the use of organophosphorus compounds have also been reported in the literature. People may become unknowing victims of these chemicals. The dermal absorption of these compounds is common, but it rarely results in fatality. Acute poisoning is common after oral, respiratory, or dermal exposure to low-volatility or high-volatility pesticides. We present an accidental fatal case of organophosphorus poisoning wherein the mode of entry was through dermal absorption. Full article

The levels of pharmaceuticals have been continuously increasing in aquatic ecosystems over the past decade due to their extensive use in human and veterinary medicine. Traditional water monitoring methods have been proven insufficient to capture pollution due to pharmaceuticals because of sensitivity limits, their inability to monitor every pollutant, and their failure to provide mechanistic insights into the actions of pollutants. To combat this, new approach methodologies (NAMs) are increasingly introduced as supplementary tools that can provide sensitive metrics for pollution assessment. In addition, NAMs can bridge the gap in ecotoxicological information regarding mixtures of pharmaceuticals, which are more commonly found in aquatic ecosystems versus pharmaceuticals existing alone. In this context, freshwater sentinel species, such as the water flea known as daphnids, were used to assess the acute effects of a typical pharmaceutical mixture on various physiological and molecular responses. In addition to mortality, phenotypic and molecular endpoints such as ingestion rate and enzyme activity were measured to determine the impact of a cocktail of commonly prescribed pharmaceuticals. Specifically, diclofenac, metformin, gabapentin, amoxicillin, trimethoprim, and erythromycin were mixed in equal amounts and tested at 0.1, 1, and 10 mg/L. Results showed differences in mortality, a decrease in feeding, and changes in enzyme activities, thus supporting a distinct pattern in the physiological responses of daphnids Full article

Terpenoids constitute one of the most widespread phytoconstituents, with complex chemical structures, a plurality of biological activities, and variable pharmacokinetic profiles. The emerging roles of terpenoids in drug design require an understanding of their ADME/T properties for structure modification and possible repurposing. This study evaluated the drug-likeness of phytotoxic terpenoids obtained from the Toxic Plants–Phytotoxins (TPPT) database via in silico prediction of their pharmacokinetic and toxicity profiles. The TPPT database, comprising 1586 phytotoxins, was filtered to 576 terpenoids. Using Swiss ADME, pkCSM, and ProTox II webserver tools, Lipinski’s properties and topological polar surface area (TPSA) were predicted for drug-likeness, alongside their pharmacokinetic profiles and toxicity on various organ endpoints. In total, 9.55% of the terpenoids obeyed Lipinski’s rule of five. None of the compounds inhibited hERG I, while 12.73% inhibited hERG II, implying that some were cardiotoxic. In addition, 25.45% of the compounds elicited AMES toxicity; 25.45% caused liver injury; and 32.73% caused skin sensitivity. Furthermore, 72.73% showed high Caco-2 permeability and 76.36% displayed good skin permeability, implying their suitability for transdermal drug delivery. P-glycoprotein was extruded by 29.09% of the compounds and inhibited by 34.45%; 47.27% of the compounds readily crossed the blood–brain barrier, 23.64% penetrated the central nervous system, 56.36% were sensitive to cytochrome p450 isoenzymes, 36.37% inhibited cytochrome p450 isoenzymes, 49.09% resulted in immunotoxicity, 1.82% were toxic to cells, 14.55% would cause cancer, and 21.82% showed high tolerated doses in humans. Most of them showed a high volume of distribution, were free-flowing in plasma, and demonstrated moderate bioavailability, while all had high intestinal absorption and 78.18% demonstrated good water solubility. This study identified marrubiin as a drug-like, non-toxic, and highly bioavailable terpenoid with strong potential for further optimization, and development. Full article

Silver (Ag) is extensively used in a broad spectrum of personal care products and industrial products. Ag was analysed in scalp hair from 120 children (6 to 9 years old; 70 females) born/residing in Alcalá de Henares (Spain), and in randomly collected topsoils from different urban parks (n = 97) across Alcalá. Ag was detected in all samples (LoDs in hair and topsoils in µg/g: 0.0036, 0.049), except in three hair samples. Levels of Ag were significantly higher in females (median and range, in µg/g): 0.1199 (0.0168–0.4906) vs. 0.08916 (0.0139–0.3841), and slightly lower compared to those reported in hair from children (6–10 years-old) living in Madrid [0.1107 (0.0139–0.4906) vs. 0.251 (0.132–491); all in µg/g]. These authors also reported the deposition of Ag in hair was higher in females. The Spanish capital, Madrid, is more polluted than Alcalá, which could explain our results. Thus, the levels of Ag in Alcalá’s topsoils [0.0680 (0.0492–4.0493)] were lower than those reported in other urban areas such as in Athens, Greece [0.260 (0.017–7.430); all in mg/kg]. Although the examination of the pollution index values (2.46; 0.65–53.55; data provided as mean and range) suggest some anthropogenic origin for the Ag found in the topsoils, the distribution of this contaminant was minimal and was only detected in 62 of the topsoil samples collected. Hazard quotients (HQs) for Ag were determined for ingestion and dermal contact; all values were lower than the safety thresholds for HQs (unity), suggesting a minimal risk for the population. Our results suggest that the monitored child population from Alcalá has a minimal exposure to Ag, as the geometric mean was lower than that reported in children living in Iglesias (0.095 vs. 0.13, 0–3 years-old) and much lower than that reported in children living in the polymetallic mining area in the Bolivian Altiplano (0.33, average 7.9 years-old; all in µg/g).

Coastal sediments are a powerful tool for analyzing pollution levels and reconstructing history. The Oualidia lagoon plays an essential role as it provides several ecosystem services, including aquaculture, fisheries, and coastal tourism, among others. Therefore, the conservation and protection of this natural system requires the continuous monitoring of its environmental quality. The present study evaluates the potential ecological risks of Cr, Cd, Pb, and As in coastal sediment cores collected from the Oualidia lagoon. These sediment cores were also dated using lead-210 to study the temporal variations in the studied metals. The potential ecological risk values of the metals show a moderate ecological risk to the lagoon since the 1950s, while the toxic units indicate low toxicity. The Adverse Effect Index (AEI) values indicate a probable effect on biota due to the concentrations of Cr, As, and Cd, mainly in the surface layers. This suggests that the development of human activities in the last two decades has contributed to increased heavy metal concentrations, leading to potential ecological risks to the lagoon. Activities such as agriculture can be potential sources of Cd. Excessive use of fertilizers and pesticides may contribute to the increase in this heavy metal in the lagoon. This finding highlights the need for the careful monitoring and remediation of Cd levels in this aquatic system, as Cd presents a high ecological risk value among the selected heavy metals.

Leishmaniasis, caused by the protozoan Leishmania spp. and transmitted by sandflies, affects 2 million people worldwide yearly and is recognized as a global problem by the WHO. Current treatments, including amphotericin B, Pentamidine, and Glucantime, show limited efficacy and serious side effects. Trypanothione reductase is a promising protein target for developing new promising drugs against Leishmaniasis. This study explores Schiff base compounds as potential alternatives to current treatments by inhibiting trypanothione reductase. Thirty-nine structures from the PubChem database were selected and analyzed using AutoDock Vina 1.1, an in silico molecular docking tool. Promising Schiff base candidates, indicated as compound 21 (3-Quinolinamine, N-(2-quinolinylmethylene)-, compound 24 (1,3-Bis[(E)-(2-Amino-4-Ethyl-5-Hydroxy-Phenyl)Methyleneamino]Urea, and compound 39 (Naphtaldehyde disulfide Schiff base), exhibited significant inhibitory binding affinity against trypanothione reductase, outperforming commercial inhibitors. Therefore, the present study proposes alternative Schiff base compounds for treating Leishmaniasis. Full article

The increasing global interest in herbs and spices necessitates a thorough examination of the chemical hazards associated with their consumption. The objective of this work was to provide an understanding of the current state and prevalence of chemical contaminants (toxins, heavy metals, and pesticide residues) in herbs and spices consumed in Europe, facilitating informed decision-making in public health and regulatory frameworks Through an extensive literature search, contamination levels of chemical hazards among different herbs and spices were evaluated. The European Rapid Alert System for Food and Feed (RASFF) has shown 1133 notifications for spices and herbs in the last 10 years (2013–2023). Focusing on the chemical hazards associated with the consumption of these products, mycotoxins (especially aflatoxins and ochratoxin A) and plant-derived compounds with potential health implications (e.g., pyrrolizidine alkaloids) were the most often notified. Nevertheless, besides these naturally occurring compounds, other deliberated added substances such as artificial unauthorized dyes (e.g., Sudan I, II, III, and IV) that can pose a human health risk have been identified. Finally, environmental contaminants could also be present in herbs and spices. Pesticide residues (e.g., chlorpyrifos, carbendazim, and bifenthrin) have been notified, and studies in terms of their persistence and adherence to regulatory limits and heavy metals were also investigated, focusing on cadmium, lead, and mercury due to the bioaccumulation abilities of plants. Other environmental contaminants, such as dioxins and dioxin-like polychlorinated biphenyls (dl-PCBs) and polycyclic aromatic hydrocarbons (PAHs), were considered for this study. In conclusion, this work contributed to identifying gaps and challenges in regulatory practices and to the dialog on the safety and quality of herbs and spices, offering a holistic perspective on toxins, heavy metals, and pesticide residues and fostering collaboration between all stakeholders to advance in public health protection in Europe.
