Special Issue Information

Dear Colleagues,

With the continuous development of industrial activities, an increasing number of pollutants are produced and discharged into the aquatic environment. The pollution in drinking water and wastewater, including conventional pollutants (e.g., fluoride ions, nitrate ions, pathogens, and heavy metals) and emerging contaminants (e.g., pharmaceuticals and personal care products, perfluorinated compounds, and microplastics), represent a major risk to the environment and health due to their wide distribution in water bodies and accumulation in nature. Nevertheless, conventional water treatment processes may no longer meet the requirements for the further improvement of water quality. The limited knowledge regarding the fate and degradation mechanism of emerging contaminants is another global challenge. Therefore, novel, robust, cost-effective, and environmentally friendly methods for water pollution control and treatment are necessary to supplement or replace the existing treatment processes and to address these challenges.

This Special Issue welcomes high-quality articles in the field of water and wastewater treatment, which utilize advanced approaches with a major focus on water pollution control. Fundamental and applied research papers covering multidisciplinary topics, as well as review papers with new perspectives will be considered. The development of advanced treatment technology, including physicochemical, membrane separation, advanced oxidation, and biological processes, and their combinations, which warrant further investigation in sustainable water treatment, is at the core of this Special Issue.

The scope of this Special Issue includes, but is not limited to, the following topics:

(i) Advanced detection methods of emerging contaminants;

(ii) Remediation technologies including, but not limited to, photocatalytic and bio-degradation, advanced oxidation, membrane separation, and other standalone and/or hybrid processes;

(iii) Molecular dynamics and simulations explaining the contaminant fate and degradation mechanism;

(iv) Costs and benefits analysis of pollutant removal processes and technologies;

(v) Reviews on the most effective practices.

Distribution Characteristics and Influencing Factors of Organochlorine Pesticides in Agricultural Soil from Xiamen City

by Ziqiang Gao, Yixian Chen, Qijin Qin, Rui Wang and Zhineng Dai

Int. J. Environ. Res. Public Health 2023, 20(3), 1916; https://doi.org/10.3390/ijerph20031916 - 20 Jan 2023

Abstract

The concentration and distribution of 15 organochlorine pesticides in the soil of Xiamen City were determined. Overall, among the 15 selected target pesticides, 14 organochlorine pesticides (OCPs) were detected (hexachlorobenzene was not). The range of detected pesticides was undetected−10.04 ng/g, the total detection rate was 35.2%, and the three pollutants with the highest detection rate in all samples were Heptachlor (66.7%), δ-Hexachlorocyclohexane (60.0%), and p, p′-Dichlorodiphenyldichloroethane (58.3%). The degree of pollution in descending order was Tong’an > Xiang’an > Jimei > Haicang. Linear regression analysis of soil properties and OCP concentration distribution revealed that OCPs were positively correlated with water content, dissolved organic carbon, and pH and negatively correlated with cation exchange capacity. The origin of OCPs was evaluated using the relationship between the parent compound and its metabolites, with possible new hexachlorocyclohexane and isomer (HCHs) input. By comparing the risk screening values of ΣHCHs and ΣDDTs in “Soil Environmental Quality Standards”, the concentrations in all soil samples were lower than the standard values, which indicated that the OCP residues in Xiamen were very low.

Experimental Research on the Treatment of Stormwater Contaminated by Disinfectants Using Recycled Materials—Hemp Fiber and Ceramzite

by Marina Valentukeviciene, Ieva Andriulaityte and Ramune Zurauskiene

Int. J. Environ. Res. Public Health 2022, 19(21), 14486; https://doi.org/10.3390/ijerph192114486 - 4 Nov 2022

Abstract

Pollution caused by the use of disinfectants in public spaces is a relatively new form of environmental contamination. During the COVID-19 pandemic of 2020–2021, early research showed a sevenfold increase in the use of disinfectants to clean outdoor spaces and a corresponding increase in environmental pollution. Typically, after entering stormwater systems, disinfectants are carried to surface waters (e.g., rivers, seas and lakes) where they react with various elements to form harmful compounds. In the absence of data, it is not possible to determine accurate levels of pollution according to the latest scientific information. Our enquiry demonstrates that stormwater pollution indicators (pH, conductivity, turbidity and color intensity) change depending on the amounts of disinfectants present. Laboratory tests were conducted using hemp fiber and ceramzite, in which filtered stormwater samples contaminated with different amounts of disinfectants showed decreases in the amounts of active chlorine from 2.93 ppm to 1.0 ppm. Changes in pH levels, conductivity, turbidity and color intensity were monitored before and after filtration; pH indicators changed slightly (from 7.81 to 7.85), turbidity changes varied in the range of 0.070–0.145 NTU and the highest value of color intensity (1.932 AV) was obtained when 50 mL of disinfectant was added to the investigated sample water. This article presents the results of our research into the impact of disinfectants on stormwater. Further investigation is needed in order to determine the impacts of chemical substances on our water ecosystem. Full article

The Effects of Wastewater Treatment Plant Failure on the Gulf of Gdansk (Southern Baltic Sea)

by Marta Jaskulak, Maksymilian Sotomski, Małgorzata Michalska, Roman Marks and Katarzyna Zorena

Abstract

In August 2019 and during August/September 2020, the main collection system of the Wastewater Treatment Plant (WWTP) in Warsaw, Poland, malfunctioned. During that system failure, over 4.8 million m³ of untreated wastewater was dropped directly into the Vistula River in just a few days. It is currently considered as one of the largest known failures of WWTP worldwide. In order to assess the environmental impact, water samples were collected from 2 spots at the Vistula river estuary (406 and 415 km from the discharge location, respectively), and 4 spots at the Gulf of Gdansk, situated on the southern shore of the Baltic Sea. The sampling was conducted before the wastewater wave reached the Vistula river’s mouth, followed by daily sampling during 21 days after the malfunction occurred. The study showed the decline in water quality at the Vistula river estuary and the Baltic shore waters as the wave of wastewater reached those points, despite being situated over 400 km downstream from the place of the accident. Those changes included the reduction in the dissolved oxygen content (by 0.69-fold at its peak), the increase in Total Organic Carbon (TOC) (by 1.28-fold at its peak), nitrate-nitrogen (N-NO₃) (by 1.68-fold at its peak), phosphorous (P) (by 2.41-fold at its peak), conductivity (by 16.8-fold at its peak), and Chemical Oxygen Demand (COD) (by 1.84-fold). In the samples from the Vistula river, the decline in water quality was seen as incidental and lasted 2–3 days. Subsequently, the levels of physical and chemical parameters returned to the levels from before the accident. However, the changes in the Gulf of Gdańsk lasted significantly longer, especially on the West side of the Vistula river, where, even after 21 days from the initial accident, some parameters remained altered.
