Special Issue Information

Dear Colleagues,

Currently, human activities lead to high input of microplastics into the environment, invading our life and vigorously interrupting our food chain, the process that should track our attention and directs our research efforts to study how this negatively affects our health and lifestyle. Microplastics (MPs) come from many sources including, but not limited to, plastic bags, water bottles, food packings, coatings , and paints (for example, coatings/paint-MPs pollution arise from external surfaces of buildings, ships, and boating activities), which are widely used in different applications. They usually consist of different polymers including polyesters, polystyrenes, polyurethanes, polyacrylates, and polyamides. They contribute to the release of microplastics (MPs)/nanoplastics (NPs) in marine and terrestrial environments. MPs not only act as a marine and terrestrial environment pollutant, but also could act as a vector for potentially toxic elements and biocides contamination. Recently, different research articles have reported MPs contamination in food and beverages. The serious problem is the transfer of MPs and any other adsorbed toxic pollutants to humans through the food chain. This clearly mentioned in a few articles that detect MPs contamination in human serum, umbilical cord, and stool. Briefly, any source causing an increase in MPs could affect our terrestrial, marine, and freshwater biota, which in turn could increase the implications for human health.

Highlights

  • Different sources of microplastics contamination.
  • Different methods of MPs extraction.
  • Fluorescence microscope and FTIR for MPs detection.
  • Microplastics’ prevalence in aquatic or terrestrial
  • Microplastics pollution in food and drinks.
  • Risk assessment of nanoplastics contamination on human cells.

Plastic products used in our daily life remain in the environment for a long time. Plastics decompose gradually into smaller fragments (<5 mm) known as microplastics. There are different sources of microplastics contamination, including plastic bags, masks, synthetic textiles, and various coatings. Microplastics’ smaller size enhances toxic pollutants’ adsorption, through which they are easily digested by small biota and finally accumulated along the food chain. Many studies are found concerning marine microplastic distribution and pollution; however, rarely do they address terrestrial contamination. The terrestrial species Eobania vermiculata, Rumina decollata, Porcellio, Armadillo, Lumbricus terrestris, and Scolopendra were evaluated as bioindicators for soil pollution by microplastics and some potentially toxic metallic elements. Microplastics were isolated with the help of caustic potash. The particles were characterized by infrared spectroscopy (FTIR); some associated potentially toxic metals were assessed in the filtrate by inductively coupled plasma spectrometry (ICP). The following polymers were present in all studied samples: copolyamide, nylon, high- and low-density polyethylene, polyamide, and polyester. In addition, the metallic elements antimony, iron, aluminum, selenium, and zinc were determined with different concentrations. Thus, terrestrial biota can serve as bioindicators for microplastic pollution of soil, which could act as a vector for potentially toxic elements. Full article
