Large populations are exposed to fresh surface water and plastic packaged drinking water that are contaminated with particulate plastics around the world. In the review, particulate plastics are discussed in relation to the exposure of humans to particulate plastics and the potential risks of adverse health effects. About 4,000,000 particles may be ingested and internalized annually by human beings. Current studies indicate that environmental management of particulate plastics is still in its infancy in many developing countries, and that they have received limited research attention with regard to their potential release into drinking water. Currently, there are no standard protocols for testing these materials in environmental media, and testing methods for these materials are inconsistent. Considering that the risk assessment pathways for particulate plastics have not been validated, the current study emphasizes the need to strengthen the capacity of developing countries to monitor the environment and manage plastic waste in a circular manner. A holistic and a more comprehensive approach is recommended in the paper for evaluating particulate plastics in drinking water and other environmental matrices using quality-assured methods. At the continental level, they proposed an African framework that commits to a circular plastics program by considering: improvements in waste separation and collection, improvements in recycling rates and increasing demand for recycled products, increasing penetration of bioplastics, advocating for the manufacturing of cleaner packaging through product re-engineering, advocating for re-useable plastics
This paper characterizes the fungal and bacterial colonizers of 5 types of plastic films (High-Density Polyethylene, Low-Density Polyethylene, Polypropylene, Polystyrene, and Polyethylene Terephthalate) throughout a 242-day incubation in the south-eastern Mediterranean and relates them to the chemical changes observed on the surface of the samples via ATR-FTIR. Neither bacterial nor fungal community structures were related[…]
This paper provides insights into the sustainable alternatives that can replace conventional plastic mulches, such as biodegradable mulches made from natural fibers and biopolymers. The microscopic and FTIR analyses conducted during the study showed the degradation of the fibers from the mulches during the exposure time to a certain extent. The nonwoven mulches provide higher[…]
This paper investigates the degradation of biodegradable polybutylene adipate terephthalate/polylactic acid (PBAT/PLA) and traditional polyethylene (PE) plastic under two typical abiotic conditions: ultraviolet (UV) irradiation and mechanical abrasion (MA) for up to nine months. The quantitative analysis of the degradation products was carried out using membrane filtration and total organic carbon determination (MF-TOCD). The results[…]
This paper identifies technological innovation, policy formulation, advocacy and sensitization, and bioremediation as some of the approaches that are currently used for the mitigation of plastic pollution in Nigeria. This chapter also highlights the need to encourage, enhance, and disseminate scientific research on mitigating the harmful effects of plastic pollution in Nigeria. It concluded with[…]
This review provides insights into the sources of microplastics, the ecotoxicity of microplastics, and the impact microplastics have on aquatic and marine life, management, and bioremediation of microplastics. Policies and strategies adopted by the government to combat microplastic pollution are also discussed in this review. Microplastics tend to accumulate in many aquatic systems, contaminate them,[…]
