Abstract:

Plastic waste is a solid that is difficult to decompose but can turn into environmental microplastics. Microplastics are sizes between 0.1 μm–5 mm, highly prolific anthropogenic pollutants affecting terrestrial, freshwater, and marine ecosystems. The purpose of this study was to determine the ability of Babylonia spirata to accumulate and eliminate polystyrene microplastics. This experiment uses the nuclear applications technique. The experiment consists of two methods: manufacturing microplastics and biokinetics. The manufacture of microplastics labeled Zn-65 is based on the reaction of polys

Abstract Microplastic pollution has become an increasingly concerning environmental problem because of its adverse impact on aquatic ecosystem security. Microplastics in the aquatic environment are poisonous to aquatic life, and they can not only be consumed by aquatic life but also pass down the food chain, endangering human health in the process. To investigate the accumulation and transfer of three different functional microplastics, including polystyrene (PS), carboxylate-modified polystyrene (PS-COOH), and amine-modified polystyrene (PS-NH2), in the aquatic food chain between Chlorella py

Abstract:

The contamination of food by microplastics has garnered widespread attention, particularly concerning the health risks associated with small-sized microplastics. However, detecting these smaller microplastics in food poses challenges attributed to the complexity of food matrices and instrumental and method limitations. Here, we employed Raman imaging for visualization and identification of polystyrene particles synthesized in polymerization reactions, ranging from 400 to 2600 nm. We successfully developed a quantitative model of particle size and concentration for polystyrene, exhibiting excel

Abstract:

Plastics, primarily microplastics, are among the greatest pollutants in aquatic environments. Their removal and/or degradation in these environments are crucial to ensure an optimal future of these ecosystems. In this work, MnO2 particles were synthesized and characterized for the removal of polystyrene microplastics as a model. MnO2 catalyzes the peroxide reaction, resulting in the formation of oxygen bubbles that propel the pollutants to the surface, achieving removal efficiencies of up to 80%. To achieve this, hydrothermal synthesis was employed using various methods. Parameters such as MnO

This study aimed to assess the extent of microplastic contamination by analyzing microplastic trash collected from 25 spots along the Tamil Nadu coast, spanning a distance of 1076 kilometers. The results revealed that microplastic contamination was more prevalent during higher wave conditions compared to lower tides. Shorelines near riverbanks exhibited significantly higher quantities of microplastics than those affected by fisheries and tourist activities.

Abstract:

Microplastics (MPs) are currently global environmental pollutants, and their associated health risks cannot be ignored. However, research on MP toxicity in mammals is limited. We investigated the effects of polystyrene microplastic (PS-MP) particles on the lipid profile and oxidative stress markers of Wistar rats. Two forms of PS-MP-pristine polystyrene and Styrofoam microplastics-particles of diameter <5 mm were used in this study. Each form was separately incorporated into rat feed in varying proportions of 1, 5 and 10%. A total of seventy rats (thirty-five male and thirty-five female rat

The presence of microplastics in aquatic systems is mainly due to the anthropogenic activities such as domestic waste dumping. Undeniably, rivers either in urban or suburban areas are always a waste dumpling sites from the surrounding residences. Thus, the purpose of this study was to determine the relationship between microplastic abundance and different degree of urbanization across Kuching in Sarawak. Three sampling locations with different degrees of urbanisation had been studied across Kuching. A total of 137 pieces of microplastics were collected along the study and analysed using stereo

Plastic waste in marine waters will undergo a degradation process that breaks down large plastic pieces into smaller particles called microplastics. The abundance of microplastics, caused by their small size (<5mm) can be easily indirectly consumed by aquatic animals. Anadara granosa is one of the bivalves that is quite vulnerable to microplastic contamination because it has the nature of a filter feeder which means it can sift particles and organic matter around it. The purpose of this study was to determine the characteristics, abundance, and types of microplastic polymers in blood clams
