(Micro)Plastics Are Toxic Pollutants

Toxics, Journal Year: 2023, Volume and Issue: 11(11), P. 935 - 935

Published: Nov. 17, 2023

Plastics, including microplastics, have generally been regarded as harmful to organisms because of their physical characteristics. There has recently a call understand and regard them persistent, bioaccumulative, toxic. This review elaborates on the reasons that microplastics in particular should be considered “toxic pollutants”. view is supported by research demonstrating they contain toxic chemicals within structure also adsorb additional chemicals, polychlorinated biphenyls (PCBs), pesticides, metals, polycyclic aromatic hydrocarbons (PAHs), from environment. Furthermore, these can released into tissues animals consume responsible for effects observed biological processes such development, physiology, gene expression, behavior. Leachates, weathering, biofilm play important roles interactions between biota. Global policy efforts United Nations Environmental Assembly via international legally binding treaty address global plastic pollution consider designation plastics (e.g., microplastics) with associated hazardous pollutants.

In-situ detection of microplastics in the aquatic environment: A systematic literature review

The Science of The Total Environment, Journal Year: 2024, Volume and Issue: 934, P. 173111 - 173111

Published: May 12, 2024

Microplastics are ubiquitous in the aquatic environment and have emerged as a significant environmental issue due to their potential impacts on human health ecosystem. Current laboratory-based microplastic detection methods suffer from various drawbacks, including lack of standardisation, limited spatial temporal coverage, high costs, time-consuming procedures. Consequently, there is need for development in-situ techniques detect monitor microplastics effectively identify understand sources, pathways, behaviours. Herein, we adopt systematic literature review method assess application experimental field technologies designed monitoring microplastics, without sample preparation. Four scientific databases were searched March 2023, resulting 62 relevant studies. These studies classified into seven sensor categories working principles discussed. The classes include optical devices, digital holography, Raman spectroscopy, other hyperspectral imaging, remote sensing, methods. We also looked at how data these integrated with machine learning models develop classifiers capable accurately characterising physical chemical properties discriminating them particles. This concluded that environments feasible can be achieved accuracy, even though still early stages development. Nonetheless, further research needed enhance microplastics. includes exploring possibility combining developing robust machine-learning classifiers. Additionally, recommendation implementation reviewed effectiveness detecting limitations.

Abstract Prior to entering the water body, microplastics (MPs) are mostly collected at sewage treatment plant and biological unit is facility's central processing unit. This review aims present a comprehensive analysis of detrimental impacts MPs on it covers how harm effluent quality processes. The structure microbial communities altered by presence additive release, which reduces functional activity. Extracellular polymers, oxidative stress, enzyme activity explored as micro views harmful mechanism microorganisms, examining toxicity additives released caused microorganisms compounds that have been adsorbed in aqueous environment. article offers theoretical framework for thorough understanding potential problems posed plants suggests countermeasures mitigate those risks aquatic
