Abstract

Microplastics (MPs) present in the environment are pervasive and tenacious as emerging pollutant concerns due to which global environment, flora, fauna, and aquatic bodies are now at an alarming stage. This is due to the result of anthropogenic activities and the unsuitable disposal, and unplanned segregation of plastics by humans. MPs are now additionally precarious because they enter into a higher level of organisms through a trophic level and biological magnification. This makes MPs an obscure risk to human health. According to certain research, MPs have a negative impact on feeding behaviour and obstruct digestive tracts in aquatic species, leading to sluggish growth. It also affects their respiratory, digestive, circulatory, and reproductive systems. Raman microspectroscopy was used to find MPs in the human placenta. The present review articles explain the glitches faced by microplastics to the environment along with animals, classifications, their mechanisms of entry, accumulation biological effects and mitigation process. In-depth study regarding MPs entry, accumulation and effects needs further research on the interactions with MPs which would provide an understanding of its impacts on the organisms due to its capability to sustain in the ecosystems for a long period. It has become crucial to propose the proper regulations and their implementation to reduce the generation and the occurrence of MPs in the environment.

Graphical Abstract

与微塑料相关的生物影响、生态毒性和健康风险综述
环境中存在的微塑料(MPs)是一种普遍而顽强的新兴污染物,由于全球环境,动植物和水生生物现在处于一个令人担忧的阶段。这是由于人为活动和不适当的处置,以及人类对塑料的无计划分离的结果。MPs现在更加不稳定,因为它们通过营养水平和生物放大进入更高层次的生物体。这使得国会议员对人类健康构成了一个隐晦的威胁。根据某些研究,MPs对水生物种的摄食行为有负面影响,并阻塞消化道,导致生长缓慢。它还会影响他们的呼吸、消化、循环和生殖系统。采用拉曼显微光谱法检测人胎盘中的MPs。本文综述了微塑料对环境和动物的危害、分类、进入机制、积累、生物效应和减缓过程。对MPs的进入、积累和影响的深入研究需要进一步研究与MPs的相互作用,这将有助于了解其在生态系统中长期维持的能力对生物体的影响。提出适当的法规及其实施以减少环境中MPs的产生和发生已变得至关重要。图形抽象

期刊介绍: Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
