Abstract

The global production of plastics has surged to 368 million tonnes annually, leading to significant plastic waste accumulation, projected to reach 12,000 Mt by 2050, impacting aquatic ecosystems. Fish, crucial for their protein and nutrients, are particularly vulnerable to microplastic (MP) ingestion. As a major aquaculture producer and fish consumer, India faces rising plastic pollution in freshwater, which disrupts fish health and growth, posing a significant threat to the sustainability and productivity of aquaculture systems and potential health risks. This study focuses on Mozambique tilapia (Oreochromis mossambicus), valued for its widespread aquaculture use, rapid growth, and nutritional benefits. Our research reveals significant MP contamination (69.23 %) in Mozambique tilapia, with over 80 % from the Ulhas River and 60 % from the Bhima River contaminated and females showing higher susceptibility. These findings emphasise the need for further research on MP impacts on human health and the development of mitigation strategies.

水产养殖图标 Oreochromis mossambicus 中的微塑料污染：普遍性、特征和综合概述。

全球塑料年产量激增至 3.68 亿吨，导致大量塑料废物堆积，预计到 2050 年将达到 12,000 兆吨，对水生生态系统造成影响。鱼类的蛋白质和营养至关重要，尤其容易摄入微塑料（MP）。作为一个主要的水产养殖生产国和水产品消费国，印度面临着日益严重的淡水塑料污染问题，这种污染会破坏鱼类的健康和生长，对水产养殖系统的可持续性和生产力构成重大威胁，并带来潜在的健康风险。本研究的重点是莫桑比克罗非鱼（Oreochromis mossambicus），该鱼类因其广泛的水产养殖用途、快速生长和营养价值而备受重视。我们的研究揭示了莫桑比克罗非鱼的重大 MP 污染（69.23%），其中乌尔哈斯河和比马河分别有 80% 和 60% 的罗非鱼受到污染，雌性罗非鱼的易感性更高。这些发现强调了进一步研究 MP 对人类健康的影响和制定缓解策略的必要性。

期刊介绍： Environmental Toxicology and Pharmacology publishes the results of studies concerning toxic and pharmacological effects of (human and veterinary) drugs and of environmental contaminants in animals and man. Areas of special interest are: molecular mechanisms of toxicity, biotransformation and toxicokinetics (including toxicokinetic modelling), molecular, biochemical and physiological mechanisms explaining differences in sensitivity between species and individuals, the characterisation of pathophysiological models and mechanisms involved in the development of effects and the identification of biological markers that can be used to study exposure and effects in man and animals. In addition to full length papers, short communications, full-length reviews and mini-reviews, Environmental Toxicology and Pharmacology will publish in depth assessments of special problem areas. The latter publications may exceed the length of a full length paper three to fourfold. A basic requirement is that the assessments are made under the auspices of international groups of leading experts in the fields concerned. The information examined may either consist of data that were already published, or of new data that were obtained within the framework of collaborative research programmes. Provision is also made for the acceptance of minireviews on (classes of) compounds, toxicities or mechanisms, debating recent advances in rapidly developing fields that fall within the scope of the journal.
