Frontiers in Marine Science 2024 17 citations

AI summary Read the abstract

This review provides a comprehensive look at microplastic pollution in India's marine environment, covering sources, transport, effects on marine life, and potential solutions. Microplastics are being ingested by organisms at every level of the food chain, causing inflammation, hormonal disruption, and reproductive problems that eventually affect humans through seafood. The authors call for stronger policies, better waste management, and public awareness to address this growing threat to both marine ecosystems and human health.

Microplastic pollution has emerged as a significant environmental challenge globally, posing threats to biodiversity, marine life, and human health. Studies indicate that marine organisms, from plankton to larger fish species, and ultimately humans are ingesting microplastics, leading to physiological harm such as inflammation, digestive blockages, tissue injury, hormonal imbalance, reproductive failure and biomagnification through the food chain. Therefore, there arises an urgent need and demand for implementing effective and sustainable remediation solutions. Though, various mitigation technologies are developed, less information is available on the advantages and disadvantages of the technological advancements. The present review highlights the significant information available on the sources, types, transport of microplastics along with the analytical methods to detect the microplastic pollutions. The global perspective of microplastic pollutions with respect to Indian Marine scenario was highlighted. The recent and advanced mitigation technologies and solutions in preventing, reducing and recycling these microplastic pollutions were also addressed. This review further underscores the need for comprehensive strategies to monitor, manage and mitigate microplastic pollution, including policy interventions, public awareness campaigns, and sustainable waste management practices. Addressing this issue is essential for preserving the health of India’s marine ecosystems and safeguarding the livelihoods of mankind.

Incorporation of Microplastics into Food Chains and their Consequences on marine Biodiversity: An Emerging Environmental Challenge in Maharashtra, India

AI summary Read the abstract

This review pulls together existing research showing that tiny plastic bits (microplastics) are building up along India's Maharashtra coast and getting eaten by plankton, shellfish, and fish—including the kinds of seafood people eat. These plastics can harm marine life by causing inflammation, hormone disruption, and other health problems, and they can also carry toxic chemicals up the food chain, raising concerns about what ends up on our plates. The findings underscore the need for better monitoring and pollution controls to protect both ocean ecosystems and the seafood-based diets many communities depend on.

Effects of marine microplastic on marine life and the food webs – A detailed review

AI summary Read the abstract

This review provides a comprehensive look at microplastic pollution in marine environments, covering sources, impacts on marine life, and risks to human health through the seafood supply chain. Microplastics cause physical harm like gut blockages in marine animals and can carry toxic chemicals that accumulate up the food chain. The authors emphasize that with global plastic production still rising, urgent policy action and better waste management are needed to protect both ocean ecosystems and human health.

Microplastic Pollution in India's Marine and Inland Environmental Matrices: A Comprehensive Review

AI summary Read the abstract

This review pulls together existing research showing that tiny plastic fragments called microplastics are widespread in India's rivers, coastlines, and drinking water sources, and that fish and other seafood are absorbing them too. This matters because when we eat contaminated seafood or drink affected water, we may be ingesting these particles ourselves, though scientists are still working to fully understand the health effects. The review mainly highlights gaps in current research, signaling that more studies are needed to pin down exactly how risky this contamination is for people.
