चर्चा में क्यों
Researchers at V.O. Chidambaram College identified that nylon fibers are the dominant microplastic in Chennai's coastal ecosystems, posing significant ecological risks to marine life.
पृष्ठभूमि
A study by V.O. Chidambaram College in Thoothukudi found that microplastics in Chennai, while lower in abundance than some global sites, pose high ecological risks. Nylon fibers were identified as the dominant microplastic type causing harm through ingestion and chemical pollution.
प्रीलिम्स के लिए तथ्य
- स्थानV.O. Chidambaram College is located in Thoothukudi, Tamil Nadu
- तथ्यNylon fibers are the dominant type of microplastic found in Chennai's coastal ecosystems
- पर्यावरणMicroplastics in Chennai pose ecological risks to marine life and coastal ecosystems
मेन्स के लिए
Q. Discuss the ecological implications of microplastic pollution in coastal ecosystems and suggest measures to mitigate the impact on marine biodiversity.
उत्तर के आयाम
- Ecological risk: Bioaccumulation of nylon fibers in marine organisms through ingestion
- Waste management gap: Inadequate filtration and waste processing leading to microplastic leakage
- Policy intervention: Need for regulated fishing practices and public awareness to curb plastic influx
