What are the main sources of microplastics found in Goa's coastal ecosystem?

Microplastics in Goa's coastal ecosystem originate from various sources, including disintegrated fishing gear, tire residue, packaging waste, electronic waste, human wastewater, and textiles.

How do microplastics affect the nutritional value of seafood in Goa?

The study found that 66 out of 71 shellfish species assessed had poor nutritional status due to microplastic contamination. This means the affected fish will not deliver as many nutrients to people who consume them, potentially compromising the overall health of the local population.

What are the health risks associated with consuming microplastics-contaminated seafood from Goa?

Consuming microplastics-contaminated seafood can lead to a range of health issues, from weakened immunity to cancer, in both humans and animals. Bioaccumulation of these toxic particles can have severe consequences for public health and wildlife populations.

Microplastics Ravage Goa's Coastal Ecosystem, Endangering Marine Life and Human Health

According to a recent study, scientists have uncovered a troubling presence of microplastics along Goa's coastline, with the issue permeating the entire estuarine food chain. The researchers, from the CSIR-National Institute of Oceanography and the Academy of Scientific and Innovative Research, focused their investigation on the bamboo shark, a top predator in the Mandovi estuarine system, which accounts for 97% of Goa's fish output.

The findings, published in the journal Environmental Research, reveal that anchovies and catfish had the largest accumulation of microplastic particles, with consumption being the primary mode of entry for these pollutants. In total, the researchers identified 4,871 polluting particles, including 3,369 plastic particles from 19 different polymers, 11 of which are classified as highly toxic.
