Nanoplastic Pollutants Affecting Fisheries Sector All Over the World
AI summary Read the abstract
This review addresses the emerging threat of nanoplastics to global fisheries, summarizing evidence for their presence in marine environments, uptake by fish, and the analytical challenges of detecting nanoscale particles in fisheries species.
Future environmental hazards from developing pollutants like nanoplastics cannot be disregarded. There is general agreement that these are not only present in the environment - either directly released or as a result of weathering of larger fragments - but that they pose a serious threat to the environment and human health, as well. However, their presence has been difficult to adequately ascertain due to the inherent technical difficulties for isolating and quantifying them. These particles are suitable for consumption by species at the bottom of the food chain due to their smaller size. Furthermore, because nanoparticles often have a high surface area to volume ratio, additional pollutants, like persistent organic pollutants, may be adsorbed and subjected to bioaccumulation and bio-amplification events. Recent discussions among scientists, policymakers, and the general public have focused on nanoplastics since the weathering of macroplastics could result in a significant load of nanoplastics in different ecosystems. This chapter will put light on the adverse effects caused by nanoplastics accumulation in the aquatic environment that is the subject of concern today and some of the remediation processes with special reference to microbial remediation.

Toxicity of nano- and microplastics on marine and freshwater fish: A multi-scale perspective from organ systems to cells
AI summary Read the abstract
This review pulls together existing studies showing that tiny plastic particles (micro- and nanoplastics) can build up in fish, damaging their gut, gills, heart, brain, and immune system by causing inflammation and cellular stress. While this research was done in fish, it matters for us too, since these plastics are widespread in water and seafood, and fish share many biological similarities with humans, meaning our bodies could face similar risks from ongoing plastic exposure.

Exploring the detrimental effects of nanoplastics on ecosystems and human health
AI summary Read the abstract
Tiny plastic particles called nanoplastics, so small they can pass through cell walls, have been found everywhere from polar ice to human tissue, and this review pulls together existing research on how they might harm both the environment and our bodies. While scientists are still working out the exact health risks, the concern is that these particles could build up in our organs over time, which is why researchers are calling for more study and better plastic waste management. The takeaway: plastic pollution isn't just an environmental issue anymore, it's becoming a personal health question too.
