Nano-sized plastics originate from direct release of nanoparticles or from degradation of discarded plastic and mainly enter the aquatic food chain through uptake by algae or herbivorous invertebrates, and then continue up the food web.

Aquatic microphytes are pioneer organisms of an aquatic food chain. The productivity of an aquatic environment depends on the density of microphytes. These produce the food material on which other organisms in the ecosystem sustain. In this context, the present investigation was undertaken to study the diversity of microphytes from some reservoirs (Belawale Budruk, Benikare, Karanjivane, Sonali and Murgud) of Kolhapur District, Maharashtra. About 108 species of microphytes were identified from these lakes. Maximum diversity is observed from Chlorophyceae, followed by Bacillariophyceae and Cyanophyceae.

Before humans inserted themselves into the aquatic food chain, sharks were at the top maintaining balance and playing a crucial role on this earth. For hundreds of millions of years (even before the dinosaurs!) sharks have been shaping our underwater ecosystem and creating a foundation for life in all parts of the sea. Now with 95% of shark populations decreasing everywhere our health and the planet's health is at major risk. Shark livers contain an oil so hydrating and rich all cosmetic that companies want to get their hands on it. This simple substance, also known as squalene, is found all around the world in the form of cosmetics (lotions, anti-wrinkle creams, sunscreen, foundations) and daily off the shelf supplements. With the serious lack of education about what’s in our cosmetics, it makes it scary to think that almost all of us have been absentmindedly plastering on prehistoric predators on our body in the name of beauty.

This article presents the results of experiments on the transitions of Fe3O4 nanoparticles (20–30 nm) and Al (18 nm) from one organism to another, making up a simple food chain (plant–mollusk–fish). In experiments, mollusks (Melonopsis praemorsa) feed on the leaves of plant (Elodea canadensis) after being contaminated with Al or Fe3O4 nanoparticles. Nanoparticles were detected using TEM analysis in the cells of the mollusk’s organs. Then the fish (Oncorhynchus mykiss) were fed with mollusks. The distribution and localization of nanoparticles in fish organs has been determined. Experimental results showed that nanoparticles can pass from one organism to another in the food chain. Nanoparticles accumulate mainly in the liver of mollusks and fish.
