Microbeads are tiny, smooth, plastic spheres found in common household products such as facial soap. These beads, measuring from 0.0004 to 1.24 mm, roughly the size of some fi sh eggs, are too small to be removed by water treatment systems. Thus, they end up in rivers, lakes, and other bodies of water. The accumulation of these microbeads is an environmental concern for aquatic biologists because microbeads

a) make the lakes and rivers cloudy and dirty, affecting their appearance

b) may stick to some household water pipes, preventing drainage problems

c) could be mistaken for food by some species, working their way up the food chain

d) could clog fishing nets, affecting the ability of fishermen to catch fish

c) could be mistaken for food by some species, working their way up the food chain

Explanation:

Microbeads seem to take the appearance of fish eggs, of which some aquatic organisms usually feeds on these fish eggs on a normal day. So, these microbeads could be mistaken to be food source by some species, thereby ingesting these microbeads which could be a source of problem to their system and could district the ecosystem of such habitat. Hence, this poses a serious environmental concern for aquatic biologists.

affects the water bodies: excessive use of fertilizers causes eutrophication. the fertilizers which are used on plants affect the quality of land on which it is used, further causing erosion of soil. the fertilizers used on plants contain harmful chemical fumes which affect the environment.
