What’s more concerning is that plastic has been found to act like a sort of sponge, concentrating toxic chemicals that are diluted in oceans and lakes. Such toxins include heavy metals and chemicals that have long been banned, such as DDT or PCBs, that can have severe environmental effects and are known to cause cancer and birth defects.

The fish, which are found in the ocean’s gyres, come to the surface to feed at night, where they ingest the plastic particles which resemble the size of their usual prey.
Several samples of the myctophids uncovered significant loads of plastic the size of appropriate particles inside the guts of the animal.
