Sea pollution
Heavy metal pollution
The most dangerous are: cadmium, lead, mercury that can be harmful to human health even in very low concentrations, as well as being highly toxic and non-degradable. They accumulate in those organisms that occupy the highest levels in the food pyramid: mercury pollution in the sea provokes the concentration of this metal in fish and the organisms that eat the fish, including men. Mercury that derives from the dumping of industrial waste and that reaches the sea is ever lasting and continues its cycle by passing from one organism to another through the food chain.
