Consequences of industrial wastes dumped in water?

Discharges are the main source of coastal pollution.

In

most of the developing countries and in many developed places, the

discharges of the cities are usually done directly to the sea, without

previous purification treatments.

In addition, areas where water renewal is slower (marshes, estuaries, bays, harbors) are the most abused.

They are frequently found fish with tumors and serious diseases, or

mollusks and crustaceans whose fishing and consumption are prohibited,

because they contain high doses of toxic products.

The residues that come from the petroleum derivatives are forming a film.

Some toxic substances that poison the plankton, fish and various aquatic organisms.

This kind of substance destroys animals and plants, and breaks the natural balance.

These

contaminants are deposited in the human body, and in some cases do not

cause death, but diseases, malformations, poor development, etc.
