Soil pollution

WATER AND HEALTH

- May the sea-water be the cause of health hazards?

- Certainly. Today grave concern is expressed about the pollution of the sea with untreated domestic and industrial sewage. This concern is expressed with justification. Sea is the final cesspool into which most of the discharge of man’s pollution activities flows.

- What is the most important aspect of the pollution?

- The sea pollution problem has many aspects but in its essence it is a question of toxicology. The toxic effects of a chemical substance on a specific cellular system of an organism, be it a plant, an animal, or a man are manifold and harmful. Industrial pollution has proved disastrous to the fishery industry, especially, in certain regions.

- What is the present state of affairs with fish safety in general?

- Well, today it is very hard for big and small fish alike to survive in polluted water as they choke with refuse, ashes, chemical salts, tars, phenol and bacteria. In some places a layer of grease has formed on the surface of the water which prevents oxygen from penetrating through it.

- Can the fish from waste water be the direct threat to human health?

- Yes, indeed. It’s the mater of great concern. Public Health Service record (official report) has established that human poisoning and illness associated with eating contaminated fish and shell-fish multiply.

- What parts of the sea are most susceptible to pollution?

- The continental coastal regions and the insular shallow water areas in tropicl seas are. It’s just the part of the sea from which the world’s marine fishery products are derived.
