each of the questions. (14pts)

Pollution emitted in industrial areas represents a threat to human health and the surrounding natural

resources. We have a tendency to believe that the production processes are the only source of environmental

damage, and often forget about the possible long-term effects of harmful production practices. We may

think that the closure of these huge industrial areas would improve the quality of the environment.

Unfortunately, this ignores the threat of the remaining waste, which is abandoned and poorly stored.

It

represents an even bigger danger because it stands neglected as it degrades and leaks into the earth without

any control at all.

Changes in the water chemistry due to surface water contamination can affect all levels of an

ecosystem. It can affect the health of lower food chain organisms and, consequently, the availability of food

up through the food chain. It can damage the health of wetlands and damage their ability to support healthy

ecosystems, control flooding, and filter pollutants from storm water runoff. The health of animals and

humans are affected when they drink or bathe in contaminated water. In addition water-based organisms,

like fish and shellfish, can pile up and concentrate contaminants in their bodies. When other animals or

humans eat these organisms, they receive a much higher dose of contaminant than they would have if they

had been directly exposed to the original contamination.

Contaminated groundwater can badly affect animals, plants and humans if it is removed from the

ground by manmade or natural processes. Depending on the study of rocks of the area, groundwater may

rise to the surface through springs or seeps, flow sideways into nearby rivers, streams, or ponds, or sink

deeper into the earth. In many parts of the world, groundwater is pumped out of the ground to be used for

drinking, bathing, other household uses, agriculture, and industry.

Contaminants in the soil can harm plants when they take up the contamination through their roots.

Eating, breathing in, or touching contaminated soil, as well as eating plants or animals that have piled up soil

contaminants can badly affect the health of humans and animals.

Air pollution can cause breathing-related problems and other bad health effects as contaminants are

absorbed from the lungs into other parts of the body. Certain air contaminants can also harm animals and

humans when they contact the skin. Plants rely on breathing for their growth and can also be affected by

exposure to contaminants moved in the air.
