What are some of the environmental pollutants and their effects on health?

Contamination is a determining factor in the deterioration of the quality of life.

The quality of the air is determined by the presence or absence of various substances and their concentrations.

Lead is a very potent poison that until recently was present in gasoline and house paint.

The composition of the air determines its quality and suitability for certain activities.
