Air pollution is a general term used to describe undesirable amounts of particulate or gaseous substances in the atmosphere. APCD's primary focus is to reduce pollution to prescribed levels that protect public health. Although reduced visibility may be the more obvious effect of air pollution, the health problems it causes are by far more serious.
