vehicular pollutant have damaging effects on both human health and
ecology. The health effects of pollution vary in the degree of severity,covering
a range of minor effects to serious illness, as well as premature
death in certain cases. These pollutants are believed to directly
affect the respiratory and cardiovascular systems. In particular,
high levels of Sulphur dioxide and Suspended Particulate Matter are
associated with increased mortality, morbidity and impaired pulmonary
Pollutant Effect on Human Health
Affects the cardio vascular system, exacerbating cardiovascular
disease symptoms, particularly angina; may also particularly affect
fetuses, sick, anemic and young children, affects nervous system
impairing physical coordination, vision and judgments, creating
nausea and headaches, reducing productivity and increasing personal
Increased susceptibility to infections, pulmonary diseases, impairment
of lung function and eye, nose and throat irritations.
Affect lung function adversely.
Particulate Matter and Respirable Particulate
Matter (SPM and RPM)
Fine particulate matter may be toxic in itself or may carry toxic
(including carcinogenic) trace substance, and can alter the immune
system. Fine particulates penetrate deep into the respiratory system
irritating lung tissue and causing long-term disorders.
Impairs liver and kidney, causes brain damage in children resulting
in lower I.Q., hyperactivity and reduced ability to concentrate.
Both toxic and carcinogenic. Excessive incidence of leukemia (blood
cancer) in high exposure areas.
