Manufacturing industries are the main polluters and degraders of environment, Industries create fourtypes of pollution namely air, water, land and noise.
Role of Industries in Air Pollution.
a) Smokes emitted are the main pollute air and water very badly.
b) Air pollution is caused by the presence of a higher proportion of undesirable gases such as carbon monoxide and sulphur dioxide, which is found in smoke emitted by industries.
c) Dust, fuma mist, spray and smoke which contain both solid and liquid particle are air. Born particulate materials which pollute the air.
d) Human made sources of pollutants are normally industrial and solid wastes, which have their share in the pollution of air.
Role of Industries in Water Pollution.
a) The smokes emitted by the industries pollute water very badly.
b) The second is industrial effluents that are discharged tint rivers. They are both organic and inorganic.
c) Coal, dyes, pesticides, fertilizer, plastics and rubber are some common pollutants in water.
d) The principal industries which create water pollution are paper pulp, textile, chemical, petroleum refining, tannery and electroplating.
Role of Industries in Land Pollution.
a) Industrial wastes containing toxic metals pollute land and soil.
Role of Industries and means of Transport.
a) Noise pollution arisis primarily form industries and means of transport.
b) Industrial noise particularly from mechanical saws and pneumatic arms is unbearable and is a nuisance to the public. Noise causes impairment of hearing.
