Air pollution 1. The smoke emitted by the industries pollute air and water very badly. 2. This pollution is caused by the presence of a higher proportion of undesirable gases, such as carbon monoxide and sulphur dioxide. 3. Dust, fume, mist, spray and smoke released from the industries contain both types of particles: (a) solid, (b) Liquid. 4. This pollution is very harmful for human health, as well as for animals, plants, materials and for the atmosphere. Water pollution 1. Sources for this pollution are numerous. However its main source is the organic and inorganic discharge from the industries. 2. The principal industries creating water pollution are paper, pulp, textiles, chemicals, petroleum, refining tannery and electroplating. Land pollution – Land and soils is polluted by the industrial wastes containing toxic metals. Noise pollution – Land and soil is polluted by the industrial wastes containing toxic metals. Noise pollution 1. It is very harmful, it causes impairment of hearing as well as many other physiological and psychological problems. 2. Industrial noise, particularly from mechanical saws and penumatic drills cause unbearable sound. 3. Despite of all its harmful effects, industrial work can’t be stopped. On the other hand much of the pollution can be prevented be carefully planning and siting of industries, better design equipment and better operation of the equipment. |
| (iii) Discuss the steps to be taken to minimise environmental degradation by industry. Answer – The following steps can be taken to minimise environmental degradation by the industry – (i) minimising use water for processing by reusing and recycling it in two or more successive stages. (ii) harvesting of rainwater to meet water requirements. (iii) treating hot water and effluents before releasing them in rivers and ponds. Treatment of industrial effluents can be done in three phases. (a) Primary treatment by mechanical means. This involves screening, grinding, flocculation and sedimentation. (b) Secondary treatment by biological process. (c) Territary treatment by biological, chemical and physical processes. |
