To account for the above-mentioned air-pollution phenomenon, a couple of severe reasons should be pointed out. On the one hand , the severely polluted air industrial wastes have been pumped into the air, the lakes and rivers and an increasing number of automobiles crowd into the streets and produce the gas emission.
