It was afternoon. Some children were playing in the field suddenly their ball was fallen in the nearby cannel. After trying a couple of minutes they were able to grab the ball again with some hazardous chemicals which  includes, acids, dispersants, alkalis, dyes (azo, anthraquinone, methine, nitro, arilmethane, carbonyl and others), heavy metals, organic-chlorines, pigments, salts, and do on . Now the question rises where did the hazardous chemicals come from? And the answer is well known to all of us, yes!!!! The industrial flourishing result in the areas like Savar and Narayangonj , Dhaka , Bangladesh.

The source of the wasted and polluted water is from the conduit of the textile industries and what more will surprise you is most the industries don?t the waste water treatment plant. They release the water untreated into the aqueduct which leads into ponds, cannels and eventually in river leaving a potential damage to the both human health and eco system. Moreover, some of the other industries also established near to the small cannels and rivers so that they can release the water untreated these industries includes tanneries, poultry farms, rerolling mills etc. Even household waste water and dry waste materials are also dumped directly into the cannels and rivers.

We all know that the waste water mainly from textile industries has reciprocal relationships with human health and eco system. The water from dying industries largely contains some mutagens such as azo dyes long exposure to it can cause cancer. Some of the other chemicals contain hepatotoxic elements which mainly lead to liver cirrhosis. And , it has been seen that many people are suffering from fatal disease , though it is not proved that the mangy environment is responsible but it can be said that some of the industrial waste contains raucous elements which could be a major player behind the renal diseases. The people who live nearby always suffer from chronic skin diseases. But, the most alarming fact is that from this waste water some gruesome noxious gases are emitted including the gases which contains Sulphur dioxide, Nitrogen dioxide, Ozone, Ammonia and Chlorine.
