Now a days we are mostly facing Benzene Pollution. Before we go to the article we have to know what is benzene? How Benzenes are effecting our body? Let’s see
Benzene is a simplest organic, aromatic hydrocarbon and parent compound of numerous important aromatic compounds. It is a colourless liquid with a characteristic odour and is primarily used in the production of polystyrene. Benzene is highly toxic and is a known carcinogen; exposure to it may cause leukemia. As a result, there are strict controls on benzene emissions.
Natural sources of benzene include volcanoes and forest fires. Benzene is also a natural part of crude oil, gasoline, and cigarette smoke. Normal environmental concentrations of benzene are unlikely to damage animals or plants. It does have a low to moderate toxicity for aquatic organisms, but this is only likely to be apparent when high concentrations arise from significant spills.
The indoor benzene exposure is often higher than outdoor. The outdoor air usually contains a low level of benzene from tobacco smoke, gas stations, motor vehicle exhaust, and industrial emissions. The benzene in indoor air comes from products such as glues, paints, furniture wax, and detergents. Further, fuels such as coal, wood, gas, kerosene or liquid petroleum gas (LPG) for space heating and cooking also lead to higher benzene concentration indoors. Polyurethane is used majorly its two major applications, soft furnishings and insulation. Its thermal decomposition consists mainly of carbon monoxide, benzene, toluene, oxides of nitrogen, hydrogen cyanide, acetaldehyde, acetone, propene, carbon dioxide, alkenes and water vapor.
