The chemical industry and its processes are responsible for many of the useful products that we use in our everyday life. Things that we consider essential to living our everyday lives would not be available if there was no chemical industry. Cars, fabricated building materials, medicines, plastics and many other functional products would be unavailable.
Although the chemical industry is responsible for all these beneficial things the by-products and costs of chemical processes ultimately affect the whole world in a detrimental way. The direct effects of chemical processes are evident in the amounts of CFCs (chlorofluorocarbons), dioxins and pesticide residues. Environmental concerns such as acid rain, the depletion of the ozone layer, smogs and chemical spills are all by-products and resultants of the chemical industry and its processes in producing their products.
Fertilisers and pesticides:
Fertilisers are chemically manufactured in order to provide nutrients for plants and crops. Fertilisers contain chemicals, which may help the plants to grow faster, healthier and more resistant to diseases and insects. Pesticides are dangerous toxic chemical compounds that are sprayed on crops. Pesticides are usually sprayed on crops to prevent them from being eaten by pests such as locusts and other grubs. A widespread deadly insecticide is DDT; DDT's main purpose was kill disease carrying insects especially the malaria carrying mosquito. The chemical molecular formula of DDT is C14H9Cl5 and it is manufactured in industries by reacting chlorobenzene together with trichloro-acetaldehyde in the presence of sulfuric acid. DDT is an Organochloride, it is colourless and odourless and almost every piece of matter on Earth contains traces of DDT within it.
Before DDT was found to be as potent and dangerous as it was it was used commonly as a commercial and industrial insecticides. The side effects of DDT were that it settled everywhere. At one stage clouds of DDT were present in the suburban cities, the huge amounts of DDT were gradually reduced when its toxic properties were found out.
Additionally, the remaining traces of DDT still present in soils can contaminate many present day crops or grazing lands which livestock eats. These crops and livestock are then processed and sold in the market. This causes a huge impact on the health and welfare of consumers, which may lead to food poisoning, illnesses and other diseases. Some organochlorins have caused the weakening of oestrogenic activity in animals, affecting the birth and survival of offspring. Which ultimately affects the ecology of nature as well.
Aerosols and CFCs:
Chlorofluorocarbons (CFCs) are non-toxic, inflammable chemicals containing atoms of carbon, chlorine, and fluorine. They can be used in the manufacture of aerosol sprays, propelling agents in spray bottles, blowing agents for foams and packing materials, as solvents and as refrigerants. CFCs are classified as halocarbons, a class of...
