Potential human health hazards

ABSTRACT

In our daily life we come in contact with innumerable chemicals and materials of which we have no knowledge about their toxicity. Sources of polyvinyl chloride [PVC], dioctylphthalate [DOP], Poly chlorinated biphenyls [PCBs], perta chloropherol [PCP], dioxin, formaldehyde and plastics have been identified in various items of daily use. ILL-effects of these materials have been discussed in detail in this article. Metallic contaminants such as lead, cadmium, arsenic, nickel have been identified in a number of non-conventional sources. Effects of nitrites, nitrates, nitrosamines have also been discussed. It is suggested that strict measures should be adopted to control the menace of such materials. Standards set by the developed countries should not be relaxed at any cost
