Hexachlorobenzene

Hexachlorobenzene, originally used to prevent wheat bunting, is produced as a byproduct in the production of chemicals related to chlorine and could potentially be present as an impurity. Multitudes of interrelated health effects of HCBs have been reported. Considered a probable human carcinogen, all routes of administration for HCBs are regarded as toxic. The most sensitive indications of these chemical substances have reportedly been found to be hepatotoxicity and immunotoxicity. In Indian context, the detection of HCB levels in environmental samples analyzed for different cities is quite low which is in line with predictions published in previous studies that HCB emissions will decrease considering improved chemical and metal manufacturing and handling methods of growing nations. Despite the substance’s use being prohibited for many years, HCB contamination clean-up continues to be a problem for the environment. A number of methods can be used to get rid of HCB traces in soil and sediment. There is a lack of literature on the extensive and pilot scale remediation of HCB-contaminated soils, sediments, and waters. Thus, the focus of recent studies has been notably on pilot-scale electro kinetic remediation. Still, additional data is needed for estimating the equivalence factors between the consequences and their toxic potential.
