Lindane is an organochlorine compound, having wide range of application in pest control, vector control and in medical field
for treatment of head lice and scabies. Chemically, Lindane is the gamma isomer of 1, 2, 3, 4, 5, 6 Hexachlorocyclohexane
(γ-HCH). Pertaining to its toxicity, persistency and potential carcinogenic effect, its usage has been banned in several countries.
However many developing countries are still using Lindane for economic reasons. Owing to unregulated production, usage and
unsound disposal practices, γ-HCH has become ubiquitous environmental pollutant posing serious toxicological threat to public
health and environment. Hence remediation of Lindane contaminated sites has become one of the most pervasive problems in
environmental management. In view of this, herein an integrated approach has been proposed for remediation of Lindane. This
integrated approach involves the use of microbial cells along with iron nanoparticles for degrading Lindane, thus exploiting the
reductive capabilities of both biotic as well as abiotic processes. Experimental studies revealed that biotic and abiotic processes
acts synergistically in integrated system displaying higher Lindane removal efficiency as compared to individual processes. Thus
integrated approach could be used as a potential remediation tool for managing Lindane contaminated sites. The encouraging
results obtained in this study should promote further research into applying integrated techniques to other isomers of HCH as
well as other chlorinated contaminants.
