Abstract: | Background, aim, and scope Lindane, technically 1, 2, 3, 4, 5, 6-hexachlorocyclohexane (γ- HCH), is the most commonly detected organochlorine pesticide
from diverse environmental compartments. Currently, India is the largest consumer and producer of lindane in the world. The
production of lindane results in the generation of large quantities of waste HCH isomers (mainly α-, β- and δ-). All these
isomers are toxic and have a long-range environmental transport potential. The aim of this study was to monitor the seasonal
variation of HCH isomers in an open soil–plant–rhizospheric soil system of a contaminated industrial area. For this, selected
plant species and their rhizospheric soil (soil samples collected at a depth range of 0–45 cm near to the root system) and
open soil samples (soil samples collected (0–30 cm depth) from 1–1.5 m away from the plant root system) were collected for
2 years (two summer seasons and two winter seasons). |
