Lindane, or gamma-hexachlorocyclohexane, is a persistent organochlorine pesticide. It is a highly chlorinated organic pollutant that has been widely used as an insecticide for hardwood logs, lumber, and crops. Its chemical formula is C6H6Cl6, and it has a molecular weight of 290.83 g/mol. Lindane is considered a priority pollutant and hazardous substance by the US EPA and WHO. It has been banned in most developed countries since the 1970s due to its toxic effects on human health and the environment.
Lindane has a wide variety of toxicological effects, including reproductive and endocrine impairments, and it is considered a possible neurotoxin, endocrine disruptor, and human carcinogen. It is particularly toxic to aquatic organisms and has been found to bioaccumulate in the adipose tissue of organisms, including fish, seals, and polar bears. The long-range transport of Lindane is evident by its presence in the Arctic, where it has never been used.
Surface waters near industrialized and agricultural areas are often contaminated with Lindane and other pollutants. The runoff from HCH factories and waste dumpsites can pollute ground and surface waters, affecting aquatic ecosystems and the health and safety of indigenous peoples who rely on these ecosystems for their traditional diets. Lindane residues have also been detected in maternal serum, the placenta, the umbilical cord, and cord serum, raising concerns about potential exposure to the unborn fetus.
The persistence of Lindane in the environment is due to the presence of recalcitrant chlorine groups. It is mostly concentrated in water, although significant amounts can also be found in soil/sediment and air. The European Union has set maximum permissible limits for Lindane in drinking water and surface water to protect human health and the environment. However, some regions, such as Amangarh in the Peshawar valley, have detected Lindane concentrations beyond the acceptable levels.
Overall, Lindane is a persistent and toxic organochlorine pesticide that poses a significant risk to human health, aquatic ecosystems, and the environment. Its widespread use and persistence have led to its presence in remote regions and the bioaccumulation in various organisms. While some countries have restricted or banned its use, global efforts are needed to phase out this dangerous pollutant and mitigate its impacts.
