(2010, October) Environmental assessment of remediation technologies: an analytical framework for a hexachlorocyclohexane
(HCH) contaminated site in Brazil.
Until recently the pesticides used included such dangerous products as DDT and hexachlorocyclohexane
, which are highly stable and very persistent in the environment.
The groups said they detected PCB, DDT, the insecticide hexachlorocyclohexane
and other chemicals.
Low levels of hexachlorobenzene (HCB), hexachlorocyclohexane
(HCH), oxychlordane, trans-nonachlor, p.p'-DDD, and p,p'-DDT were also reported in a few samples.
This article outlines the determining factors and uses hexachlorocyclohexane
(HCH) to illustrate the situation.

The general strategy for water protection and the prioritized dangerous substances to be controlled includes hexachlorobenzene (HCB), hexachlorocyclohexane
(HCH, lindane), polycyclic aromatic hydrocarbons (PAHs), pentachlorobenzene, and pentachlorophenol (PCP) with the aim of protecting the health of the general population [13,14].
These chemicals were traced to three pesticides UCIL manufactured -- Carbaryl ( brand name Sevin), Aldicarb ( Temik) and a formulation of Carbaryl and gamma- hexachlorocyclohexane
(HCH) isomers and chiral signatures of a-HCH in the Arctic marine food web of the Northwater polynya.
