Reversal of the air-water gas exchange direction of hexachlorocyclohexanes
in the Bering and Chukchi Seas', Environmental Science and Technology, 29:1081-1089, 1995.
214) It immediately banned production and use of eight of these POPs,(215) and it identified four other POPs (DDT, heptachlor, hexachlorocyclohexanes
, and PCBs) that will be eliminated at a later stage.
Concentrations of hexachlorobenzene (HCB) fell by 40 to 50% between 1981 and 1991, but those of [alpha]- and [gamma]- hexachlorocyclohexanes
(HCH) did not change.
The second looks more specifically at the presence of pesticides - hexachlorocyclohexane
(HCH, lindane) and brominated flame retardants such as polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCD).
Substances currently covered only by the UN/ECE Protocol (those marked with an asterisk are those that the Commission proposes to be included in the Stockholm Convention, too): chlordecone*, hexabromobiphenyl*, hexachlorocyclohexane
(HCH, including lindane)*, polycyclic aromatic hydrocarbons (PAH),
Hexachlorobenzene (HCB), p,p'-DDE, gamma hexachlorocyclohexane
([gamma]-HCH), trans-nonachlor, and PCBs 138, 153, and 170 were the most frequently detected OCs in fat and liver.
The subchronic oral toxicity of the [beta]-isomer of hexachlorocyclohexane
2007) observed no association between living within 60 m of an agricultural field and higher serum levels of the organochlorines dichlorodiphenyltrichloroethane (DDT), dichlorodiphenyldichloroethene (DDE), hexachlorocyclohexane
(HCH), and hexachlorobenzene (HCB); however, these pesticides had been banned or restricted in the United States prior to the study period, and serum levels were mainly related to birth in Mexico, where the organochlorines have had more recent use.
