Disruption of androgen regulation in the prostate by the environmental contaminant hexachlorobenzene
and PCB concentrations in cricket frogs were similar to values reported for other amphibians within the geographic range of Blanchard's cricket frogs (Russell and others 1997).
Our observations with the TMS-enol-TMS ether derivatives of four model anabolic steroid metabolites and the (3-agonist clenbuterol extracted from a urine matrix mirrored those of the hexachlorobenzene
These chemicals included hexachlorobenzene

The Convention's list includes the following hazardous pesticides: 2,4,5- T, aldrin, binapacryl, captafol, chlordane, chlordimeform, chlorobenzilate, DDT, DNOC and its salts, ethylene dichloride, ethylene oxide 1,2-dibromoethane (EDB), dieldrin, dinoseb, fluoroacetamide, HCH, heptachlor, hexachlorobenzene
, lindane, mercury compounds, monocrotophos, parathion, pentachlorophenol and toxaphene, plus certain formulations of methamidophos, methyl-parathion, and phosphamidon, as well as dustable-powder formulations containing a combination of benomyl at or above 7 per cent, carbofuran at or above 10 per cent and thiram at or above 15 per cent.
When first drafted in 2000, this treaty looked to curb what many scientists referred to as the dirty dozen: dioxins, furans, polychlorinated biphenyls (PCBs), and the pesticides aldrin, chlordane, DDT, dieldrin, endrin, heptachlor, hexachlorobenzene
, mirex, and toxaphene (SN: 12/16/00, p.
In one of five products claiming to contain Korean ginseng, a high amount of the pesticide hexachlorobenzene
The researchers have also found that women with breast cancer are nine times as likely to have detectable amounts of the pesticide hexachlorobenzene
(HCB) in their blood.
Nine of the 12 (aldrin, endrin, dieldrin, chlordane, DDT, heptachlor, hexachlorobenzene
, mirex, and toxaphene) are pesticides, all of which have been targeted for elimination by nongovernmental organizations (NGOs) around the world since the early 1980s as part of Pesticide Action Network (PAN) International's Dirty Dozen campaign.
