It is interesting to note that aldrin, dieldrin, endrin, heptachlor, HCB, mirex, and chlordane have never been used in or imported to Estonia.
O'LEARY, AN ASSESSMENT REPORT ON: DDT, ALDRIN, DIELDRIN, ENDRIN, CHLORDANE, HEPTACHLOR, HEXACHLOROBENZENE, MIREX, TOXAPHENE, POLYCHLORINATED BIPHENYLS, DIOXINS AND FURANS [section] 6.7 (1995), available at http://www.chem.unep.ch/pops/indxhtms/asses6.html.
That group had measurable levels of DDE (3.2 ppb) and nondetectable levels of mirex (< 0.3 ppb).
The 12 pollutants to be covered by the treaty are the pesticides aldrin, chlorodane, DDT, dieldrin, endrin, heptachlor, mirex, and toxaphene, the industrial chemicals hexachlorobenzene and polychlorinated biphenyls (PCBs), and dioxins and furans, which are unwanted byproducts of combustion and industrial processes.
The 12 -- PCBs, DDT, dioxins, chlordane, furans, hexachlorobenzene, aldrin, mirex, dieldrin, toxaphene, endrin and heptachlor -- are all organochlorines and most are pesticides.
The chemicals, known as "bioaccumulative chemicals of concern" (BCCs), include mercury, polychlorinated biphenyls or PCBs, dioxin, chlordane, DDT, and mirex. Browner said, "The risks posed to human health and to the Great Lakes themselves by these toxic pollutants are simply too high to ignore.
The company's Mirex thermoforming sheet extrusion system, which uses a horizontal polishing stack and a grooved feed extruder, can produce polypropylene, HIPS, and PET sheets without a change in hardware.
The eels may be the reason the belugas are contaminated with Mirex, a now-banned organochlorine pesticide that was once used against fire ants.
(1995), we calculate forage fish to lake trout BMFs of 10.7 for Mirex, 7.7 for DDE, and 7.9 for PCBs.
PCB, mirex, heavy metals and other persistent chemicals find their way into aquatic life and fish-eating predators, cycling continually through the ecosystem.
