Over half of cyanazine
-exposed applicators had [greater than or equal to] 6 years of exposure at enrollment, and approximately 85% had begun using cyanazine
before the 1990s.
Detection rates for herbicides ranged from 0% for metribuzin and cyanazine
to 95% for 2,4-dichlorophenoxyacetic acid.
Effects of the chlorotriazine herbicide, cyanazine
, on GABA(A) receptors in cortical tissue from rat brain.
The authors concluded that atrazine, metolachlor, and cyanazine
were each significant predictors of intrauterine growth retardation and that areas with drinking water containing higher herbicide concentrations had higher rates of intrauterine growth retardation than nearby communities with other sources of drinking water.
Chloro-s-triazines, introduced in the late 1950s, include atrazine (ATR), simazine, propazine, terbutylazine, and cyanazine
(Worthing and Walker 1987).
Cancer incidence among pesticide applicators exposed to cyanazine
in the Agricultural Health Study.
Herbicides which were not detected during any sampling event included hexachlorocycolpentadiene, propachlor, desethylatrazine, trifluralin, desisopropylatrazine, hexachlorobenzene, clomazone, pentachlorophenol, lindane, terbufos, heptachlor, chlorpyrifos, cyanazine
, aldrin, pendimethalin, heptachlor epoxide, oxychlordane, gamma-Chlordane, alpha-chlordane, trans -Nonachlor, dieldrin, endrin, cis-Nonachlor, p,p'-DDT, bis (2-ethylhexyl) adipate, methoxychlor, bis (2-ethylhexyl) phthalate, and benzo[-a]pyrene.
In a few cases substances were found in concentrations that may cause adverse effects to aquatic life, with the herbicide cyanazine
being the most frequently detected at concentrations exceeding the Dutch water quality guidelines .
EPA's November 1994 decision to initiate a special review of the triazine herbicides, including atrazine, simazine and cyanazine
Atrazine is the flagship of the triazine class of herbicides, which includes cyanazine
pesticides (herbicides, insecticides, and their degradation products) such as Aldicarb, Chlordane, Atrazine, metolachlor, cyanazine
, and metalaxyl (Suffolk County Department of Health Services 2000)
Pesticide samples were extracted via Solid Phase Extraction (SPE), and analyzed for fifteen different pesticides using GC-MSD: triclopyr, 2,4-D, tebuthiuron, simazine, atrazine, metribuzin, alachlor, metolachlor, cyanazine
, norflurazon, hexazinone, pendimethalin, DDT insecticide degradation product p,p'-DDE, diuron, and fluometuron.
