What I found most troubling was the number of
atrazine lineage rats in the F3 generation with two or more health issues.
The report found that nearly 30 million Americans have
atrazine in their tap water -- and that Texans who live near sorghum or corn-growing areas are more likely to have contaminated drinking water.
What is
atrazine and why is it harmful?Atrazine is a herbicide used in the past to kill weeds in agricultural crops.
Caffeine (98%, CAS 5808-2) and
atrazine (99%, CAS 1912-24-9) were purchased from Fluka Analytical (USA), whereas carbamazepine (99%, CAS 298-46-4) was obtained from Sigma-Aldrich (USA).
Regarding
atrazine + mesotrione, it was observed greater toxicity than or equal to 80% for all species of crotalaria and plants death at the highest dose (Figure 2a).
Treatments were randomly assigned with four replicates each across seven treatments (n = 28) including: control,
atrazine (200 [micro]g/L), metolachlor (100 [micro]g/L), carbaryl (100 [micro]g/L), chlorothalonil (100 [micro]g/L),
atrazine + metolachlor (200 [micro]g/L + 100 [micro]g/L), and carbaryl + chlorothalonil (100 [micro]g/L + 100 [micro]g/L).
In this process, about 100.0 mg of ALG/ESC and ALG/ESC-Ca[Cl.sub.2] were immersed in 0.2 mL of alcoholic solutions of
atrazine and diuron with the concentration of 5.[10.sup.-3] mol x [L.sup.-1] for 24 h at room temperature.
According to the
Atrazine Health and Safety Guide published by the World Health Organization (1990), cardiac toxicity was observed in dogs after long-term oral administration of
atrazine and studies on rats have shown that
atrazine and its metabolites bind effectively to red blood cells and to the tissues of some of the major organs.
For identification and quantitative determination of fipronil and
atrazine, a high-performance liquid chromatography HPLC (Varian, model 920-LC) operating with a diode array detector (DAD; [micro]=220nm) was used.
Suppression of JKT-1 cell proliferation by 24-h exposure to various doses of
atrazine. Values shown are the percent change in cell number compared with control (steroid-free medium containing DMSO) given as the mean [+ or -] SE of three independent experiments.
A and Kundu S., Effect of dose and time of
atrazine application on weeds in maize (Zea mays) under midhill conditions of North-western Himalayas.
Atrazine (ATR, CAS# 1912-24-9; 98% purity) was obtained from ChemServices (West Chester, PA).
