The half-time persistence of atrazine in soils is usually about 4 days, but may range up to 385 days in dry, sandy, alkaline soils, under conditions of low temperature and low microbial densities. (unl.edu)
atrazine annually have many, soils that have never received atrazine have very few such bacteria , and soils that have received atrazine intermittently have an intermediate number. (floralibrary.com)
In the soils studied, the extrapolated half-lives varied from 88 to 116 days for terbuthylazine and 66 to 105 days for atrazine, with no signiÐcant di †erences for the three soils and the two molecules. (univ-lorraine.fr)

Atrazine (ATZ) is an environmental pollutant that interferes with several aspects of mammalian cellular processes including germ cell development, immunological, reproductive and neurological functions. (frontiersin.org)

The EPA recently published their Preliminary Interim Decision (PID) on atrazine. (ilcorn.org)
The Iowa Farm Bureau Federation (IFBF), the largest general farm organization in the state with more than 153,000 members, appreciates the opportunity to file these comments on the Environmental Protection Agency's Proposed Interim Decision (PID) for atrazine and the other triazines .

Atrazine degradation by bioaugmented sediment from constructed wetlands. (oregonstate.edu)

Atrazine was invented in 1958 in the Geigy laboratories as the second of a series of 1,3,5-triazines. (wikipedia.org)

Scientist Tyrone Hayes reels off the list of effects on amphibians, rats and humans that he and other researchers have linked to the chemical atrazine. (eugeneweekly.com)

He says the study shows atrazine interrupts the endocrine system and mutates human hormones. (mprnews.org)
Lindsay does acknowledge that studies have shown atrazine has caused abnormalities in the endocrine systems of lab rats. (mprnews.org)

The population density of atrazine-degrading microorganisms in unbioaugmented sediment was increased from approximately 10(2)/g to 10(4)/g by bioaugmentation (1:100 w/w), and increased by another 60-fold (6.0x10(5) g(-1)) after incubation with 10 microg g(-1) of atrazine. (oregonstate.edu)
A high population of atrazine degraders (approximately 10(6) g(-1)) and enhanced rates of atrazine mineralization also developed in bioaugmented sediment after incubation in flooded mesocosms planted with cattails (Typha latifolia) and supplemented with atrazine (3.2 mg l(-1), 1 microg g(-1) sediment). (oregonstate.edu)
The impact of different atrazine concentration on a chitinolytic actinomycete and the biodegradation of atrazine by this microbe was examined.Isolates were grown in pure culture in Chitin Mineral Salts Broth with and without addition of atrazine for a two month incubation at room temperature on a rotary shaker. (bsu.edu)

Atrazine does not accumulate in living organisms such as algae, bacteria, clams, or fish. (cdc.gov)

resulted in decreased fetal body weight, Atrazine is the most widely used through ingestion of contaminated well Inhalation incomplete ossification, herbicide in the United States. (cdc.gov)

Available information is inadequate to definitely state whether atrazine causes cancer in humans. (cdc.gov)
A Cancer Assessment Review Committee (CARC) sponsored by EPA has classified atrazine as not likely to be carcinogenic to humans. (cdc.gov)
The International Agency for Research on Cancer (IARC) has determined that atrazine is not classifiable as to its carcinogenicity to humans. (cdc.gov)
Once absorbed by humans, atrazine is to buy or use. (cdc.gov)
That study is looking at whether atrazine has caused any diseases in humans. (mprnews.org)

The USDA's National Agricultural Statistics Service estimates the actual atrazine use rate in Iowa is 1.037 pounds per acre per year. (iowafarmbureau.com)
The maximum labeled rate for atrazine in most application situations in Iowa is 2 pounds per acre. (iowafarmbureau.com)

Never spray atrazine on windy days because it will drift onto other plants. (ehow.com)

Hayes' work allows state and federal agencies to better understand the possible effects on human health by chemicals such as atrazine. (eugeneweekly.com)

Atrazine has been found to act as an agonist of the G protein-coupled estrogen receptor 1. (wikipedia.org)

Title : Two-dimensional high performance liquid chromatography separation and tandem mass spectrometry detection of atrazine and its metabolic and hydrolysis products in urine☆ Personal Author(s) : Kuklenyik, Zsuzsanna;Panuwet, Parinya;Jayatilaka, Nayana K.;Pirkle, James L.;Calafat, Antonia M. (cdc.gov)
Electrochemically co-polymerised folic acid and riboflavin as well as folic acid and L-lysine were employed for the detection of atrazine using square wave voltammetry. (lmaleidykla.lt)
The best method was the square wave voltammetry showing the best sensitivity to atrazine 198 ± 1 μA/μM cm2, and the limit of detection was 14.8 nM. (lmaleidykla.lt)

Regression analyses indicated that May through June precipitation and hectares enrolled in the EQIP pest management practice (Natural Resource Conservation Service Practice 595) were the two most important predictors of reservoir atrazine concentration. (jswconline.org)
Only the 0.1 ppm atrazine concentration with the actinomycete culture demonstrated tolerance to the atrazine and showed chitinolytic activity in the radioactive assay and chitin derivatives by HPLC. (bsu.edu)

Analysis by HPLC and Gas Chromatography with Electron Capture Detector (GC with ECD) were used to determine the breakdown of atrazine.No atrazine derivatives were determined by HPLC and GC analysis. (bsu.edu)

Farm workers, chemical sprayers, and people who work in factories that make atrazine may be exposed. (cdc.gov)
Of these inaccurate and misleading statements, 96.5% seem to benefit the makers of atrazine in that they support the safety of the chemical. (panna.org)
Chemical analyses for atrazine are complicated, expensive and can be made only in specialized laboratories. (onvegetables.com)
Atrazine residue may decrease due to chemical and biological breakdown if samples are stored indoors under warm conditions. (onvegetables.com)

Now the agency is accepting comments on a new petition to pull the use of atrazine, a petition that points to misleading industry-funded science as the basis for keeping this widely used herbicide on the market. (panna.org)
