It is the most widely used herbicide in the world, and the third most commonly used in North America.[1] 2,4-D is also an important synthetic auxin, often used in laboratories for plant research and as a supplement in plant cell culture media such as MS medium. History 2,4-D was developed during World War II by a British team at Rothamsted Experimental Station, under the leadership of Judah Hirsch Quastel, aiming to increase crop yields for a nation at war.[citation needed] When it was commercially released in 1946, it became the first successful selective herbicide and allowed for greatly enhanced weed control in wheat, maize (corn), rice, and similar cereal grass crop, because it only kills dicots, leaving behind monocots. Mechanism of herbicide action 2,4-D is a synthetic auxin, which is a class of plant growth regulators.

Exposure to Herbicides in House Dust and Risk of Childhood Acute Lymphoblastic Leukemia
Journal of Exposure Science and Environmental Epidemiology (2013) 23, 363–370 & 2013 Nature America, Inc. All rights reserved 1559-0631/13 www.nature.com/jes ORIGINAL ARTICLE Exposure to herbicides in house dust and risk of childhood acute lymphoblastic leukemia Catherine Metayer1, Joanne S. Colt2, Patricia A. Buffler1, Helen D. Reed3, Steve Selvin1, Vonda Crouse4 and Mary H. Ward2 We examine the association between exposure to herbicides and childhood acute lymphoblastic leukemia (ALL). Dust samples were collected from homes of 269 ALL cases and 333 healthy controls (o8 years of age at diagnosis/reference date and residing in same home since diagnosis/reference date) in California, using a high-volume surface sampler or household vacuum bags. Amounts of agricultural or professional herbicides (alachlor, metolachlor, bromoxynil, bromoxynil octanoate, pebulate, butylate, prometryn, simazine, ethalfluralin, and pendimethalin) and residential herbicides (cyanazine, trifluralin, 2-methyl-4- chlorophenoxyacetic acid (MCPA), mecoprop, 2,4-dichlorophenoxyacetic acid (2,4-D), chlorthal, and dicamba) were measured. Odds ratios (OR) and 95% confidence intervals (CI) were estimated by logistic regression. Models included the herbicide of interest, age, sex, race/ethnicity, household income, year and season of dust sampling, neighborhood type, and residence type. The risk of childhood ALL was associated with dust levels of chlorthal; compared to homes with no detections, ORs for the first, second, and third tertiles were 1.49 (95% CI: 0.82–2.72), 1.49 (95% CI: 0.83–2.67), and 1.57 (95% CI: 0.90–2.73), respectively (P-value for linear trend ¼ 0.05). The magnitude of this association appeared to be higher in the presence of alachlor.

As indicated in Table 1, the correct value, from Knuteson (1999), is 49,000 mg/L. This error was noted by Dr. K. King (U.S. Fish and Wildlife Service). The error has been corrected. While the Gleams-Driver runs were made using the 100 mg/L water solubility, re-runs using the water solubility of 49,000 mg/L yielded results that are indistinguishable from the original runs. Thus, the appendices have not been change. Water solubility is not a sensitive parameter in GLEAMS unless the soil water is saturated. This did not occur in the Gleams-Driver modeling. July 9, 2016 During an audit of WorksheetMaker (Version 6.00.15), it was noted that the chronic toxicity values of TCP to aquatic invertebrates had been entered incorrectly into the WorksheetMaker database and the aquatic toxicity values of TCP for algae had been omitted.

As part of this program, the BLM is proposing the use of ten herbicide active ingredients (a.i.) to control invasive plants and noxious weeds on approximately one million of the 6 million acres proposed for treatment. The BLM and its contractor, ENSR, are preparing a Vegetation Treatments Programmatic Environmental Impact Statement (EIS) to evaluate this and other proposed vegetation treatment methods and alternatives on lands managed by the BLM in the western continental US and Alaska.
