  • Lifetime Organophosphorous Insecticide Use Among Private Pesticide Applicators in the Agricultural Health Study

All rights reserved 1559-0631/12 www.nature.com/jes ORIGINAL ARTICLE Lifetime organophosphorous insecticide use among private pesticide applicators in the Agricultural Health Study Jane A. Hoppin1, Stuart Long2, David M. Umbach3, Jay H. Lubin4, Sarah E. Starks5, Fred Gerr5, Kent Thomas6, Cynthia J. Hines7, Scott Weichenthal8, Freya Kamel1, Stella Koutros9, Michael Alavanja9, Laura E. Beane Freeman9 and Dale P. Sandler1 Organophosphorous insecticides (OPs) are the most commonly used insecticides in US agriculture, but little information is available regarding specific OP use by individual farmers. We describe OP use for licensed private pesticide applicators from Iowa and North Carolina in the Agricultural Health Study (AHS) using lifetime pesticide use data from 701 randomly selected male participants collected at three time periods. Of 27 OPs studied, 20 were used by 41%. Overall, 95% had ever applied at least one OP. The median number of different OPs used was 4 (maximum ¼ 13). Malathion was the most commonly used OP (74%) followed by chlorpyrifos (54%). OP use declined over time. At the first interview (1993--1997), 68% of participants had applied OPs in the past year; by the last interview (2005--2007), only 42% had. Similarly, median annual application days of OPs declined from 13.5 to 6 days. Although OP use was common, the specific OPs used varied by state, time period, and individual. Much of the variability in OP use was associated with the choice of OP, rather than the frequency or duration of application.

Their acute toxicity highlighted more than ever the need to explore applicable strategies for the sensing, decontamination and/or detoxifcation of these compounds. Herein, we report the use of two diferent thermostable enzyme families capable to detect and inactivate OPs. In particular, mutants of carboxylesterase-2 from Alicyclobacillus acidocaldarius and of phosphotriesterase-like lactonases from Sulfolobus solfataricus and Sulfolobus acidocaldarius, have been selected and assembled in an optimized format for the development of an electrochemical biosensor and a decontamination formulation, respectively. The features of the developed tools have been tested in an ad-hoc fabricated chamber, to mimic an alarming situation of exposure to a nerve agent. Choosing ethyl-paraoxon as nerve agent simulant, a limit of detection (LOD) of 0.4 nM, after 5 s of exposure time was obtained. Furthermore, an optimized enzymatic formulation was used for a fast and efcient environmental detoxifcation (>99%) of the nebulized nerve agent simulants in the air and on surfaces. Crucial, large- scale experiments have been possible thanks to production of grams amounts of pure (>90%) enzymes.

Despite their usefulness, these insecticides can pose a dangerous risk to the safety of food, environment and all living things through various mechanisms of action. Concern about the environmental impact of repeated use of insecticides has prompted many researchers to develop rapid, economical, uncomplicated and user-friendly analytical method for the detection of insecticides. In this regards, optical sensors are considered as favorable methods for insecticides analysis because of their special features including rapid detection time, low cost, easy to use and high selectivity and sensitivity. In this review, current progresses of incorporation between recognition elements and optical sensors for insecticide detection are discussed and evaluated well, by categorizing it based on insecticide chemical classes, including the range of detection and limit of detection. Additionally, this review aims to provide powerful insights to researchers for the future development of optical sensors in the detection of insecticides.

  • IARC Monographs Volume 112: Evaluation of Five Organophosphate Insecticides and Herbicides
    20 March 2015 IARC Monographs Volume 112: evaluation of five organophosphate insecticides and herbicides Lyon, France, 20 March 2015 – The International Agency for Research on Cancer (IARC), the specialized cancer agency of the World Health Organization, has assessed the carcinogenicity of five organophosphate pesticides. A summary of the final evaluations together with a short rationale have now been published online in The Lancet Oncology, and the detailed assessments will be published as Volume 112 of the IARC Monographs. What were the results of the IARC evaluations? The herbicide glyphosate and the insecticides malathion and diazinon were classified as probably carcinogenic to humans (Group 2A). The insecticides tetrachlorvinphos and parathion were classified as possibly carcinogenic to humans (Group 2B). What was the scientific basis of the IARC evaluations? The pesticides tetrachlorvinphos and parathion were classified as possibly carcinogenic to humans (Group 2B) based on convincing evidence that these agents cause cancer in laboratory animals. For the insecticide malathion, there is limited evidence of carcinogenicity in humans for non-Hodgkin lymphoma and prostate cancer. The evidence in humans is from studies of exposures, mostly agricultural, in the USA, Canada, and Sweden published since 2001. Malathion also caused tumours in rodent studies. Malathion caused DNA and chromosomal damage and also disrupted hormone pathways. For the insecticide diazinon, there was limited evidence of carcinogenicity in humans for non-Hodgkin lymphoma and lung cancer. The evidence in humans is from studies of agricultural exposures in the USA and Canada published since 2001. The classification of diazinon in Group 2A was also based on strong evidence that diazinon induced DNA or chromosomal damage.
