Catch the drift. Assessing risk from pesticide spraying.
نویسنده
چکیده
Sins of the Father ParentalSmoking and Childhood Cancer Exposure to passive (or environmental) tobacco smoke has been implicated in numerous childhood ailments ranging from low birth weight to middle ear disease. Passive smoke has also been suspected, but not proven, to increase the risk of childhood cancer. Clarifying this issue is crucial not only for the protection of children's health but also for the fashioning of policy concerning smoking in public and private facilities. In this month's issue, Paolo Boffetta and colleagues present their meta-analysis of the results of more than 30 studies on the association between exposure to tobacco smoke from parental smoking during pregnancy and cancer in childhood [EHP 108:73-82]. The biological plausibility of the association between passive tobacco smoke and childhood cancer is based on studies that show that children do take in tobacco components-including carcinogens and mutagens-when exposed to tobacco smoke during both gestation and childhood. Activation of procarcinogens in human fetal and placental tissues has been demonstrated, as has smokeinduced damage to DNA in human placenta. In conducting their meta-analysis, the authors searched the medical literature for epidemiological studies on childhood cancer where

Reducing Spray Drift
Spray drift is the movement of a pesticide through the air, during or after application, to a site other than the intended target. Drift is considered to be the most challenging problem facing applicators and pesticide manufacturers. Although drift may occur as vaporized active pesticide from the application site, it is usually the physical movement of very small drops from the target area at t...

متن کاملThe Cutting Edge
“The bigger they are, the harder they fall” is a bit of wisdom that’s been around for a long time. But when it comes to pesticide application, the line should read, “The bigger they are, the closer they fall.” Large droplets are not as likely to drift off-target as smaller droplets. This basic principle lies behind many innovations to reduce drift when spraying herbicides. Nozzle manufacturers ...

متن کاملDoes an association between pesticide use and subsequent declines in catch of Atlantic salmon (Salmo salar) represent a case of endocrine disruption?
Historical aerial applications of the insecticide Matacil 1.8D provide an opportunity to look for potential effects of the endocrine disrupting compound 4-nonylphenol (4-NP) on Atlantic salmon (Salmo salar) populations. Matacil 1.8D contained the carbamate insecticide aminocarb, with 4-NP as primary solvent. Between 1975 and 1985 Matacil 1.8D was applied to forests in Atlantic Canada to control...
