Three commercially available backpack sprayers were evaluated with Aqualuer® 20-20 (20.6% permethrin, active ingredient; 20.6% piperonyl butoxide, technical) against caged adult Aedes aegypti in semifield trials in northeastern Florida. Two battery-powered sprayers, Birchmeier and Hudson, were compared with the standard hand-pump SOLO 425 sprayer, which is currently used in pest management oper...

BACKGROUND We assessed the cancer risks of four different Finnish asbestos-exposed cohorts. We also explored if the cohorts with varying profiles of asbestos exposure exhibited varying relative risks of cancer. METHODS The incident cancer cases for the asbestos-exposed worker cohorts were updated to the end of 2012 using the files of the Finnish Cancer Registry. The previously formed cohorts ...

Just as houses are made of stones, so is science made of facts. But a pile of stones is not a house, and a collection of facts is not necessarily science. Bugged by Automatic Sprayers Automatic insecticide dispensers are designed to keep restaurants, schools, and other public settings free from annoying and unsanitary flying insects. They may also do something else: sicken at least some of the ...

Plant protection and the application of mineral fertilizers play an important role in production agricultural products. To improve technological processes develop new models self-propelled rod sprayers, it is advisable to determine laws distribution their technical parameters. A number power installed engines sprayers has a coefficient variation 30.4%, which indicates that close normal. For 95%...

BACKGROUND Diverse group of agro-chemicals are indiscriminately sprayed by the farmers for pest control to enhance crop yield. About 25 million agricultural workers in the developing world suffer from at least one episode of poisoning each year, mainly by anticholinesterase- like organophosphates (OPs). OBJECTIVE The present study was aimed to establish the OP toxicity in 187 occupationally e...

OBJECTIVES To develop a method for the measurement of a metabolite of hexamethylene diisocyanate (HDI), an isocyanate, and use it to assess the exposure of sprayers employed in motor vehicle repair shops. METHODS Urine samples were taken from sprayers wearing personal protective equipment and spraying in booths or with local exhaust ventilation, from bystanders, and from unexposed subjects. S...

AIMS To evaluate effects of exposure to bisphenol A diglycidyl ether (BADGE) on urinary excretion of bisphenol A, and plasma gonadotrophic hormones and testosterone in male epoxy resin sprayers. METHODS Cross sectional study of 42 workers whose job was to spray epoxy resin hardening agents including BADGE and mixed organic solvents, and 42 matched control workers without BADGE use in the same...

Several tests were performed on commercially used orchard sprayers with different types of air discharge systems (conventional, cross flow, directional spouts). The measurements were conducted in a hangar on an apple orchard planted in containers. Pure tab water and water with minerals (Mg, Mn, Zn) were sprayed. Water sensitive paper and blotting paper were put in and around the trees to evalua...
