Book excerpt: With three million intoxications a year, global concern about occupational exposure to pesticides makes it crucial that occupational health professionals be able monitor pesticide exposure. With a useful analysis of the advantages and disadvantages of classic and modern techniques, Occupational Hazards of Pesticide Exposure permits professionals to undertake these tasks with techniques best suited to a given situation. Includes descriptions and examples of how to: o Quantify aerial drift of pesticide sprays o Determine on-target/off-target loss of pesticide o Measure disposition of pesticides on surfaces o Detect translocation of residues for air and surfaces to skin o Measure absorption through the skin o Quantify residues or metabolites in biological fluids o Determine the extent of neurological impairment
Download or read book Spray Drift Deposits from Low Volume Application Using Oil and Water Carriers written by LE. Bode and published by . This book was released on 1987 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twelve direct drift comparisons were made from four atomizers using soybean oil and water as the spray carrier. Downwind drift deposits from the rotary atomizer and air-assist nozzles depended on operating conditions. The use of oil for application of chemicals provided little difference in drift reduction as compared to water. Oil has a nonevaporative character compared to water and so deposited higher amounts and drifted further downwind. With conventional twin-orifice and flat fan nozzles oil drifted further downwind than water. Comparing nozzle types, low volume applicators showed more downwind drift than conventional nozzles.
Download or read book Spray Drift and Deposit Pattern from a Forest Herbicide Application written by and published by . This book was released on 1991 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: In October 1989, a series of trials were carried out at Ruby Creek, British Columbia to compare the air sampling capability of a number of drift measuring devices in a forest pesticide spraying with a helicopter. Since this study was not designed for a mass balance, no attempt was made to fully bracket or define the drifting cloud, neither vertically nor horizontally. Because of the need for total accountability of the emitted material, the study was extended into a preliminary mass balance evaluation. This report presents the results of the mass balance evaluation, calculated using Kromekote card and Petri dish deposit samplers and two air samplers.
Download or read book Multiple Metal Cations as Spray Deposit Tracers and Evaluation of the AGDISP Ground Boom Spray Drift Model written by J. A. Zabkiewicz and published by . This book was released on 2009 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The determination of spray drift by agrichemicals in field applications is laborious and expensive. Dyes have been used as tracers to reduce workloads and costs, but these methods have technical drawbacks. Metal cations have also been used as tracers and this method is promising, especially if a number of distinct cations from consecutive spray applications can be collected cumulatively by the same collectors. This study evaluated the use of various water soluble metal cation salts and plastic tape as a cost-effective collector for spray drift deposits. Measured deposit values were compared with calculated outputs from the AGDISP ground boom spray drift model. The comparisons showed that AGDISP over estimated downwind deposition and under estimated deposition within the last swathe in the spray block. Increasing boom height above the canopy improved within spray block deposition estimates. Varying wind direction had negligible effect; increasing relative humidity gave greater deposition closer to the spray block. These trends are discussed, together with the pros and cons of the metal cation and plastic tape collector system.
Download or read book Forestry Pesticide Aerial Spraying written by J.J. Picot and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduced to the technical aspects of forestry aerial spraying in the mid-1970's, we were immediately impressed by the complexity of the process of delivering pesticide to foliage. At that time, there was a vigorous public debate in New Brunswick about the ecological and public h~alth impacts of the annual spray program for the control of defoliation of spruce and fir trees by the spruce budworm. The forest industry is important to the province and changes to the established procedures of budworm control could have major economic implications. A rational debate required reliable information about the mechanics of the spraying process. There was a need to supply missing information as to required pesticide application rates, atomizer performance, off-target drift and deposit, and the effects of weather and aircraft operating factors. We were invited to initiate a research program in this domain by New Brunswick forest management officials, and what follows in this book is a logical and quantitative description of the overall process based on our own research and that of others over the intervening years. After a short introduction to aerial spraying, we begin (Chapter 2) by describing forest stands in terms of their interaction with suspended atmospheric particulate material carried along by the wind and susceptible to deposition on foliage. We introduce foliage simulators and their use in measuring the deposit of sprayed pesticide on foliage, the "biological interface" between pest and pesticide.

Available in PDF, EPUB and Kindle. Book excerpt: Integrated Pest Management is an effective and environmentally sensitive approach that relies on a combination of common-sense practices. Its programs use current and comprehensive information on the life cycles of pests and their interactions with the environment. This information, in combination with available pest control methods, is used to manage pest damage by the most economical means and with the least possible hazard to people, property, and the environment.
Download or read book Quantification of Spray Drift from Aerial Applications of Pesticide written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: With widespread use of pesticides in modern agriculture, the impacts of spray drift have become a topic of considerable interest. The drifting of sprays is a highly complex process influenced by many factors. Advances in aerial application technology and in our ability to measure drift, coupled with the adoption of new technologies for regulating pesticide application have necessitated further research in the pesticide application process. Experiments were conducted to quantify spray drift and describe its movement from aerial applications of pesticide. The effects of spray quality, atomizer type and ground cover were examined. Initial airborne drift amounts were greater than downwind deposits, thus not all of the drifting spray was deposited in the measuring area. Total off-target movement of spray was significantly greater for Fine compared to Coarse sprays. Rotary and hydraulic atomizers, both producing Fine sprays, produced statistically similar off-target movement of sprays. Similarly, no significant statistical differences in spray drift between applications to bare ground and applications to a headed barley crop canopy were not identified. Contrary to expectations, aerial application to bare ground seemed to result in less off-target movement than application to a crop canopy. The vertical spray cloud profiles were similar for all applications with the greatest amount of spray present at the height of release. Spray concentrations diminished from that height upward with diffusion and downward with deposition. The empirical data disagreed with the mechanistic model AgDISP which is currently used in the Canadian regulatory process. The model over-predicted drift deposition by a factor of two to five. Variability in spray deposit values could not be attributed to average differences in meteorological conditions at the time of application. Experiments with appropriate protocols for increased sensitivity may be required to more accurately report subtle differences.
