In-Depth Survey Report: Control Technology for a Dry Chemical Bagging and Filling Operation at Monsanto (Monsanto Agricultural Products Co.), Muscatine, Iowa

摘要

Exposure to agricultural herbicides at the Monsanto Agricultural Products Company (SIC-2879, SIC-2869, SIC-2819), Muscatine, Iowa, was investigated. The evaluation of atmospheric dust concentrations, ventilation control systems, and other dust control techniques was limited to the bagging operation in the processing and storage building. With improved controls, it may be possible to use a similar system to maintain the lower threshold limit values required for more toxic herbicides.
