Environmental and breathing zone samples were analyzed for phosphine (12768820), malathion (121755), carbon-disulfide (75150), carbon- tetrachloride (56235), and grain dust at field offices of the Federal Grain Inspection Service (SIC-4782), United States Department of Agriculture, New Orleans, Louisiana in October and November, 1984. The evaluation was requested by the inspection service to investigate fumigant exposures at grain sampling and inspection stations in the New Orleans area. Noise monitoring was also performed. Carbon-tetrachloride was the only fumigant detected, concentrations ranging from 1.0 to 1.7 milligrams per cubic meter (mg/m3). The OSHA standard for carbon-tetrachloride is 10mg/m3. Grain dust concentrations ranged from 0.1 to 2.7mg/m3. The American Conference of Governmental Industrial Hygienists threshold limit value for grain dust is 4mg/m3. All measured noise levels were below 82 A-weighted decibels (dBA). The OSHA standard for noise is 90dBA. The author concludes that a health hazard due to fumigants, grain dust, or noise does not exist at the stations. Recommendations include developing a registry of grain handlers and inspectors and establishing procedures for obtaining information on incoming grain shipments that have been fumigated.
