Description:A hazard evaluation and technical assistance survey of the Mississippi Authority for the Control of Fire Ants, Mirex Formulation Plant (SIC-2879), Prairie, Mississippi to determine possible hazardous exposure of workers to mirex (2385855) was conducted. Air samples, bulk samples and floor sweepings were analyzed for mirex and kepone (143500) content. In addition, employees were interviewed concerning their medical and occupational history. Breathing zone air concentration of mirex for the mixing operator was 7.5mg/m3. The area samples near the scale measured 15mg/m3 of mirex. Kepone, if present, was at concentrations too low to be measured. The facility has implemented a number of improvements since the survey, such as engineering controls, better housekeeping, and improved personal protective equipment. These changes have greatly reduced the exposure of employees to airborne mirex. There is insufficient human exposure, medical, and epidemiological data on mirex to state conclusively its adverse health effects on humans. With the present limited knowledge about mirex toxicity, the precise degree of health risk presented by this rather low exposure is unknown.
