[Ambient air pollution with flour dust at the sites of baking and macaroni enterprises].

Ambient air pollution with flour dust (FD) and microorganisms, including microscopic fungi, was studied; the single concentrations of FD under emission plumes were 0.12-0.17 mg/m3; the total content of mould, field, and storage fungi was 700 +/- 30, 671 +/- 19, and 29 +/- 3, respectively. The maximum allowable concentrations for FD were ascertained; the equal ones were the maximum single concentration of 1.0; the daily average concentration was 0.4 mg/m3; hazard class IV; the limiting hazard index was their resorptive activity.
