Humoral and cellular immunity rates in chemical plant workers producing dust pesticides.

Background: Exposure to pesticides may affect humoral and cell-mediated immunity.

Material And Methods: The study group was composed of 24 men employed in the production of dust pesticides and 23 females performing ancillary jobs under conditions of lower pesticide exposure. Chronic bronchitis was diagnosed in 10 males (41.

Humoral and cellular immunity rates in chemical plant workers employed in the production of liquid pesticides.

In order to assess the immunological system of the chemical plant workers certain rates of cellular and humoral immunity were estimated. The study group was composed of 19 males employed in the production of liquid pesticides, and 18 females performing ancillary jobs and handling closed containers. They were alternatively exposed to phosphoroorganic compounds and pyrethroides, and to chlorinated hydrocarbons, carbamates, nitrophenols and organic solvents, however exposure to the latter was lower.
