Popis: This chapter reviews the literature on occupational exposure to pesticides with respect to relevant exposure data for enclosed environments, including greenhouse and mushroom houses. Such data are important for the evaluation of the labor conditions in specific greenhouses for specific crops, as well as for registration of pesticides. Potential exposure is determined by the chemical and physical properties of the pesticide, the physical parameters related to the type of crop, and the nature of the operations of the worker. For dermal exposure, the actual exposure to the skin is determined by the degree of penetration of the clothing. For inhalation, the actual exposure is determined by the degree of inspiration of the particles involved and by interception of respiratory protective equipment as a function of the potential exposure. For oral exposure, no measures are yet available. The most elaborate method for the determination of the absorbed dose is biological monitoring. The method requires a basic knowledge of the pharmacokinetics of the active ingredient and is, therefore, compound-specific. Re-entry exposure is determined by the pesticide concentration available in the surroundings of the worker. This includes the amount still present in air as vapor and/or aerosols or available by evaporation from crop, soil, objects, or materials present, or the amount brought into the air by the workers' activities and the degree of contact of the worker with contaminated surfaces.
