Abstract The BEI® committee developed BEIs to equip Occupational and Environmental Health and Safety professionals to effectively integrate biomonitoring into exposure assessment programs. Biological monitoring is the measure of an exposure biomarker in breath, urine, or blood samples, and reflects total chemical uptake. Most BEI® are derived from TLV–TWA, aligning BEI determinant concentration with absorbed amounts at TLV–TWA airborne exposure. Certain BEI® (e.g., lead, CO) prevent adverse health effects directly, while others use population-based values (POPs), especially valuable for carcinogens under ALARA principles. Before setting up a biological monitoring program, why, who, and what to sample need to be determined. The BEI® documentation details how, when, and where to sample, along with transport, storage, analysis, and reporting. The when and why of biological monitoring hinge on diverse occupational exposure routes, recognizing skin absorption and non-occupational factors. Biological monitoring complements air sampling by including all routes of exposure (inhalation, skin absorption, and non-occupational exposures) and in most cases, reflect work-related factors, often adjustable to reduce exposure or implement workplace changes. The ultimate goal is to prevent adverse health effects, ensuring a safe workplace for all.

Abstract It is important that a hygienic standard is not open to widely different interpretations. This paper discusses the errors and standardization of the impinger dust count and recommends where, when, and how many impinger samples to take when testing compliance with the ACGIH threshold limit values for respirable dusts evaluated by count. The term “breathing zone” should be defined; for example, we may specify that the impinger should be located upstream and within 2 feet of the worker's nose and mouth. The samples should be spread throughout a shift or complete cycle of operations. The optimum sampling schedule is 32 samples each 15 minutes in duration. Factors are developed to enable the results to be compared with the TLV when, as is usual, the sampling schedule falls short of this optimum requirement. Present methods used for determining silica in the dust appear to be adequate for the purpose, at least for dusts with high silica content.
