A mathematical model is used to predict relative body burdens of inhaled contaminants in workers who work two jobs or overtime, or who experience off-the-job exposure to air contaminants. Expected "peak" or maximum body burdens from multiple exposures are compared to those expected from the "normal" occupational exposure on which TLVs and Permissible Exposure Limits (PELs) arebased (five 8-hour days per week with zero off-the-job exposure). The model is designed to predict what adjustments to the TLVs and PELs are necessary to avoid accumulation of excess peak body burdens of contaminants from the additional exposures incurred. The general application of models to determine occupational exposure limits is reviewed, and several models are compared.
一个数学模型用于预测从事两份工作或加班的工人，或在工作之余接触空气污染物的工人吸入污染物的相对身体负担。将多次接触预期的“峰值”或最大身体负担与基于阈限值（TLV）和许可接触限值（PEL）的“正常”职业接触预期的负担进行比较（每周五天，每天8小时，工作之余无接触）。该模型旨在预测需要对TLV和PEL进行哪些调整，以避免因额外接触而导致污染物峰值身体负担的过度累积。本文回顾了用于确定职业接触限值的模型的一般应用，并比较了几种模型。
