2、本。凡是不注日期的引用文件，其最新版本适用于本部分。GBZ 1 工业企业设计卫生标准GBZ 159 工作场所空气中有害物质监测的采样规范GBZ 160 工作场所空气有毒物质测定3 术语和定义下列术语和定义适用于本标准：3.1 职业接触限值 occupational exposure limits，OELs职业性有害因素的接触限制量值。指劳动者在职业活动过程中长期反复接触，对绝大多数接触者的健康不引起有害作用的容许接触水平。化学有害因素的职业接触限值包括时间加权平均容许浓度、短时间接触容许浓度和最高容许浓度三类。3.1.1 时间加权平均容许浓度 permissible concentration

3、-time weighted average，PC-TWA以时间为权数规定的8h工作日、40h工作周的平均容许接触浓度。3.1.2 短时间接触容许浓度 permissible concentration-short term exposure limit，PC-STEL在遵守PC-TWA前提下容许短时间（15min）接触的浓度。3.1.3 最高容许浓度 maximum allowable concentration，MAC工作地点、在一个工作日内、任何时间有毒化学物质均不应超过的浓度。3.2 超限倍数 excursion limits对未制定PC-STEL的化学有害因素，在符合8h时间加权平均

4、容许浓度的情况下，任何一次短时间（15min）接触的浓度均不应超过的PC-TWA的倍数值。3.3 工作场所 workplace劳动者进行职业活动的所有地点。3.4 工作地点 work site劳动者从事职业活动或进行生产管理而经常或定时停留的岗位作业地点。3.5 化学有害因素 chemical hazards本标准所指化学有害因素除包括化学物质、粉尘外，还包括生物因素。3.6 总粉尘 total dust可进入整个呼吸道（鼻、咽和喉、胸腔支气管、细支气管和肺泡）的粉尘，简称总尘。技术上系用总粉尘采样器按标准方法在呼吸带测得的所有粉尘。3.7 空气动力学直径 aerodynamic diamet

5、er，dae某颗粒物（任何形状和密度）与相对密度为的球体在静止或层流空气中若沉降速率相等，则球体的直径视作该颗粒物的空气动力学直径。3.8 呼吸性粉尘 respirable dust按呼吸性粉尘标准测定方法所采集的可进入肺泡的粉尘粒子，其空气动力学直径均在7.07µm以下，空气动力学直径5µm粉尘粒子的采样效率为50%，简称“呼尘”。4 卫生要求4.1 工作场所空气中化学物质容许浓度工作场所空气中化学物质容许浓度见表1。表1 工作场所空气中化学物质容许浓度序号中文名英文名化学文摘号(CAS No.)OELs（mg/m3）备注MACPC-TWAPC-STEL1安妥Antu86
