Polycyclic aromatic hydrocarbons (PAHs) belong to a group od chemicals responsible, to a great extent, for the contamination of the industrial and ambient air. A number of industrial processes such as coke production, coal tar processing, production of electric energy and certain rubber goods as well as metallurgy, especially aluminium metallurgy with its anodes made of coal tar pitch are the major sources of PAH emission. An attempt was made to determine PAH concentrations at selected workposts at an aluminium production plant. Breathing zone air samples were collected by individual dosimetry. Coal tar pitch volatiles were determined by a gravimetric method and individual PAHs by HPLC. The presence of naphtalene, fluorene, phenanthrene, anthracene, fluoranthene, pyrene, triphenylene, benzo/a/anthracene, chrysene, benzo/a/pyrene, benzo/b/fluorenthene, benzo/k/fluoranthene, benzo/a/pyrene, dibenzo/a,h/anthracene, benzo/g,h,i/perylene and indeno/1,2,3-c,d/pyrene was identified at all investigated workposts. The highest concentrations of benzo/a/pyrene and coal tar pitch volatiles were found at workposts of crane operators which is due to the character of the work performed. The replacement of "wet" anode material by the "dry" one should contribute to improving of the working conditions.
多环芳烃（PAHs）属于一类在很大程度上导致工业和环境空气污染的化学物质。许多工业过程，如焦炭生产、煤焦油加工、电能生产以及某些橡胶制品的生产，还有冶金行业，特别是使用煤焦油沥青制成阳极的铝冶金行业，都是多环芳烃排放的主要来源。我们尝试测定一家铝生产厂选定工作岗位处的多环芳烃浓度。通过个体剂量测定法采集呼吸带空气样本。用重量法测定煤焦油沥青挥发物，用高效液相色谱法测定单个多环芳烃。在所有调查的工作岗位均检测到萘、芴、菲、蒽、荧蒽、芘、三亚苯、苯并[a]蒽、屈、苯并[a]芘、苯并[b]荧蒽、苯并[k]荧蒽、苯并[a]芘、二苯并[a,h]蒽、苯并[g,h,i]苝和茚并[1,2,3-c,d]芘的存在。在起重机操作员的工作岗位发现苯并[a]芘和煤焦油沥青挥发物的浓度最高，这是由所执行工作的性质所致。用“干式”阳极材料替代“湿式”阳极材料应有助于改善工作条件。
