有关非洲环境介质中多氯联苯 (PCB) 的信息有限。本文介绍了在南非夸祖鲁-纳塔尔省开展的一项监测计划的结果，该计划旨在描述空气中多氯联苯的水平、趋势和来源。 2004 年至 2005 年期间在三个地点采集了颗粒物和蒸气样本。 PCB 总浓度平均为 128 ± 47 pg m−3，冬季浓度最高。三元至六元同系物占主导地位，且蒸气馏分占主导地位。几种四至六氯化同源物的水平与北半球城市地点的水平相当，但七至十氯化同源物的水平与背景地点的水平相似。利用空间和时间模式、成分信息和轨迹分析推断出的多氯联苯来源区域可能包括本地、区域和全球来源。三个农村地点的土壤显示出较高的 PCB 浓度，当地一家乳品厂的牛奶显示出的 PCB 浓度与美国 2000 年的水平相当。
Information regarding polychlorinated biphenyls (PCBs) in environmental media in Africa is limited. This paper presents results of a monitoring program conducted in KwaZulu-Natal Province, South Africa designed to characterize levels, trends and sources of airborne PCBs. Particulate and vapor samples were sampled over the 2004–2005 period at three sites. The total PCB concentration averaged 128 ± 47 pg m−3, and levels were highest in winter. Tri- through hexa-congeners predominated, and the vapor fraction was predominant. Several tetra- through hexa-chlorinated congeners had levels comparable to those at urban sites in the northern hemisphere, but hepta- through deca-congeners resembled levels at background sites. PCB source areas, deduced using spatial and temporal patterns, compositional information and trajectory analyses, likely included local, regional and global sources. Soils at three rural sites showed high PCB concentrations, and milk from a local dairy showed PCB concentrations comparable to USA levels in year 2000.
