Currently very little data exists on the presence of persistent organic pollutants (POPs) and polycyclic aromatic hydrocarbons (PAHs) in the South African environment. To address this data gap a preliminary study of a highly industrialised area of South Africa, the Vaal Triangle, was done. Soil and sediment samples from the Vaal Triangle, as well as other areas in central South Africa, were analysed with high resolution gas chromatography-high resolution mass spectrometry (HRGC/HRMS) for the presence of PAHs, polychlorinated biphenyls (PCBs), dioxin-like chemicals and organochlorine pesticides (OCPs). Results showed that these chemicals are present in the South African environment with concentrations ranging between 39,000 ng g(-1) for SigmaPAHs and 0.01 ng g(-1) for dicofol. Principal component analysis (PCA) indicated different pollution sources in industrial and agricultural areas.
目前，关于南非环境中持久性有机污染物（POPs）和多环芳烃（PAHs）的存在情况，现有数据非常少。为填补这一数据空白，对南非一个高度工业化的地区——瓦尔三角区进行了初步研究。采用高分辨率气相色谱 - 高分辨率质谱法（HRGC/HRMS）对来自瓦尔三角区以及南非中部其他地区的土壤和沉积物样本进行分析，以检测其中多环芳烃、多氯联苯（PCBs）、类二噁英化学物质和有机氯农药（OCPs）的存在情况。结果表明，这些化学物质存在于南非环境中，其浓度范围为：总多环芳烃（ΣPAHs）为39,000 ng g⁻¹，三氯杀螨醇为0.01 ng g⁻¹。主成分分析（PCA）表明，工业和农业地区存在不同污染来源。
