摘要: 露天焚烧是尼日利亚的一种常见的处置城市生活垃圾的方法。因此,环境空气中多环芳烃化合物的排放和燃烧产生的灰渣对环境造成了极大的危害。本文研究了城市生活垃圾露天焚烧对环境空气中多环芳烃含量和焚烧灰渣中多环芳烃含量的影响。在一个城市生活垃圾焚烧场的六个采样点采集了灰分样本。采用聚氨酯泡沫采样器采集了环境空气样品。在选定的离子监测模式下,使用气相色谱-质谱联用对多环芳烃进行定量分析。环境中多环芳烃浓度的变化趋势为:AS-A(4.023)>AS-B(3.798)>AS-D(3.468)>AS-C(3.288),灰分中多环芳烃的平均浓度为6.12 mg/kg。灰分样品中多环芳烃的浓度范围为5.69-6.34 mg/kg。主成分分析表明,环境中的多环芳烃主要来源于城市生活垃圾焚烧。政府和利益相关者应共同努力,保护环境和人类免受城市生活垃圾露天焚烧产生的多环芳烃的危害。

Abstract: Open burning of municipal solid waste (MSW) is a common practice in Nigeria. Emission of compounds of polycyclic aromatic hydrocarbon (PAHs) in ambient air and ash residues from burning of these wastes pose a great danger to the environment. This study investigated the contribution of open burning of MSW to the levels of PAHs in ambient air and ash residues from the burning site. Ash samples were obtained from six sampling locations at a MSW burning site. Polyurethane foam passive samplers were used in collecting ambient air samples. Quantification of PAHs was carried out using GC–MS operated in selected ion monitoring mode. The trend of ambient concentration of PAHs was; ∑ PAHs AS-A (4.023)>AS-B (3.798)>AS-D (3.468)>AS-C (3.288), while average concentration of PAHs in the ash was 6.12 mg/kg. Concentrations of PAHs in ash samples ranged from 5.69–6.34 mg/kg. Principal component analysis (PCA) showed that most of the PAHs in the ambient were from MSW combustion. The results obtained suggest that concerted effort of the government and the relevant stakeholders is required to safeguard the environment and humans from PAH pollution from open burning of MSW.
