Abstract

Aim: The aim of this study is to generate and investigate oral bioaccessibility based on the health risk of polycyclic aromatic hydrocarbon (PAHs) in fly ash from waste tyres and petroleum products in Rivers State, Nigeria. Study Design: Crude oil, crude oil asphalt, artisanal diesel, refined diesel, waste engine oil and waste tyres samples were collected and incinerated. The different fly ash samples were analyzed with GC-MS. Place and Duration of Study: Rivers State is a state that is rich in oil in the Niger Delta area of Nigeria. The State has been experiencing the release of soot into the environment for more than five (5) years now. This soot is noticeable to all residents of Port Harcourt and its environment with soot covering both indoor and outdoor objects such as clothes, cars, houses, floors, soil, water body, etc. The five (5) petroleum products and waste tyres samples were collected and incinerated for six (6) weeks (22nd of June to 7th of August 2021). Methodology: The petroleum products and waste tyres samples were collected and incinerated. The different fly ash samples were collected after combustion daily. The total and oral bioaccessible PAH concentrations were determined using GC-MS. The oral bioaccessibility of PAHs in the fly ash was evaluated using the physiologically-based extraction test method (PBET) to determine the bioaccessible concentrations of 16 priority US Environmental Protection Agency (USEPA) PAHs in fly ash samples. The results obtained for PAHs were used for health risk assessment. Results: A wider range of total PAH concentrations were observed in the six (6) fly ash samples from 49.71 to 926.62 mg/kg. The PAHs concentrations were significantly higher in higher molecular weight PAHs (with benzene of 4-5-6 rings) than lower molecular weight PAHs (benzene of 2-3 rings). Naphthalene, acenaphthylene, acenaphthene, and fluorene with 2-3 ring structures had the highest bioaccessible concentrations in both gastric and gastrointestinal phases of all the six fly ash samples studied. Flourene had the maximum percentage bioaccessibility of 91.30 % in the gastric phase from locally refined diesel fly ash whilst acenaphthene had a maximum percentage bioaccessibility of 98.75% in the gastrointestinal phase from crude oil asphalt fly ash. Conclusion: Data obtained from this study indicated that crude oil fly ash is a potential point source of toxic polycyclic aromatic hydrocarbons with significant levels of health risk to humans.
多环芳烃在石油产品和废轮胎焚烧产生的飞灰中的口服生物可及性
目的:本研究的目的是基于尼日利亚河流州废旧轮胎和石油产品飞灰中多环芳烃(PAHs)的健康风险来产生和调查口服生物可及性。研究设计:收集并焚烧原油、原油沥青、手工柴油、精炼柴油、废机油和废轮胎样品。采用气相色谱-质谱法对不同粉煤灰样品进行分析。学习地点和时间:河流州是尼日利亚尼日尔三角洲地区一个石油储量丰富的州。到目前为止,国家已经经历了五年多的煤烟排放到环境中。这种烟尘对哈科特港的所有居民及其环境都是明显的,烟尘覆盖了室内和室外的物体,如衣服、汽车、房屋、地板、土壤、水体等。收集五(5)个石油产品和废轮胎样本并焚烧六(6)周(2021年6月22日至8月7日)。方法:收集石油产品和废轮胎样品并焚烧处理。燃烧后每天采集不同的粉煤灰样品。采用气相色谱-质谱法测定总浓度和口服生物可及性多环芳烃浓度。采用生理提取法(PBET)测定了16种美国环保局(USEPA)重点规定的多环芳烃在粉煤灰样品中的生物可达性。多环芳烃的检测结果用于健康风险评估。结果:6份粉煤灰样品中多环芳烃总浓度范围在49.71 ~ 926.62 mg/kg之间。高分子量多环芳烃(含4-5-6环苯)的浓度显著高于低分子量多环芳烃(含2-3环苯)。六种粉煤灰样品中,萘、苊、苊和2-3环结构的芴在胃相和胃肠道相的生物可达性浓度最高。本地精炼柴油粉煤灰对芴在胃相的最大生物可及度为91.30%,原油沥青粉煤灰对苊在胃相的最大生物可及度为98.75%。结论:本研究数据表明,原油飞灰是有毒多环芳烃的潜在点源,对人类健康具有显著风险。
