Abstract

The present study determined the levels of sixteen polycyclic aromatic hydrocarbons (PAHs) in rice (Oryza Sativa) samples from six agricultural locations in Bade and Karasuwa Local Government Areas, Yobe State, Nigeria. Four varieties of rice (FARO 42, 44, 45 and 52) were collected for this study. The concentrations of PAHs in the study rice samples were lower than the maximum allowable concentration (MAC), average daily dose (ADD) of PAHs in the different variety of rice from the six agricultural locations shows that FARO 44 had the highest ADD (5.84 x1011 mg/kg), while FARO 52 shows the lowest ADD (1.20 x1015 mg/kg). The potential for non-carcinogenic PAHs in this study revealed that FARO 42 has the highest hazard index (2.04 x1011 mg/kg). Result from incremental lifetime expectancy cancer risk shows that FARO 44 from Jawa had the highest value (4.19 x1010 mg/kg), while the lowest value (7.61 x1015 mg/kg) was recorded for FARO 52 from Rina Kuna agricultural location. Results from the present study shows that the rice samples from the study locations are safe for human consumption and not significantly contaminated by PAHs.
尼日利亚约贝州不同品种水稻(Oryza sativa)中的多环芳烃
本研究确定了来自尼日利亚约贝州Bade和Karasuwa地方政府区的六个农业地点的水稻(Oryza Sativa)样品中16种多环芳烃(PAHs)的水平。本研究收集了4个水稻品种(FARO 42、44、45和52)。研究水稻样品中多环芳烃的浓度均低于最大允许浓度(MAC), 6个农业地点不同品种水稻中多环芳烃的平均日剂量(ADD)显示,FARO 44的ADD最高(5.84 × 1011 mg/kg), FARO 52的ADD最低(1.20 × 1015 mg/kg)。本研究非致癌性多环芳烃的潜在含量显示,FARO 42的危害指数最高(2.04 × 1011 mg/kg)。预期寿命癌症风险增量结果显示,爪哇地区的FARO 44最高(4.19 x1010 mg/kg),而里纳库纳地区的FARO 52最低(7.61 x1015 mg/kg)。本研究结果表明,研究地点的大米样品可供人类食用是安全的,没有明显的多环芳烃污染。
