摘要

奥韦里市的垃圾场释放出大量微粒,后来扩散到环境中的其他地区,对居民的健康造成不利挑战。为了分析PM浓度,在Owerri大都市的七个主要垃圾场进行了现场测量。利用美国环境保护局人体健康风险评估框架,对暴露于空气中颗粒物(PM2.5、PM10等)可能造成的健康风险进行了估计。一种情景评估方法,其中对婴儿、儿童和成人的急性和慢性暴露期采用正常暴露和最坏情况。垃圾场的pm2.5浓度为122.30 ~ 501.76 μg/m3,超过了世卫组织规定的24小时年平均最大暴露限值。大多数垃圾场的可吸入颗粒物超过了尼日利亚国家环境空气质量标准的允许限值。几乎所有垃圾场的pm2.5危害系数都超过了1,可能会对健康造成挑战。结果表明,在月度条件下,垃圾场的PM2.5和PM10浓度水平对婴幼儿、儿童和成人的急性或慢性健康都有可能造成不良影响。应采取行动规范这种PM暴露,并提高受影响地区居民的公众意识。因此,需要定期监测以降低研究区域的环境颗粒物(PM)浓度。

Particulate matter exposure and non-cancerous inhalation health risk assessment of major dumpsites of Oerri metropolis, Nigeria.

Numerous particulates are released from the dumpsites in Owerri metropolis and later dispersed to other areas in the environment where they cause adverse health challenges to the inhabitants. To analyze the PM concentration, field measurements were carried out at seven major dumpsites in the Owerri Metropolis. Estimates of the possible health risks as the result of exposure to airborne particulate matter (PM2.5, PM10, etc.) were performed using the US Environmental Protection Agency human health risk assessment framework. A scenario assessment approach in which normal exposure and worst-case scenario were adopted for acute and chronic exposure periods for infants, children, and adults. The concentrations of PM 2.5 which ranged from 122.30-501.76 μg/m3 at the dumpsites exceeded the WHO 24hr annual mean maximum exposure limit. The Nigerian National Ambient Air Quality Standard allowable limit for PM10 was exceeded by most of the dumpsites. Hazard quotient > 1 was exceeded for PM 2.5 by nearly all dumpsites and is likely to cause health challenges. The results showed that under monthly conditions, both PM2.5 and PM10 concentration levels at the dumpsites have the potential to cause adverse health effects when for infants, children, and adults on acute or chronic bases. Actions should be taken to regulate such PM exposure and to raise public awareness for the inhabitants of the affected areas. In conclusion, regular monitoring is therefore needed to decrease the ambient particulate matter (PM) concentrations in the study area.
