Abstract

This paper presents data obtained from concurrently deployed polyurethane foam disk passive samplers in Kuwait, Turkey, Lebanon, Saudi Arabia, and Oman between January and October 2018. The study’s main goal was to initiate a passive air sampling network across the Middle East to generate comparable data, which will help report obligations of the various countries and be used in protocol discussions. The ∑24OCP concentrations were highest in the samples collected from Kartaba in Lebanon (7780 pg·m-3), and the lowest concentration was recorded at the BUTAL site in the Bursa province of Turkey (7.27 pg·m-3). The mean ambient ∑24OCP concentrations on a country-specific basis over consecutive sampling campaigns were: Lebanon (1680 pg·m-3) > Bursa (Turkey) (78.7 pg·m-3) > Oman (55 pg·m-3) > Kuwait (42 pg·m-3) > Jeddah, Saudi Arabia (19.1 pg·m-3). The results show no cancer risk due to inhalation of organochlorine pesticides (OCPs) in ambient air. This study provides the first reliable measurements of the spatial variability in the atmospheric concentrations of OCPs across several Middle Eastern countries, providing a baseline for assessing time trends in air, one of the core matrices for the effectiveness evaluation of the Stockholm Convention on Persistent Organic Pollutants.
中东五个国家选定的有机氯农药的环境空气浓度和风险评估
本文介绍了2018年1月至10月期间在科威特、土耳其、黎巴嫩、沙特阿拉伯和阿曼同时部署的聚氨酯泡沫盘被动采样器获得的数据。该研究的主要目标是在整个中东地区建立一个被动空气采样网络,以产生可比较的数据,这将有助于报告各国的义务,并用于议定书讨论。∑24OCP浓度在黎巴嫩Kartaba采集的样品中最高(7780 pg·m-3),在土耳其Bursa省BUTAL采集的样品中最低(7.27 pg·m-3)。在连续采样活动中,具体国家的平均环境∑24OCP浓度为:黎巴嫩(1680 pg·m-3);土耳其布尔萨(78.7 pg·m-3);阿曼(55 pg·m-3);科威特(42 pg·m-3);沙特阿拉伯吉达(19.1 pg·m-3)。结果表明,在环境空气中吸入有机氯农药(OCPs)不会导致癌症风险。本研究首次提供了几个中东国家大气OCPs浓度空间变异性的可靠测量,为评估空气中的时间趋势提供了基线,这是评估《关于持久性有机污染物的斯德哥尔摩公约》有效性的核心矩阵之一。
