2006年8月，一艘货船在阿比让各地的多个地点非法倾倒了500吨含有高浓度硫化氢的有毒废物。数千人患病。十七人死亡与有毒废物暴露有关。这项研究报告了与该事件相关的环境和健康问题。对五个垃圾倾倒场区进行了横断面研究。在这些家庭中，62.1%（n = 502）的家庭受到污染物的影响，这些家庭中51.1%的受访者（n = 2,368）有中毒迹象。最重要的症状是咳嗽（37.1%）、乏力（33.1%）、瘙痒（29.9%）和恶心（29.1%）。健康影响在五个废物影响地点表现出不同的频率。在中毒者中，21.1%（n = 532）在调查当天（即事件发生后 4 个月）出现症状。横断面采样可以确定距有毒废物处置点最多 3 公里的脆弱性暴露半径。较高脆弱性的区域受到各种环境因素的影响，例如污染地点的大小和严重程度、影响地点有毒废物污染的持续时间以及当地的气候条件。有必要监测对环境和人类健康的影响，以监测发展情况。
On August 2006, a cargo ship illegally dumped 500 t of toxic waste containing high concentrations of hydrogen sulphide in numerous sites across Abidjan. Thousands of people became ill. Seventeen deaths were associated with toxic waste exposure.This study reports on environmental and health problems associated with the incident. A cross-sectional transect study was conducted in five waste dumping site areas.Of the households, 62.1% (n = 502) were exposed to the effects of the pollutants and 51.1% of the interviewed people (n = 2,368) in these households showed signs of poisoning. Most important symptoms were cough (37.1%), asthenia (33.1%), pruritus (29.9%) and nausea (29.1%).The health effects showed different frequencies in the five waste impact sites. Among the poisoned persons, 21.1% (n = 532) presented symptoms on the survey day (i.e., 4 months after incident). Transect sampling allowed to determine a radius of vulnerability to exposure of up to 3 km from the point of toxic waste disposal.The area of higher vulnerability is influenced by various environmental factors, such as size and severity of pollution site, duration of toxic waste pollution on the impact site and locally climatic conditions. The surveillance of effects on environment and human health is warranted to monitor the development.
