Many impoverished communities in South Africa (SA) simultaneously face multiple preventable socioenvironmental hazards associated with elevated burdens of ill health. One such hazard is failure to institute effective buffer zones between human settlements and point sources of pollution such as airports and industrial zones.
To gather information on living conditions, housing quality and health status in two poor communities in the SA coastal industrial city of Port Elizabeth.
The study was undertaken in Walmer Township, situated in close proximity to Port Elizabeth International Airport, and Wells Estate, which borders two industrial sites. Approximately 120 households were randomly selected from each study site. Following written informed consent, information on the neighbourhood environment and housing conditions was collected through administration of a structured questionnaire.
The two study sites were similar in respect of household language, income, education, high levels of debt servicing and high reliance on social grants. Relative to Walmer Township, higher levels of indoor dust and bad odours in the neighbourhood were reported in Wells Estate, as were higher rates of selected respiratory ill-health symptoms. Upper respiratory tract symptoms were significantly associated with reports of high levels of indoor dust, while lower respiratory tract symptoms were significantly associated with low income, overcrowding, and having a young child in the household.
The study highlights a scenario of a triple environmental hazard to health in the study communities: (i) poverty; (ii) poor-quality housing; and (iii) lack of an effective buffer zone between the study communities and local point sources of pollution. Respiratory ill-health conditions were significantly associated with poverty, household composition and living conditions.
南非(SA)的许多贫困社区同时面临着多种可预防的社会环境危害,这些危害与健康负担加重有关。其中一个危害是未能在人类住区和机场及工业区等污染点源之间建立有效的缓冲区。
收集南非沿海工业城市伊丽莎白港两个贫困社区的生活条件、住房质量和健康状况信息。
该研究在瓦尔默镇(Walmer Township)进行,该镇紧邻伊丽莎白港国际机场,而威尔斯庄园(Wells Estate)则与两个工业区接壤。从每个研究地点随机选择了大约 120 户家庭。在获得书面知情同意后,通过管理结构化问卷收集了有关邻里环境和住房条件的信息。
两个研究地点在家庭语言、收入、教育、高偿债水平和高度依赖社会补助方面相似。与瓦尔默镇相比,威尔斯庄园报告的邻里室内灰尘和异味水平更高,选择的呼吸道疾病症状发生率也更高。上呼吸道症状与室内灰尘水平高有关,而下呼吸道症状与收入低、过度拥挤以及家中有小孩有关。
该研究强调了研究社区中三重环境健康危害的情况:(i)贫困;(ii)住房质量差;(iii)研究社区与当地点源污染之间缺乏有效的缓冲区。呼吸道疾病与贫困、家庭构成和生活条件显著相关。
