Inadequate provision of solid waste management facilities in Third World cities results in indiscriminate disposal and unsanitary environments, which threatens the health of urban residents. The study reported here examined household-level waste management and disposal practices in the Accra Metropolitan Area, Ghana. The residents of Accra currently generate large amounts of solid waste, beyond the management capabilities of the existing waste management system. Because the solid waste infrastructure is inadequate, over 80 percent of the population do not have home collection services. Only 13.5 percent of respondents are served with door-to-door collection of solid waste, while the rest dispose of their waste at communal collection points, in open spaces, and in waterways. The majority of households store their waste in open containers and plastic bags in the home. Waste storage in the home is associated with the presence of houseflies in the kitchen (r = .17, p < .0001). The presence of houseflies in the kitchen during cooking is correlated with the incidence of childhood diarrhea (r = .36, p < .0001). Inadequate solid waste facilities result in indiscriminate burning and burying of solid waste. There is an association between waste burning and the incidence of respiratory health symptoms among adults (r = .25, p < .0001) and children (r = .22, p < .05). Poor handling and disposal of waste are major causes of environmental pollution, which creates breeding grounds for pathogenic organisms, and the spread of infectious diseases. Improving access to solid waste collection facilities and services will help achieve sound environmental health in Accra.
第三世界城市固体废物管理设施供应不足,导致垃圾随意丢弃,环境不卫生,威胁城市居民健康。本文报道的研究调查了加纳阿克拉大都市区家庭层面的废物管理和处置做法。阿克拉居民目前产生大量固体废物,超出了现有废物管理系统的处理能力。由于固体废物基础设施不足,超过80%的人口没有家庭垃圾收集服务。只有13.5%的受访者享受上门收集固体废物服务,其余的人在公共收集点、露天场所和水道处理垃圾。大多数家庭将垃圾存放在家中的开放式容器和塑料袋中。家中存放垃圾与厨房中有家蝇有关(r = 0.17,p < 0.0001)。做饭时厨房中有家蝇与儿童腹泻发病率相关(r = 0.36,p < 0.0001)。固体废物设施不足导致固体废物被随意焚烧和掩埋。废物焚烧与成年人(r = 0.25,p < 0.0001)和儿童(r = 0.22,p < 0.05)呼吸道健康症状的发病率之间存在关联。垃圾处理不当是环境污染的主要原因,环境污染为致病生物创造了滋生地,导致传染病传播。改善固体废物收集设施和服务的获取将有助于在阿克拉实现良好的环境卫生。
