Plastic pollution is becoming a growing concern on coastal tourism sites. Unquantified amounts of plastic materials are discharged into coastal waters with detrimental effects on local marine environments. With the expansion of the tourism industry, waste increasingly originates from tourism activities and ends up into the ocean due to poor management of solid waste post-consumption. This study explores the sources, abundance, and type of litter in Zanzibar, Tanzania by surveying four coastal tourism sites. The analysis illustrates the contributions to plastic pollution of four sectors of Zanzibar's economy (residential households, building and construction, tourism, and commercial sector). Findings suggest that plastic accounted for almost half (48.5%) of the waste inflow to the environment, and single-use packaging was the dominant litter item on all sampled sites.
塑料污染在沿海旅游区日益受到关注。大量的塑料材料未经量化就被排放到沿海水域，对当地海洋环境造成了有害影响。随着旅游业的扩张，由于消费后固体废物管理不善，越来越多的废物源自旅游活动并最终进入海洋。本研究通过调查坦桑尼亚桑给巴尔的四个沿海旅游区，探讨了该地区的垃圾来源、数量和类型。分析表明，桑给巴尔经济的四个部门（居民家庭、建筑和施工、旅游和商业部门）对塑料污染的贡献。研究结果表明，塑料几乎占流入环境的废物的一半（48.5%），所有抽样点的主要垃圾都是一次性包装。
