家庭或家庭层面的塑料垃圾露天焚烧是空气污染物和温室气体的来源，而这些往往在排放清单中被忽视。在危地马拉，由于无法获得废物收集服务，尤其是在农村地区，家庭露天焚烧是一个相当令人关切的问题。本文首次尝试估算危地马拉城市和部门层面的家庭露天焚烧垃圾的排放量。从危地马拉雅拉帕的哈拉潘地区收集了数据，并进行了分析，以确定塑料废物产生随时间的变化以及可能影响塑料废物产生和焚烧程度的社会经济因素。每年人均塑料垃圾焚烧量被用来估计哈拉潘地区、朱蒂亚帕市和危地马拉市以及危地马拉所有22个省的家庭露天焚烧塑料垃圾的排放量。我们的结果显示，农村地区在国内燃烧更多的垃圾，可能是因为无法收集垃圾，而危地马拉30.4%的OC、24.0%的BC、23.6%的PM2.5和2.4%的二氧化碳排放可能无法解释排除露天塑料燃烧作为来源的原因。家庭或家庭层面的塑料垃圾露天焚烧是危地马拉经常被忽视的空气污染物和温室气体的重要来源。
Domestic, or household-level, open burning of plastic waste is a source of air pollutants and greenhouse gases that are often neglected in emission inventories. Domestic open burning is a considerable concern in Guatemala due to the lack of access to waste collection services, particularly in rural areas. This paper offers the first attempt to estimate emissions from the domestic open burning of waste at the city and departmental levels in Guatemala. Data were collected from the Xalapán region of Jalapa, Guatemala and analyzed to determine the change in plastic waste generation over time as well as the socioeconomic factors that may affect the extent of plastic waste generation and burning. The annual per capita masses of plastic waste burned were used to estimate emissions from domestic open burning of plastic waste in the region of Xalapán, the cities of Jutiapa and Guatemala city, and all 22 departments in Guatemala. Our results show that rural areas burn more waste domestically, likely because of a lack of access to waste collection, and 30.4% of OC, 24.0% of BC, 23.6% of PM2.5, and 2.4% of CO2 emissions in Guatemala may not be accounted for by excluding open plastic burning as a source. Domestic, or household-level, open burning of plastic waste is a substantial source of air pollutants and greenhouse gases that are often neglected in Guatemala.
