Abstract

The menace caused by the inappropriate disposal of solid wastes in municipals is enormous. This has resulted in greenhouse gases and particulate matter emissions from these waste piles. This work studied the spatial and seasonal variation of particulate matter emissions from municipal solid waste dumpsites in selected towns in Anambra State, Nigeria. The study was conducted in the field and the Air Quality Meter (AQM-388 model) was used to obtain data on particulate matter and was conducted both during the wet and dry seasons. The result of the study showed that variations in the concentrations of PM1.0 exhibit highly significant differences (p < 0.01) across the seasons, with higher concentrations recorded during the dry season than in the wet season. Also, the observed PM2.5 levels exhibited highly significant differences (p < 0.01) across the seasons, with higher values recorded in the dry season compared to the wet season. The observed PM10 levels did not differ significantly across the seasons (p > 0.05). The level of three particulate matter including PM1.0, PM2.5, and PM10differ across the dumpsites, and the variations did not follow the same pattern. Seasonal influences played a significant role, particularly affecting PM1.0 and PM2.5, while PM10 exhibited relative stability throughout the seasons. The study reveals significant concentrations of particulate matter, highlighting the waste sector's substantial contribution to global emissions. The study recommended that collaborative efforts among stakeholders, including government bodies, environmental agencies, local communities, and waste management organizations, to collectively address the challenges posed by particulate matter emissions from dumpsites.
