Abstract
Introduction: The environment and human health can be negatively impacted by outdoor dust, which has always been a concerning issue. Microplastics are currently thought to be an increasing issue in air pollution. In Malaysia, however, the problem of microplastic contamination in outdoor dust is still relatively new and understudied. Microplastic distribution and characteristics were studied in outdoor dust form Putrajaya, Malaysia. Objectives: To provide understanding of microplastic pollution in outdoor dust in Putrajaya, Malaysia Methodology: A total of 40 outdoor dust samples were collected from six different types of land use in the district government area, commercial area, residential area and infrastructure and utility, civic and cultural and open spaces. The samples undergo processes such as organic matter removal using H2O2 solution, density separation using ZnCl2, filtration and drying process and lastly identification and characterisation by using microscope. Results and Discussion: All the outdoor dust samples from Putrajaya presented a variation length of microplastic particles with average size of 652.10 μm± 536.14μm. While among six different land uses, commercial area had the longest microplastic particles size (1074.26 μm ± 998.90 μm) and infrastructure and utility area had the shortest microplastic particle size (542.12 μm ± 447.20 μm) collected in outdoor dust from Putrajaya. For colours, black was the most abundant colour found which comprise 90% of the samples while orange colour being the least abundant colour with 0.22%. Fragments were the highest concentration found in all land uses (90%), followed by fibers (6%), and film (3%). According to this study, the different type of land use which include six types (government area, commercial area, residential area, infrastructure and utility area, civic and cultural area, and open spaces area) do not influence the occurrence of microplastic found in outdoor dust in Putrajaya. This study also found that environmental factors (rainfall, relative humidity, and temperature) do not correlate to microplastic size in outdoor dust from Putrajaya. Besides that, there were various potential sources (government events and gatherings, stormwater runoff, food and beverage services, improper waste management practices, littering, textile fibers, construction material, road surfaces, transportation activities, and public events and gatherings) found according to the land use categories which contributed to the occurrence of microplastic particles found in outdoor dust. Conclusion: This study investigates on the microplastic occurrence in outdoor dust in Putrajaya. Keywords: Microplastics, Outdoor dust, Characteristics, Land uses, Environmental factors
