Concentrations of Airborne Microplastics during the Dry Season at Five Locations in Bangkok Metropolitan Region, Thailand

Danuwas Sarathana et al.

Summary: Information on airborne microplastics (AMPs) in Thailand is lacking. This study examined AMPs in Bangkok Metropolitan Region (BMR) using a high-volume air sampler at five different locations. The results showed that AMPs concentrations varied across locations, with the dumpsite having the highest concentration. The shape analysis revealed that the majority of AMPs were in fragment form, with polyethylene (PE) and cellophane being the predominant types.

High temporal resolution records of outdoor and indoor airborne microplastics

Lucy C. Boakes et al.

Summary: A proof-of-concept study used a Burkard volumetric spore trap to investigate the hourly deposition and concentration patterns of airborne microplastics. The study found clear daily and weekly patterns in microplastic concentrations, with higher levels indoors and lower levels in rural outdoor areas.

Occurrence and human exposure risks of atmospheric microplastics: A review

Zhen Yuan et al.

Summary: This review summarizes the current state of knowledge about microplastic pollution in the atmosphere, discussing sample types and factors affecting transport and deposition. Microplastics have been found in various forms in the atmosphere worldwide, but their abundance varies across regions. Human activities and meteorological factors greatly influence the abundance of atmospheric microplastics, but the mechanisms underlying their transport and deposition processes remain unclear. Inhalation of atmospheric microplastics poses potential health risks, with different levels of intake for adults and children.

Microplastics and nanoplastics in the marine-atmosphere environment

Deonie Allen et al.

Summary: The study analyzes the processes and fluxes of the marine-atmospheric micro(nano)plastic cycle and highlights the limited observations. A global observation strategy for marine-atmospheric micro(nano)plastics is proposed to address the uncertainties and knowledge gaps.

Environmental and health impacts of contaminants of emerging concerns: Recent treatment challenges and approaches

Deepak Yadav et al.

Summary: The research discussed the adverse effects of CECs on human health and the environment, emphasized the important role of water medium in the dissemination of CECs, and noted that the technology for treating CECs remains inadequate. Biochar as an economically effective technology has been proposed, and bibliometric analysis has been conducted to understand the research trends in related treatment techniques.
