Microplastic deposition flux and morphology in atmospheric fallouts of Ho Chi Minh City (Vietnam) sampled from June 2018 until June 2019
AI summary Read the abstract
Researchers measured the deposition flux and morphology of atmospheric microplastics in dry and wet fallout samples collected monthly over one year at three sites in Ho Chi Minh City, Vietnam. They found consistent atmospheric microplastic deposition across all sites, with fibers and fragments being the most common types. The study provides one of the first quantitative atmospheric microplastic datasets for a major Southeast Asian megacity.
Microplastic, i.e. size 300µm-5000µm, deposition flux and morphology, i.e. type (line, fragment), size (length and area) and colour, were measured in dry and wet atmospheric fallouts sampled at Ho Chi Minh City at three sites (CC: Cu Chi; D10 district 10; PH Phuoc Hiep), two times a month, from June 2018 until June 2019. Dry and wet atmospheric fallouts were analysed in the lab for microplastic extraction following the steps: sieving, enzygmatic digestion, naCl density separation, filtration on GF-A filter and stereomicroscope analysis (300-5000µm).

Researchers measured atmospheric wet and dry deposition of microplastics over one year in Guangzhou, China, a subtropical megacity. They found deposition fluxes ranging from 51 to 178 particles per square meter per day, with fibers, fragments, films, and microbeads all detected, indicating that atmospheric transport is a significant pathway for microplastic distribution in urban environments.

Preliminary assessment on the microplastic contamination in the atmospheric fallout in the Phuoc Hiep landfill, Cu Chi, Ho Chi Minh city
AI summary Read the abstract
Researchers collected atmospheric fallout near a landfill in Ho Chi Minh City, Vietnam and found microplastics present, with abundances comparable to studies from developed countries. The study provides early evidence of airborne microplastic deposition near waste sites in developing countries, where plastic waste management is often inadequate.
