Detection and Characterization of Microplastics in Soil and Dust from Urban Road Surface
AI summary Read the abstract
Researchers detected and characterized microplastics in road dust and soil from urban surfaces in Jambi City using FTIR, SEM-EDS, and binocular microscopy, identifying fiber, fragment, and other morphological forms and documenting the polymer types present in urban terrestrial environments.
This study aimed to classify the various forms of microplastics pollution present in the road dust and soil of Jambi City. We characterized the microplastics using FTIR, SEM-EDS, and binocular microscopy. The microplastics characterization under a microscope yielded forms such as fibers, fragments, and films. Polyethylene (PE), polyvinyl chloride (PVC), and polystyrene (PS) are the most common types of polymers, according to FTIR analysis. SEM-EDS analysis of microplastics elements showed that chlorine, silicon, carbon, aluminium, sodium, and calcium were the most abundant. The majority of the microplastics (MP) had an average maximum diameter of less than 200 µm. The results of the research indicate that polymeric materials from road dust wear off and travel through stormwater, eventually ending up in open waters and larger ecological niches, and are a major source of microplastics pollution.

Analysis of Microplastics Contamination on Road Dust Around Jambi's Angso Duo Market
AI summary Read the abstract
Researchers collected road dust from four sites around a busy market in Jambi, Indonesia, and found microplastic particles — fibers, fragments, and films — with polyethylene, polypropylene, and polystyrene identified by FTIR. The findings add to a growing body of evidence that road dust is an important atmospheric source of microplastics, with implications for inhalation exposure and stormwater runoff carrying these particles into urban waterways.

AI summary Read the abstract
Researchers systematically monitored microplastic contamination across multiple environments including a wastewater treatment plant, surrounding water bodies, and soils near plastic factories, characterizing shape, size, color, and polymer composition via microscopy and FTIR spectroscopy. They found fragments and fibers to be the most common microplastic shapes in water environments and documented simultaneous contamination across all sampled matrices.
Occurrence and characteristics of microplastics in surface road dust in Kusatsu (Japan), Da Nang (Vietnam), and Kathmandu (Nepal)
AI summary Read the abstract
Microplastics were detected in road dust sampled from three Asian cities (Kusatsu in Japan, Da Nang in Vietnam, and Kathmandu in Nepal), with concentrations and polymer types varying by city and sampling location. The study demonstrates that road surfaces are a major reservoir of microplastics in urban environments across diverse Asian contexts.
