Despite Indonesia being considered as second highest source of marine plastic debris in the world, few studies have been conducted on plastic debris in Indonesia, particularly microplastics. By using a simple device to simultaneously grade floating microplastics, we investigated microplastic contamination in the ecosystem of small islands in Bintan Regency, Riau Island Province, Indonesia. The average number of floating microplastics from 11 beach stations around Bintan Island was 122.8 ± 67.8 pieces per station, which corresponds to 0.45 pieces per m3 and represents a low-medium microplastic pollution level compared to the levels of other marine environments worldwide. Polymer identification using Attenuated Total Reflectance-Fourier Transform Infrared (ATR-FTIR) Spectroscopy successfully identified Polyethylene (PE) (17.3 ± 8.3%), Low Density PE (17.6 ± 5.5%), Oxidized LDPE (<0.1%), Polypropylene (PP) (54 ± 13%), PP Atactic (<0.4%), PP isotactic (<0.2%) and Polystyrene (PS) (10.4 ± 9.1%) from different forms and shapes of microplastics i.e., fragments (50.9 ± 4.9%), fibers (26.2 ± 3%), granule (13.1 ± 3.8%) and films (9.8 ± 5.1%). We suggest that the generation of these microplastics was likely due to physicochemical processes, including biological degradation in this tropical ecosystem. Environmental implication of microplastics in this area increases the problems associated with ingestion, bioaccumulation and biomagnification across trophic levels and co-pollutants absorbed onto microplastics.
The current study examines the contamination of microplastics in three greenhouse types: abandoned, normal, and simple. The findings revealed that the abundance of microplastics was found to be the highest in the abandoned greenhouse, followed by the normal greenhouse and simple greenhouse. The mean abundance of microplastic organic fertilizer and irrigation water was also high.[…]
The study examines the distribution of residual film after eight years of film mulching in mid-April 2018. Results from the study revealed that eight years of mulching significantly increased the quantity of agricultural mulch film residues in the soil. The size of residual film fragments was found to vary from 0.25 cm2 to 109 cm2,[…]
A study in Yuanmou County, Yunnan Province, investigated microplastic pollution in different land uses, including facility farmland, traditional farmland, orchard, grassland, and woodland. Results showed a significant difference in microplastic abundance and characteristics between different land use types. Facility farmlands, traditional farmlands, and orchard lands had higher microplastic abundance than grasslands and woodlands. The main[…]
The study analysed 225 soil samples from maize planting zones in northern China, revealing that long-term plastic film mulching increases microplastic pollution in agricultural soils. The abundance of microplastics was significantly higher in mulched soils (754 ± 477 items kg-1) than in non-mulched soils (376 ± 149 items kg-1). The length of time with film[…]
The study examined the relative abundances and morphological distributions of microplastics (MPs) in water, sediments, and farmland soils in the Caohai Lake region. The estuary in the study area was considered a potential sink for MP transportation. Transparent and black MPs accounted for a large proportion of MPs in the five environments, with possible sources[…]
