Uptake, accumulation and translocation of traditional and novel organophosphate esters by rice seedlings in the presence of micro (nano)-polystyrene plastics: Effects of concentration and size of particles
|||||||||||||||

The study investigated the effects of polystyrene nanoparticles (MNPs) on the uptake of eight organic pollutants (OPEs) by rice seedlings. Results showed that OPEs accumulated in a concentration-dependent manner in both roots and shoots of rice seedlings. The impacts of MNPs were concentration- and size-dependent, influencing transpiration rate and antioxidant enzyme activities. Significant effects were found in exposure groups of medium-size and high-concentration MNPs. MNPs had more noticeable effects on OPE species with lower logKow in roots and more on species with higher logKow in shoots. A positive linear relationship was found between logTF and logKow, and a negative linear relationship between logRCF and logKow. The study highlights that the presence of MNPs could alter the characteristics of uptake, translocation, and accumulation of OPEs in rice seedlings, providing evidence for comprehensive control strategies for new pollutants.

Accumulation of microplastics in greenhouse soil after long-term plastic film mulching in Beijing, China

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.[…]

Temporal and Spatial Distribution of Residual Film in Soil Profile under Continuous Film Mulching

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,[…]

Effects of land use and landscape on the occurrence and distribution of microplastics in soil, China

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[…]

Exploring the Occurrence Characteristics of Microplastics in Typical Maize Farmland Soils With Long-Term Plastic Film Mulching in Northern China

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[…]

Distribution and migration characteristics of microplastics in farmland soils, surface water and sediments in Caohai Lake, southwestern plateau of China

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[…]
