| 研究開始時の研究の概要 |
The specific content of this research is described as below:
(1) the effects of MPs (at different concentrations) on physicochemical properties of soil,
(2) the impacts of MPs (at different concentrations) on biochemical, physiological traits, and plant growth at different intervals,
(3) the bioaccumulation potential of MPs in plants, and
(4) the effect of MPs (different concentrations) on physiological, biochemical, and gut microbial community attributes of earthworms.

| 研究実績の概要 |
This study explored the effect of non-biodegradable (low density polyethylene; LDPE) and biodegradable (polybutylene succinate-co-adipate; PBSA) microplastics on earthworm Eisenia fetida during vermicomposting of cow dung. Earthworms were exposed to different concentrations (0%, 0.5%, 1% and 2%) of LDPE and PBSA of 2 mm size. The cow dung supported the growth and hatchlings of earthworms, and the toxicity effect on Eisenia fetida was analyzed. Microplastics decreased the body weight of earthworms and there was no impact on hatchlings. Much significant changes with varying microplastics concentrations were not obvious. SEM and FTIR-ATR analysis observed the surface damage of earthworms, morphological and biochemical changes at higher concentrations of both LDPE and PBSA.
