| 英文摘要 | Concerns about microplastic (MP) pollution in terrestrial systems are increasing. It is believed that the overall amount of MPs in the terrestrial system could be 4-23 times higher than that in the ocean. Agricultural ecosystems are among the most polluted areas with MPs. Terrestrial organisms such as ground beetles, will be more vulnerable to MPs in various agricultural soil types because they are common in garden and agricultural areas. Therefore, this work aims to assess for the first time the potential adverse effects of chronic exposure for 30 days of ground beetles to a field-realistic concentration of 2 % (w/w) of three different irregularly shaped MPs polymers: Polystyrene (PS), polyethylene terephthalate (PET), and polyamide 6 (PA; i.e., nylon 6) on their health. The results showed no effect on beetle survival; nevertheless, there was a decrease in beetle defecation rate, particularly in beetles exposed to PS-MPs, and a change in the activity of midgut digestive enzymes. The effects on digestive enzymes (amylase, protease, lipase, and alpha-glucosidase) were polymer and enzyme specific. Furthermore, histological and cytological studies demonstrated the decomposition of the midgut peritrophic membrane, as well as abnormally shaped nuclei, vacuolation, disordered microvilli, necrosis of goblet and columnar cells, and necrosis of mitochondria in midgut cells. Given the importance of ground beetles as predators in most agricultural and garden settings, the reported adverse impacts of MPs on their health may impact their existence and ecological functions. |
