Microplastic pollution has gradually become a major global concern, due to the widespread use of plastics. Microplastics enter the environment and are degradated, while also being ingested by organisms, affecting various physiological functions and adversely affecting the health of organisms. Microplastic pollution is currently a wide concern, but data on the impact on organisms is still not sufficient. Therefore, this review summarizes the research on microplastic pollution in marine, soil and fresh water, and its impact on organisms, focusing on the effects of microplastics on organisms' feeding behavior and oxidative stress responses, intestinal microbes and reproductive function, and the combined effects of microplastic pollutants on organisms. We also summarized the various possible ways of microplastics entering into the human body, and posing a potential threat to human health, which still needs further research. [ABSTRACT FROM AUTHOR]

Studies on the effect of CrylAb protein on hemocytes of the wolf spider Pardosa pseudoannulata revealed that CrylAb protein could accumulate in the four-instar and adult spiders via the food chain from transgenic rice expressing CrylAb protein through its prey brown planthoppers with approximate 20-time enrichment, but could not accumulate in hemolymph of the spider. The accumulated CrylAb had no significant effects on several elements of hemolymph including stored energy, calcium ion concentration and apoptosis rate of the hemocytes, indicating that CrylAb could not affect the hemocytes of P. pseudoannulata.
