The Effect of Polyethylene Terephthalate Microplastics on the Growth of Mice

Abstract

Over the course of the previous decade, there has been a growing apprehension regarding the presence of MPs. This concern has arisen because of the detrimental effects of MPs pollution on the well-being of both animals and people. This study explores the potential implications of MPs contamination on mice. This study examined the impact of microplastics on mice by feeding four food experiment; P0 (pellet BR1), P1 (potato from Pujon Farm), P2 (potato mixed 300 µg PET) and P3 (potato mixed 600 µg PET). Body weight, feces weight, and left feed were observed in this study. Food contaminated with microplastics (MPs) has a negative effect on appetite, feces weight and body weight of mice. This process has an impact on reducing the weight of feces, appetite, body weight of mice and weight of mice. It is suspected that MPs in rat digestion increase concentrations of mice corticosterone metabolites and carcass fat, suggesting an adaptation of metabolism to this situation. Another impact is expected the decrease in microbial richness in the intestines of mice, causing a decrease in mice weight and body weight of mice. The high concentration of MPs entering the digestive tract can also reduce the rats’ appetite.
