The Effects of different concentrations of microplastics based on the feeding ability rate of oysters
Summary
Researchers found that oysters exposed to microplastic concentrations above 5 mg/L showed significantly reduced feeding and filtration rates, with higher concentrations causing greater disruption, suggesting that microplastic pollution could impair the health and ecosystem function of commercially and ecologically important shellfish.
In order to explore the relationship between the feeding ability of oysters and microplastics, the changes in the feeding rate of oysters under different concentrations of microplastics can be studied in the laboratory. The results show that the four concentrations set in the experiment are above 5 mg It has a significant effect on the water filtration green and food intake rate of oysters, and the absorption rate and food intake rate decrease with the increase of microplastics concentration; when the concentration is 5mg \ L, the indicator is in a normal state. According to the research results, when the concentration is 5mg \ L, the feeding ability of oysters is ideal, which is suitable for the transformation and circulation of oysters in vivo.
