- •
We assessed heavy metal risk in sediments-macrobenthos induced by freshwater releases.
- •
Heavy metal (As) exceeded the national standard value by more than 50%.
- •
The ranges of SFCI for each metal were generally larger in autumn than in spring.
- •
BSAF results suggest that Cd bioaccumulates from sediments to macrobenthos.
- •
Pollution-resistant species become dominant, providing an ecological risk evidence.
