INFLUENCES OF ARSENIC ON FRESHWATER BIOFILMS, FISH AND THEIR NUTRIENT CYCLING INTERACTIONS
Arsenic and other metal(loid)s are released from mining or industrial activities and enter to water and soil
Biofilm modulates As toxicity to fish
Objective
Experimental set up
Arsenic fate
As effect on structural and functional attributes of biofilm
Arsenic effect on fish growth
Concluding remarks

Concluding remarks
Our results highlight the interest and application of incorporating some of the complexity of natural systems in ecotoxicology
Support the use of criterion continuous concentration (CCC) for arsenic lower than 150 μg/L and closer to the water quality criteria to protect aquatic life recommended by the Canadian government (5 μg As/L).
