Toxicity to Aquatic Life
LC10 values at 0.8μg L-1 for certain freshwater fish species (ex. rainbow trout)
No Observed Effect Concentration (NOEC) as low as 0.001μg L-1 (Ceriodaphnia dubia) compared to 2mg L-1 for freshwater/seawater algae
Ag ions can reach branchial epithelial cells by Na+ channels coupled to proton ATPase in apical membrane of gills, travel to the basolateral membrane and block Na+/K+ ATPase influencing ionoregulation of Na+/Cl- ions
