Figure 1From: Fate and transport of metals in H2S-rich waters at a treatment wetlandThe solubility of amorphous CdS as a function of H2S concentration at pH = 7, 25°C (solubility curve calculated from Wang and Tessier[10]). Also shown is the Montana aquatic life standard for chronic exposure to cadmium, indexed to l00 mgL-1 CaCO3 alkalinity.Back to article page
