摘要：

Juveniles were more sensitive than adults, but Asiatic clam tissue and shell growth were significantly impaired for both juveniles and adults at 8.4-26.7 μg Cu/L in artificial streams. Tissue levels of Cu were 2.5-6 times greater at 8.4-26.7 μg/L exposure concentrations compared with background body burdens in unexposed clams. In studies conducted at the Clinch River, Virginia power plant, clam growth was reduced at 22.5-104.8 μg/L at a water hardness (180 mg/L) that was >2 times the hardness in artificial streams. -from Authors
