ABSTRACT
Studies on toxicities and tolerances of Cu in the blood cockle Anadara granosa were conducted by 48-hour toxicity testing using endpoint mortality. The 48-hr LC50 of Cu was 0.29 mg/L. The values of condition index reduction were positively related to increasing levels of Cu exposure. This laboratory study suggested the potential of condition index of A. granosa as a physiological indicator of Cu pollution. In addition, the present LC50 value indicated that A. granosa is a potential biomonitor of Cu pollution based on the laboratory results.
Key words: Toxicity, Anadara granosa, biomonitor
