Toxicity test - Opis:
- Cadmium wastewater released by human activities will eventually enter the aquatic environment. Living organism that lives around could potentially exposed by these cadmium, including C. gracilis which play a critical role as a primary producer. Cadmium can reduce the growth rate and pigment content in C. gracilis. Therefore, toxicity testing becomes important to do considering that C. gracilis has many benefits such as shrimp feed and have active compounds for antibacterial and biodiesel. Toxicity test was performed in 96-hours with a series of concentration 0, 0.56, 1.0, 1.8, 3.2, 5.6 mg/L. IC50 cadmium results in concentrated cell density and chlorophyll-a C. gracilis were 1.62 mg/L and 3.4 mg/L, while carotenoids were not in accordance with the contribution of cadmium. NOEC and cadmium LOEC to C. gracilis cell density were 0.56 mg/L and 1.0 mg/L.
