Uji Toksisitas Cu Dan Cd Terhadap Pertumbuhan Chlamydomonas Sp.

---

Heavy metals are generally a problem even at world level as a threat to humans themselves. Heavy metal pollutant can affect aquatic organism’s life and many of them are Cu and Cd. Cu and Cd are heavy metals that are at high toxic level although Cu is included in essential metals but at high concentration levels can cause high toxic effect. If phytoplankton are inhibited by heavy metals, it will led to food chains in aquatic ecosystem. Chlamydomonas sp. is the dominant type of microalgae in the aquatic ecosystem and directly receives impact of the heavy metal. This study aimed to compare the effect of Cu and Cd on the growth of Chlamydomonas sp. Toxicity testing procedure follow the standard methods of Asean-Canada Cooperative Program on Marine Science Phase-II (ACCPMS-II). The results obtained IC50-96 hours of heavy Cu metal on the growth of Chlamydomonas sp. was 0.6 mgL-1, and for heavy metals Cd for the growth of Chlamydomonas sp. was 24.92 mgL-1. Both heavy metals Cu and Cd proved to inhibit the growth Chlamydomonas sp. From the IC50-96 hour value shows Cu is more toxic compared to Cd. Cu toxicity is 42 times greater than Cd. The NOEC values for Cu are < 1 mgL-1 and 18 mgL-1 for Cd. LOEC value for Cu is 1 mgL-1, while for Cd is 32 mgL-1.
