Efek Pb Dan Cd Terhadap Pertumbuhan Trachelomonas Sp.

---

Abstract
Heavy metals are generally a problem even at the world level as a threat to
humans themselves. Heavy metal pollutants can affect the life of aquatic
organisms and many of them are Pb and Cd. Pb and Cd are heavy metals that are
at high toxic levels. Phytoplacton Trachelomonas sp. which are primary producers
in the food chain in aquatic ecosystems, are the first objects to be affected by
heavy metal contamination. Heavy metal toxicity test of Pb and Cd was carried
out on the phytoplankton Trachelomonas sp. because it is dominant in the aquatic
ecosystem. The research was carried out in March-May 2021. Toxicity test
method used was the Asean-Canada Cooperative Program on Marine Science
Phase-II (ACCPMS-II 1995). The results of IC50-96 hours of Pb and Cd on the
growth of Trachelomonas sp. are 2.78 mgL-1 and 4.15 mgL-1. The value of
NOEC-96 hours of Pb and Cd on the growth of Trachelomonas sp. are 1 mgL-1
and 1 mgL-1, respectively. The value of LOEC-96 hours of Pb and Cd on the
growth of Trachelomonas sp. are 1.8 mgL-1 and 1.8 mgL-1. From the IC50, NOEC
and LOEC values, it can be concluded that Pb is more toxic to Trachelomonas sp.
than Cd so that it can be used as a bioindicator of Pb heavy metal pollution.
Keywords : Pb, Cd, Trachelomonas sp. IC50-96 hour, NOEC, LOEC
