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 wi…
