Public awareness of environmental issues has increased in the last two decades. Heightened concern over heavy metal contamination and its effects has been an integral part of this public interest. Multicellular organisms as indicators of toxicity present problems because of their complex organ systems, the lengthy time for toxicity to render visible symptoms, and problems of bioaccumulation. Alternatively, unicellular chlorophytes are desirable indicators of contamination because they are simple and sensitive. Chlamydomonas is an excellent indicator because it is ubiquitously distributed in water bodies (Yan and Stokes 1978). Alterations in the types of species of microalgae present in water bodies occur because of the impact of toxicants on their primary food sources. This, in turn, will adversely effect zooplankton and herbivore grazing populations (Havens and Heath 1991).
