In order to study the effect of heavy metal pollution on the community and the defense mechanism in the cell of phytoplankton, experiment was carried out around Yin-Yang Waters, northeastern Taiwan. Some statistical methods, such as cluster analysis, rank correlation analysis, correspondence analysis, diversity analysis and evenness analysis, were applied to explain the relationship between heavy metal and phytoplankton. Results of this study were as follow.
1. Depending cluster analysis, it indicated that the phytoplankton was influenced indeed by heavy metal.
2. Depending on rank correlation analysis, it showed that influence degrees of heavy metals on phytoplankton were Cu>Pb>Cr>Zn>Cd.
3. Phytoplankton species existing in the investigated waters could be divided into five growth kinds by correspondence analysis.
4. Diversity index became lower with increasing concentration of heavy metal. In a word, there were less phytoplankton species and cells in such serious metal polluted waters. Even some phytoplankton species reached the lethal threshold level.
5. Metallothioneins exist in cells of phytoplankton in the studied waters. Phytoplankton was induced to grow Metallothioneins for removing metal poison to survive in metal polluted environment.
6. Metallothioneins possess the ability to bind metal atoms. The rate of removing metal Cu using Metallothioneins-II was better than using Metallothioneins-I.
Marine phytoplankton is abundant but has a short life. Further, it should be feasible to plan to extract Metallothioneins from phytoplankton for applying to human health.
