THE EFFECTS OF MERCURY ON THE GROWTH OF Phaeodactylum tricornutun AND THE ACCUMULATION AND ELIMINATION OF MERCURY BY THE DIATOM

Abstract:

The effects of mercury in different concentrations on the growth of a diatom, Phaeodactylum tricornutun, and the accumulation and elimination of mercury by the diatom have been studied using ²⁰³HgCl₂ as a radioactive tracer. When there was 0.0182±0.0061ppm mercury in the sea water, the diatoms grew normally, and their ability to accumulate mercury was great with a concentration factor of 18790. When, however, the concentration of mercury was≥0.0272±0.0092 ppm, the diatoms were damaged, and some of them died with a concentration factor of 7209. The variations of growth and accumulation between normal and damaged diatoms are also discussed.
