“…The experiments with live plankton confirm the literature reports (Slauenwhite and Wangersky 1991, Volesky and Holan 1995, Moffett et al 1997 that live biomass absorbs trace metals. Sunda 1994 has shown how marine phytoplankton respond to trace metals (Figure 9).…”

“…Only a few reports have been published on the behavior of trace metals during phytoplankton bloom (Noriki et al, 1985;Kudo and Matsunaga, 1998). Some work on metal concentrations during phytoplankton bloom has been done in a controlled mesocosm (Wangersky et al, 1989;Slauenwhite and Wangersky, 1991).…”

The incidence of a large scale Trichodesmium erythraeum bloom along the southwest coast of India (Arabian Sea) observed in May 2005 is reported. Around 4802 filaments of T. erythraeum ml À1 seawater was observed and a colony consisted of 3.6 Â 10 5 cells. The bloom was predominant off Suratkal (12 59 0 N and 74 31 0 E) with a depth of about 47 m, covering an area of 7 km in length and 2 km width. The concentrations of Zinc, Cadmium, Lead, Copper, Nickel and Cobalt were determined in samples collected from the bloom and non-bloom sites using stripping voltammetry. The observed hydrographical and meteorological parameters were found to be favorable for the bloom. The concentrations of Zinc, Cadmium and Nickel were found to be higher at bloom stations, while the concentrations of Lead, Copper and Cobalt were found to be very low at bloom stations. Elevated concentrations of Cadmium and Cobalt were observed at Valappad mainly due to the decomposition of detrital material produced in the bloom. Statistically significant differences (P > 0.01) in metal concentrations between the bloom and nonbloom stations were not observed except for Copper. Metals such as Lead, Copper and Cobalt were removed from the seawater at all places where bloom was observed. Cadmium was found to be slowly released during the decaying process of the bloom.

“…The residence time was longer for Cu than for Zn, Pb, and Fe as has also been found in other lakes like L. Windermere, UK, L. Alpnach, L. Constanze, and L. Zürich, Switzerland (35). A common interpretation is that the mobility of Cu is enhanced by formation of organic complexes, which hamper the sorption of Cu in SPM as well as the uptake of Cu by biota (9,36,37).…”
