The Effect of Environmental Factors on Total Arsenic Accumulation in Sarcodia suiae, Rhodophyta.

Little is known about the effects of environmental factors on total arsenic (TAs) accumulation in marine Rhodophyta. The effects of five environmental factors (temperature, light intensity, pH, exposure duration, and phosphate) at various As(III) concentrations were investigated in Sarcodia suiae. The highest TAs accumulations were recorded at 25°C, a luminance of 80 µmol photons m s, and a pH of 8.
