| Summary: | Continuous monitoring of metals is necessary due to the influx of metals
into the environment from human activities. The presence of green algae
Spirogyra in various water bodies can be used as an effective bioindicator
for the detection of metals. In this paper, naturally available pigments in
Spirogyra- chlorophylls and carotenoids were used to detect the presence of
light metals by measuring the light absorbance at λ = 663 nm and 450 nm
respectively, before and after the exposure to Ca and Na. The results showed
both markers were sensitive to the presence of Ca and Na in aqueous
environment, with carotenoids gave a better response. As all markers
showed high correlation to the concentration of metals within 0.001 mg/L -
0.100 mg/L, Spirogyra had great potential to be as bioindicator for Ca and
Na in aqueous environment. |
