Detection of microcystin in the water of Tai lake, Wuxi, China
| Water sample | Original Concentrationa (ng/mL) | Spiked concentrationb (ng/mL) | Detected concentrationc Mean±SD (ng/mL) | Recovery (%) Mean±SD |
|---|---|---|---|---|
| 1.04 | 0.1 | 1.09±0.03 | 95.61±2.6 | |
| Water from Tai | 1.69 | 1 | 2.65±0.05 | 98.51±1.9 |
| Lake | 2.87 | 2 | 4.58±0.19 | 94.05±3.9 |
| 5.61 | 5 | 10.75±0.23 | 101.32±2.2 |
a
Polluted water samples are from different areas of Tai lake. Original concentrations of MC-LR in the were determined by the standard ELISA protocol.
b
Different concentrations of MC-LR standard were added to the water samples. After thorough mixing and standing for at least 2 h, the samples were extracted by solid phase extraction to removing potentially interfering substances prior to assay. Samples were analyzed blind.
c
SD was calculated based on three experiment for each sample.
