Pollution monitoring of three rivers passing through Fuzhou City, People's Republic of China.
The Tradescantia-micronucleus (Trad-MCN) bioassay was used to determine the pollution levels of three rivers passing through Fuzhou city. Results indicate that all three rivers are polluted but at different levels. They are ranked as follows: Antai River > Baima River > Jinan River. Positive results were obtained when full strengths of the water samples were used to treat the plant cuttings when compared with the negative control (tap water) group. Negative responses were obtained when the Baima and Jinan river water was diluted to 50% but not for the sample from the Antai river. Micronuclei frequencies of the Antai river group were higher than the positive control using the Ping-Yang antibiotic drug (Huapei Drug Manufacturer) at 0.2 microg/ml concentration.
