Secondly, according to the construction and characteristic of the N-isopropylacrylamide and the temperature-sensitivity of PNIPA hydrogel, Pdualistic hydrogel was synthesized by microwave low temperature plasma. The effects of the factors on the swelling characteristic of P dualistic hydrogel, such as treatment time and power of plasma, concentrations of crosslinking agent and total monomers, proportion of AMPS, polymerizing temperature etc, was discussed in detail. The three dimensions structure , thermostability , reversional volume , swelling/deswelling kinetics, temperature-sensitivity and pH-sensitivity of the hydrogel were also investigated. The optimal synthesizing technics of P dualistic hydrogel initiated by microwave low temperature plasma was confirmed.

Results EROD activities in liver of wild crucian from Zhangtan, Jiangjunyan, Fuyang and Wenyan (23.51±4.17, 16.79±7.39, 18.74±5.16, 18.65±8.86 nmol/) were significantly higher than that of Jiekou (7.84±2.42 nmol/g promin), and no difference was observed between the other sites and Jiekou. Three dose groups (0.25, 0.50, 1.00L/dish water sample extracts) were used in Ames test. Reversional mutation rate of TA98 colony exposed to extracts from Zhangtan was 2.21, 3.39, 6.95 without S9, and 2.70, 4.07, 6.23 with S9, respectively. The revesional mutation of TA100 colony was 2.55, 2.81, 5.36 without S9, and 1.73, 2.86, 4.14 with S9, respectively. Reversional mutation rate of TA98 colony exposed to 1.00L/dish extracts from Jiangjunyan with S9 was 2.22, and there was a dose-response relationship in reversional colony count. Ames tests of the other extracts were negative.
