The presence of trace organic pollutants in the effluent of wastewater treatment plants(WWTPs)poses considerable risks to aquatic organisms and human health.A large-scale survey of 302 trace organic pollutants in the effluent of 46 Chinese WWTPs was conducted to gain an improved understanding of their occurrence and ecological *** survey data showed that 216 compounds in 11 chemical classes had been detected in *** sum concentrations of the trace contaminants in effluent ranged from 1,392 ng/L to 35,453 ng/L,with the maximum concentration of perfluoroalkyl substances(PFASs)recorded as the highest(30,573 ng/L),which was markedly less than the reported 185,000 ng/L for the 38 American *** concentration of bisphenol analogs(BPs)was up to 4,422 ng/L,significantly higher than those reported in France,Germany,Japan,Korea,and the *** and BPs were the major pollutants,accounting for 59%of the total ***,a total of 119 contaminants were found to have ecological risks(RQ>0.01).Among these,23 contaminants(RQ>1.0)warrant higher attention and should be prioritized for *** study lists valuable information for controlling contaminants with higher priority in WWTP effluent in China.

We have numerically presented an actively mode-locked fiber laser with tunable repetition rate based on phase *** finely optimizing intra-cavity parameters,the ultrashort pulses with tunable repetitive frequency at giga hertz level can be easily generated due to the balance between dispersion and nonlinearity in the fiber laser *** the pulse frequency is changed from 1.0 GHz to 4.2 GHz,the spectral width increases from~15.65 nm to~27.25 *** addition,the corresponding pulse duration decreases from~81.59 ps to~31.57 ***,these output pulses with giga hertz repetitive rates and the picosecond widths can be further compressed by using the reasonable dispersion *** the pulse regime with repetition frequency at giga hertz level,the obtained smallest pulse duration is about~62 fs based on chirp pulse *** hope that these simulation results can promote further research and application in the ultrashort pulse lasers with high repetition rate.
