Heavy metals in surface sediments from Minjiang Esturary—Mazu and Xiamen—Jinmen sea areas

The concentrations of Cu,Pb, Zn and Cd in surface sediments from Minjang Estuary-Mazu and Ziamen-Jinmen sea areas of China were investigated during 1995-1996.The concentration ranges of Cu,Pb ,Zn and Cd in the Minjiang Estuary-Mazu sea area were 16.4-37.2,33.4-69.6,92.1-128,0.087-0.036mg/kg(dry wt.),respectively; those for Xiamen-Jinmen sea area were 11.0-24.5,36.0-80.3,77.5-161,0.135-0.285mg/kg(dry wt.), respectively.The concentration and distributions of Cu,Pb,Zn and Cd in surface sediments of Minjiang Estuary-Mazu and Xiamen-Jinmen sea areas were analyzed and evaluated.The results showed that the values of Zn and Pb exceeded those of sediment quality criteria.The average concentration of Cu in Minjiang Estuary-Mazu sea area was higher than that in Xiamen-Jinmen sea area.The obviously higher concentrations of Cu,Pb, Zn and Cd were found at outlets of Minjiang and Jiulong River.From the estuaries to open sea, the concentrations of Cu, Pb,Zn and Cd had a decreasing trend, and then elevated in the sea areas near Mazu and Jinmen, suggesting that Cu,Pb,Zn and Cd in Minjiang Estuary-Mazu and Xiamen-Jinmen sea areas may come from both the mainland and Taiwan of China.     

2-Chlorophenol oxidation kinetic by photo-assisted Fenton process

Experimental data are presented to test and validate a kinetic model for the oxidation of 2-chlorophenol wastewater by photo-assisted Fenton process. The data showed that this process had produced good effects under acidic conductions. Up to 90% 2-chlorophenol was removed after 90-minute reaction time with H2O2 of 25% CODCr. in, while in UV/H2O2 system ordy 16.8% 2-chlorophenol was removed after one hour treatment. The optimal pH in this reaction occurred between pH 3.0 and pH 4.0. The reaction kinetics for photo-assisted Fenton process experimented in this research was investigated. Kinetic models were proposed for the treatment of 2-chlorophenol wastewater. The reaction was found to follow the 2nd order. The equations of reaction kinetics are as follows:-d[RH]/dt=KRH[RH][H2O2]0exp(-KH2o2t);-d[CODCr]/dt=KCODCr[CODCr][H2O2]0exp(-K′t).The prediction of the models was found to be in a good agreement with experimental results, thus confimfing the proposed reaction mechanism.     

上海市大气PM2.5中溶剂可抽提有机物的特征研究

利用溶剂抽提、分离、毛细管气相色谱-质谱联用技术对2000年10月至2001年8月上海市5个不同功能区采集的大气PM_(2.5)样品中的溶剂可抽提有机物进行了检测,共检测出正构烷烃、单环芳烃、多环芳烃、有机酸、有机醇、有机酯等各类溶剂可抽提有机化合物267种。检出的82种多环芳烃中有15种属于美国EPA优先控制污染物名单。比较了不同季节、不同区域PM_(2.5)样品中正构烷烃、多环芳烃等化合物分布特征的差异。检出的喹啉类含氮杂环类化合物以及有机酸等污染物表现出一定的机动车排放特征。

海水、大气化学演化对动物起源和进化方向的制约

动物的起源主要依赖于氨基酸等有机小分子在海水中能否进行脱水缩合反应而生成生物高分子，后者则依赖于海水pH值升高和大气CO2浓度降低的历史演化进程。有机小分子只有在海水pH值演化到近中性，即寒或纪时彼此才能发生脱水缩合反应而合成生物高分子。只有大气CO2分压降到1000Pa以下，即泥盆纪以后，陆地上才能出现稳定的土壤层和植物，动物也才能从海洋扩展到陆地。随后大气CO2浓度继续降低导致了气温下降和植物生长率的衰减，促使动物进一步演化。
