水质基准是制定水环境质量标准,以及评价、预测和控制与治理水体污染的重要依据。为了系统分析水体硬度、物种门类和地域条件对水质基准的影响,本研究筛选了6门20科25种水生生物的毒性数据,用毒性百分数排序法推导了中国银的淡水生物水... 水质基准是制定水环境质量标准,以及评价、预测和控制与治理水体污染的重要依据。为了系统分析水体硬度、物种门类和地域条件对水质基准的影响,本研究筛选了6门20科25种水生生物的毒性数据,用毒性百分数排序法推导了中国银的淡水生物水质基准。研究结果表明,银的基准最大浓度(CMC)与水体硬度呈幂函数关系,等式为CMC=0.85×e[0.62ln(水体硬度)-4.28]μg·L-1,基准连续浓度为0.02μg·L-1。中国和美国2个不同生物区系研究都表明低等生物(无脊椎动物)比高等生物(脊椎动物)对银离子的毒性更为敏感。由地域条件引起的生物区系和敏感物种差异及基准推导方法的不同也会影响水质基准值。 展开更多

Based on material deposited in the Marine Biological Museum of the Chinese Academy of Sciences (Qingdao), a new species, Lurnbrineris sinensis sp. nov., as well as Augeneria albidentata (Ehlers, 1908), which is recorded for the first time from coastal water of China, are reported in the present paper. The specimens examined were collected during 1958 to 1960 from the Yellow Sea, East China Sea and South China Sea at depths of 4 to 182 m. 展开更多

The region of Tlemcen is situated in the north-west of Algeria. The aridity of the climate had lead to the development of the matorral, a state of degradation of the Mediterranean, and the composed xerophytes plants such as doum and diss, had been found. Chamaerops humilis, xerophyte plant, with special morphologic and botanic character presents a resistance of these climatic. The authors have proposed study of fauna closly linked to this plant. A faunistic inventory was realized in the Mansourah area (region of Tlemcen). Four stations have been described. Collecting sample was performed during June 2003-Mar. 2004, replying on sixteen (16) prelevements. The number of species were estimated of about 136, in which 111 are Arthropoda, the Entomofauna represented by 97 species and the other inventory are Arachnida by 8 species and Myriapoda by 6 species. 18 species are related to Gastropoda. The vertebrates are few. The importance of different groups' recolted on the Chamaerops humilis in the four stations is done particular to the insects. Analysis factorial correspondence (A.F.C) show different grouping of animal species. 展开更多
