流行病学在环境质量现状评价中的应用

在阐述流行病学和环境质量现状评价概念的基础上,探讨了应用流行病学的基本原理与方法来评价环境污染效应,提出了这种应用在全面评价环境质量的现状以及制定卫生标准与采取正确的预防措施方面,是一种值得研究的方法。     

水源有机污染对饮用水质的影响研究

对松花江S水源地及H市饮用水进行连续监测,江水中定性检出的有机污染物,在饮用水中绝大多数都可以检出,说明水厂传统的常规处理工艺对于有机污染物去除率较低,致使一些有机污染物残留在饮用水中,对沿江居民健康产生危害.

The use of bioluminescent biotests for study of natural and laboratory aquatic ecosystems

A set of bioluminescent tests was developed to monitor water quality in natural and laboratory ecosystems. It consisted of four bioluminescent systems: luminous bacteria, coupled enzyme system NADH:FMN-oxidoreductase-luciferase and triplet enzyme systems with alcohol dehydrogenase and trypsin. The set of biotests was applied for a small forest pond (Siberia, Russia), laboratory microecosystems polluted with benzoquinone and a batch culture of blue-green algae. Thereby effects of natural water compared to those of models of heavy pollution and “bloom” of blue-greens on the bioluminescent tests were revealed. The set of biotests was not affected by a natural seasonal variability of water quality in the unpolluted pond, but responded to the heavy pollution and the “bloom” of blue-greens. The set of biotests could be recommended as the alarm test to control the acute toxicity of natural water bodies.     

Heavy metal monitoring of marine algae from the Turkish Coast of the Black Sea, 1998-2000

Concentrations of Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn were determined in macroalgae samples collected from the Turkish Coast of the Black Sea. Certain algae species were chosen among the green, brown and red algae species at Sile and Sinop sampling stations from 1998 to 2000. In general, as regards the influence of the collection sites on the whole metal accumulation, Sinop is considered to be more polluted than Sile. The concentrations of the heavy metals in Cystoseira barbata algae are compared with previous studies in the same stations. The results showed that all metal levels have gradually decreased during past years. At the same time, Cd, Co, Cr, Cu, Fe, Ni and Pb levels in the present study are lower than in Bosphorus and Marmara Sea algae. However, Mn and Zn concentrations are higher than Bosphorus but lower than at Marmara. According to these findings the heavy metal pollution decreased in Turkish Coast of the Black Sea during the years investigated.
