珠江三角洲一些城市水体中微量有机氯化合物的初步分析

采用较快速、简便的方法，用ＧＣ／ＥＣＤ对珠江三角洲几个城市中的污水及深圳河，大沙河中的有机氯化合物进行了初步探查及半定量分析。结果表明，几种有机氯农药尽管已停止生产多年，但在污水及河水中仍有残留，其中ＤＤＴ及其衍生物ＤＤＥ含量在０．０２－０．５０μｇ／Ｌ范围内；ＢＨＣｓ在０．０４－０．７２μｇ／Ｌ范围内，氯苯类化合物及ＰＣＢｓ在污水及不中也被检出。     

新疆玛纳斯河流域农业水资源可利用潜力分析

结合新疆玛纳斯河流域水文水资源、种植结构和节水技术发展等资料,从开源、节流两方面对流域近期(至2010年)、中远期(2010-2030年)农业水资源极限潜力、可挖掘潜力进行了估算。结果表明,就目前水资源的利用水平和开发趋势,玛纳斯河流域未来农业水资源的主要利用途径是开源与节流相结合,以节流为主。全流域尚有的农业灌溉水资源极限潜力为10.75×10⁸m³,近期农业水资源可挖掘潜力为2.13×10⁸m³,其中开源增水潜力0.40×10⁸m³,占18.8%,节流增水潜力1.73×10⁸m³,占81.2%;中远期农业水资源可挖掘潜力5.33×10⁸m³,其中开源增水潜力1.12×10⁸m³,占21.0%,节流增水潜力4.21×10⁸m³,占79.0%。该研究对区域制订节水灌溉规划及水资源系统优化配置具有重要参考价值。     

运用生物循环理论建立多元生物污水处理新工艺

以活性污泥法为主流工艺的现代污水处理技术,存在着工程投资大，运行费用高，管理复杂等缺点，按照生物循环基本理论要示是不完善的。多元生物污水处理是按照食物链代谢规律,运有生物循环理论，设计成微生物－植物－水生动物3个处理单元。污水中的有机物作为微生物人良料在第1单元被套氧微生物消化降解成CO2，H2O，NH^ 4,CH^-4等，除CH4作为生物能源可回收利用外，其它物质是植物的营养物质，在第2单元藻类等多种植物吸收，通过光合作用合成植物细胞，并释放氧气，在第1单元和第2单元增殖的细胞和藻类成为水生动物的食料，在第3单元被浮游动物和鱼类捕食，转化成动物蛋白，污水中的有机物在3个单元组成的生态净化系统中，被多样生物逐级利用，最终转化成植物细胞和动物蛋白，使污水得到净化，达到三级处理水平，不产生二次污 ，是一种安全的，对环境友好的污水处理新技术，在国外被誉为21世纪的新科技。该污水净化系统，按照生物循环基本理论进行工艺设计，通过生态平衡自我调控，具有工艺流程简单，投资省，运行费用低，管理简便等优点，适合我国国情，有广阔的应用前景，尤其适有于小城镇污水处理。

Gamergates in the myrmicine genus <Emphasis Type="Italic">Metapone</Emphasis> (Hymenoptera:Formicidae)

Gamergates (i.e. mated reproductive workers) are mostly known from ant species within the Ponerinae. We report here the discovery of gamergates in two species of the subfamily Myrmicinae. Until now, mated reproductive females in colonies of myrmicine species have been considered morphologically distinct from the worker caste. However, in two species of the myrmicine Metapone (Metapone madagascarica and a newly discovered, not yet described Metapone species) all workers have six ovarioles and a spermatheca; and some of them are mated. There are no morphological differences between mated and non-mated workers. Field observations and laboratory studies indicate that colonies of the Metapone species can reproduce with gamergates only.     

Vocal acrobatics in a Chinese frog, <Emphasis Type="Italic">Amolops tormotus</Emphasis>

Although amphibians are highly vocal, they generally emit only a limited number of acoustic communication signals. We report here the extraordinarily rich vocal repertoire of Amolops tormotus, a ranid species in China. These frogs produce countless vocalizations, some of which share features of birdsong or primate calls, e.g., ultrasonic frequency components, multiple upward and downward FM sweeps, and sudden onset and offset of selective harmonic components within a call note. Frame-by-frame video analysis of the frog's calling behavior suggests the presence of two pairs of vocal sacs that may contribute to the remarkable call-note complexity in this species.

Inventory of emissions from major air pollutant categories in Turkey

In this study, an inventory of air pollutant emission estimates from major air polluting sources in Turkey for period between 1985 and 2005 with 5-year intervals were estimated. Inventory covers anthropogenic sources of five major air pollutants of particulate matter, sulfur dioxide, carbon monoxide, nitrogen oxides and non-methane volatile organic compounds. Their break-down with respect to main activity sectors were shown and their distribution by the largest industrial source categories were worked out as annual estimates. This inventory and its analysis point to serious environmental implications of air pollutants and a need to develop a policy plan for reducing these emissions.
