五氯酚对环境污染及居民健康影响研究

中国长期以来使用五氯酚纳盐杀灭亡血吸虫的中间宿主──—钉螺．为评价它对环境的污染及居民健康危害，１９９０－１９９３年在我省开展了五氯酚环境污染及对居民健康影响研究．在研究区采集环境样品（空气、水体、土壤及底泥、蔬菜、肉、蛋、鱼等）共１７３份；生物材料（人血、尿）共４５７份，分析五氯酚浓度．结果在明，在五氯酚使用区，环境中ＰＣＰ浓度稍高于对照区，而生物材料尿、血中ＰＣＰ浓度明显高于对照区．全血胆碱脂酶活性用药区明显低于对照区，统计学分析有显著差异（Ｐ＜０．００１），证实了长期低剂量使用可造成环境及生物蓄积．     

我国北方稻区稻飞虱的成灾机制：一个假说

本文通过对大量文献资料的综合分析，从飞虱的飞行特性和北迁运载气流入手，以东亚大气低层环流为背景审视飞虱在有限时间内远迁北方致灾的成因机制，提出了以北上低空急流的时空变化与南方大发生虫源迁出期（区）相吻合、其前沿所至与北方迁入区相一致作为北方稻虱成灾的启动因子的假说．并提出了验证该假说的研究方法和技术路线，为揭示北方稻虱成灾的奥秘，完善灾变监测技术和预警系统奠定了基础。

利用煮茧废水培养钝顶螺旋藻的初步研究

本文对缫丝厂煮茧废水和Ｚａｒｒｒｏｕｋ培养基的主要营养成份进行了分析比较，筛选出了适合钝顶螺旋藻（Ｓｐｉｒｕｌｉｎａｐｌａｔｅｎｓｉｓ）在煮茧废水中生长繁殖的培养基和与之相适应的驯化藻种。经室外１５０升煮茧废水扩大培养，干藻生物量可达１６．０３克／米￣２·天，粗蛋白含量达５８．６％，含有１７种氨基酸。比用Ｚａｒｒｏｕｋ培养基培养的螺旋藻产量提高１５．７８％，成本减少８０％以上。培养后的煮茧废水ＣＯＤ和ＢＯＤ＿５浓度低于我国污水综合排放标准。研究结果表明：采用本实验室筛选的煮茧废水培养基和驯化藻种，在煮茧废水中大量培养螺旋藻，实现废水资源化是可行的，具有明显的经济效益和环境效益。     

Community opinion concerning airport noise-abatement alternatives

In the present study we examined (1) community opinion of airport noise-abating alternatives and (2) the influence of perceived control on attitudes concerning noise-abatement policies and annoyance toward aircraft noise. We proposed that residents who perceive themselves as having little control over aircraft noise exposure would express higher levels of annoyance than residents who believe they have some degree of control. Furthermore, residents with low levels of perceived control would be less favorable toward proposed noise-abatement alternatives. Survey results collected from 239 households within the 65 CNEL contour of a community airport in Southern California support these hypotheses. Findings indicate strong public support for noise abatement and strong opposition to land-use alternatives. In addition, residents' perceptions of control in the airport planning and management process are significantly related to their annoyance with noise and their opinions about noise management policies.     

DEVELOPMENT OF EARTH SATELLITE TECHNOLOGY FOR THE TELEMETRY OF HYDROLOGIC DATA1

ABSTRACT The use of satellite telemetry is playing a major role in the collection of hydrologic data. Advancing technology and availability of government satellites have permitted many agencies to take advantage of new procedures for acquiring data from automated remote data collection stations. Experiments with Earth satellite technology started in the 1960's and 1970's, with the polar-orbiting National Aeronautics and Space Administration Nimbus and Landsat satellites. Subsequent advancements took place through the development phase to operational systems using the Geostationary Operational Environmental Satellite (GOES) of the National Oceanic and Atmospheric Administration. This satellite system supports more than 2,500 active telemetry sites, of which approximately 1,200 are Geological Survey stream-gaging stations for the collection of hydrologic data. A satellite data collection system is made up of three primary components; a small battery-operated radio, and Earth-orbiting satellite, and an Earth receive and data processing station. The data relay satellites' vast aerial view of the Earth's surface gives satellite telemetry a large advantage over ground-based systems for the collection of real-time hydrologic data for flood warning, reservoir management, irrigation water control, hydropower generation, and the operation of hydrologic stations.     

PHOSPHORUS MANAGEMENT TO PROTECT LAKE WATER QUALITY1

ABSTRACT: The Hallett Quarry gravel pit lakes are an active sand and gravel extraction operation located 0.4 km north of the City of Ames, Iowa. During periods of drought, these lakes serve as a supplemental water supply for Ames. A modified version of the Vollenweider input-output model was used to predict future water quality under various watershed land use, drainage, and lake configurations. The dominant factor controlling the future water quality of the lakes was found to be the nutrient input. It is recommended that a management plan to protect the future water quality should be oriented towards reducing the sources of phosphorus to the lakes.
