  • Ionising Radiation

    Introduction The energy level of some types of radiation is high enough so that when they interact with matter they cause the formation of electrically charged particles or ion-pairs and break molecular bonds. These so-called ionising radiations are by their nature potentially harmful to life; at high doses they can be lethal and at lower doses can cause genetic damage. Ionising radiation occurs ...

  • Non-Ionising Radiation

    Pressures on the environment may occur through chemical, physical and biological agents. The subject of this study is physical agents, where physical fields are examined. Physical fields are part of the natural environment. Depending upon their properties and the surrounding conditions, physical fields are transmitted through the spaces in which we live, potentially affecting human health and ...

  • Solar/wind power for noise monitoring terminals

    Solar Power Solutions A noise monitoring terminal’s (NMT) low power consumption and its ability to operate fully without power hungry cooling and heating units inside its enclosure mean that it is suitable for power from solar panels. The NMT may be continuously powered by battery which in turn is kept charged via solar energy. This solution is most appropriate in areas where there ...

  • Multi-channel solar ultraviolet radiometer

    Solar ultraviolet radiation: The solar ultraviolet radiation reaching the ground is controlled by several factors, such as solar elevation, cloud cover, total ozone amount and ground reflection. A decrease in total ozone abundance is expected to lead to an increase in harmful UV radiation if all other factors are kept unchanged.  Cloudiness is among the largest sources of variance in the daily ...

  • Vancouver public library green roof monitoring project

    Introduction: Public Works and Government Services Canada (PWGSC) initiated this study to add to the pool of information on Best Management Practices (BMPs) and Low Impact Development (LID) methods. In June 2003, PWGSC partnered with Kerr Wood Leidal Associates Ltd. to conduct a year long monitoring project on the Vancouver Public Library green roof. The purpose of this project is to assess ...

  • Water Quality Monitoring and Testing Using an Environmental Logger

    Intelligent dataTaker System from CAS DataLoggers Water disruptions typically occur after a large amount of water has rapidly collected in a catchment area. As a result this water is subject to continual monitoring and testing for a variety of chemical and biological agents as well as clarity, rate of movement, and water levels for environmental management. Turbidity, conductivity, ...

  • New monitoring technology helps reveal Arctic secrets

    A group of Arctic researchers has employed the latest monitoring technology to investigate the effects of climate change, by measuring temperature and salinity in the water column beneath surface ice. The results of the investigation, which utilised YSI’s new 'Castaway-CTD', could cast new light on our understanding of the ways in which shifting ocean currents impact upon the climate in ...

  • Status of black carbon monitoring in ambient air in Europe

    Black carbon (BC) is increasingly discussed in science and environmental policy areas as an example of an air pollutant that affects both human health and contributes to climate change (e.g. WHO, 2012; UNEP/WMO, 2011; Bond et al., 2013; IPCC, 2013). In order to be able to make comparable measurements of BC in ambient air and to relate BC monitoring to health impacts and climate change it is ...

  • Data assimilation for crop yield and CO2 fixation monitoring in Asia by a photosynthetic sterility model using satellites and meteorological data

    This study assimilates satellite and meteorological data to monitor grain yields and CO2 fixation by developing a photosynthetic-sterility model that integrates the Asian scale of meteorological data such as solar radiation, air temperature effects on photosynthesis and the Normalised Difference Vegetation Index (NDVI) with a Satellite Pour l'Observation de la Terre (SPOT) VEGETATION sensor. ...

  • Variability of PM10 concentrations dependent on meteorological conditions

    The influence of atmospheric exchange conditions on near-surface PM10 concentrations is analysed for four cities in the South-West of Germany in the period from 2001 to 2005. For each city, the PM10 data originates from roadside stations and Urban Background (UB) stations, that is, two types of official urban air quality monitoring stations characterised by different emission situations. The ...

  • The impact of plant water uptake and recharge on groundwater level at a site in the Loess Plateau of China

    Shallow groundwater in unconsolidated sediments represents a substantial water resource in the Chinese Loess Plateau. However, prior to development of the water supply for agriculture, annual and seasonal fluctuation of the recharge mechanism should be clarified. Since the region is arid, the effect of plant water uptake on groundwater fluctuation must also be assessed. A study was therefore ...

  • Baseline data in air quality impact studies

    The main objective of this paper is to explain not only the importance of the baseline data in air quality studies but also the general procedures and steps involved in the baseline data collection. Special considerations on the instruments and measurements for a perfect baseline data collection are also emphasized in this paper. As an example, an adequate baseline data collection procedure which ...
