  • Importance of Measuring UV Transmittance for UV Disinfection

    UV disinfection systems disinfect water using UV light at the 254nm wavelegnth. UV light at this wavelegnth actually destroys the DNA of microbiological material in the water which prevents dangerous viruses such as crytosporidium and e-coli from reproducing and causing harm. Real Tech has several products that are commonly used to ensure the correct operation and performance of UV disinfection ...

  • Light Plants and Scene Lighting for Natural Disasters

    According to the Red Cross, the recent onslaught of persistent flooding in Louisiana has surpassed the devastating floods that came with Hurricane Sandy in 2012. Without warning, the state received a whopping 6.9 trillion gallons of rainfall in one week (based on a report from CNN). Over 40,000 homes were affected by the flood, resulting $30 million in damages. Scientists speculate that ...

  • Spatio-temporal variation of groundwater contamination using IEA-UEF in urban areas of Jilin City, North-eastern China

    Groundwater monitoring wells located in urban areas of Jilin City were sampled from 1980 to 2009 for eight groundwater quality parameters: pH, SO42−, Cl−, NO3−-N, NO2− -N, NH4+-N, F−, and total hardness (TH). The data were analysed by a universal exponential formula based on an immune evolutionary ...

  • Monitoring CO2 emissions from new passenger cars and vans in 2014

    The European Environment Agency (EEA) supports the European Commission (EC) and European Union (EU) Member States in the monitoring of the carbon dioxide (CO2) performance of passenger cars, in accordance with Regulation (EC) No 443/2009, and of light commercial vehicles, in accordance with Regulation (EC) No 510/2011. The regulation for passenger cars sets a CO2 emission (1) target of 130 g ...

  • A tiered, integrated biological and chemical monitoring framework for contaminants of emerging concern (CECs) in aquatic ecosystems

    The chemical‐specific risk‐based paradigm that informs monitoring and assessment of environmental contaminants does not apply well to the many thousands of new chemicals that are being introduced into ambient receiving waters. We propose a tiered framework that incorporates bioanalytical screening tools and diagnostic non‐targeted chemical analysis to more effectively monitor for contaminants ...

  • Improved sensitivity to heavy metals in the bioluminescence assay using alternative salt solutions

    Introduction The marine bacterium Vibrio fischeri is widely used for the toxicity assessment of environmental samples. The toxicity is measured in a medium containing 2% NaCl. When the bacteria are exposed to toxic compounds, the light production is inhibited. Toxicity values are obtained after 15 and 30 minutes exposure and expressed as EC50 values, the effective concentration causing 50% loss ...
