  • Hydrodynamics - Natural Water Bodies

    The knowledge of the characteristics of the fluids and their ability to transport substances and physical properties is relevant for us. However, the quantification of the movements of fluids is a complex task, and when considering natural flows, occurring in large scales (rivers, lakes, oceans), this complexity is evidenced. This book presents conclusions about different aspects of flows in ...

  • European water policies and human health — Combining reported environmental information

    Society depends on the satisfactory and sustainable management of water. Historically, the primary purpose of water treatment was to protect human health, through reducing disease being transmitted through water. Subsequent measures to address environmental concerns have broadened our expectations of what water and waste water treatment should deliver. This report considers three pieces of EU ...

  • Algae Control in Lakes and Reservoirs

    There are plenty of harmful algal bloom related cases worldwide but what is evident is that their number elevates with each year. Excessive cyanobacteria (blue-green algae) and green algae growth in a water reservoir can have negative consequences for the water quality. The water turns green, sand filters can clog, and some algae can produce geosmins and MIB, giving the water an ...

  • Frostbite And Hypothermia Hazards

    Hypothermia and frostbite can be two of the serious consequences of working outdoors in winter weather. Hypothermia is a dangerous lowering of the body’s temperature by exposure to cold or wet conditions. Actually, the air temperature doesn’t have to be particularly low to cause hypothermia – just getting wet and chilled can do the same thing. Hypothermia can be fatal. ...

  • Use of Water Based Paint To Reduce Solvent Emissions: Brisbane Motor Bodies

     Background For the last twelve months Richard Powell has been using water based 'base coat' paints in his smash repair business at Woolloongabba. These paints use water, instead of solvent, as the carrier for the basic paint constituents, and do not release any harmful vapours to the atmosphere. Richard has been in the smash repair business for more than twenty five years and ...


  • Effects of 17β‐estradiol on emissions of greenhouse gases in simulative natural water body

    Environmental estrogens (EEs) are widely spread across the world and becoming more and more seriously contaminating. This paper studies the influence of different concentrations of 17β‐estradiol (E2) on the emissions of main greenhouse gases (CO2, CH4 and N2O) in simulative systems in order to explore the relationship between EEs pollution and greenhouse gases emissions in natural water bodies ...

  • TFA from HFO‐1234yf: Accumulation and aquatic risk in terminal water bodies

    A next‐generation mobile automobile air‐conditioning (MAC) refrigerant, HFO‐1234yf (CF3CF = CH2), is being developed with improved environmental characteristics. In the atmosphere, it ultimately forms trifluoroacetic acid (TFA(A); CF3COOH), which is subsequently scavenged by precipitation and deposited on land and water as trifluoroacetate (TFA; CF3COO‐). Trifluoroacetate is environmentally ...

  • Diatoms for assessing the ecological condition of inland freshwater bodies

    The ecological responses of diatoms to pollution and nutrient enrichment, caused by domestic and municipal sewage, in the five fresh water ponds have been examined. It was observed that diatoms were completely absent in P3 and some species were also absent in P1 and P2. Similarly, diatom diversity was lower in P1 and P2 than in P4 and P5. However, diatom abundance was higher in P4. The Biological ...

  • The relationship between wastewater treatment plants and nutrient impaired surface water bodies in seven northern states

    Discharges from wastewater treatment plants (WWTPs) contribute significantly to nutrient loading of surface water bodies and to water body impairments in specific systems. As a result attention has been focused on the control of discharges from these point sources. However, the relationship between nutrient impairment and WWTP discharge on a broader scale is unclear. To investigate this ...

  • Assessing UV- and fluorescence-based metrics as disinfection byproduct precursor surrogate parameters in a water body influenced by a heavy rainfall event

    Although disinfection byproducts (DBPs) were discovered decades ago and surrogate parameters have been developed to track their precursors, the accuracy of these metrics in waters impacted by heavy rainfall events is largely unknown. We measured DBPs and their precursor surrogate parameters in a water body impacted by 28 cm of rain between 4/24/11 and 4/26/11. Raw waters collected from four ...
