  • Why are we monitoring nutrients at different depths?

    Recently, LG Sonic introduced the MPC-Lab, an innovative monitoring buoy that can monitor algae, physico-chemical variables, and even nutrients such as nitrogen and phosphorus in near real-time and at different depths in a body of water. Combined with our other monitoring tools, this system offers a unique way to detect the spatial and temporal patterns of nutrient concentrations which play a ...

  • Experimental paradigm for in‐laboratory proxy aquatic studies under conditions of static, non–flow‐through chemical exposures

    Endocrine‐disrupting chemicals (EDCs) such as 17α‐ethynylestradiol, 17β‐estradiol, estrone, and para‐nonylphenol have been measured in wastewater‐treatment plant effluents, surface waters, sediments, and sludge and have been shown to induce liver‐specific vitellogenin (vtg) messenger RNA in male fathead minnows (Pimephales promelas). The purpose of the present study was to establish minimal ...

  • Manufacturer of Water Treatment Chemicals and Water Additives

    Water treatment is a process for treating sewage or modern wastewater and converting it into more acceptable form for a specific end-use. The end utilization of this treated water might be drinking, mechanical water supply, water system, waterway stream support, water diversion or numerous different uses, including being securely returned to nature. Water treatment expels ...

  • 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 ...

  • Selecting Appropriate Non-Food Industry Equipment Cleaners

    Non-food industry equipment cleaners are ideal for cleaning heavy-duty industrial equipment and areas, such as floors and walls. These cleaning machines remove grease, carbon black, and many other types of dirt and impurities from metal, vinyl, tile, and similar surfaces. The power and effectiveness of non-food industry equipment cleaners can be attributed to the high pressure level, high ...

  • Treatment performance of a constructed wetland during storm and non-storm events in Korea

    The efficiency of a free water surface flow constructed wetland (CW) in treating agricultural discharges from stream was investigated during storm and non-storm events between April and December, 2009. Physico-chemical and water quality constituents were monitored at five sampling locations along the flow path of the CW. The greatest reduction in pollutant concentration was observed after passing ...

  • Preservation of reverse osmosis membranes with non oxidizing biocides – comparison with SMBS

    Sodium metabisulphite (SMBS) is the current standard preservation chemical used in RO plants during shut down. It is a cheap and efficient preservative, but its tendency to oxidize easily has several drawbacks. The use of a non-oxidizing biocide instead could solve some of the issues currently seen with the SMBS, but little has been reported about membrane compatibility and preservation ...

  • A Citizen`s Guide to Chemical Dehalogenation

    What is chemical dehalogenation? Chemical dehalogenation is a chemical process to remove halogens (usually chlorine) from a chemical contaminant, rendering it less hazardous. Halogens are a class of chemical elements that include chlorine, bromine, iodine, and fluorine. Polychlorinated biphenyls are halogenated compounds that once were used in high voltage electrical transformers because they ...

  • Chemical composition of groundwaters in the Hornsund region, southern Spitsbergen

    Chemical composition of groundwaters was investigated in the region of the Hornsund fjord (southern Spitsbergen). The investigations were conducted during polar expeditions organized by the University of Wroclaw in two summer seasons of 2003 and 2006. Three zones of groundwater circulation: suprapermafrost, intrapermafrost and subpermafrost, were identified in areas of perennial permafrost in ...

  • Isotopic exchange on SPME fiber in sediment under stagnant conditions: Implications for field application of PRC calibration

    An overlooked issue for field application of in situ performance reference compound (PRC) calibration methods is the validity of the assumption that both the sorption of a target compound and desorption of its corresponding PRC follow the first‐order kinetics with the same rate constants under stagnant conditions. In the present study, disposable polydimethylsiloxane fibers of two sizes (7‐ ...
