  • Glyphosate and AMPA in drinking water

    Carcinogenic or not? The broad-spectrum herbicide glyphosate is used all over the world in agriculture. Alongside farming, the chemical is also used for weed-killing in domestic gardens and in public and private spaces kept free from «vegetal invasion», such as railway tracks. Glyphosate has been used since the 1970s in pesticides and was hitherto thought to be harmless at ...

  • How Much Water Is Really Used In Food And Beverage Production?

    People concerned about their water footprint often make an effort to turn the faucet off quickly, take shorter showers, and cut back on watering the lawn. While these efforts are important, they ignore one of the biggest water-use culprits found in virtually every household: food and beverages. The production of food and beverages is a water-intensive process. According to the ...

  • A non-phosphorus water treatment agent in water injection system: inhibiting strontium sulfate and dispersing ferric oxide

    Due to the increasing temperature in water injection system, scales are sediments that are firmly attached on the metal surface in the industrial equipment. These scales, including calcium and ferric oxide precipitations, can cause heat transfer problems. A non-phosphorus water treatment agent APES/AA/AMPS was synthesized by acrylic acid (AA), ammonium allylpolyethoxy sulphate (APES) and ...

  • Accounting for metal bioavailability in assessing water quality: A step change?

    Bioavailability of metals to aquatic organisms can be considered to be a combination of the physicochemical factors governing metal behavior and the specific pathophysiological characteristics of the organism's biological receptor. Effectively this means that a measure of bioavailability will reflect the exposures that organisms in the water column actually “experience”. This is important ...

  • Results of heavy metals and other water quality levels in tap water from Çan sourced from Ağı Dağı (Mt. Ağı) (Çanakkale, Turkey)

    In this study, the concentrations of heavy metals Pb, Cu, Zn, Cd, Ni, Fe, Mn and Cr were determined using an inductively coupled plasma and optical emission spectrophotometer (ICP-OES), and water quality parameters pH, temperature, and conductivity were measured using the YSI 556 MPS water probe. The water samples were collected monthly from five different street tap water points sourced from ...

  • Towards an effective protection of groundwater resources: putting policy into practice with the drinking water protection file

    Groundwater in the Netherlands is a major resource for drinking water. As such it must be carefully monitored and managed. Evaluation of the European Water Framework Directive (EU-WFD) showed that protection of this valuable resource needs improvement. The Drinking Water Protection File identifies necessary measures needed per water abstraction site. The Protection File is part of the Dutch ...

  • Derivation of water quality standards for carbamazepine, metoprolol and metformin and comparison with monitoring data

    Environmental quality standards (EQSs) for three pharmaceuticals in surface water were derived: carbamazepine (epilepsy), metoprolol (heart failure) and metformin (diabetes). During the past years, these pharmaceuticals have been detected frequently in Dutch surface waters. The proposed standards are based on ecotoxicity data from national and European authorisation dossiers and additional ...

  • Treatment of oil–water emulsion from the machinery industry by Fenton's reagent

    An oil–water emulsion from the machinery industry was treated using Fenton's reagent. The objective was to reduce the high chemical oxygen demand (COD) of this waste stream so that it would meet the COD effluent limit of Chinese Standard JS-7740-95. The optimal [H2O2]/[Fe2+] ratio for COD removal was 3. An orthogonal experimental design was developed ...
