  • Biomonitoring can measure what chemical monitoring cannot

    Algae and Daphnia (waterfleas) forewarn drinking water sector Biomonitors, instruments which measure the biological effects of different substances on organisms, detect substances which cannot be detected using chemicals anaylsis methods. This is also valid for combinations of substances which are present in the water in large concentrations. A well-functioning monitor is necessary since our ...

  • On-Line Biomonitors Used as a Tool for Toxicity Reduction Evaluation of in Situ Groundwater Remediation Techniques

    AbstractSuccess of groundwater remediation is typically controlled via snapshot analysis of selected chemical substances or physical parameters. Biological parameters, i.e. ecotoxicological assays, are rarely employed. Hence the aim of the study was to develop a bioassay tool, which allows an on line monitoring of contaminated groundwater, as well as a toxicity reduction evaluation (TRE) of ...

  • Effect of 137Cs gamma radiation on the system bioindicator Tradescantia pallida

    The use of the bioindicator Tradescantia clone 4430 as a biomonitor is limited to a short period of time in regions of hot climate. This paper describes the use of Tradescantia pallida as a bioindicator, to verify its sensitivity to gamma radiation from a 137Cs source and to monitor places of low doses of ionising radiation in tropical climates. Specimens of the T. pallida were exposed to ...

  • Airborne chemical elements: correlation between atmospheric levels and lichen content

    Concentrations of As, Cd, Co, Na, Sb, Se and Zn have been measured in atmospheric particulate matter and Parmelia sulcata Taylor transplants at a suburban and industrial area. Levels in particulate matter were found to be much lower than European target values, Californian Acute Inhalation Reference Exposure Levels and Ontario's Ambient Air Quality Criteria. Correlations between elemental content ...

  • Evaluation of an automated luminescent bacteria assay for in situ aquatic toxicity determination

    A new system for monitoring toxicity TOXcontrol® (MicroLAN BV, The Netherlands) has been used to assess the toxicity of a selection of priority or emergent compounds in the laboratory. In this study, inhibition curves and EC50 – Effective Concentration causing 50% inhibition – of selected compounds (including pesticides, pharmaceuticals, surfactants and metals commonly detected in ...

  • Installation TOXcontrol at River Rhine intake

    The Water works Amsterdam takes surface water from the Rhine at the location Nieuwegein (the Netherlands) for theproduction of drinking water. The water quality of the Rhine can fluctuate due to the input of effluents from SWTP (22million people are living in the catchment area), and due to agricultural and industrial activities along the Rhine. This is why the Water Works Amsterdam operates an ...

  • Cysteine synthesis in Scorpiurum circinatum as a suitable biomarker in air pollution monitoring

    Heavy metals enter ecosystems by both natural and anthropogenic processes. An excess of metals in the environment damages plant metabolism, leading to oxidative stress in the cell. Most metal ions present in the cell are bound to low molecular mass ligands. The major types of S-containing ligands involved in metal binding are derived from cysteine. The authors show, for the first time in ...

  • iTOXcontrol Safeguards Intake Romanian Drinking Water

    The Romanian water supply company Apavital has installed a monitoring station to safeguard the intake of water from the river Prut. The monitoring station is part of an integrated monitoring that signals sudden changes in the water quality of the rivers, enabling Apavital to take appropriate measures, in the worst case a stop of the intake. The iTOXcontrol is developed by the Dutch company ...

  • Better safe than sorry: using the precautionary principle to prevent harm

    Concerned about the increase in disease, declining natural resources and the rate at which some species are becoming extinct, a group of environmentalists, farmers, industry leaders and health care professionals explored solutions. In 1998, they gathered at ...

  • When it comes to food packaging, what we don’t know could hurt us

    Recent analyses raise disturbing questions about the health and environmental effects of the stuff that encases our edibles. It’s almost impossible to imagine life without flexible, transparent and water-resistant food packaging, without plastic sandwich bags, cling film or shelves filled with plastic jars, tubs and tubes, and durable bags and ...

  • What are we doing to our children’s brains?

    Environmental chemicals are wreaking havoc to last a lifetime The numbers are startling. According to the U.S. Centers for Disease Control and Prevention, about 1.8 million more children in the U.S. were diagnosed with developmental disabilities between 2006 and 2008 than a decade earlier. During this time, the prevalence of autism climbed nearly 300 percent, while that of ...
