  • What is a wastewater treatment system and how does it work?

    For industrial companies producing wastewater as part of it’s process, some type of wastewater treatment system is usually necessary to ensure safety precautions and discharge regulations are met. The most appropriate wastewater treatment system will help the facility avoid harming the environment, human health, and a facility’s process or products (especially if the wastewater ...

  • The Key To Controlling Airborne Contamination In Food Processing

    In the food and beverage industry, contamination is always a high priority concern. Small mistakes in handling, preparation, and even in the cleaning of the environment where food comes into contact with surfaces can cause disastrous results that can potentially affect hundreds of thousands of people. Often overlooked is the threat from another source of food contact: air. ...

  • Immunoassays for Environmental Contaminants (Pesticides) in Food and Water

    Immunoassays are one of the most powerful of all immunochemical techniques. They can be employed in a wide range of methods to detect large numbers of different compounds. In this paper, the principles of immunoassay will be explored in general terms. This will be followed by a more specific discussion of the application of these principles to the measurement of pesticide residues in food and ...


  • A risk assessment of the food supply chain: vulnerability against terrorist or criminal contamination

    The food supply chain has been recognised by the USA and the EU as a critical infrastructure, and it should be considered a target for possible terrorist attacks. In this paper, we present a methodological approach developed within the EU project SecuFood to evaluate the risk associated with this threat. The usefulness of the approach is related to the improvement of the analysis of food supply ...

  • Effects on Contaminants And Nutrients on The Dynamics of Different Food Webs in Marine Ecosystems

    During the last decades coastal waters have been exposed to growing anthropogenic pressure represented on the one hand by the increase on the input of nutrients and contaminants and on the other hand by the increased exploitation of these areas for aquaculture, fishing and tourism. Some species might be more sensitive than others, but since the different populations are linked to each other by ...


  • Food contamination after the Chernobyl accident: dose assessments and health effects

    After the Chernobyl accident, a tendency to overestimate its medical consequences was noticed in many scientific publications, a recent example being the volume 1181 of the Annals of the New York Academy of Sciences, entirely dedicated to Chernobyl. In the present paper, several statements from the chapter 'Radioactive Contamination of Food and People' are discussed and their reliability ...

  • SupelMIP SPE for Sample Cleanup and Analysis of Food and Environmental Contaminants

    MIP SPE was successfully used for extraction of multiple classes of food and environmental contaminants from difficult matrices, such as egg, oil and flour. • Six nitroimidazoles were extracted from egg and milk with recoveries typically over 90%. • Among NSAIDs compounds, acidic compounds gave good recoveries between 100-115% while non-acidic compounds gave less desirable recoveries ...

  • Dressing down groundwater contamination

    Unlike the late Paul Newman, who bottled his special-recipe salad dressing and sold it in supermarkets, Dr. Robert Borden simply mixes up his own 'dressing' and pumps it into the ground. That’s because the environmental engineering professor and his graduate students are more interested in feeding microbes to clean up contaminated groundwater than in making just another Ranch dressing. “It’s ...

  • Kick Contamination out of the Cleanroom

    Safety overshoes fight contamination. The steel toecap safety overshoe has been around for a long time. Its origins lie in the marriage between the venerable rubber galosh and a steel toecap similar to those used in many of today’s safety boots. However, the safety overshoe hadn’t evolved much before a slate of revisions entered the market recently. Confined mostly to the “shoes for ...

  • Accumulation of contaminants of emerging concern in food crops, part one: Edible strawberries and lettuce grown in reclaimed water

    Contaminants of emerging concern (CECs) present in domestic waste streams include a highly diverse group of potentially biologically‐active compounds that can be detected at trace levels in wastewater. Concerns about potential uptake into crops arise when reclaimed water is used in food crop production. The present study investigated how nine CECs in reclaimed water are taken up into edible ...

  • The value of utilising stochastic mapping of food distribution networks for understanding risks and tracing contaminant pathways

    Difficulties in adequately characterising food supply chain topologies contribute major uncertainty to risk assessments of the food sector. The capability to trace contaminated foods forward (to consumers) and back (to providers) is needed for rapid recalls during food contamination events. The objective of this work is to develop an approach for risk mitigation that protects us from an attack on ...

  • Effect of reduced food intake on toxicokinetics of halogenated organic contaminants in herring gull (Larus argentatus) chicks

    The aim of the present study was to investigate how contaminant exposure and reduced food intake affect tissue distribution and biotransformation of halogenated organic contaminants (HOCs) in Arctic seabirds using herring gull (Larus argentatus) as a model species. Herring gull chicks were exposed for 44 d to cod liver oil containing a typical mixture of contaminants. Following exposure, food ...

  • Chesapeake Bay fish‐osprey (Pandion haliaetus) food chain: Evaluation of contaminant exposure and genetic damage

    From 2011−2013, a large‐scale ecotoxicological study was conducted in several Chesapeake Bay tributaries (Susquehanna River and flats, the Back, Baltimore Harbor/Patapsco River, Anacostia/ middle Potomac, Elizabeth and James Rivers), and Poplar Island as a mid‐Bay reference site. Osprey (Pandion haliaetus) diet and the transfer of contaminants from fish to osprey eggs were evaluated. The most ...
