  • 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 ...


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

  • Determining trace amounts of contaminants in water

    Introduction Pesticides, polychlorinated biphenyls (PCBs), and pharmaceuticals are a worldwide contamination problem. Several major US water bodies, such as the Hudson River, St. Lawrence River, Fox River and the Great Lakes have been contaminated with PCBs from industries discharging into these water bodies for decades. For example, from approximately 1947 to 1977, the General Electric ...

  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...

  • What is Probabilistic Food Safety Exposure

    What is Probabilistic Food Safety Exposure Assessment? There are a myriad of chemicals in food products consumed by populations. Each chemical in its own right may not be harmful to the population, but in combination with other chemicals, there may be risk of high levels of exposure to potentially harmful substances. An effective probabilistic exposure assessment needs to handle the ...
