Studying these factors as a way of evaluating the health of a body of water is called biological assessment. Biological criteria, on the other hand, are a way of describing the qualities that must be present to support a desired condition in a waterbody, and they serve as the standard against which assessment results are compared.

In order to more easily evaluate sediment contaminated with toxic chemicals, we have established some guidelines to determine ecological risk. About the Guidelines These guidelines, based on different evaluation methods, help us to decide whether a certain amount of toxic chemicals (level of toxicity) is likely to harm the ecosystem.

DIESE : Determination of pertinent Indicators for Environmental monitoring: a Strategy for Europe > Presentation > Partners > People ... > Topical issues European Regional Development Funds : The European Union, investing in your future Created by Véronique Eudes Adapted by Christian Dang Presentation: DIESE is a 4.5-years project financed by the European Interreg IVa France (Channel) / England programme and the French ONEMA , the office national de l'eau et des milieux aquatiques. This project is a collaborative effort to determine the identities, levels and effects of key pollutants in aquatic environments. Endocrine disrupters, carcinogenic and immunotoxic compounds are dramatically affecting the life of many aquatic organisms. All these chemicals are not treated by water treatment plants and thus suffuse widely within waters, inducing sex alteration, cancers or weakening the immune system. Considering these compounds and their many mechanisms of action will improve our knowledge of the biological complexity and the multifactorial effects of mixture of pollutants on aquatic wildlife. The scientific knowledge that will result from this project is expected to become a standard in aquatic environment health assessment and will be disseminated and shared with regulatory agencies, industry and the general public in order to standardise regulatory actions, improve the environmental management and help European citizen to ensure a sustainable development of the region.

Accessibility Skip to Content About Us Prospective Students ... Toxins Natural Toxins Freshwater PSPs DSPs Mycotoxins ... Research Facilities Natural Toxins Background Toxic compounds present in food and water are often associated with a bacterial or chemical contamination. In many cases this is true however another important source of toxins in our food and water supplies comes from nature itself. These toxins can be derived from sources such as plants, fungi and algae and can cause symptoms ranging from mild food poisoning to death. Research within The Institute of Agri-Food and Land Use on Natural Toxins The major themes of natural toxin research within the Institute centre on phycotoxins and mycotoxins. The development of novel and innovative means of detecting the presence of a range of these toxic substances within food and water samples utilising biosensor based technologies has played an important part of the research in recent years. Marine Toxins Toxins secreted by algae and which concentrate in shellfish are a major hazard to the consumer and can bring huge economic losses to the aquaculture industry. The existence of many of these toxins has been known for some time and testing procedures using animal bioassays became the standard means of monitoring for their presence. However due to serious concerns with regards to the effectiveness of these procedures and the use of animal based bioassays which cause enormous suffering to the animals alternative means of monitoring have been sought for several years.

Introduction The radiation physics and radiocarbon research laboratory specialises in the measurement of minute traces of artificial and natural radionuclides in the environment. The laboratory is equipped with state-of-the-art facilities for high resolution alpha spectrometry, low-level beta spectrometry, and high resolution gamma and x-ray spectrometry. Advanced radiochemical separation techniques for nuclides such as plutonium, uranium, thorium, americium, technetium, radiostrontium and radiocaesium have been developed. We also apply radiometric dating techniques for reconstructing environmental histories. Current Research Programmes 1. Marine Radioecology Consequences of radioactive contamination of Arctic waters Transport of contaminated sediments in estuarine and coastal waters (Irish Sea, NE Atlantic, Seine and Gironde estuaries) Solid speciation of radionuclides in fine-grained sediments Ocean scavenging processes using Th/ U disequilibrium 2.
