Introduction This site contains information and resources on a variety of topics related to the growing field of ecological risk analysis. This is an updated and expanded version of the original ORNL site by this name. Whereas the previous version focused on ecological risk assessments for hazardous waste sites (i.e., chemicals), this site now contains information on the expanded role of ecological risk analysis in environmental decision making. All of the tools that made this site popular with risk assessors in the 1990s are still available. However, ORNL has been applying the principles and practices of ecological risk analysis to non-chemical stressors and to environmental management issues other than those typically associated with CERCLA remedial investigations, e.g., military training and testing activities. Information, tools, and other resources are provided for each of these areas below. The information on this site is organized into the following topical areas: Contaminated Sites and the associated ecological risks

69. Neurotoxins Fish Kills Eastern Shore Delaware To Ocean City Maryland Pfiesteria and Chattonella subsalsa aquatic health concerns in cold water climates. http://www.atlanticbreezes.com/aquatic

Dangerous Aquatic Health issues at the beach, ocean, coastal bays and aquatic areas along back bays of Ocean City Maryland and Delaware and other coastal communities. Public awareness of pfiesteria has resulted in bring to light numerous health issues that were previously unknown to occur in our coastal communities. Just as recently as September 29th, 2000 at the North Carolina University (HPLC ULTRA HIGH PRESSURE LIQUID CHROMATOGRAPHY) facility a strain of the Chattonnella micro-organism was isolated and characterized as Chattonella veruculosa. This micro organism behaves similar to Pfiesteria micro toxin, causing fish kills, "red tides", and from empirical evidence being accumulated in Pokomoke Maryland, similar human health effects as pfiesteria. NEW EVIDENCE LINKING ANIMAL MANURES USED AS FERTILIZERS to Pfiesteria and Chattonella dinoflagellates CLiCK HeRE The area of Ocean City Maryland, the back bays of Assawoman Bay, the Bishopville Prong, Sinepuextent Bay, Indian River Bay, Little Indian River Bay, the Delaware River tributaries, and coastal Atlantic resemble many areas to our southern neighbors where the micro-toxin of Chattonnella subsalla exists. The strain of Chattonnella - veruculosa -, analysis just last September has the ability to survive in colder water temperatures. A dinoflagellate, Chattonnella veruculosa, was documented to be in our inland bays and on the Atlantic coastline here in Delaware during the summer of 2000. This organism produces a biotoxin called a breve toxin which affects fish and mammals.

73. Mushroom Poisoning - Wikipedia, The Free Encyclopedia Information from Wikipedia on the deleterious effects from ingestion of toxic substances present in certain fungi. http://en.wikipedia.org/wiki/Mushroom_poisoning

Mushroom poisoning From Wikipedia, the free encyclopedia Jump to: navigation search See also: List of deadly fungi Mushroom poisoning Classification and external resources Amanita phalloides accounts for the majority of fatal mushroom poisonings worldwide. ICD T ICD MeSH Mushroom poisoning , also known as mycetism , refers to harmful effects from ingestion of toxic substances present in a mushroom . These symptoms can vary from slight gastrointestinal discomfort to death . The toxins present are secondary metabolites produced in specific biochemical pathways in the fungal cells. Mushroom poisoning is usually the result of ingestion of wild mushrooms after misidentification of a toxic mushroom as an edible species. The most common reason for this misidentification is close resemblance in terms of colour and general morphology of the toxic mushrooms species with edible species. Even very experienced wild mushroom gatherers are upon rare occasion poisoned by eating toxic species, despite being well aware of the risks, through carelessness. To prevent mushroom poisoning, mushroom gatherers need to be very familiar with the mushrooms they intend to collect as well as with any similar-looking toxic species. In addition, edibility of mushrooms may depend on methods of preparation for cooking. Collectors also need to be well aware that edibility or toxicity of some species varies with geographic location.

74. Laboratory For Radioecology, Nakaminato Studies environmental behavior of radionuclides and effects of radioactivity on marine organisms. http://www.nirs.go.jp/ENG/nakami.htm

Laboratory for Radioecology, Nakaminato Division of Radioecology Division of Marine Radioecology Laboratory for Radioecology, located at Nakaminato, Ibaraki Prefecture, consists of two Divisions (Radioecology and Marine Radioecology) and an Administration Section. Since the establishment of NIRS, the environmental behavior of radionuclides has been one of the main subjects of study. A Division(Radioactive Contamination) at Chiba campus had responsibility for the environmental radioactivity study. In 1968, when planning of a spent fuel reprocessing plant case on schedule, the Institute decided to set up a laboratory to study marine radioecology at Nakaminato. The main aim of study at the laboratory was to obtain values of concentration factors of more important radionuclides for various marine organisms. In 1975, with development of the peacefull use of atomic energy, the Division and the laboratory were amalgamated to form the present organization. The objective of the studies at Nakaminato is to estimate and assess exposure of the population to radionuclides in the various sectors of the human environment, including atmospheric and terrestrial sectors as well as marine sectors. Details of the studies are described under the section of the respective divisions.
