Chromium Toxicity | ATSDR - Environmental Medicine&Environmental Health Education - CSEM
Πέπμτη, 12.18.2008, 01:00pm
  • The toxicity of chromium compounds depends on the oxidation state of the metal.
  • Occupational exposure to chromium(VI) compounds has been associated with increased incidence of lung cancer.
  • Chromium(III) is an essential nutrient that can be toxic in large doses.
Beryllium Toxicity | ATSDR - Environmental Medicine&Environmental Health Education - CSEM
Παρασκευή, 05.23.2008, 01:00pm
  • Beryllium produces health effects ranging from sensitization without evidence of disease to clinically apparent pulmonary disease.
  • Chronic beryllium disease may be misdiagnosed as sarcoidosis.
  • Immunologic tests can detect beryllium sensitization and help clinicians differentiate between chronic beryllium disease and other interstitial lung diseases.
Tetrachloroethylene (PCE) Toxicity | ATSDR - Environmental Medicine&Environmental Health Education - CSEM
Παρασκευή, 05.23.2008, 01:00pm
  • Tetrachloroethylene is used mainly as a solvent for dry cleaning and metal degreasing.
  • Like most chlorinated solvents, tetrachloroethylene can cause central nervous system depression.
  • Chronic exposure to tetrachloroethylene may adversely affect the neurological system, liver, and kidneys.
  • Tetrachloroethylene is reasonably anticipated to be a human carcinogen on the basis of limited evidence from studies in humans and sufficient evidence of carcinogenicity from studies in experimental animals.
Taking an Exposure History | ATSDR - Environmental Medicine&Environmental Health Education - CSEM
Δευτέρα, 05.12.2008, 01:00pm
  • Because many environmental diseases either manifest as common medical problems or have nonspecific symptoms, an exposure history is vital for correct diagnosis.
  • By taking a thorough exposure history, the primary care clinician can play an important role in detecting, treating, and preventing disease due to toxic exposure.
Cadmium Toxicity | ATSDR - Environmental Medicine&Environmental Health Education - CSEM
Δευτέρα, 05.12.2008, 01:00pm
  • Prevention is the key to managing cadmium exposure. No effective treatment for cadmium toxicity exists.
  • For the general public, the primary source of exposure to cadmium is dietary.
  • Smoking tobacco adds an additional burden of cadmium.
  • Nutritional deficiencies can increase the risk of cadmium toxicity.
  • Chronic cadmium exposure primarily affects the kidneys and secondarily the bones.
  • Acute inhalation of fumes containing cadmium affects the lungs.
Trichloroethylne (TCE) Toxicity | ATSDR - Environmental Medicine&Environmental Health Education - CSEM
Πέπμτη, 11.08.2007, 01:00pm
  • Trichloroethylene (TCE) is a common industrial solvent and contaminant of hazardous waste sites, groundwater, and drinking water.
  • TCE is a CNS depressant and a suspected hepatotoxin in humans.
  • TCE is reasonably anticipated to be a human carcinogen based on limited evidence of carcinogenicity from studies in humans and sufficient evidenceof carcinogenicity from studies in experimental animals.
Environmental Triggers of Asthma | ATSDR - Environmental Medicine&Environmental Health Education - CSEM
Τετάρτη, 10.17.2007, 01:00pm
  • Asthma is a chronic inflammatory disease of the airways.
  • Over the past decade, the prevalence of asthma in children and adults has increased in the United States.
  • Environmental exposures to allergens, air pollutants, and environmental tobacco smoke, and workplace exposures can cause and exacerbate asthma.
  • Control of environmental exposures can significantly improve the quality of life of people with asthma.
Cholinesterase Inhibitors, Including Insecticides and Chemical Warfare Nerve Agents | ATSDR - Environmental Medicine&Environmental Health Education - CSEM
Τρίτη, 10.16.2007, 01:00pm
  • Cholinesterase inhibitors are a class of compounds that includes chemical warfare nerve agents and certain insecticides.
  • Fatalities occur mainly due to effects on respiration due depression of respiratory drive, paralysis of muscles of respiration, bronchoconstriction, and airway obstruction from profuse respiratory tract secretions.
  • Treatment includes the use of atropine, 2-PAM, diazepam, and aggressive supportive care.
Ethylene Glycol and Polyethylene Glycol Toxicity | ATSDR - Environmental Medicine&Environmental Health Education - CSEM
Κύριακη, 10.07.2007, 01:00pm
  • Ethylene glycol ingestion first affects the central nervous system (CNS). After a characteristic latent period, signs of inebriation may be followed by serious illness and even death, caused by toxic metabolites.
  • Propylene glycol, which is much less toxic than ethylene glycol, is metabolized to compounds that are normal constituents of the citric acid cycle.
  • No health effects have been reported in persons chronically exposed to ethylene glycol or propylene glycol at levels found in the environment.
Nitrate/Nitrite Toxicity | ATSDR - Environmental Medicine&Environmental Health Education - CSEM
Δευτέρα, 09.24.2007, 01:00pm
  • Nitrate toxicity is a preventable cause of methemoglobinemia.
  • Infants younger than 4 months of age are at particular risk of nitrate toxicity from contaminated well water.
  • The widespread use of nitrate fertilizers increases the risk of well-water contamination in rural areas..
