Acute toxicity of inhaled plutonium oxide -238 and -239 in rats Download PDF EPUB FB2

In rats that chronically inhale poorly soluble particles of low acute toxicity, e.g., titanium dioxide, lesions with chronic inflammation, epithelial hyperplasia, and fibrosis often persist or progress after cessation of exposure. For example, less inhaled plutonium is deposited in tobacco smoke-exposed rats than in nonexposed rats.

Human occupational experience clearly indicates that, when inhaled, chromium compounds are respiratory tract irritants, resulting in airway irritation, airway obstruction, and lung, nasal, or sinus cancer. Dose, exposure duration, and the specific compound involved can determine chromium's adverse health effects.

40 Risks to Military Personnel from Exposure to Depleted Uranium Inhalation Exposure Comparisons of renal burdens due to acute ingestion and acute inhalation show that inhaled uranium compounds generally result in higher burdens in the kidneys than ingestion of the same amount of uranium compounds (Chen et al.

McClinton, Jack Shubert, and Argonne National Laboratory. Iodine is an essential trace element. Chemically, iodine is the least reactive of the halogens, and the most electropositive halogen after r, iodine does not occur in the free state in nature. As with all other halogens, when freed from its compounds iodine forms diatomic molecules (I2).

Iodine and its compounds are primarily used in medicine, photography, and dyes. Manganese(IV) oxide was used in the original type of dry cell battery as an electron acceptor from zinc, and is the blackish material in carbon–zinc type flashlight cells.

The manganese dioxide is reduced to the manganese oxide-hydroxide MnO(OH) during discharging, preventing the formation of hydrogen at the anode of the battery. Nitric oxide (nitrogen oxide, [3] nitrogen monoxide) is a molecular, chemical compound with chemical formula of N O that is a colorless gas under standard conditions.

Nitric oxide. Reactions. When exposed to oxygen, nitric oxide is converted into nitrogen dioxide. 2 NO + O 2 → 2 NO 2 This conversion has been speculated as occurring via the ONOONO intermedi. Chemicals that cause damage to target organs (liver, lungs, reproductive system, etc.) if inhaled, ingested, or absorbed through the skin.

Toxic chemicals have an LD50 of 50 - mg/kg, single oral dose for rats. Highly toxic chemicals have an LD50 of rats. The second edition of the Encyclopedia of Toxicology continues its comprehensive survey of new edition continues to present entries devoted to key concepts and specific chemicals. There has been an increase in entries devoted to international organizations and well-known toxic-related incidents such as Love Canal and Chernobyl.The document updates the Health Assessment Document for Chromium by addressing issues regarding noncarcinogenic health effects of chromium: oxidation states and persistence of these states in the environment, sampling and analytical methodology to differentiate these oxidation states and amounts at submicrogram ambient air levels, the degree of human exposure to chromium in the.

Acute and Short-Term Toxicity (or Exposure) Animal In rats and mice the oral LD50 of isotretinoin is mg kgÀ 1 ; in rabbits it is B mg kgÀ 1. Human Overdosage can produce headache or abdominal pain, vomiting, dizziness, irregular muscular coordination, facial flushing, or drying and cracking of the lips, but all symptoms pass.
