The Absorption of Benzene through Human Skin
International Journal of Occupational and Environmental Health, 2000Abstract : As a result of the proliferation of benzene solutions in several procuction technologies and prolonged exposure poisonings, the question about skin as a way of absorption has re-emerged with respect to the direction of preventive measures and the necessity to clarify the observed clinical signs of absorption.

Absorption of Lawsone Through Human Skin
Cutaneous and Ocular Toxicology, 2007Lawsone (2-hydroxy-1,4-naphthoquinone) is the principal color ingredient in henna, a color additive approved with limitations for coloring hair by the Food and Drug Administration (FDA) under 21 CFR 73.2190. In 2002, the scientific committee on cosmetics and non-food products (SCCNFP), now known as the scientific committee for consumer products (SCCP),

Absorption of hexavalent chromium by skin in man
Archives of Toxicology, 1981Absorption by skin of hexavalent chromium from aqueous solutions of sodium chromate in man was investigated. It was found that the amount of chromium absorbed was related to the concentration of Cr6+ in solution and to time of exposure. For 0.01, 0.1, and 0.2 molar solutions of chromium, skin absorption rates during 1 h exposure were 1.1, 6.5, and 10.0

Skin absorption and human risk assessment
Chemico-Biological Interactions, 2002A common practice is to assume that percutaneous absorption does not significantly contribute to total bioavailability and therefore, absorption through other routes is more important to human risk assessment. The skin can represent a significant barrier to absorption, but some substances are absorbed to a significant extent. Since there is a potential

Absorption of hydrazine through canine skin
Toxicology and Applied Pharmacology, 1972Abstract Hydrazine, in doses of 3–15 mmoles/kg, was applied to the chest of anesthetized male mongrel dogs. Blood samples were withdrawn at intervals and analyzed for plasma glucose and hydrazine contents, for red cell glutathione content and glutathione peroxidase activity.

Absorption of Pesticides in a Chronic Skin Disease
Archives of Environmental Health: An International Journal, 1971The case of a 64-year-old pesticide formulator is presented. Despite the fact that the patient had no more exposure to dieldrin and several other organochlorine pesticides than his occupational associates, and that he used protective clothing, he, nonetheless, developed relatively high levels of these chemicals in his blood and tissues. The high levels

ABSORPTION OF LEAD THROUGH SKIN
Journal of the American Medical Association, 1932To the Editor: —One frequently encounters statements to the effect that lead is not absorbed through the skin. In Queries and Minor Notes (The Journal, June 28, 1930, p. 2086) it was stated, "Lead, however, is not absorbed through the skin, except in the form of substances as tetra-ethyl lead." It is well known that the skin is the least frequent and

Percutaneous absorption in diseased skin: an overview
Journal of Applied Toxicology, 2012ABSTRACTThe stratum corneum's (SC) functions include protection from external hazardous environments, prevention of water loss and regulation of body temperature. While intact skin absorption studies are abundant, studies on compromised skin permeability are less common, although products are often used to treat affected skin. We reviewed literature on

Percutaneous absorption of water in skin: a review
Reviews on Environmental Health, 2014Abstract Background: The stratum corneum has a wide variety of important functions, including host protection from foreign chemicals and bacteria, water loss prevention, and body temperature regulation. While water absorption studies on healthy intact skin are abundant, data on the percutaneous absorption of water in diseased skin are less common.We ...

Percutaneous absorption of vapors in human skin
Cutaneous and Ocular Toxicology, 2010The absorption of vapors through the skin is an important issue because exposure of skin to chemicals in the ambient air occurs at all times. In regards to occupational health, accurately quantifying percutaneous absorption is crucial for worker health and safety.Review the available data regarding the percutaneous absorption of vapors in humans.We ...
