With regard to the term "smoking", the e-cig PV, NI playing field is a minefield that many of us are guilty of creating. That is why they are referred to as "electronic cigarettes" instead of a more accurate and less negative term such as "personal vaporizer" or "nicotine inhaler". Truth be told, these devices are not cigarettes and we should avoid any terms that connect them to analog tobacco. The term "smoking" is an obvious reference to smoke produced by combustion.
B1; probable human carcinogen. Based on limited evidence in humans, and sufficient evidence in animals. Human data include nine studies that show statistically significant associations between site-specific respiratory neoplasms and exposure to formaldehyde or formaldehyde-containing products.
An increased incidence of nasal squamous cell carcinomas was observed in long-term inhalation studies in rats and in mice. The classification is supported by in vitro genotoxicity data and formaldehyde's structural relationships to other carcinogenic aldehydes such as acetaldehyde.
There is limited evidence in humans for the carcinogenicity of formaldehyde. There is sufficient evidence in experimental animals for the carcinogenicity of formaldehyde.
Formaldehyde is probably carcinogenic to humans Group 2A. The Pharmacological Basis of Therapeutics. Toxicology of the Eye. American Conference of Governmental Industrial Hygienists, Symptoms related to inhalation include: The International Technical Information Institute, With higher concn, cough, dysphagia, bronchitis, pneumonia, edema or spasm of the larynx.
Pulmonary edema is uncommon. Difficult micturition, hematuria, anuria. Death due to respiratory failure. Strong solutions produce coagulation necrosis. Clinical Toxicology of Commercial Products. Williams and Wilkins, It can exert a small, across-shift effect on airways but after a mean exposure of 10 yr does not appear to cause permanent respiratory impairment.
The questionnaires were given to a cohort of 1st-yr medical students on completion of the gross anatomy lab course. Air sampling of formaldehyde levels in the anatomy labs was carried out on one day during the time in which these students were conducting dissections. Although the results of the air sampling showed formaldehyde levels to be well below current occupational standards, significant numbers of students reported experiencing symptoms associated with formaldehyde exposure.
Estimates of the relative risk of experiencing formaldehyde-related symptoms in the anatomy laboratories compared to the control laboratories ranged from 2. In addn, it was found that female students were 3 times more likely to report formaldehyde-related symptoms than male students.
Logistic regression was used to estimate exposure odds ratios STET while taking into account multiple risk factors for each site. Several limitations in the study tend to conservatively bias the results. The protocol consisted of randomized exposure of each subject to clean air or 3.
Potential hazardous workplace exposures varied with department and included Mortality from all causes combined was lower than expected for each tannery. Deaths from cancer of each site, including the lung, were also lower than expected compared to those of either the population of the United States or of local state rates.
A significant excess of deaths was observed, however, due to accidental causes in one tannery and cirrhosis of the liver, suicide, and alcoholism in the other. These excesses did not appear to be casually associated with occupational exposures.
The incorporation of labeled thymidine by T-cells phytohemagglutin was decreased: The probable mean lethal adult dose is 1 to 2 oz.
Death may occur within 3 hours; survival past 48 hours usually means recovery. Diagnosis and Treatment of Human Poisoning. Results from both were unremarkable, as were tests mapping their visual fields.Smoking, inhalation and exhalation of the fumes of burning tobacco.
