On 10 June 2011, the US National Toxicology Program described formaldehyde as "known to be a human carcinogen". However, formaldehyde is not just a human carcinogen but the cause of other many hazards; respiratory distress, red eyes, etc. Occupational health authorities throughout the world are therefore likely to increase the strictness of regulations for the use of formaldehyde within anatomi...

this paper reports on formaldehyde exposure and its health hazards in a melamine manufacturing industry. the mean of workers' exposure was measured according to 3500 njosh and was found to be 1.44±o.2l, and 2. 17±o.24 ppm in morning and evening shifts, respectively. for stationary ones it was 1.37±o.20, and 2.06±o.25ppm, respectively. the results show that formaldehyde concentration at the...

Formaldehyde is extremely toxic reacting with proteins to crosslinks peptide chains. Formaldehyde is a metabolic product in many enzymatic reactions and the question of how these enzymes are protected from the formaldehyde that is generated has largely remained unanswered. Early experiments from our laboratory showed that two liver mitochondrial enzymes, dimethylglycine dehydrogenase (DMGDH) an...

Several techniques have been used for sand production control in sandstone reservoirs.The main objective of this research is to present a suitable resin to be used as a consolidation agent in oil reservoirs. To achieve this purpose, urea-formaldehyde resin, phenol-formaldehyde resin, and modified urea-formaldehyde resin were selected to be studied. Core samples were made by the sand sample prov...

UNLABELLED Chronic human exposure to formaldehyde is significantly increased by indoor sources. However, information is lacking on why these exposures appear to persist in older homes with aging sources. We use data from the Relationships of Indoor, Outdoor, and Personal Air study to evaluate 179 residences, most of which were older than 5 years. We assess the dependence of indoor formaldehyde ...

This paper discusses the issues of measuring formaldehyde on rich burn natural gas engines typically used in the gas compression industry in the United States. Recently, the EPA passed the final rule for reciprocating internal combustion engines to meet the national emission standards for hazardous air pollutants (i.e. RICE NESHAP rule) for both compression ignition (CI) and spark ignited (SI) ...

simultaneous exposure of highly-used chemical and physical agents are expected to happen in many occupations. in the present study the impact of simultaneous exposure to noise and formaldehyde on oxidative stress in blood and liver tissue of rat was investigated. animal study was conducted in the school of public health, shahid beheshti university of medical scineces, tehran, iran in 2013. a to...

BACKGROUND Formaldehyde can induce misfolding and aggregation of Tau protein and β amyloid protein, which are characteristic pathological features of Alzheimer's disease (AD). An increase in endogenous formaldehyde concentration in the brain is closely related to dementia in aging people. Therefore, the discovery of effective drugs to counteract the adverse impact of formaldehyde on neuronal ce...
