Personal Exposure among Welders and Non-welders
The objective of this study was to characterize personal exposures to welding-related metals and gases for production welders and non-welders in a large manufacturing facility. Welding fume metals and irritant gases nitrogen dioxide (NO2) and ozone (O3) were sampled for thirty-eight workers. Personal exposure air samples for welding fume metals were collected on 37 mm open face cassettes and ni...
متن کاملLung Health Among Welders
Background: Iron and steel based industries use welding as an integral process. About two percent of the working population is engaged in some type of welding. Welding fumes consist of a wide range of complex metal oxide particles which can be deposited in all regions of the respiratory tract. Thus, welding process seems to be simple but its health implications are complex. Materials and method...
متن کاملGenetic parameters for male fertility and its relationship to skatole and androstenone in Danish Landrace boars.
Concerns have been raised regarding selection against the boar taint compounds, androstenone and skatole, due to potential unfavorable genetic correlations with important male fertility traits (i.e., selection of boars with low levels of these boar taint compounds might also reduce male fertility). Hence, the objective of this investigation was to study the genetic association between direct me...
متن کاملIncidence of cancer among Norwegian boiler welders.
OBJECTIVES The cancer incidence among 2957 boiler welders was investigated. The subjects were registered electrical welders from 1942 to 1981. A subcohort of 606 stainless steel welders was studied separately. METHODS The investigation was a historical prospective cohort study based on a national registry. The loss of follow up was 4.9%. RESULTS There were 625 deaths (659 expected). There w...
متن کاملIncreased male fertility using fertility-related biomarkers
Conventional semen analyses are used to evaluate male factor fertility/infertility in humans and other animals. However, their clinical value remains controversial. Therefore, new tools that more accurately assess male fertility based on sperm function and fertilization mechanism are of interest worldwide. While protein markers in spermatozoa that might help differentiate fertile and infertile ...
