The main objective of this study is to investigate the personal or area exposure of organic solvents during paint stripping and paint spraying. Three aircraft paint stripping/spraying workplaces in Taiwan were selected, and the Council of Labor Affairs and NIOSH recommended sampling/analytical methods used in this study. Activated charcoal tubes were used to investigate the personal and area ex...

ead poisoning causes adverse health L effects in adults and children in a dose-dependent fashion. Workplace lead exposures below the current permissible exposure limit (PEL) that result in blood lead levels (BLLs) much lower than those permitted by the US Occupational Safety and Health Administration (OSHA) can cause adverse health effects. To adequately protect American workers, new lead stand...

Several recent demonstrations of the abilities of micro-electromechanical systems (MEMS)-based microsensor technology to detect hazardous ompounds and their simulants in a variety of background conditions are presented. In each case, two pairs of conductometric metal oxide sensors TiO2 and SnO2) produced via chemical vapor deposition are operated using temperature-programmed sensing (TPS). NIST...

Abstract Background Childhood obesity is a major public health concern, especially in low socioeconomic groups. Sedentary time (SED) an important predictor of obesity. To be able to diminish SED it find modifiable predictors sedentary behavior. The home environment associated with children’s may vary by parental status. This study aims clarify the association between educational level (PEL) and...

Extremely strong magnetic fields at the frequencies used in an electromagnetic articulometer (EMA) system may pose a risk to the health of a subject. To avoid such risks, the field strengths produced by any EMA system should be measured, and compared to published permissible exposure standards. This letter reports measurements of the 2-50kHz magnetic field strength of the Carstens Articulograph...

flint) is perhaps the oldest occupational disease, probably existing in the paleolithic period. Hippocrates and Pliny refer to the disorder. Some of the most tragic and wanton examples of occupational disease were due to silicosis, for example, how table blade grinding in Sheffield (1886) robbed workers of 25 years of life, or the Gauley Bridge disaster in West Virginia (1931). Perusing a recen...

aim: this study was conducted to investigate the accumulation of three heavy metals including lead, tin and zinc in the liver and muscle tissues of 60 silver carp (hypophthalmichthys molitrix) collected from different stations of the anzali wetland (located at the west south of caspian sea): pirbazar, anzali, khazarvila, beshman, sangachin and abkenar, in april 2011. materials and methods: samp...
