OBJECTIVES Sino-nasal cancer has been consistently associated with exposure to wood dust, leather dust, nickel and chromium compounds; for other occupational hazards, the findings are somewhat mixed. The aim of this study was to investigate the risk of sino-nasal epithelial cancer (SNEC) by histological type with prior exposure to suspected occupational risk factors and, in particular, those in...
SEPTEMBER 2006 -s 200 ABSTRACT. The relationship between alloying content, microstructure, and properties has been clarified for highstrength steel weld metals with 7 to 9 wt-% nickel. Neural network modeling suggested that manganese reductions and nickel additions in a controlled manner with respect to manganese lead to increased impact toughness. Carbon additions were predicted to enhance yie...
BACKGROUND To better understand the mechanism(s) of particulate matter (PM) associated cardiovascular effects, research priorities include identifying the responsible PM characteristics. Evidence suggests that metals play a role in the cardiotoxicity of fine PM (PM2.5) and in exposure-related decreases in heart rate variability (HRV). We examined the association between daytime exposure to the ...
<p><em>Welding workers are potentially exposed to cadmium containing fumes during the welding process. Cadmium is one of heavy metals that considered toxic. can interfere with health body organs such as kidneys. Accumulation in kidneys decrease excretory activity veins. Resulting impact an increase uric acid levels (hyperuricemia). This study aims determine relationship between hair...
