About

Hiroyuki Saito’s research focuses on the occupational health hazards of welding, particularly the exposure of welders to harmful fumes, gases, and ultraviolet radiation (UVR). His major contributions include characterizing the emissions from CO₂ arc welding—a widely used industrial process—and quantifying the risks they pose. In his most cited work (2001, 28 citations), Saito measured the high levels of UVR emitted during welding, linking them to acute injuries like photokeratoconjunctivitis. His 2000 study (27 citations) provided critical data on the concentrations of hazardous substances—including ozone, carbon monoxide, manganese, and hexavalent chromium—at the welder’s breathing zone, using a robotic system for precision. Saito also developed a novel inhalation exposure chamber for animal studies (2000, 2 citations), enabling controlled toxicological experiments on the respiratory effects of welding fumes. His work has directly informed workplace safety standards and protective equipment design, helping to prevent chronic and acute health issues among millions of welders worldwide.
