Findings on Environmental Research and Public Health Reported by Researchers at Finnish Institute of Occupational Health (Range-finding risk assessment of inhalation exposure to nanodiamonds in a laboratory environment)

By a News Reporter-Staff News Editor at Health & Medicine Week -- Current study results on Environmental Health have been published. According to news reporting out of Helsinki, Finland, by NewsRx editors, research stated, "This study considers fundamental methods in occupational risk assessment of exposure to airborne engineered nanomaterials. We discuss characterization of particle emissions, exposure assessment, hazard assessment with in vitro studies, and risk range characterization using calculated inhaled doses and dose-response translated to humans from in vitro studies."

Our news journalists obtained a quote from the research from the Finnish Institute of Occupational Health, "Here, the methods were utilized to assess workers' risk range of inhalation exposure to nanodiamonds (NDs) during handling and sieving of ND powder. NDs were agglomerated to over 500 nm particles, and mean exposure levels of different work tasks varied from 0.24 to 4.96 gm(-3) (0.08 to 0.74 cm(-3)). In vitro-experiments suggested that ND exposure may cause a risk for activation of inflammatory cascade. However, risk range characterization based on in vitro dose-response was not performed because accurate assessment of delivered (settled) dose on the cells was not possible."

According to the news editors, the research concluded: "Comparison of ND exposure with common pollutants revealed that ND exposure was below 5 ?gm(-3), which is one of the proposed exposure limits for diesel particulate matter, and the workers' calculated dose of NDs during the measurement day was 74 ng which corresponded to 0.02% of the modeled daily (24 h) dose of submicrometer urban air particles."
