  • methyl ethyl
  • The Control of Substances Hazardous to Health (COSHH) Essentials model was evaluated using full-shift exposure measurements of five chemical components in a mixture [acetone, ethylbenzene, methyl ethyl ketone, toluene, and xylenes] at a medium-sized plant producing paint materials. (cdc.gov)
  • soil
  • Methane in the Martian atmosphere and organic chemicals in the red planet's soil are the latest tantalizing findings of NASA's Mars Curiosity rover as it hunts for clues about the possibility of extraterrestrial life, scientists said on Tuesday. (voanews.com)
  • The rover also has found organic chemicals in the Martian soil, the scientists said at a webcast press conference at the American Geophyscial Union conference in San Francisco. (voanews.com)
  • exposure
  • These are exposure studies associated with the chemical and all of its children. (mdibl.org)
  • This study suggests that the prevalence of a cluster of cardiovascular risk factors relates to background exposure to a mixture of persistent organic pollutants, several of which are also related to the prevalence of diabetes. (mdibl.org)
  • The average exposure fractions using the additive mixture formula were also less than unity (batch-making: 0.25, bucket-washing: 0.56) indicating the mixture of chemicals did not exceed the combined occupational exposure limit (OEL). (cdc.gov)
  • The paper version of the COSHH Essentials model was used to calculate a predicted exposure range (PER) for each chemical according to different levels of control. (cdc.gov)
  • The estimated PERs of the tested chemicals for both tasks did not show consistent agreement with exposure measurements when the comparison was made for each control method and this is believed to be because of the considerably different volatilities of the chemicals. (cdc.gov)

  • This study compared three methods of breath sampling for assessment of exposure to volatile organic chemicals. (washington.edu)
  • acetone
  • Eleven healthy volunteers were exposed to four of these five chemicals: ethanol, acetone, methyl isobutyl ketone (MIBK), toluene, and halothane. (washington.edu)
  • exposures
  • Varying levels of control were already established in both tasks and the average exposures of individual chemicals were considerably lower than the regulatory and advisory 8-h standards. (cdc.gov)
