Bureau of Labor Statistics, 2020).  Many workers in the upstream oil extraction industry have potential risk of crude oil vapor (COV) inhalation.  There are many current knowledge gaps regarding the health effects from inhalation of complex mixtures found in crude oil vapors.  To aid research in filling these gaps, an automated system that could carefully deliver and control the COV concentration within an animal inhalation exposure chamber was needed.  The objective of this project was to develop an automated computer-controlled system to expose small laboratory animals to precise concentrations of crude oil vapor (COV).\", \"distribution\": [{\"@type\": \"dcat:Distribution\", \"downloadURL\": \"https://data.cdc.gov/download/6wqg-8ykc/application/x-zip-compressed\", \"mediaType\": \"application/x-zip-compressed\"}], \"identifier\": \"https://data.cdc.gov/api/views/6wqg-8ykc\", \"issued\": \"2024-11-15\", \"landingPage\": \"https://data.cdc.gov/d/6wqg-8ykc\", \"license\": \"http://opendefinition.org/licenses/odc-odbl/\", \"modified\": \"2026-01-14\", \"programCode\": [\"009:034\"], \"publisher\": {\"@type\": \"org:Organization\", \"name\": \"Centers for Disease Control and Prevention\"}, \"theme\": [\"National Institute for Occupational Safety and Health\"], \"title\": \"Automated oil vapor inhalation exposure system\"}","source_transform":null,"status":"error"}
