This page contains the benzene concentration results from laboratory analysis. Analysis is performed on air samples that are collected over a 24-hour period once a week at each community air monitoring station. Additionally, 1 minute grab samples are collected once a week.
For compounds with very low concentration, such as benzene, laboratory analysis often cannot detect the compound. When this occurs, the detection limit will be reported instead. The true value of benzene is below this detection limit. This detection limit can fluctuate based on external factors. Concentrations above the detection limit are much more reliable, and they will be marked in blue on the graph.
The acute 1-hour Reference Exposure Level (REL) for Benzene established by California Office of Environmental Health Hazard Assessment (OEHHA) is 8 ppb. The state-level standard Benzene is also 8 ppb.
Note that laboratory analysis is an extensive process; expect 3 weeks of delay before data is made available. Please use dropdowns above to start displaying data.
