Historical NIOSH estimate; potentially exposed does not mean measured above a limit.
Small occupational study; exposure concentrations were below cited Swedish limits and several U.S. limits, so it is not a population prevalence estimate.
Clinical study group, not a representative workforce sample.
Means from a selected clinical study population; not a national average.
This is a measurement convention, not an observed prevalence or health outcome.
Sampling guidance, not a workforce exposure estimate.
The category includes dust and fumes as well as chemical vapors and gases; estimates are self-reported.

Count reflects identified agents in the cited literature and is not a count of exposed workers.
Wide literature-derived range; work-related asthma includes new-onset and work-aggravated disease.
State surveillance case count; it is not a national incidence estimate.
Surveillance trend across two periods; case ascertainment and exposure patterns may change over time.
State surveillance comparison, not a controlled intervention effect.
Share of reported cases, not exposure prevalence among all cleaners or workers.
Case-series healthcare utilization; it does not estimate risk among all exposed workers.
Application behavior in a surveillance case series; not a measure of eligibility or approval.

Deaths reflect past working conditions and long disease latency; not all causes are chemical.
Disease attribution includes multiple occupational agents and is not chemical-specific.
Occupational attribution is broader than chemical exposure alone.
Asbestos is a workplace exposure, but this is not a general chemical-exposure statistic.
Occupational disease outcome; asbestos is the major historical cause and the figure is not a general chemical prevalence measure.
Labour Force Survey self-reports; the total includes stress, musculoskeletal disorders and other illnesses, not only chemical-related disease.
The HSE page does not isolate chemical causes within this residual category.
LFS self-report rate for all work-related ill health; it is not a chemical-exposure rate.
