Work-related asthma: Most frequently reported agents associated with work-related asthma cases by asthma classification, 1993–2006
- indicates no cases ascertained.n.o.s. - not otherwise specified
1 Association of Occupational and Environmental Clinics (AOEC) exposure categories, exposure codes, and agents as of January, 2010. See AOEC exposure code lookup for more information.
2 Substances designated as asthma causing agents by the AOEC as of January 2010.
3 MW - molecular weight, L - low molecular weight (less than 10,000 Daltons), H - high molecular weight (greater than or equal to 10,000 Daltons), U - unable to classify molecular weight, and N/A - not applicable. High and low molecular weight designations presented are not meant to serve as a definitive source of molecular weights for reported agents.
4 “All others within this exposure category” includes exposures associated with less than 10 cases.
5 “All other exposure categories” includes overall categories with less than 10 cases reported. This includes glycols (n=9), organic sulfur compounds (n=9), aliphatic carboxylic acids (n=8), cyanides and nitriles (n=7), ethers (n=7), halogenated aromatic hydrocarbons (n=6), aromatic nitro and amino compounds (n=2), organochlorine insecticides (n=1),and unknown hazard with brand name (n=1).
Note: Each case may be associated with up to three putative agents. Percentages for each state are based on the number of cases reported from California (n=3,529), Massachusetts (n=710), Michigan (n=2,106), and New Jersey (n=417). See Appendix for information about data source and methods.
