Aniline, The Chemical with 1000 & 1 Uses

This report is written for the dozens of professionals and students who have e-mailed me over the past few years asking questions about the toxicology, uses, and environmental control of the chemical aniline.

The 2000 ACGIH TLV & Current OSHA PEL

The current American Conference of Governmental Industrial Hygienist TLVs(tm) (threshold limit value) for aniline [CAS # 62-53-3] are:

2 ppm Skin toxin. Note: A3 a known carcinogen in animals which may be relevant to humans.

The BEI (Biological Exposure Indices) is 50 mg/g creatinine, 1.5% of hemoglobin, measured as total p-aminophenol in urine and methhemoglobin in blood. These determinants are nonspecific. Blood measurements are subject to background readings and are semi-quantitative, that is only useful as a screening test.

The OSHA PEL (Permissible Exposure Limit) is:

5 ppm [19 mg/m(3)] Skin toxin, according to  Title 29 of the Code of Federal Regulations Subpart Z 1910.1000 TABLE Z-1.

Next “Effects of Exposure”…..
