Pulp and paper production workers have been exposed to a complex mixture of hazardous substances, including known or suspected carcinogens such as wood dust, various wood extracts and associated bioaerosols, reduced sulfur compounds, talc, formaldehyde, combustion products, epichlorohydrin, acid mists, auramine and other benzidine-based dyes, and a range of chlorinated organic compounds (Kauppinen et al.

However, in actual practice, other nonpermitted synthetic dyes like auramine, metanil yellow, lead chromate, rhodamine, sudan-3 and 4, orange-2 and Malachite green, which pose serious health hazards, as they are mutagenic and potential carcinogens, are being used as food colours in the market.

Alternatives to the acid-fast smear include several other stains, such as Ziehl-Neelsen, or fluorochrome staining with auramine or auramine/rhodamine, which may be faster to screen.
