CONCLUSIONS: Although albumin adducts of BO and the benzoquinones reflect exposures to benzene [greater than or equal to] 1 ppm, they would not be useful biomarkers of exposure at ambient levels of benzene, which tend to be < 0.
Research in the ecological chemistry of harvestmen has so far been focused on gonyleptomorph Laniatores, all of which produce a mixture of benzoquinones (at least 37 different molecules), while the chemistry of the defensive secretion is not known for even a single member of the Dyspnoi and is known for only one travunioid, Sclerobunus nondimorphicus Briggs 1971.
