Critical review and synthesis of the epidemiologic evidence on formaldehyde exposure and risk of leukemia and other lymphohematopoietic malignancies.

Among the formaldehyde-exposed portion of the cohort, there was a weak trend of relative risk (RR) with peak exposure, for both all leukemias and myeloid leukemia, largely influenced by elevated RRs of 1.78 (95 % CI 0.87–3.64) for myeloid leukemias and 1.42 (0.92–2.18) for “other” (non-myeloid) leukemias in the highest peak exposure category.
