Validation and uncertainty estimation of analytical method for determination of benzene in beverages.
Styarini D, et al.
Eurasian Journal of Analytical Chemistry, 6(3), 159-172 (2011)
Jelle Vlaanderen et al.
Environmental health perspectives, 119(2), 159-167 (2010-10-01)
The use of occupational cohort studies to assess the association of benzene and lymphoma is complicated by problems with exposure misclassification, outcome classification, and low statistical power. We performed meta-analyses of occupational cohort studies for five different lymphoma categories: Hodgkin
Cliona M McHale et al.
Carcinogenesis, 33(2), 240-252 (2011-12-15)
Benzene causes acute myeloid leukemia and probably other hematological malignancies. As benzene also causes hematotoxicity even in workers exposed to levels below the US permissible occupational exposure limit of 1 part per million, further assessment of the health risks associated
David Galbraith et al.
Critical reviews in toxicology, 40 Suppl 2, 1-46 (2010-10-14)
Over the last century, benzene has been a well-studied chemical, with some acute and chronic exposures being directly associated with observed hematologic effects in humans and animals. Chronic heavy exposures to benzene have also been associated with acute myelogenous leukemia
Deborah C Glass et al.
Occupational and environmental medicine, 71(4), 266-274 (2014-02-18)
Benzene exposure has been associated with increased risk of leukaemia and myelodysplastic syndrome. Existing studies are sparse for other lymphohaematopoietic cancer subtypes, such as myeloproliferative disease (MPD) and the related chronic myeloid leukaemia (CML). We pooled data from three petroleum
