An expanded cohort study of cancer among benzene-exposed workers in China

TLDR
An expanded cohort study of 74,828 benzene-exposed and 35,805 unexposed workers were followed during 1972 to 1987, based on a previous study in 12 cities in China, and a small increase was observed in total cancer mortality.
Abstract
An expanded cohort study of 74,828 benzene-exposed and 35,805 unexposed workers were followed during 1972 to 1987, based on a previous study in 12 cities in China. A small increase was observed in total cancer mortality among benzene-exposed compared with unexposed Workers (relative risk [RR] = 1-2). Statistically significant excesses were noted for leukemia (RR = 2.3), malignant lymphoma (RR = 4.5), and lung cancer (RR = 1.4). When risks were evaluated by leukemia subtype, only acute myelogenous leukemia was significantly elevated (RR = 3.1), although nonsignificant excesses were also noted for chronic myelogenous leukemia (RR = 2.6) and acute lymphocytic leukemia (RR = 2.3). A significant excess was also found for aplastic anemia. 19 refs., 5 tabs.

TL;DR: Evidence to date generally supports an association between breast cancer and polycyclic aromatic hydrocarbons and polychlorinated biphenyls in conjunction with certain genetic polymorphisms involved in carcinogen activation and steroid hormone metabolism.

Advances in understanding benzene health effects and susceptibility.

TL;DR: Evidence for an association with childhood leukemia is growing, and exposure to benzene can lead to multiple alterations that contribute to the leukemogenic process, indicating a multimodal mechanism of action.

Linking exposure to environmental pollutants with biological effects.

TL;DR: Biological effects of air pollutants appear mainly related to oxidative stress via personal exposure and not to urban background levels, in the present setting.

TL;DR: Using actual air sampling data to estimate individual exposures represents a marked improvement over these previous attempts and emphasizes the importance of conducting industrial hygiene surveys and maintaining historical exposure records.

Leukemia in benzene workers.

TL;DR: Reconstruction of past exposures to benzene at the two locations indicates that in some areas of the plant airborne benzene concentrations rose occasionally to several hundred parts per million (ppm), but that for the most part, employee eight-hour time-weighted averages (TWA) fell within the limits considered permissible at the time of exposure.

Major Sources of Benzene Exposure

TL;DR: Data from EPA's TEAM Study allow us to identify the major sources of exposure to benzene for much of the U.S. population, and these sources turn out to be quite different from what had previously been considered the important sources.
