In this analysis the overall mRR for leukemia was 1.54 (95% CI 1.18-2.00), but it is not possible to ascertain if the RR would have been higher in the less-exposed cohorts compared to the more highly exposed cohorts, as reported by Collins and Lineker (2004).
High and significant acute myeloid leukemia risks with positive dose response relationships were identified across study designs, particularly in the "well-conducted" cohort studies and especially in more highly exposed workers in rubber, shoe, and paint industries.
As a result, goes the thinking, people living near the proposed route were probably more highly exposed to a kind of costs-benefits trade-off — one that pits potential local jobs from building the pipeline (granted, the actual number that would be created has sometimes been overblown) against ecological consequences.
Either way, this provocative study suggests we are more highly exposed than was previously appreciated.
These populations likely have more highly exposed individuals than the population at large.
These women were younger and more highly exposed than the full cohort (Eskenazi et al. 2004).
Studies in more highly exposed populations have examined urinary As species and As-induced skin pathologies.
These alterations further enhanced the accessibility of enzymes to cellulose, as cellulose surfaces became more highly exposed.
More highly exposed women had babies estimated to average 113.1 g (about 4 oz) lighter than those of unexposed mothers.
If PCBs have a causal relationship with liver cancer one would expect more cancer in a more highly exposed population.
Rural central Africans are more highly exposed to microorganisms present in nonhuman primates than was previously considered.
