But while scientists who took part in the current study have identified these obvious "pathways of exposure," it is notoriously difficult to link the pollution to cancer.
"We have studied this thing inside out and continue to do so, and we are not finding contaminants that pose a substantial risk, or pathways of exposure," said Mark Lowery, a department spokesman.
"In my heart I cannot fathom that with the amount of time spent, the amount of money, the amount of cases, the amount of pathways of exposure we have already been told about that we can't find some answers here," said Linda Gillick, whose 22-year-old son Michael suffers from neuroblastoma, the same fast-spreading cancer that Lauren Kotran must deal with.
The sources and pathways of exposure and the health significance of these findings need to be further investigated.
McKenzie et al. [1] concluded that further study of this and other pathways of exposure was required in the US due to the nature of their findings.
The individual pathways of exposure according to EFSA [15] and Fromme et al. [38] are summarized, and the resulting total exposure to PFCs is calculated in Table 11.
These calculations do not include an assessment of non-cancerous health effects or cancerous health effects caused by other pathways of exposure and other chemicals.
State-of-the-science sample collection methods and considerations for the selection of methods used for estimating exposures associated with different routes and pathways of exposure are discussed.
It documents how the pathways of exposure to this toxin/poison have been greatly expanded through intensive application of groundwater in agriculture in the region within the Green Revolution framework.
Here we evaluate what is known about pathways of exposure at the animal-human interface using all available publications, including seroprevalence studies and case-control studies not included in previous reviews, which could result in human infection with H5N1 virus.
Environmental pathways of exposure may be equally important.
