Evidence for the paraoccupational exposure pathway
came primarily from residential dust monitoring that compared farm and non-farm homes, or homes of farmers who performed tasks that involved contact with pesticides and homes of farmers not doing those tasks.
Other exposure pathways
that still need evaluation include consumption of garden vegetables grown in contaminated soils; consumption of milk or meat from cows, goats, and chickens that forage in contaminated areas; consumption of breast milk from mothers exposed to contamination; and exposures to particles abraded from adobe bricks made with lead-contaminated wastes.
MDH concluded that there were no complete exposure pathways
and, consequently, that there was no immediate threat to public health (7,8).
The exposure pathway
analysis shown in Table 3 reveals the source of exposure as the solid waste in the uncovered landfill.
The exposure pathways
of interest were inhalation of vapor, inhalation of particles, dermal sorption of DEHP, and oral ingestion of household dust.
Effectively managing MeHg risks therefore requires information on the exposure pathway
at both local and global scales.
2008a) stated recently that dust ingestion is a pertinent exposure pathway
for HBCD, and a significant positive correlation was reported between concentrations of PBDEs in house dust and diet and those in human milk (Wu et al.
Effective policies require cumulative risk assessments that not only provide reliable estimates of cumulative intake but also identify the important sources and exposure pathways
contributing to this intake.
SAIDs (b) (n = 494) Potential occupational exposure to vermiculite Ever work for W.
A set of core individual characteristics was included in each exposure pathway
analysis: maternal age and birthplace, smoking during pregnancy, previous lactation, child's date of birth and sex, dredging period, and household income.
The same authors argued that skeletal sources of Pb accumulated from past exposures should be considered along with current sources when exposure pathways
are being evaluated.
