Consequently the use of population mean perception of exposure as estimates of true exposure may be problematic if there has been significant local media interest in this subject irrespective of any objective measure of pollution.
The Christian population would see this as a humiliating exposure of the true "nature" and inherent weakness of human flesh.
Zhang et al. (2009) claim this is because average and cumulative exposure maybe less accurate measures of true exposure if workers with very high exposure also have long intervening periods with little or no exposure, but they have not considered whether these metrics are relevant for assessing risk.
Nevertheless the amount of excipients in drug formulations is rarely reported in the SPCs making the evaluation of precise exposure and assessment of true harmfulness of these substances to neonates impossible.
The epidemiologic challenges inherent in exploring linkages between chronic OP pesticide exposures and adverse health outcomes may likely be attributable to the collection of exposure data that are not representative of true exposure.
Third, SHS exposure was self-reported which could lead to misclassification of true exposure although positive associations between self-reported SHS exposure and SHS exposure measured by biomarkers were frequently reported.
In the second model we parameterize the probability of "true" exposure, given reported exposure and case/control status, with prior parameter estimates of exposure misclassification (sensitivity and false-positive probability [i.e., 1-specificity]) described below.
Thus, virtually all exposure assessments provide at best estimates of true exposures, with some error.
Therefore, the presence of DAPs in urine can be expected to track relative changes in exposure to OP pesticides, despite providing an overestimate of true exposure.
All water contact measurement tools, including direct water contact observations are only an indirect measure of true exposure, i.e. exposure to infectious cercariae.
