The claim is that the ADIs derived for single chemicals signify exposure levels that can be tolerated for a lifetime without harmful effects [ World Health Organization (WHO) 1978].
In gender-stratified analyses, we estimated overall dating violence prevalence (exposure was defined as a response of "yes" to any of the eight dating violence questions in Table 1), and then prevalence of each of the eight dating violence types (response of "yes" to each respective dating violence type signified exposure to that dating violence type).
Here, we provide evidence suggesting that reduced sampling rates does not only signify repeated exposure, but is also a reliable measure of the subjective sense of recollection that accompanies recognition.
Although representing a small portion of total daily activity, time spent outdoors can signify direct exposure to traffic-related pollutants.
Examination of the λmax of Trp compared with [SDS] revealed that Trp residues experienced a red shift towards higher wavelengths (335 339 nm) at SDS concentrations between ∼5 8 mM, signifying the exposure of Trp residues to more polar environments.
Relatively low RBP concentrations were associated with significantly higher DDT and 1,1-dichloro-2,2-bis p-chlorophenyl 1,1-dichloro-2,2-bis p-chlorophenyl 1,1-dichloro-2,2-bis p-chlorophenyl 1,1-dichloro-2,2-bis p-chlorophenyl 1,1-dichloro-2,2-bis p-chlorophenyl
The higher p, p′-DDE concentrations and DDE/DDT ratios observed in the subjects with low RBP status signify long-term exposure to DDT in the group with low RBP concentrations (Ahlborg et al. 1995).
This signifies that post-migration exposures contribute to rather than decrease the burden of preterm birth.
The socio-economic gradient in various measures of health is less marked for women (with the exception of coronary heart disease and body shape) and, rather than being an artifact, this may signify gender differences in exposure or vulnerability.
The high correlations observed among four DEHP metabolites signify a common source of exposure from the parent compound (Silva et al. 2006).
