Differences in the toxicities of particular congener mixtures may contribute to inconsistent results and make comparisons between studies difficult [ 15], particularly in conjunction with different background levels of exposure.
Near steady-state exposure of healthy adults are probably of minor consequence except for emerging correlations with non-Hodgkin's lymphoma; however, pulses of exposure to more labile mixtures may contribute to developmental effects without leaving a residue record.
It is possible that our method of LPS reduction also removed other allergens from the HDE mixture which may contribute to the allergic response.
New approaches in functional genomics and bioinformatics can help discriminate individual chemicals, or group of chemicals among complex mixtures that may contribute to adverse biological effects (Hook et al. 2014).
Pulses of exposure to more labile mixtures of lower chlorinated PCBs may contribute to transient endocrine disruption, including an increase in estrogenic activity (Hansen 1998; Rose et al. 2002).
Inhalation and dermal contact with technical mixtures of PBDEs in commercial products may contribute substantially to exposure (Sjödin et al. 2004), and several studies in North America have reported dust and indoor exposure to be significant sources of PBDE exposure (Schecter et al. 2005a; Stapleton et al. 2005; Wu et al. 2007).
Certain genotypes may contribute more yield in mixtures than in monoculture; for example, in the four-way mixture experiment, Gy-0 monocultures produced more seed than Ga-0 monocultures yet Ga-0 was the highest yielding genotype in mixtures (Fig. 4A).
It has been suggested that chemicals and complex mixtures capable of modulating the endocrine system may contribute to adverse health, reproduction, and developmental effects in humans and wildlife.
The result of this evaluation was used to determine whether this gene may contribute to the efficiency of the cellulase mixture of Δ wc-1, Δ wc-2 or Δ vvd.
The chemical composition of the particulate mixture also exhibits substantial regional and seasonal variation (Bell et al. 2007); this variation may contribute to the heterogeneity in PM health effect estimates.
Differences in meteorology, the complex mixture of pollution between regions, and the possibility of a threshold effect for ozone [ 48] may contribute to equivocal findings reported in different regions.
