Determinants of temporal variability in NHEXAS-Maryland environmental concentrations, exposures, and biomarkers.
TLDR
The longitudinal NHEXAS-Maryland study measured metals, PAHs, and pesticides in several media to capture temporal variability and provided only modest insight into the factors responsible for the temporal variability in the contaminant levels.Abstract:

Review of the toxicology of chlorpyrifos with an emphasis on human exposure and neurodevelopment.

TL;DR: The results of this review demonstrate that the use of urinary 3,5,6-trichlorpyridinol (TCPy), a metabolite of chlorpyrifos as a biomarker of nonoccupational exposure is problematic and may overestimate non Occupational exposures to chlorparyifos by 10-to 20-fold because of the widespread presence of both TCPy and chlorp Pyrifos-methyl in the food supply.

Cadmium, lead, and other metals in relation to semen quality: human evidence for molybdenum as a male reproductive toxicant.
John D. Meeker,M.G. Rossano,Bridget Protas,Michael P. Diamond,Elizabeth E. Puscheck,Douglas C. Daly,Nigel Paneth,Julia J. Wirth +7 more
TL;DR: These findings represent the first human evidence for an inverse association between Mo and semen quality and are consistent with animal data, but additional human and mechanistic studies are needed.

TL;DR: Pesticides were detected more frequently in house dust, surface wipes, and clothing than other media, with chlorpyrifos, diazinon, chlorthal-dimethyl, and cis- and trans-permethrin detected in 90% to 100% of samples.

Monitoring and Reducing Exposure of Infants to Pollutants in House Dust
John W. Roberts,Lance Wallace,David Camann,Philip Dickey,Steven G. Gilbert,Robert G. Lewis,Tim K. Takaro +6 more
TL;DR: Infants receive their highest exposure to pollutants in dust at home, where they spend the most time, and where the family has the most mitigation control, while recognizing that much remains to be learned about improving the effectiveness of such methods.

The design and analysis of clinical experiments
TL;DR: The Parallel Groups Design as mentioned in this paper is a special case of the Parallel Groups Study, and it is used to control for prognostic variables in linear regression analysis of linear regressions of linear models.

TL;DR: The 24-h time activity patterns of North Americans are remarkably similar and use of the combined data set for some exposure assessments may be feasible.

TL;DR: Blood lead levels continue to decline in the U.S. population, but 890,000 children still have elevated levels, and lead poisoning prevention programs should target high-risk persons, such as children who live in old homes, children of minority groups, and children living in families with low income.
