This case was comparable to some other influenza (H5N1) infections in humans without identified sources of exposure (6, 7 ).
To determine whether environmental levels of phthalates are associated with altered DNA integrity in human sperm, we selected a population without identified sources of exposure to phthalates.
We also procured > 4,000 daily samples of PM2.5 from the Connecticut Department of Energy & Environmental Protection for six cities in Connecticut, which significantly improved both the temporal resolution as well as the geographic relevance of the identified sources of exposure.
School inspections and risk assessments by safety engineers and, if possible, subsequent elimination of identified sources of exposure could pose an appropriate measure to reduce the burden caused by environmental impacts.
Thus, additional exposure studies are necessary, which will in turn assist with understanding the potential burden of exposure globally, identifying sources of exposure, and designing epidemiology studies.
They include identifying sources of exposure, defining unacceptable levels of exposure, developing and testing interventions, and, finally, implementing effective policies and screening programs.
Other than tobacco smoke, we were unable to identify sources of exposure that were statistically significant predictors of U-Cd levels.
Lead isotope ratios (LIR) could be a useful means of identifying sources of exposure for individual cases in routine investigations [ 16].
Additional environmental monitoring data (particularly data collected concurrently with biomonitoring data) would help to identify sources of exposure to better focus future environmental health studies.
Thus, studies of exposure to pesticides among pregnant women are of interest as they will assist with understanding the potential burden of exposure globally, identifying sources of exposure, and designing epidemiology studies.
