Little success has been achieved in isolating B. dermatitidis from soil, especially without a potential common exposure site (10).
MnBP, MiBP, and monobenzyl phthalate (MBzP) concentrations were also correlated (r-values ranged from 0.42 to 0.63), suggesting potential common exposure sources.
Furthermore, the correlation between the serum concentrations of PFOS and PFOA was higher than correlations of PFHxS and either PFOA or PFOS, suggesting potential common exposure path-way(s) for PFOA and PFOS, but probably not for PFHxS (mostly used in carpet-treatment applications (Olsen et al. 2004b).
This suggested potential common sources of exposure for the different parabens known to be used in combination in personal care products, pharmaceutical preparations, or food [ 15, 16].
These findings suggest a potential common source(s) of exposure for EP and BP, which was not the case for MP and PP.
Analysis-related inputs include the last date of community exposure to potential common sources of infection, the last date of observation, and inputs for R 0 estimation (mean number of residents per household and mean number of out-of-residence contacts per person per day).
Our findings may have implications for school personnel, particularly those in economically disadvantaged communities, who are concerned about this common exposure and its potential impact on adolescents' respiratory health and should be used to address existing racial and economic disparities in exposure to environmental health hazards.
Ignoring batch effects (our assays were designed to minimize batch effects), potential common environmental effects include stress, diet, and exposure to toxins, pathogens, radiation and chemicals.
Use of the estimated average daily inhaled dose of PM2.5 as the common exposure metric to plot the exposure response relationship as well as the potential for systematic measurement error in PM2.5 exposure estimates could result in scaling distortions.
A food-exposure analysis for the first 10 patients did not identify a potential common food source, so a food survey was not performed for subsequent cases.
Epidemiologic investigation revealed exposure to several potential sources of infection, such as waste management, air conditioners, plumbing, mining, and swimming pools; however, no common exposure could be identified, so environmental sampling and testing were not performed.
