Multiple sets of age concentration CSD biomonitoring data that represent the general population at background exposure levels, combined with a population PK model, have the potential to provide information about changes in ongoing exposure and intrinsic elimination kinetics of persistent chemicals.
Unsanitary and sometimes transient conditions associated with drug use put that population at risk for exposure to contaminated fecal matter, health departments say.
Population at risk of exposure.
These expected values were adjusted by the estimated increases in the population at risk of exposure in the two periods.
The estimated population at risk of exposure at these 373 sites was 8,629,750 (mean, 23,136, median, 7,000), which is 0.61% of the total population of the three countries.
Blacksmith Institute trained investigators screened 498 sites in India, Indonesia, and the Philippines, with an estimated population at risk of exposure of approximately 12 million.
Inclusion of an estimated number of unscreened sites increased the estimated population at risk of exposure to 43,629,750, and the total DALYs 3,1) to 4,328,722.
The observed/expected ratios, adjusted by the estimated increase in the population at risk of exposure (ie, 3.0- and 1.7-fold increase in the advertisement and post-advertisement period, respectively), are also shown.
The ratio of advertisement period sales to pre-advertisement sales and the ratio of post-advertisement sales to pre-advertisement sales were calculated as an indicator of the increased number of users (ie, the population at risk of exposure).
The population at risk of exposure to elevated [Rn] in well water in 13 towns of greater Augusta were estimated using similar methods based on interpolated and observed [Rn] exceedance percentages of 786 samples, respectively.
Finally, an estimate of the population at risk of exposure to high U or Rn is provided for the greater Augusta area and also for the state of Maine.
