U.S. Army Corps of Engineers TrophicTracee® software was used to predict exposure to avian receptors using measured concentrations of chemicals in sediment, measured concentrations of chemicals in benthic invertebrates, and measured site physicochemical parameters.
The scientists periodically measured concentrations of soot, or particulate air pollution, in each city.
For one thing, no one has ever measured concentrations of antibiotics in nature which are lethal to bacteria.
Researchers have measured concentrations of hazardous ultra-fine particles on the city's arterial roads that are eight times higher than those recorded on rooftop monitors just a kilometre away The health impacts on residents are becoming more and more evident.
The scientists had the women record what they ate each day and measured concentrations of vitamins in their blood.
Measured concentrations of most elements displayed a lognormal distribution.
The acid gas tubes also measured concentrations of NO2.
For each water type, measured concentrations of most elements displayed a lognormal distribution.
Measured concentrations of SPM ranged from 0.68 to 1.92 g L−1.
Hence, each monitor produces uncertainties about measured concentrations of Pb-bearing PM.
In summary blood collection techniques can profoundly alter measured concentrations of AGEs in mother and fetus.
