For a given pollutant, site, and year, we calculated quarterly mean concentrations based on one of two completeness criteria.
It is possible that concentration-effect relationships could be revealed by repeating the tests at lower concentrations based on less-concentrated stock suspensions.
"Every invertebrate taxon tested had detectable concentrations, based on dry weight, of at least one pharmaceutical in its tissues," the study states.
Raw data were initially measured as relative fluorescence intensities and then converted to cytokine concentrations based on the standard curve generated from reference concentrations supplied by the manufacturer.
Next, predictions for the radical species concentrations based on steady-state and partial equilibrium assumptions were compared to simulation results.
As a first demonstration of multiplexing, Gambhir's team injected mice simultaneously with four kinds of Raman nanoparticles at different concentrations and showed that it is possible to locate the different particles and calculate their concentrations based on their Raman signal.
He noted the inferred sensitivity of climate to a doubling of carbon dioxide concentrations based on this new study, suggesting a rise of 1.2C to 3.9C, was consistent with the range from climate simulations of 2.2C to 4.7C.
As a reference, the dotted lines indicate the growth rates along the c-axes of ice crystals for various AFGP concentrations, based on results of ground experiments (see Supplementary Figure 2).
All lines represent logistic fittings of the concentrations based on Eq. 1.
Superimposed on each diagram are predicted metal concentrations, based on published experimental studies.
