In the warmer seasons, although surface waters may remain more or less saturated and even supersaturated, the concentrations are lower.
Scientists are working against the clock to determine whether some bat populations stand a better chance of avoiding the fungus by hibernating in parts of caves where spore concentrations are lower.
As a result, the peak area decreases, and calculated concentrations are lower than the expected values.
In the wells far from pollution (Cluster 3 and Cluster 4), established nitrate concentrations are lower (mostly below the RLV).
In peeper 2, Fe(II) concentrations also increase from the uppermost sample, but Fe(II) concentrations are lower (Fig. 5C).
We hypothesized that fetal folate serum concentrations are lower and placental folate transport is impaired in pregnancies of obese women.
Also, average carbon dioxide concentrations are lower in the summer, when plants are growing and absorbing carbon dioxide, than they are in the winter.
At the end of the incident, their aqueous concentrations are lower than the background concentrations due to their exchange back to the surface.
Maximal blood concentrations are lower for ingested marijuana (Huestis [2007]), and are reached between 1 and 7 hours after consumption (Huestis [2007]; Wolff and Johnston [2014]).
Our results suggest that under conditions relevant to marine oil spills where oil concentrations are lower than 1 mg/L and background bacteria concentrations are lower than 2.73 × 104 cells/ml, degradation of dispersed oil droplets with a mean diameter lower than 100 μm typically occur in two stages.
Skewness values of Ca, K, CO3, and hardness are bigger than the unit which means these parameters positively skewed toward lower concentrations, as can also be confirmed by the fact that their median concentrations are lower than their mean concentrations.
