Tracer was consistently detected at elevated concentrations at downwind sampling locations.
Besides iron, manganese is frequently present at elevated concentrations in waters draining both coal and metal mines.
Results from ecotoxicological studies show that certain NP have effects on organisms under environmental conditions, though mostly at elevated concentrations.
Experimental data indicate that the charged stars may form temporary shell interacting (electrostatically stabilized) aggregates at elevated concentrations.
An essential micro-nutrient, Se can prove harmful to fish, water fowl, livestock, and even humans at elevated concentrations.
As demonstrated by comparison of the wild-type, dissociable, and the constantly dimeric FRP variant, monomerization is not mandatory for functional activity of FRP, but may significantly improve its efficiency, especially at elevated concentrations of OCPR.
Nitric oxide is a cell signaling molecule that can be a potent inducer of cell death in cancers at elevated concentrations.
Trace metals can negatively affect external fertilization processes in marine broadcast spawners and may cause a reduction in fertilization success at elevated concentrations.
Existence of glyphosate, the most extensively used non-selective herbicide, in waters at elevated concentrations has received worldwide attention due to its ill consequences.
Binding of Rad51p to dsDNA also requires ATP; ADP is ineffective, whereas ATPgammaS and AMP-PNP are considerably less able to promote binding and only at elevated concentrations of Rad51p.
It was therefore hypothesized that estrogenic organochlorine pesticides, present at elevated concentrations in animals from Lake Apopka, could cause the reproductive disorders in males, as well as increase female fecundity.
