They undergo explosive population growths and produce extremely dense concentrations in the ocean called blooms, he said.

Large concentrations of humans produce large concentrations of waste.

A. flavus growth on spices produce low concentrations of aflatoxin as long as the spices remain dry.

In terms of environmental remediation, biosorption is preferable to bioaccumulation because it occurs at a faster rate and can produce higher concentrations.

The results showed that some ozone generators, when run at a high setting with interior doors closed, would frequently produce concentrations of 0.20 - 0.30 ppm.

Some ozone generator manufacturers are claiming their ozone generators produce 'stable' concentrations of O8 or higher.

But even older monitors that were left running continuously for 183 days produced concentrations of the gas that were 10 times higher than office background levels.

Such wastes, when mixed with air and water, produce low concentrations of sulfuric acid, known as acid mine drainage.

Some nonbiological chemical reactions are also known to produce concentrations of light carbon.

Let's begin by asking what method we ourselves would use to produce intense local concentrations of energy.
