| Clear correlations can then be made between air pollutant exposure concentrations, respiratory function, and quality of life among asthmatics. |
| The pots were carefully sprayed with pollutant solutions for 2 min and maintained in propagators in the growth cabinet as described above. |
| The southern pollutant buildup has long-range effects, often traveling across Africa, far beyond the main brown cloud of particles. |
| Figures showed that amounts of the pollutant nitrogen dioxide were predicted to exceed allowed annual limits in five areas of the city. |
| In addition to ambient pollutant levels, elemental concentrations within moss tissue may be influenced by the nature of the sample. |
| Such use has not only reduced costs but has also helped thermal power stations and paper mills dispose of fly-ash, a pollutant. |
