| This minimizes air exchange, accentuating the effects of wind-borne pollution, and of exterior humidity and abrupt temperature changes. |
|
| This is due to the difficulty in simulating variables such as dirt pickup, air pollution, acid rain, wind-borne particle erosion and mildew. |
|
| But I wonder how many of you have seen the exquisite little red hazel flowers on the same trees waiting quietly to catch the wind-borne pollen. |
|
| But many researchers were not convinced that wind-borne odours could provide the map pigeons need to navigate. |

|
| East Anglia is the worst-affected area of the UK, where it is feared wind-borne spores could have been blown across the sea from mainland Europe. |
|
| You will still get occasional small weed growth within the gravel from wind-borne seeds. |
|
| Some is probably wind-borne, and much of it is carried downriver by seasonal flooding, but most if it is dumped, directly or indirectly, by the inhabitants of York. |
|
| This is rich ground, regularly fertilised by wind-borne shell sand and grazed by cattle, producing an abundance of wild flowers from spring until autumn. |
|
| In general, however, cuticular development is not usually impaired, although the leaf surface may become abraded by the action of wind and wind-borne particles. |
|
| The wind-borne fungus attaches to the leaves of soybean plants and reproduces rapidly, preventing proper plant development and dramatically reduces crop yields if not treated. |
|
| This wind-borne refuse adds to the work of tidying up after storms, but gardeners should do more than just sweep up the mess after the winter gales. |
|
| Botanists believe that silverswords evolved here over millions of years from the wind-borne seeds of the tarweed, a California native with sunflower-like blooms. |
