The colonization of limestone bricks and bitumen coated limestone bricks by benthic river organisms was followed over time. After nine weeks of colonization, no massive increase in the numbers of bacteria on the bitumen was noted, suggesting that degradation was not proceeding rapidly. However,...

A climatological air quality dispersion was developed which provides more powerful analyses capabilities than are avaiIable in traditional COM-type models. The model incorporates a time series approach to satisfy identified user needs. The three components of the model are: the time series file...

The colonization of limestone gravel, limestone gravel + organic matter, and limestone gravel from a river bed was followed over time in order to compare two possible stream reclamation substrates with a control (river gravel). After nine weeks of colonization by benthic micro- and...
