The quantification of diurnal and seasonal gas (NH 3 , H 2 S, and CO 2) and PM 10 concentrations and emission rates (GPCER) from livestock production facilities is indispensable for the development of science‐based setback determination methods and evaluation of improved downwind community air quality resulting from the implementation of gas pollution(More)
Research was conducted from May 2004 through September 2005 to investigate the concentration of hydrogen sulfide (H 2 S) at the perimeter of nine swine operations across the state of Iowa and the ammonia (NH 3) and H 2 S concentrations near and inside residences located in the community of swine operations and in one area of the state not associated with(More)
A Mobile Ambient Laboratory (MAL) was placed at a residence in a community with two swine‐barn emission sites and one land application area to observe real‐time atmospheric stability, ammonia (NH 3) and hydrogen sulfide (H 2 S) concentrations surrounding and within the residence during a 12‐week period. Significant differences in NH 3 and H 2 S(More)
BACKGROUND Floodplain meadows along rivers are semi-natural habitats and depend on regular land use. When used non-intensively, they offer suitable habitats for many plant species including rare ones. Floodplains are hydrologically dynamic ecosystems with both periods of flooding and of dry conditions. In German floodplains, dry periods may increase due to(More)
