Abstract: Arizona: Lakes, Ponds, and Canals potential impacts of chemical exposures on aquatic bird species Surface water in metro-Phoenix is contaminated due to urban pollutants, impacts from water reuse, soils, and other human interactions. Harmful contaminant levels, in addition to Nitrate-N, Phosphate- P, temperature, and dissolved O2 may possibly have negative consequences on resident and visiting bird species’ populations. Therefore, we conducted a two-year study of bird use of urban aquatic resources across the metro-Phoenix area, which has raised concerns about the transfer of chemical contaminants from surface water to bird species. The pattern that we see in bird populations in urban aquatic resources appears to be seasonal, with some study sites showing a year-round pattern of use. For highly-used aquatic sites in particular, we report concentrations of water contaminants that may be impacting aquatic bird species. Given that Phoenix is part of the Urban Bird Treaty...
