“…In addition to the 2002 un-ionized ammonia data, a recent study by Mummert et al (2003) reported that a substantially high proportion of samples from the NFSR contained UIA levels above the estimated safe environmental threshold (0.01 mg/L) for juvenile mussel habitats. These samples were also above the mean 96h LC50s (0.10 -0.12 mg/L) for the …”

EXECUTIVE SUMMARYThis four-year instream flow study was initiated to evaluate the hydraulics, habitat, and water quality of the North Fork Shenandoah River, Virginia, during low flow conditions. Virginia Tech in cooperation with the United States Geological Survey (USGS) collected hydraulic, fish habitat, and water quality data throughout the basin during periods of extreme drought in 1999 and 2002.This report summarizes the cumulative results, hydraulic, fish habitat, and water quality conditions in the North Fork Shenandoah River (NFSR). These results were used to establish a stepwise process for implementing aquatic conservation flow management in the NFSR basin and facilitate water use conservation measures at appropriate times during extreme droughts of the future. We applied Several issues may complicate the straightforward adoption and successful implementation of the conservation flow thresholds developed in the study.These represent priority research needs for this basin and include: Nutrient

“…Two days of exposure to the same concentration caused mortality to the crustacean Paracalliope fluviatilis (Hickey and Vickers 1994). Nonionized ammonia concentrations ranging from 0.10 to 0.23 mg/L N-NH 3 caused mortality after 4 days to three species of mollusks (Lampsilis fasciola, L. cardium, and Villosa iris) (Mummert et al 2003;Newton et al 2003). Ammonia also affected the activity of the planarian Polycelis felina, with an EC 10 4-day value of 0.14 (0.11-0.16) mg/L N-NH 3 .…”

Long-Term Effects of Ammonia on the Behavioral Activity of the Aquatic Snail Potamopyrgus antipodarum (Hydrobiidae, Mollusca)

An appropriate approach to assess the effect of toxicants on aquatic animals is to monitor behavioral endpoints, as they are a link between physiological and ecological processes. A group that can be exposed longterm to low toxic concentrations is benthic macroinvertebrates, as their mobility in aquatic ecosystems is relatively limited. Therefore, the study of behavioral long-term effects in this group is suitable from an ecological point of view, as behavioral effects can appear before mortality. During the last decades there has been an increase in ammonia concentrations in freshwater ecosystems, threatening aquatic animals. The present study focuses on the long-term effects (40 days) of nonionized ammonia on the behavioral activity of the aquatic snail Potamopyrgus antipodarum. One control and three ammonia concentrations (0.02, 0.07, and 0.13 mg N-NH 3 /L) were used in triplicate, and the activity of snails (as mean time to start normal movement) and immobility were recorded for each treatment after 0, 10, 20, 30, and 40 days of continuous exposure to nonionized ammonia. The results show that P. antipodarum presented a high tolerance to lethal long-term effects of nonionized ammonia, as no animal died during the bioassay. However, the behavioral activity of snails was a very sensitivity endpoint, as a mean nonionized ammonia concentration of 0.07 mg N-NH 3 /L affected P.antipodarum. The results are discussed and compared with the available literature on long-term effects of ammonia on freshwater macroinvertebrates. Additionally, the ammonia water quality criteria, NOECs, LOECs, and long-term LCs are discussed on the basis of the current available data for freshwater macroinvertebrates.

“…Recently, research has found that aquatic organisms, particularly freshwater mussels, are sensitive to chronic exposures to anthropogenic nitrogen inputs (Augsburger et al 2003;Baker and Waight 1994;Bartsch et al 2003;Carmargo and Ward 1995;Mummert et al 2003;Newton et al 2003;Pelley 2003;Rouse et al 1999;Smith et al 1999). Stable nitrogen isotopes (δ 15 N) of organisms are useful measurements to help delineate sources of nitrogen inputs to aquatic environments and to study nitrogen cycling in aquatic systems.…”

Recent biological inventory data shows severe declines in freshwater mussel abundance and biodiversity in the Conasauga River Basin in Northwest Georgia, USA. Based on assessments of habitat conditions, mussel populations should be sustainable. We conducted a study of sediment and water quality to evaluate the impact of anthropogenic contamination on mussel populations. Permeable membrane devices (PMD), polar organic chemical integrative samplers (POCIS), conventional water and sediment quality analyses, and stable nitrogen isotope ratio analyses (delta15N) of snails and sediments were used to assess sediment and water quality at target sites throughout the basin. Ambient concentrations of organic contaminants in water were well below any aquatic life criteria; concentrations of some nutrients were detected above aquatic life criteria levels. Most mussel species in the river are endangered or threatened; therefore, snails were collected for delta15N analyses. Mean delta15N values for snails collected at forested upper watershed sites (national forest areas) were significantly lower than delta15N values from snails in agricultural areas. Delta15N values for raw cow manure and manure-treated soil were similar to delta15N values for snails collected in agricultural areas. Dissolved nitrate from water samples had elevated delta15N values similar to the upper range of delta15N values for snails in agricultural areas. Data, particularly stable nitrogen isotope data, indicates that a land use change from national forest land to agriculture alters nitrogen sources to the basin and snails. Implications of nutrient release on freshwater molluscan reproduction, growth, and survival are discussed.
