“…The estimation of NOECs to avoid behavioral effects is relevant from an ecological viewpoint, as toxicants can alter the behavior of snails, for example, the feeding activity, time to start normal movement, and ability to avoid polluted conditions, retract their foot, and close their operculum (Burris et al 1990; this study). All these factors affect ecological interactions of animals (e.g., ability to avoid predation) and individual fitness-related traits (e.g., growth rate and reproduction).…”

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.

“…Presence of Snails ( E M ) in Upper Bear Creek Studies conducted in Bear Creek during December 1986 and January and Februaq 1987 showed that EZimia (a snail that is abundant in many streams on the Oak Ridge Reservation) moved downstream when placed into the water near BCK 12.36 (Burris et al 1990). At that time, EZimia was not present in mainstem segments of Bear Creek upstream of BCK 9.4, but was present farther downstream (e.g., near BCK 3.25) and in several north-flowing tributaries (e.g., ST2 …”

“…Pleurocerid (gill-breathing) snails are key grazers and influential competitors in many streams (Hawkins and Furnish 1987, Burris et al 1990, Hill 1992, Stewart et al 1993. These animals can occur in high densities, sometimes comprising more than 90% of the macroinvertebrate biomass (Hawkins andFurnish 1987, Elwood et al 1981).…”

“…Snails respond behaviorally to differences in water quality. when toxicants are present, for example, they may cease feeding, slough their tentacles or retract their foot, or actively attempt to avoid the conditions by moving downstream or crawling out of the water (Burris et al 1990, Harry and Aldrich 1963, Arthur and Leonard 1970, Winger et al 1984, Burris 1987 In the laboratory, the snails were held in 12-L aquaria supplied with a constant flow of dechlorinated tap water. They were fed lettuce ad libitum and acclimated stepwise from the temperature at collection to the testing temperature (25°C).…”

“…The low ammonium release rates, negligible growth rates, poor shell biomineralization, and gross movement patterns (downstream rather than upstream; see Burris et al 1990) of EZimia and Pleurocera in McCoy Branch suggested that the snails were under physiological stress. As a logical outgrowth of the tag-release-recapture test, and with consideration given to information about the kinds of contaminants likely to be present in coal-ash, two hypotheses were formulated:…”

Thii report has been reproduced directly from the best available copy.AvallaMe to DOE and DOE contractors from the Office of Scientific and Techni. yearly ratio of energy derived from gas compared to that from coal is approximately 5 to 1; a higher percentage of coal was used in winter months. A dry vacuum system was installed in May 1990 to collect dry fly ash. Fly ash is now transported to a landfill, and all sluice water discharge to Rogers Quarry has been terminated. By January 1994, a bottom ash dewatering system was installed and functional at the steam plant. The wet bottom ash is sent through the system and the ash residue is trucked to a landfill. The wash down water generated by this process is recycled in the system for future wash down use. The last actual discharge of wet bottom ash to Rogers Quarry occurred in July 1993. CONTENTS (continued)APPENDIX Biological Monitoring Program LIST OF FIGURES Biological Monitoring ProgramPrevious biological monitoring of McCoy Branch was conducted from 1989 through 1990 and included evaluations of instream toxicity, bioaccumulation (in Rogers Quarry), fish community, and benthic community parameters @yon et al. 1992). This biomonitoring indicated that McCoy Branch was receiving low to moderate stress. The instream toxicity studies produced only limited effects on fathead minnow and Ceriodaphnia survival and fecundity in 7-d laboratory tests. In situ snail studies indicated that more stress was seen below Rogers Quarry than above it. Bioaccumulation studies indicated that selenium, arsenic, and possibly thallium were elevated in largemouth bass from the quarry in comparison to levels in reference fish. These fish also had severe deformities present in bony structures.Similar deformities in fish from the stream proper were noticed by the fish community studies in McCoy Branch below the quarry. A fish community was absent in McCoy Branch above the quarry, while the stream immediately below the quarry had an atypical community for a small stream with many species tolerant of degraded conditions. The benthic macroinvertebrate community assessment indicated the maximum impacts were above the quarry, with all sites showing more impact than companion reference sites. Some temporal recovery was noted in the benthic community above the quarry, which was not seen at downstream sites. Overall, McCoy Branch demonstrated moderate impacts on the biological communities, with perhaps some improvement since the cessation .of fly ash disposal. If the system is beginning to recover, then the additional biomonitoring covered in this report should detect further improvement in the above areas. WAWR QUALITYThe water quality data show that although some metal concentrations, levels of radioactivity, and organic constituents are still above reference values, the average values of these contaminants in surface water and groundwater samples in McCoy Branch watershed generally have been decreasing yearly since 1988. During this period, nitrate-nitrogen values have actually fallen b...
