Figure AX7-1.3.1. Avian reproduction and growth toxicity data considered in development of the Eco-SSL. Source: U.S. Environmental Protection Agency (2005b). Environmental Protection Agency, 2005b). For more information on the rationale for selecting TRVs, please refer to U.S. Environmental Protection Agency (2003). Many of the toxicity data presented in the Eco-SSL document (U.S. Environmental Protection Agency, 2005b) are lower than those discussed in the 1986 Lead AQCD. The TRV and resulting Eco-SSL were derived using many conservative assumptions. For example, the EPA (U.S. Environmental Protection Agency, 2005b) recognizes that toxicity is observed over a wide range of doses (100 mg Pb/kg bw/day), even when considering only reproductive effects in the same species. In addition, the TRV of 1.63 mg/kg-day is lower than most of the reported doses that have been associated with measured effects. This is true for not only survival, growth, and reproductive effects but also biochemical, behavioral, physiological, and pathological effects, which generally are observed at lower concentrations than effects on growth or reproduction. In addition, the Eco-SSL was back-calculated using conservative modeling assumptions. Therefore, the Eco-SSL of 11 mg/kg may be considered a conservative value. AX7-69
Very little research has been done to expand the knowledge of the toxicity of Pb to birds since the Eco-SSL work was done. However, several studies have been conducted on waterfowl. Toxicity data for waterfowl (in particular, mallards) were included in the soil Eco-SSL development process (Table AX7-1.3.3), although mallards may be more exposed to contaminants in sediment than soil. Effects on waterfowl may vary depending on the form of Pb, characteristics of the sediment, the foraging strategy of the species (which may vary during reproduction), and the nutritional status of the animal. Sediment is recognized as an important route of exposure for waterfowl, particularly those species that dabble (i.e., forage on invertebrates in the sediment) (Beyer et al., 2000; Douglas-Stroebel et al., 2005). Douglas- Stroebel et al. (2005) found that mallard ducklings exposed to Pb-contaminated sediment and a low nutrition diet exhibited more changes in behavior (as measured by time bathing, resting, and feeding) than Pb exposure or low nutrition exposure alone. These effects may be due to the low nutrition diet being deficient in levels of protein, amino acids, calcium, zinc, and other nutrients. Beyer et al. (2000) related blood Pb to sublethal effects in waterfowl along the Coeur d=Alene River near a mining site in Idaho. The authors suggested that 0.20 mg/kg ww blood Pb represents the no-effect level. This no-effect blood concentration corresponds to a sediment Pb concentration of 24 mg/kg. A sediment concentration of 530 mg/kg, associated with a blood Pb concentration of 0.68 mg/kg ww, is suggested to be the lowest-effect concentration. These results are consistent with those of Scheuhammer (1989) who found blood Pb concentrations of 0.18 µg/mL to 0.65 µg/mL in mallards corresponded to conditions associated with greater than normal exposure to Pb, but that that should not be considered Pb poisoning. The study by Beyer et al. (2000) related blood Pb to waterfowl mortality and concluded that some swan mortality may occur at blood Pb levels of 1.9 mg/kg ww, corresponding to a sediment Pb concentration of 1800 mg/kg. Using the mean blood level of 3.6 mg/kg ww from all moribund swans in the study, it was predicted that half of the swans consuming sediment at the 90th percentile rate would die with chronic exposure to sediment concentrations of 3600 mg/kg. Mammalian Consumers Effects on mammals observed in studies conducted since the 1986 Lead AQCD (U.S. Environmental Protection Agency, 1986a) are similar to those reported previously: mortality, effects on reproduction, developmental effects, and changes in growth (U.S. Environmental AX7-70
