Terrestrial Omnivorous/Insectivorous Mammals Sample Clauses

Terrestrial Omnivorous/Insectivorous Mammals. No observed adverse effect level (NOAEL)-based HQs for the white-footed mouse in the Former Wastewater Impoundments are presented in Table 31. The NOAEL-based HQ exceeds unity only for zinc (1.5). No lowest observed adverse effect level (LOAEL)-based HQs exceed unity. Therefore, the risk to the omnivorous / insectivorous mammal feeding guild lies in the risk management area between the NOAEL and LOAEL. The risk was considered marginal and was not recommended for further analysis or risk management. NOAEL-based HQs for the white-footed mouse in the Wastewater Treatment Facility are presented in Table 32. The NOAEL-based HQ exceeds unity only for zinc (1.9). No LOAEL- based HQs exceed unity. Therefore, the risk to the omnivorous/ insectivorous mammal feeding guild lies in the risk management area between the NOAEL and LOAEL. The risk was considered marginal and was not recommended for further analysis or risk management. NOAEL-based HQs for the white-footed mouse in the Current Above Ground Storage Tanks are presented in Table 33. The NOAEL-based HQ exceeds unity only for chromium (1.3), lead (2.1), and zinc (1.7). The HI for HPAHs also exceeds unity (1.5). No LOAEL-based HQs or HIs exceed unity. Therefore, all of the risks to the omnivorous/ insectivorous mammal feeding guild lie in the risk management area between the NOAEL and LOAEL. These risks were considered marginal and were not recommended for further analysis or risk management. NOAEL-based HQs for the white-footed mouse in the Maintenance Shed Area are presented in Table 34. The NOAEL-based HQ exceeds unity only for beta endosulfan (1.7), endrin aldehyde (1.5), and zinc (2.4). No LOAEL-based HQs exceed unity. However, the risk for beta-endosulfan is not bound by a LOAEL due to a lack of available toxicological data. While there is no certainty with where the LAOEL TRV would lie relative to the NOAEL TRV, an assumption that the LOAEL is as little as two times the NOAEL would yield a LOAEL HQ below unity. Of all the TRVs presented in Tables 27 and 28, only two LOAEL TRVs are less than two times the NOAEL TRV, so this assumption is well supported.
