WILDLIFE TOXICITY ASSESSMENT FOR PHENANTHRENEResults from these studies indicate that phenanthrene is relatively benign. Given the lack of noticeabletoxic effects of the compound a meaningful TRV cannot be derived. <strong>Phenanthrene</strong> may be regarded as apart of the overall issue of the toxic effects of multiple PAHs on wildlife.2.4 Summary of Avian ToxicologyToxicological data for the effects of phenanthrene on avian species was not located.Ecotoxicological research on the effects of this compound in birds is recommended.2.5 Amphibian ToxicologyToxicological data on the effects of phenanthrene on amphibian species was not located.Ecotoxicological research on the effects of this compound on amphibians is recommended.2.6 Reptilian ToxicologyToxicological data on the effects of phenanthrene on reptilian species was not located.Ecotoxicological research on the effects of this compound on reptiles is recommended.3. RECOMMENDED TOXICITY REFERENCE VALUES3.1 Toxicity Reference Values for Mammals3.1.1 TRVs for ingestion Exposures for the Class MammaliaAt this time it is not possible to derive a TRV for the oral route of exposure for phenanthrene. Nostudies have shown toxicological effects of phenanthrene ingestion.3.1.2 TRVs for Inhalation Exposures for the Class MammaliaNot available at this time3.1.3 TRVs for Dermal Exposures for the Class MammaliaThere is limited data suggesting that phenanthrene will not induce tumors when applied dermally(Roe and Grant 1964). Given these results and the lack of other suitable studies, it is not possible toderive a TRV for dermal exposure at this time.3.2 Toxicity Reference Values for AmphibiansNot available at this time.3.3 Toxicity Reference Values for ReptilesNot available at this time.Page 10 of 14
WILDLIFE TOXICITY ASSESSMENT FOR PHENANTHRENE4. IMPORTANT RESEARCH NEEDSThe limited data available on the toxicity of phenanthrene reflects the need for more researchconcerning the oral, dermal and inhalation routes of exposure. In particular, chronic studies on mammalsare necessary considering the limited data now available. Adequate characterization of the toxicity ofphenanthrene is required before a reliable TRV can be derived. WTA documents on compounds, havingscant information on which to base a TRV, still form a part of the overall risk management process, notonly by identifying research needs but by helping to prioritize the allocation of finite resources inresearch.Page 11 of 14
