Chronic Toxicity of Phenanthrene to the Marine Polychaete Worm, Nereis (Neanthes) arenaceodentata

Vallen L. Emery Jr.¹,

Abstract: Polycyclic aromatic hydrocarbons (PAHs) are widely distributed in the environment. While environmental concentrations are generally below acutely lethal levels (Hyland and Schneider 1976), chronic, low level exposures may result in subtle sublethal effects. PAHs accumulate in bottom sediments and may represent a hazard to the benthos. Polychaetes are important members of this community (Officer and Lynch 1989). The objective of this study is to evaluate the chronic sublethal effects of one PAH, phenanthrene (P… Show more

This study examined the suitability for the use of the polychaetous annelid Neanthes arenaceodentata in a short-term sublethal bioassay based on postexposure feeding rate. Quantification of feeding rate was determined by an approximately 1-h feeding period to Artemia franciscana nauplii after a 48-h aqueous exposure. Both lethality and feeding rate were assessed after exposure to Cu and phenanthrene, with the Cu results being compared with those available from similar studies that used the polychaete Hediste diversicolor. Laboratory assessment on the effect of manipulating two common variables in estuarine environments (temperature and salinity) on postexposure feeding to both clean and Cu-spiked seawater samples was also conducted. The 48- and 96-h median lethal concentrations (LC50s) for Cu were 156 and 80 µg/L, respectively, whereas the 48-h median effective concentration (EC50) determined by feeding rate was 57 µg/L. The 48-h LC50 for phenanthrene was 2,224 µg/L, whereas the 48-h feeding rate EC50 was 345 µg/L (more sensitive by a factor of >6). The sensitivity of the postexposure feeding rate endpoint to two representative chemicals that are frequently elevated in contaminated sediments, in addition to rapid exposure time, ecological relevance, and relatively simple approach, suggest that this assay with N. arenaceodentata has potential for use as a tool for sublethal effects assessment, with particular promise for in situ applications. The utility of this assay in actual marine and estuarine sediments is being assessed in situ at several North American sediment sites, and will be reported in future publications.

The chronic toxicity of sediment‐associated 2,4,6‐trinitrotoluene (TNT) to the marine polychaete Neanthes arenaceodentata and the estuarine amphipod Leptocheirus plumulosus was evaluated. Test organisms were exposed to sediments spiked with radiolabeled TNT for 28 d, after which time the endpoints of mortality, growth, and reproduction (L. plumulosus only) were assayed and compared against the TNT tissue concentrations as well as the TNT sediment concentrations. Survival was significantly reduced at a tissue concentration of 61 μg TNT/g wet wt tissue in N. arenaceodentata and at 6.3 μg TNT/g wet wt tissue in L. plumulosus. The growth end point demonstrated an apparent hormesis effect in both N. arenaceodentata and L. plumulosus with enhancement (significant for N. arenaceodentata) occurring at the lower TNT concentrations. Growth was significantly reduced at the highest TNT exposure of 10.0 μg TNT/g wet wt tissue in L. plumulosus. Reproduction was significantly reduced at a tissue concentration of 6.3 μg TNT/g wet wt tissue in L. plumulosus. The results of this study demonstrate that both N. arenaceodentata and L. plumulosus are sensitive to the presence of sediment‐associated TNT and that more information is needed about the toxicity of TNT to benthic fauna to facilitate risk assessment and management of TNT‐contaminated sites.
