Research Interests

I am interested in the general area of aquatic ecotoxicology. Specific research areas include contaminated sediments, roadway runoff, pesticide toxicity, population-level effects and metal bioavailability. Pollutants in marine, estuarine and freshwater systems tend to accumulate in bottom sediments, so hazard assessment of sediment-associated contaminants has been a primary focus (Ross & Munawar, 1996; Munawar et al., 1996; Burton et al., 1996). Current sediment projects include research on the fundamental differences between sampling survey designs for status-and-trend analysis (two-dimensional grids) and studies driven by remediation initiatives (three-dimensional matrices). Methods development is also a concern, and recent thesis and dissertation topics have included the use of bioluminescent bacteria in micro-scale toxicity test systems (Ross, 1998; Ross et al., 1999; 2000), and the effect of sediment particle size distributions on toxicity test results (Ringwood et al., 1997). Another ongoing research goal is the improvement of predictive models for the bioavailability of cationic metal species and non-polar organic compounds in sediments.

A major research axis is the impact of non-point source (NPS) contamination on aquatic ecosystems. Mesocosm studies address the effects of sub-lethal does of pesticides on estuarine communities (DeLorenzo, Scott & Ross, 1999; DeLorenzo et al. 1999). A related project is investigating the effects of long-term, pulse-dosed exposure to cholinergic insecticides on the development and maintenance of bone in teleost fish (Karen et al., 1998; 2001a; 2001b).

A recent dissertation study related the toxic effects of suspected endocrine disrupting chemicals to genotype frequencies in the estuarine grass shrimp species Palaemonetes pugio. Another dissertation project is focussed on the effect of sediment metal exposure on metallothionein induction in sediment dwelling invertebrate Lumbriculus variegatus.

A recently launched project is investigating the effects of sediment particle size on heavy metal content, toxicity, bioavailability, and dietary uptake. In support of this goal, this laboratory is one of eight locations in the U. S. and Canada that comprise the Center for the Study of Metals in the Environment.
