samples of sediment or water, we are not going to learn very 
much. And by the same token, I feel that if biologists just 
perform classical bioassays and the like, while important, they 
are not going to get the total picture either. I believe we 
have to combine our efforts and start to utilize some of the 
technologies that researchers in medical schools have used for 
years, e.g., immunology, embryology, enzyme kinetics, and every¬ 
thing else to try to get a better understanding. 
In closing, I'd like to say that I think the resources in 
the Chesapeake Bay are in pretty good shape. It looks like, or 
the signs are, that some of the levels of some of the PAHs may 
be increasing in the Bay. We know they can be harmful. We have 
problem areas in the Elizabeth River and Baltimore Harbor; some 
of the other smaller tributaries are highly impacted with 
waste. In general, we're in pretty good shape. I hope that we 
have caught this problem of chemical pollutants in time. With 
that I would like to turn the program over to my colleague.
