Female professor: The Chesapeake Bay, on the east coast of the United States, is huge--the largest estuary in the U.S., and it's very important to local economies. But, like many of the world's waterways, the Chesapeake is being polluted. And efforts to stop that from happening have...

23. A process for modifying and controlling infectious agent levels in a body of water chosen from the group consisting of a lake, pond, stream, river, estuary or ocean bay including the steps of: a) identifying an area of water within said body of water flowing at a speed in the range...
Data also showed that in the estuary, water temperatures can reach extreme values (35.2 °C) during the hottest season, which can be stressful, especially for less mobile or sessile species. These kinds of extreme temperature values have also been reported for other estuar- ies (see Hofmann, ...
Our examination of other west coast estuaries of USA and Canada revealed that mean 4-NP concentrations in gobies and mussels from Morro Bay were significantly higher than those from a more urbanized estuary, San Francisco Bay (goby: 11100 ± 3800 ng g−1 lw) and from a remote...
The toxicity observed in bivalve shellfish is not the result of a simple lineal process but of a complex balance from a chain of processes (uptake, biotransformation, elimination, allometric variability) that are species-specific (Section 6). This work reviews: (i) the toxins unambiguously found...
The tested insecticide significantly inhibited the growth of roots in wheat, a result that was also confirmed by a microbiotest application (62% root growth inhibition in sorghum and 100% germination inhibition in white mustard and garden cress). In ferns, even for the lowest concentration, the ...
