Dynamics of Mirex and its principal photoproducts in a simulated marsh system
- 22 Downloads
Three simulated marsh systems were constructed, containing sediment, marsh plants, oysters, blue crabs, fiddler crabs, and two species of top minnows. Seawater entered each of the pools by flowing across a trough, two of which contained Mirex bait. Tidal fluctuations were simulated. Samples of water, bait, and animals were periodically analyzed. All animals concentrated Mirex. Three photoproducts accumulated on the bait particles, and both oysters and one species of fish accumulated one of the photoproducts.
