Contaminants of Emerging Concern (CECs) with estrogenic or estrogenic-like activity have been increasingly detected in aquatic environments and have been an issue of global concern due to their potential negative effects on wildlife and human health. This study used the MCF-7 cell proliferation assay (E-Screen) to assess the estrogenic activity profiles in Maryland Coastal Bays (MCBs), a eutrophic system of estuaries impacted by human activities. Estrogenic activity was observed in all study sites tested. Water samples from MCBs increased MCF-7 cell proliferation above the negative control from 2.1-fold at site 8, located in Sinepuxent Bay close to the Ocean City Inlet, to 6.3-fold at site 6, located in Newport Bay. The proliferative effects of the sediment samples over the negative control ranged from 1.9-fold at the Assateague Island National Seashore site to 7.7-fold at the Public Landing site. Moreover, elevated cell proliferation (p < 0.05) was observed when cells were co-exposed with 17ß-Estradiol (E2), while reduction in cell proliferation was observed when cells were co-exposed with the antagonist ICI 182, 780 suggesting that cell proliferative effects were primarily mediated by the estrogen receptor (ER). These results suggest the occurrence of some estrogenic or hormonal-like compounds in the MCBs and are consistent with our previous findings based on vitellogenin analyses.

<em>Abstract</em>.—Hurricanes Katrina and Rita critically impacted the northern Gulf Coast. Shrimping and other commercial fishing industries saw large scale destruction of vessels and shore based facilities in addition to a deposition of large amounts of debris on fishing grounds from Alabama to Louisiana. In 2006, the National Oceanic and Atmospheric Administration’s (NOAA’s) Office of Coast Survey and Office of Response and Restoration started the implementation of a large scale hazards survey program to map the coastal waters of Louisiana, Mississippi, and Alabama. The first phase of the effort involved surveying more than 600 square nautical miles of coastal bays and nearshore waters with sidescan and single beam acoustic sonar. Survey findings are posted each week on a NOAA public Web site displaying the location of each hazard and debris found. The survey work is also updating the NOAA navigation charts for coastal areas that are used heavily by fishing vessels, the navigation industry, and recreational boaters. Survey planning and implementation is conducted cooperatively with the marine fisheries agencies of Alabama, Mississippi, and Louisiana.
