<P> A study that investigated the health effects among children in Louisiana and Florida living less than 10 miles from the coast found that more than a third of the parents reported physical or mental health symptoms among their children . The parents reported "unexplained symptoms among their children, including bleeding ears, nose bleeds, and the early start of menstruation among girls," according to David Abramson, director of Columbia University's National Center for Disaster Preparedness . </P> <P> A cohort study of almost 2200 Louisiana women found "high physical / environmental exposure was significantly associated with all 13 of the physical health symptoms surveyed, with the strongest associations for burning in nose, throat or lungs; sore throat; dizziness and wheezing . Women who suffered a high degree of economic disruption as a result of spill were significantly more likely to report wheezing; headaches; watery, burning, itchy eyes and stuffy, itchy, runny nose . </P> <P> The spill had a strong economic impact to BP and also the Gulf Coast's economy sectors such as offshore drilling, fishing and tourism . Estimates of lost tourism dollars were projected to cost the Gulf coastal economy up to 22.7 billion through 2013 . In addition, Louisiana reported that lost visitor spending through the end of 2010 totaled $32 million, and losses through 2013 were expected to total $153 million in this state alone . The Gulf of Mexico commercial fishing industry was estimated to have lost $247 million as a result of postspill fisheries closures . One study projects that the overall impact of lost or degraded commercial, recreational, and mariculture fisheries in the Gulf could be $8.7 billion by 2020, with a potential loss of 22,000 jobs over the same time frame . BP's expenditures on the spill included the cost of the spill response, containment, relief well drilling, grants to the Gulf states, claims paid, and federal costs, including fines and penalties . As of March 2012, BP estimated the company's total spill - related expenses do not exceed $37.2 billion . However, by some estimations penalties that BP may be required to pay have reached as high as $90 billion . In addition, in November 2012 the EPA announced that BP will be temporarily banned from seeking new contracts with the US government . Due to the loss of the market value, BP had dropped from the second to the fourth largest of the four major oil companies by 2013 . During the crisis, BP gas stations in the United States reported a sales drop of between 10 and 40% due to backlash against the company . </P> <P> Local officials in Louisiana expressed concern that the offshore drilling moratorium imposed in response to the spill would further harm the economies of coastal communities as the oil industry directly or indirectly employs about 318,000 Louisiana residents (17% of all jobs in the state). NOAA had closed 86,985 square miles (225,290 km), or approximately 36% of Federal waters in the Gulf of Mexico, for commercial fishing causing $2.5 billion cost for the fishing industry . The U.S. Travel Association estimated that the economic impact of the oil spill on tourism across the Gulf Coast over a three - year period could exceed approximately $23 billion, in a region that supports over 400,000 travel industry jobs generating $34 billion in revenue annually . </P>
