According to a recent report on CNN, the state of Louisiana has reported 162 cases of illness relating to the BP oil spill. Of these, 128 involved workers on oil rigs, or those working on clean-up. At this writing, at least 21 workers have been hospitalized because of their complaints. Symptoms reported include dizziness, nausea and breathing issues. It is well known that workers exposed to oil spill toxins are at risk for long-term health problems. According to the National Resources Defense Council, various components of crude oil, such as benzene, toluene and polynuclear aromatic hydrocarbons, present risks. All are known carcinogens. Other components of oil, like mercury and lead, are also toxic. According to a CNN report, workers involved in the 1989 Exxon Valdez oil spill cleanup are still reporting health problems. One examination of health records of 11,000 Exxon Valdez cleanup workers found that 6,722 of them had gotten sick. The government and the company called those illnesses the "Exxon crud", a flu or cold that Exxon was not required to report to federal health officials, CNN said. Unfortunately, neither Exxon nor the government has conducted any long-term studies on the health problems experienced by the workers. However, an environmental activist who did study the Exxon Valdez disaster told CNN that cleanup workers in the Gulf are showing "the exact identical symptoms down here that we had 21 years ago."
