Rikki Ott, marine toxicologist and Exxon Valdez survivor, talks to GreenopolisTV about the effects of air pollution due to oil spills. Rikki says based on air monitoring conducted by the Environmental Protection Agency (EPA) in a Louisiana coastal community, findings show that airborne levels of toxic chemicals like hydrogen sulfide, and volatile organic compounds, now far exceed safety standards for human exposure currently in those areas.
The first oil from the Gulf of Mexico spill has entered an ocean current that could take it to Florida and up the east coast of the US, scientists say. European scientists warn the spill could reach Florida within six days.
Oil has been spewing into the Gulf since the offshore drilling rig Deepwater Horizon, leased by oil giant BP, exploded off the coast of Louisiana on 20 April and sank two days later.
Satellite images released by the European Space Agency (ESA) depict a streak of oil stretching south from the main slick into the Loop Current - a body of fast-flowing water coming from the Caribbean which the agency says is likely to propel oil towards Florida within six days.Meanwhile, astronauts and cosmonauts aboard the International Space Station have said they could see the oil spill while passing over the Gulf of Mexico.
"It looks very scary," Russian cosmonaut Oleg Kotov told reporters via a video link.
