Health Dangers Behind the Oil Spill

Guest Post  sent by Ken Martin.

The BP oil spill in the Gulf of Mexico, which began after an explosion crippled the Deepwater Horizon drilling rig, is now the biggest oil disaster in U.S. history. Cleaning the mess will take months, and the longer-term effects on health and wildlife will take years to heal.

Right Now

Sickness among clean-up workers: The combination of oil fumes and heat from the Gulf has led to several workers being hospitalized from fumes, and the curious chemical makeup of some of the substances used to clean up the oil can often lead to skin irritation or, at high levels, cancer.

Danger to marine life: The underwater nature of the spill means it’s that much closer to undersea life, and therefore able to do more damage in a shorter amount of time.

Aggravation of existing illnesses: People already suffering from asthma or similar lung diseases could see their conditions worsened because of exposure to oil and chemicals.

Pregnancy risks: The oil contains many volatile and toxic chemicals, some of which have been linked to premature birth, low birth weight, and miscarriages, making the Gulf Coast region a dangerous one for pregnant women.

Smoke fallout: Planned burns of spilled oil on the ocean’s surface have a way of backfiring. Often, particles held in the smoke drift down to earth and wind up in people’s eyes and lungs, which can aggravate existing medical conditions for some.

In the Future

Neurological disorders: Some of the fishermen who cleaned up the Exxon Valdez oil spill in 1989 wound up suffering neurological problems as a result of prolonged exposure to a toxic cocktail of chemicals.

Food contamination: There’s still no telling how badly the food chain will be damaged by the oil spill. One scientist at the National Resources Defense Council said there will be a “legacy of contamination.”

Oxygen depletion: Hypoxia occurs when dissolved oxygen in the water is reduced so much that the imbalance begins to harm aquatic lifeforms. The process is exacerbated by the microbes in the chemicals used to clean up the leaking oil.

Dispersion of oil: Many experts are predicting that the oil will continue to flow into the Gulf well into August, which increases the likelihood that it might be picked up by the Gulf Stream currents and carried out to the Atlantic Ocean. That would, in turn, affect animals dwelling there, including dolphins.

Lung disease: One of the dispersants being used to clean the spill, Corexit, is one of the most toxic available, which could lead to potential lung problems for cleaners and workers who inhale the fumes and particles without wearing proper breathing equipment.

Climate Change and Increased Hazard Risk

Climate change could cause increasing and unpredictable hazard risks in mountainous regions, according to a new study from the University of Exeter and Austrian researchers. The study analyzes the effects of two extreme weather events — the 2003 heatwave and the 2005 flood — on the Eastern European Alps. It demonstrates what impact events like these, predicted to become more frequent under a changing climate, could have on alpine regions and what implications these changes might have for local communities.

Some Basic Facts about Maps from an Old Book

While reading an old book by Captain R.P.Cave found some easy and useful facts about maps and thought of  sharing with you all.Here they are:

  • A map is a  representation on paper of a certain area of country.
  • Fundamentally, a map is nothing more than a picture from which one can visualise the subject which it portrays.
  • A map is a diagram showing the details and features which exists on the ground.
  • A map can never be completely up to date ,for there must must always be features which have appeared since the map was made.
  • A map cannot show everything because there is not room to do so.

There’s more water on the moon

Recent moon missions have shown frozen water in shadowed craters on the moon’s surface, and ice under the gray dust. It could have been carried there by bits of comets as asteroids hitting the surface, however. A new study published in the Proceedings of the National Academy of Science shows there is much more water on the moon than that — findings important for future moon missions.
