The Deep Water Horizon oil platform fire in the Gulf of Mexico resulted in a massive oil spill in the spawning waters of blue fin tuna. Scientists studying the effects on the tuna have recently announced a major discovery (AAAS meeting, Science).
They have found that the exposure to aromatic hydrocarbons creates instability in heart muscle contractions. This leads to cardiac arrhythmia… ultimately heart failure.
The scientists consider this cardio-toxicity of oil extends well beyond tuna because the (potassium channel) physiology involved is shared widely across vertebrate species, including humans. Since heart failure is a major cause of death in humans, excessive exposure to aromatic hydrocarbons may be another nail to seal the coffin of fossil fuels, including CSG, and hydrocarbon contaminated water and air. Hooray!
Further research is required. Meanwhile you may wish to ponder the real reason why your favourite perfume makes your lover’s heart flutter.
