Eating healthily but suffering from irregular heart beat (arrhythmia)? The answer could be the fish in your diet. They are getting contaminated from oil spills, and the oil has a pollutant that can affect heart health. The oil contains phenanthrene, a polycyclic aromatic hydrocarbon (PAH).
Most scientists had linked PAHs to cancer, but a team from Stanford University has discovered that they also damage the human heart. The PAH [highlight]causes irregular heartbeat and weaker contractions of heart cells[/highlight].
It’s been [highlight]discovered in bluefin and yellowfin tuna and mackerel[/highlight] they tested, which came from crude oil spills. Phenanthrene is also found in soil, storm water run-offs, derelict industrial sites and in the air.
It’s an unrecognised threat to global health, say the researchers, brought about by the widespread use of petroleum.
