Study of North Atlantic Ocean reveals decline of leaded petrol emissions

A new study of lead pollution in the North Atlantic provides strong evidence that leaded petrol emissions have declined over the past few decades. For the first time in around 40 years, scientists have detected lead from natural sources in samples from this ocean. In the intervening period, the proportion of lead in the ocean from humanmade sources, most importantly leaded petrol emissions, had been so high that it was not possible to detect any lead from natural sources.
