For years, residents in some of Canada’s largest industrial cities have wondered whether toxins from petrochemical plants and other manufacturers are making them sick.

A new peer-reviewed study has found “strikingly high” rates of acute myeloid leukemia (AML) in Canadian border towns, including Sarnia, Ont., a city whose manufacturing sector is referred to as Canada’s Chemical Valley.

The study reviewed 18,085 Canadian cases of AML between 1992 and 2010. It found hot spots for this type of leukemia in several Canadian cities, including Hamilton, Thunder Bay, Sault Ste. Marie, Sarnia and St. Catharines.

Sarnia was at the top of the list.
