Canada has more than 13,000 beekeepers with almost 1,000,000 beehives spread across every province. Together, they produce about 40,000,000 kilograms of honey each year. That is enough for roughly one kilogram of honey for every Canadian.

When honeybees forage, they collect nectar, pollen and water from nearby flowers. These flowers contain traces of the chemicals in the soil and water where they grow.

As honeybees fly, they also pick up dust and other tiny particles from the air and any surfaces they touch. Some of these particles include metals from human activities like burning fossil fuels or industrial pollution.

By the time the bee has returned to its nest it is covered, inside and out, with the chemicals found in its local area. In this way, the honey in a beehive is a mix of everything the bees gather within about a three-kilometer area. Learning how to read the composition of honey will allow us to understand the chemical makeup of any given environment.

The honey produced by the tireless work of the honeybee is nothing short of an untapped goldmine of environmental data that could help us better understand the spread of environmental pollutants.

Our research — focusing on the Manchester area in the U.K. — proposes using honey as a window into the chemical make-up of a local area. Our team comprised of researchers from Dalhousie University in Canada and the University of Manchester in the United Kingdom. We measured metal........
