VANCOUVER — A brand new examine from the College of British Columbia says honey from city honey bees may also help pinpoint the sources of environmental pollution equivalent to lead.
Scientists from the college’s Pacific Centre for Isotopic and Geochemical Analysis analyzed honey from city beehives in six Metro Vancouver neighbourhoods the place they examined for lead, zinc, copper and different parts.
The researchers discovered the focus of parts elevated nearer to areas with heavy site visitors, greater city density and industrial exercise equivalent to transport ports.
Kate E. Smith, lead writer of the examine and a PhD scholar on the college, says the excellent news is that the chemical composition of honey in Vancouver displays its surroundings and is extraordinarily clear.
She says Metro Vancouver honey is effectively beneath the worldwide common for heavy metals equivalent to lead, and an grownup must eat greater than 600 grams, or two cups, of honey every single day to exceed tolerable ranges.
Smith says the focus of parts elevated nearer to downtown Vancouver, and is basically from artifical sources.
