253 | Fishie Mercury and a Crazy Little Thing Called Peat

You may have heard that eating too much fish may put you at risk of mercury poisoning, but how does mercury get into fish in the first place? Hosts Gregory Robinson and Yimin Chen speak with biologist Jennifer Blythe about the ecology of organic mercury - from the peat-loving, Sulphate-reducing bacteria that produce it, down to the trout on your dinner table. Along the way, we'll also hear about bog bodies, black flies, and other exciting stories of field work in the marshlands of Ontario.
