Abstract
Kurek et al. (1) provide a valuable contribution concerning oil sands development. The authors should also be congratulated for not drawing irresponsible inferences about human cancer risks from polycyclic aromatic hydrocarbons (PAHs) and for accurately reporting substantially lower PAH contamination of sediments for their study lakes vs. popular Alberta recreational lakes: Wabamun, Pigeon, and Lac St. Anne. Kurek et al.’s finding of detectably elevated PAHs in sediments of five pothole lakes (four with depths of 1.5–1.7 m; three with areas less than 5 ha; and dissolved organic carbon levels from 20.6 to 71.5 mg/L, mean 42.5 mg/L) (table S1 in ref. 1) close to oil sands development is not surprising. Lakes NE13 and NE20 are within ∼10 km (figure 1 in ref. 1).
