Abstract
Ultraviolet (UV)–dissolved organic carbon (DOC) models were developed using surface samples collected from 58 lakes located 8–128 km from the metal smelters in Sudbury, Canada. Highly significant (R2 = 0.93–0.95) relationships were found between absorbance coefficients (Kaλ) and DOC within the UV-A and UV-B range (310, 320, 365 nm). Changes in UV absorbance with
