We conducted a probability survey of 154 Oregon, USA, stream and river sites to assess the spatial extent of mercury (Hg) contamination in fish tissue. Samples consisted of whole-fish analyses of both small (<120 mm) and large (>120 mm) fish at each site, when both were present. Overall, Hg levels (microgram/g) in small fish (mean = 0.031; standard deviation [SD] = 0.029), large piscivores (mean = 0.284; SD = 0.175), and large invertivores (mean = 0.055; SD = 0.047) were found within fairly… CONTINUE READING
