Anthropogenic silver in the Southern California Bight: a new tracer of sewage in coastal waters

摘要: Silver concentrations were measured in coastal surface waters from Santa Barbara, CA (United States) to San Quintin, Baja California (Mexico) the Southern Bight. distributions characterized by decreasing longshore and increasing offshore concentration gradients (3-39 pM) with highest levels near primary sources of anthropogenic inputs. The gradient demonstrated that silver is a particle reactive element short residence time (∼34 days) waters, where it rapidly scavenged same manner as lead
