Organic pollutants in the coastal environment off san diego, california. 1. Source identification and assessment by compositional indices of polycyclic aromatic hydrocarbons

摘要

Samples collected in January and June 1994 from the Point Loma Wastewater Treatment Plant (PLWTP) effluent, Tijuana river runoff, and microlayer, sediment trap, and surface sediment at several locations adjacent to the PLWTP outfall, mouth of the Tijuana River, and San Diego Bay were analyzed in an attempt to identify and assess the sources of hydrocarbon inputs into the Coastal marine environment off San Diego. Several compositional indices of polycyclic aromatic hydrocarbons (PAHs), for example, Alkyl homologue distributions, parent compound distributions, and other individual PAH ratios, were used to identify the sources Of PAHs.
