ABSTRACT Concentrations of total organic carbon (TOC), petroleum hydrocarbons, polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) were determined in 84 near-surface soils (5–20cm depth) taken from a 255km 2 area Glasgow the Clyde Basin, UK, during July 2011. Total hydrocarbon range was 79–2,505mgkg –1 (mean 388mgkg ; median 272mgkg ) which fraction 13–74 % 44 %, 43 %) saturates 28–87 56 57 %). ∑ 16 PAH varied 2–653mgkg 32.4mgkg 12.5mgkg 31 2.47–852mgkg 45.4mgkg 19.0mgkg ). ∑PCB tri-hepta 2.2–1052μgkg 32.4μgkg 12.7μgkg 7 0.3–344μgkg 9.8μgkg 2.7μgkg The concentration, distribution source persistent pollutants compared with those found urban other cities to human health assessment criteria for chronic exposure chemicals soil. concentrations encountered generally similar areas that had industrial history.
