英文摘要:
A study on vertical distribution of magnetic susceptibility, carcinogenic and endocrine disrupting PAHs was performed in the reclaimed mudflat sediments adjacent to the Thane Creek of Mumbai. The 5-rings PAHs and ΣC-PAHs were more dominant at 120�cm depth contributing 52.23% and 60.19% respectively to ∑�PAHs. The average ratio values of LMW/HMW PAHs (0.58); Fla/(Fla�+�Pyr) (0.50); Ant/(Ant�+�Phe) (0.50); BaA/(Chry�+�BaA) (0.48); BaP/BghiP (2.06), Phe/Ant (1.03) and BaA/Chr (0.93) indicate that the PAH contamination might have raised due to inefficient combustion and pyrogenic emissions during the open burning of solid waste in the vicinity. This was further supported by the anthropogenic ferri(o)magnetic loading over the last 100�years influencing the Creek sediments. The PAHs toxicity estimation was performed by calculating the toxic equivalent quantity (TEQ) value of 8.62�ng TEQ/g which was below the safe level (600�ng TEQ/g) suggested by the Canadian risk-based soil criterion for protection of human health. � 2017 Elsevier Ltd
