Multiphase redistribution differences of polycyclic aromatic hydrocarbons (PAHs) between two successive

Rufeng LI,Chenghong FENG,Dongxin WANG,Baohua LI,Zhenyao SHEN

Frontiers of Environmental Science & Engineering 2016, Volume 10, Issue 2,   Pages 381-389 doi: 10.1007/s11783-015-0817-7

Abstract: This study took polycyclic aromatic hydrocarbons (PAHs) as typical organic contaminants and investigatedResults showed that successive sediment suspensions lowered the concentration of dissolved PAHs in theoverlying water via facilitating the re-adsorption of dissolved PAHs onto the suspended particles.Fast-release and slow-release periods of PAHs were successively observed in the both suspensions.More vigorous desorption and re-absorption of PAHs were induced in the second suspension.

Application of probabilistic risk assessment at a coking plant site contaminated by Polycyclic AromaticHydrocarbons

XIA Tianxiang,JIANG Lin,JIA Xiaoyang,ZHONG Maosheng,LIANG Jing

Frontiers of Environmental Science & Engineering 2014, Volume 8, Issue 3,   Pages 441-450 doi: 10.1007/s11783-013-0572-6

Abstract: Application of Probabilistic Risk Assessment (PRA) and Deterministic Risk Assessment (DRA) at a coking plant site was compared. By DRA, Hazard Quotient (HQ) following exposure to Naphthalene (Nap) and Incremental Life Cancer Risk (ILCR) following exposure to Benzo(a)pyrene (Bap) were 1.87 and 2.12 × 10 . PRA revealed valuable information regarding the possible distribution of risk, and risk estimates of DRA located at the 99.59th and 99.76th percentiles in the risk outputs of PRA, which indicated that DRA overestimated the risk. Cleanup levels corresponding acceptable HQ level of 1 and ILCR level of 10 were also calculated for both DRA and PRA. Nap and Bap cleanup levels were 192.85 and 0.14 mg·kg by DRA, which would result in only 0.25% and 0.06% of the exposed population to have a risk higher than the acceptable risk, according to the outputs of PRA. The application of PRA on cleanup levels derivation would lift the cleanup levels 1.9 times for Nap and 2.4 times for Bap than which derived by DRA. For this coking plant site, the remediation scale and cost will be reduced in a large portion once the method of PRA is used. Sensitivity analysis was done by calculating the contribution to variance for each exposure parameter and it was found that contaminant concentration in the soil ( ), exposure duration ( ), total hours spent outdoor per day ( ), soil ingestion rate ( ), the air breathing rate ( ) and bodyweight ( ) were the most important parameters for risk and cleanup levels calculations.
