“…The sample was then sonicated for 30 minutes and placed on a hot plate (130℃) until it was almost dry. Next, HNO 3 and HF were put into the tank at a ratio of 1:1 and covered with the lid. Finally, the tank was placed into an air oven overnight at a temperature of 170℃.…”

“…Researchers have found that great quantities of contaminated sediment exist in organic compounds (Charrasse et al, 2014). The water quality in most cities has deteriorated, and the rivers into which much of the wastewater is deposited has become malodorous, This is due to the high level of alluvial-contaminated sediment which remains in the water long after the pollutants have been introduced (Wang et al, 2015).…”

Jia et al.: Efficiency of phytoremediation on the sediments co-contaminated by heavy metals and organic compounds and the role of microbes in the remediation system -141 - Abstract. This paper presents the findings of a one-year research project, in which participants explored the function of microbe remediation efficiency and plant growth. Corn and rye grass were planted separately and in mixed quantities to remediate sediments co-contaminated by heavy metals and typical polycyclic aromatic hydrocarbons (PAHs). The study revealed that both the number and the activity of microbes were affected during the sediment remediation process. It also showed that the overall trend at first increased and then decreased, with the microbial numbers reaching their highest levels during the second week of soil cultivation. In the heavy-metal, organic-compound, co-contaminated matrix, the researchers found that mono-cropping the corn removed more lead, with the removal rate reaching a high of 12.96%. They found further that in the mixed-planting pattern, the removal rate of zinc reached a maximum level of 31.4%. The results of the study showed conclusive evidence that organic matters play an important role in the plant-microbe remediation of contaminated sediments.

“…The apparent distribution coefficients (K d ) defined as the total sediment concentration (C s ) to the water concentration (C w ) ratios are calculated from the analysis performed by accelerated solvent extraction (according to Belles et al (2016a)) for C s and from the experiment of PS equilibration for C w (Lohmann et al, 2005;Charrasse et al, 2014). If K d provides quick and easy information for predicting the distribution of pollutants between the water and the solid phase, it suffers from lack of precision because it does not take into account the PAH not freely exchanged between the dissolved and sorbed states.…”

Passive sampling with low-density polyethylene (LDPE) was assessed to study the way it accumulates contaminants in sediment. Strips of LDPE were deployed in river sediment for a period of two months to evaluate their polycyclic aromatic hydrocarbon (PAH) accumulation following two modes: LDPE buried in sediment and exposed to pore water flow and contaminants desorbed from particles were compared to LDPE strips in the same sediment but in a confined space. The results present an obvious difference of accumulation between the two modes of exposure. LDPE exposed to pore water accumulated PAH depending on their hydrophobicity whereas LDPE only exposed to contaminant desorption from confined particles did not accumulate nor desorb PAH significantly. This observation shows that LDPE only takes up PAH present in pore water and not the PAH bound to sediment particles. Accumulation in LDPE is not the result of forced desorption from particles. The present study also found that LDPE sampling cannot estimate adsorbed molecules in confined sediment nor in turbid water. LDPE is an efficient tool for investigating pore water, the fate of micropollutants in sediment, the effect of bioturbation and bioirrigation on micropollutants and the effect of micropollutants on bioturbation activity.Palabras clave: PBD, HAP, contaminante disuelto, adsorción, representatividad, área urbana RESUMEN Se llevó a cabo un muestreo pasivo con polietileno de baja densidad (PBD) para analizar la manera en que puede acumular contaminantes en el sedimento. Se emplearon tiras de PBD en sedimento de río por un periodo de dos meses para evaluar la acumulación de hidrocarburos aromáticos policíclicos (HAP) a través de dos modalidades: PBD enterrado en el sedimento y expuesto al flujo de agua intersticial y PBD expuesto a contaminantes desadsorbidos de partículas en el mismo sedimento pero en espacios confinados. Los resultados muestran una diferencia en la acumulación entre Rev. Int. Contam. Ambie. 33 (Especial Biotecnología e ingeniería ambiental) 23-32, 2017 DOI: 10.20937/RICA.2017 D.A. Devault and C. Gourlay-Francé 24 ambas modalidades de exposición. El PBD expuesto al agua intersticial acumuló HAP dependiendo de su hidrofobicidad, mientras que el PBD expuesto solamente a la desadsorción de partículas confinadas no acumuló o desadsorbió HAP de manera significativa. Esto muestra que el PBD sólo toma HAP presentes en el agua intersticial y no aquellos unidos a partículas en el sedimento. La acumulación de HAP en el PBD confinado, no es el resultado de la desadsorción forzada de las partículas. El presente estudio encontró que el muestreo con PBD no puede estimar las moléculas adsorbidas en sedimento confinado o en agua turbia. El PBD es una herramienta eficiente para investigar el agua intersticial, el destino de microcontaminantes en sedimentos, el efecto de la bioturbidez y la bioirrigación en microcontaminantes, así como el efecto de éstos en la actividad de bioturbación.
