TL;DR: Results showed that most heavy metals in ditch and riparian wetlands did not significantly differ from those in reclaiming wetlands in A region, while significantly lower for Cd, Cu, Pb, and Zn in reclaimed wetlands in B region, suggesting higher effects of long-term reclamation.
381 citations
TL;DR: Experimental results have shown that lower pH and higher concentration of dissolved oxygen favor the phenol degradation and that the presence of Fe2+ enhanced TOC removal of phenol solutions.
269 citations
TL;DR: The redundancy analysis (RDA) revealed that both urbanization and reclamation processes would cause similar metallic characteristics, and sediment organic matter (SOC) might be the prominent influencing factor.
250 citations
TL;DR: In this paper, the concentrations of heavy metals in agricultural soils (As, Cr, Cu, Mn and Ni) and in wheat plants at different stages of growth (Cd, Pb, and Zn) were investigated near the Fengfan lead-acid battery factory in Baoding, China.
196 citations
TL;DR: Results show that most of heavy metals detected in water and sediments are lower than that in Yangtze River Delta and Pearl River Delta, and the biomagnification of the selected nine heavy metals in the food webs is not significant.

TL;DR: In this paper, the authors present a general review of advanced oxidation processes developed to decolorize and/or degrade organic pollutants and highlight the application of nano-zero valent iron in treating refractory compounds.
Abstract: The increase in the disposal of refractory organics demands for newer technologies for the complete mineralization of these wastewaters. Advanced oxidation processes (AOPs) constitute a promising technology for the treatment of such wastewaters and this study presents a general review on such processes developed to decolorize and/or degrade organic pollutants. Fundamentals and main applications of typical methods such as Fenton, electro-Fenton, photo-Fenton, sono-Fenton, sono-photo-Fenton, sono-electro-Fenton and photo-electro-Fenton are discussed. This review also highlights the application of nano-zero valent iron in treating refractory compounds.

TL;DR: This paper provides a comprehensive ecological and health risk assessment on the heavy metals in soils in Chinese industrial and agricultural regions and thus provides insights for the policymakers regarding exposure reduction and management.
1,019 citations
TL;DR: This review focuses on and describes heavy metal contamination in soil-food crop subsystems with respect to human health risks, and explores the possible geographical pathways of heavy metals in such subsystems.
952 citations
TL;DR: In the first part of this two article series on the imperative technologies for wastewater treatment, a review of oxidation processes operating at ambient conditions was presented It has been observed that none of the methods can be used individually in wastewater treatment applications with good economics and high degree of energy efficiency Moreover, the knowledge required for the large-scale design and application is perhaps lacking as mentioned in this paper.

TL;DR: In this article, it was shown that acid red 14 (AR14) can be photocatalytically degraded using TiO 2 suspensions irradiated by a UV-C lamp (30 W).
Abstract: Acid Red 14 (AR14), commonly used as a textile dye, could be photocatalytically degraded using TiO 2 suspensions irradiated by a UV-C lamp (30 W). The experiments showed that TiO 2 and UV light had a negligible effect when they were used on their own. The semi-log plot of dye concentration versus time was linear, suggesting first order reaction ( K =1.41×10 −2 min −1 ). The effects of some parameters such as pH, the amount of TiO 2 and initial dye concentration were also examined. The photodegradation of AR14 was enhanced by the addition of proper amount of hydrogen peroxide, but it was inhibited by ethanol. From the inhibitive effect of ethanol it was deducted that hydroxyl radicals played a significant role in the photodegradation of dye, but a direct oxidation by positive holes was probably not negligible. Accordingly, it could be stated that the complete removal of color, after selecting optimal operational parameters could be achieved in a relatively short time, about 3.5 h.
