Prediction of lead concentration in soil using reflectance spectroscopy

Ali Al Maliki, David Bruce, Gary Owens

Environmental Technology & Innovation > 2014 > 1-2 > Complete > 8-15

Visible–Near and short-wave infrared reflectance spectroscopy has the potential to become an important additional technique in the geosciences for soil classification, mapping and remote determination of soil properties and mineral composition. It is also becoming increasingly important to improve the spatial resolution of soil maps to better tackle localized issues such as soil contamination. Long-term...

Dye removal using iron–polyphenol complex nanoparticles synthesized by plant leaves

Zhiqiang Wang, Chunhe Yu, Cheng Fang, Megharaj Mallavarapu

Environmental Technology & Innovation > 2014 > 1-2 > Complete > 29-34

This paper examined the ability of iron–polyphenol complex nanoparticles (Fe–P NPs) synthesized by eucalyptus leaf extracts as a novel adsorptive flocculant to remove acid black 194 from aqueous solution. The influential parameters such as ratios of reagents, doses of Fe–P NPs, pH, temperatures and initial dye concentration were tested. The kinetics, experimental equilibrium and thermodynamic data...

Estrogen-responsive genes for environmental studies

Ryoiti Kiyama, Yun Zhu, Kayoko Kawaguchi, Nobuko Iitake, more

Environmental Technology & Innovation > 2014 > 1-2 > Complete > 16-28

Studying the effect of estrogenic chemicals, especially estrogenic endocrine disruptors, needs mechanism-based understanding of toxicity pathways, especially at the level of cell signaling. We first summarized how estrogen action can be monitored through gene expression profiles by means of estrogen-responsive genes, which are associated with or mediate various types of cell signaling through pathways,...

Reactivation of carbon exhausted sulfidogenic bioreactor by fractionated sweetmeat waste dosing: The role of neutralizing substance and nitrogen supplement

Bidus Kanti Das, Anna H. Kaksonen, Jayanta Bhattacharya

Environmental Technology & Innovation > 2014 > 1-2 > Complete > 35-45

The performance of passive sulfidogenic systems for the treatment of sulfate rich wastewater decreases over time due to the exhaustion of organic carbon. Bioreactors filled with spent mushroom compost (SMC) exhibited 90% sulfate removal for approximately 11 weeks in continuous operation. Performance efficiency declined sharply when dissolved organic carbon (DOC) concentration in the reactors reached...

Study of urban puddle sediments for understanding heavy metal pollution in an urban environment

Andrian A. Seleznev, Ilia V. Yarmoshenko

Environmental Technology & Innovation > 2014 > 1-2 > Complete > 1-7

Natural processes cause sedimentation in local surface depressed zones of the urban landscape with the formation of micro water bodies (puddles). The urban puddle sediments can be defined as a separate peculiar subtype of geochemical traps of the recent technogenic and anthropogenic sediments. Accumulation of pollutants over space and time is a remarkable advantage of urban sediments in comparison...

Are the resource strategies for sustainable development sustainable? Downside of a zero waste society with circular resource flows

Jihyun Lee, Anders Branth Pedersen, Marianne Thomsen

Environmental Technology & Innovation > 2014 > 1-2 > Complete > 46-54

The present study is a follow up study of Lee et al. (2014), which presented the mass flow of plastic and paper products in Europe with accompanying flows of three phthalates, i.e. DEHP, DBP, and BBP, in above mentioned products. This study aims to investigate how the resource strategies aiming at a sustainable and circular economy influence on the recirculation of micro-pollutants in the product...
