Characterisation of Rare Earth Elements in Waste Printed Circuit Boards (WPCBs) and their bioleaching potential

(Corresponding) Gonzalez Baez A., Purchase D., Garelick H., Pantoja Munoz L.
Topic: 
Solid waste management
Printed circuit boards (PCBs) are part of everyday items such as cellular phones and computers, and they constitute a significant proportion of e-waste. PCBs contain hazardous components but also valuable and critical materials such as copper, gold, silver and rare earth elements. Rare earth...Read more

Recovery of sulphuric acid and valuable metals (Zn, Cu and REE) from acidic mine waters using nanofiltration

(Corresponding) López J., Reig M., Vecino X., Valderrama C., Gibert O., Cortina J.
Topic: 
Water and wastewater reuse
Acidic mine waters (AMWs) contains moderate concentrations of sulphuric acid, relatively high concentrations of metals (Al, Fe, Cu and Zn) and minor amounts or rare earth elements (REE). The established management routes for AMW treatment include a neutralization-precipitation step, which implies a...Read more

Recovery of rare earth elements from luminophores using the red alga Galdieria

Čížková M., Bišová K., Zachleder V., Mezricky D., Rucki M., (Corresponding) Vítová M.
Topic: 
Electric and electronic waste
The red alga Galdieria phlegrea was used as an experimental organism to test bioaccumulation of rare earth elements (REEs) from luminophores. Algal cells were cultured mixotrophically in a liquid medium with addition of glycerol as a source of carbon. Luminophores from two different sources (...Read more

Technology Critical Elements in industrial wastes as the source of soil contamination

Rachwal M., Jablonska-Czapla M., Grygoyć K., (Corresponding) Fornalczyk A., Willner J.
Topic: 
Soil and groundwater contamination and remediation
The intensive development of industry, especially the mining and metallurgy, automotive and electrical industries, as well as the growing demand, rapid consumption and "ageing" of most products, including electrical/electronic equipment, requiring regular replacement, affects the amount...Read more

Comparative effects of salinomycin and meso-2,3-dimercaptosuccinic acid (DMSA) on lead induced impairment of reproductive function in male mice

(Corresponding) Pavlova E., Kamenova K., Gluhcheva Y., Petrova E., Ivanova J., Atanassova N.
Topic: 
Heavy metals in the environment
Lead (Pb) directly targets testicular spermatogenesis and also the sperms in the epididymis inducing reproductive toxicity. In our study we compare the effects of meso-2,3-dimercaptosuccinic acid (DMSA) and tetraethylammonium salt of salinomycinic acid on Pb content and the endogenous levels of...Read more

Sources and transfer of Cu, Hg and Pb into marine food webs using innovative tracers (metal stable isotopes, trophic markers): results of a pilot study in a French coastal area

(Corresponding) Chouvelon T., Araujo D., Bouchoucha M., Briant N., Bruzac S., Crochet S., Knoery J., Ponzevera E., Rozuel E., Sireau T., Thomas B., Amouroux D., Bérail S., Brach-Papa C.
Topic: 
Heavy metals in the environment
Copper (Cu), mercury (Hg) and lead (Pb) are elements and contaminants of historical and emerging concerns in coastal environments. Although Cu is considered essential for living organisms, it is bioactive in a narrow range of optimal concentrations. Hg and Pb have no known biological role and are...Read more

Red Mud as a Secondary Source of Scarce Metals - Recovery using Red Microalgae

Náhlík V., Čížková M., Singh A., Bišová K., Mezricky D., Rucki M., (Corresponding) Vítová M.
Topic: 
Environmental biotechnology and bioenergy
Red mud is a by-product of the production of alumina from bauxite ore. Less than 2% of the red mud produced is currently being reused. The red mud contains a number of residual elements, some at a considerable concentration. The red microalga Galdieria sulphuraria was used to test the accumulation...Read more

Coupling Pb and Zn bioaccessibility with sequential and HNO3 extraction in soil from the industrial area of Volos, Greece

(Corresponding) Kelepertzis E., Botsou F., Sungur A., Sigala E., Daferera O., Kypritidou Z., CHRASTNÝ V., Argyraki A., Komarek M., Skordas K.
Topic: 
Heavy metals in the environment
The urban environment is a complicated system where various anthropogenic sources contribute to the accumulation of metals in soil, leading to potential negative environmental effects. Within this context, we performed single and sequential extractions in contaminated soil from the industrial area...Read more

Waste Printed Circuit Boards (WPCBs) as a potential source for the recovery of rare earth elements through bioleaching.

(Corresponding) Gonzalez Baez A., Pantoja Muñoz L., Garelick H., Purchase D.
Topic: 
Electric and electronic waste
Rare earth elements (e.g., neodymium, dysprosium and praseodymium) have contributed to the miniaturization, energy efficiency, durability, and high speed of many technology gadgets. Due to their electric conductivity, magnetic, luminescence and optical properties, rare earth elements (REE) are...Read more

Cultivation of milk thistle in Pb-contaminated urban soils

(Corresponding) Papadimou S., BARBAYIANNIS N., GOLIA Ε.
Topic: 
Soil and groundwater contamination and remediation
In order to remediate heavy metal-contaminated soils of urban areas, we conducted an experiment using a pharmaceutical phytic species such as milk thistle (Silybum marianum (L.) Gearn.). The experiment was carried out using two different soil samples (one acid and one alkaline) from urban areas...Read more
