Special Issue Information

Dear Colleagues,

The pollution of soil, sediment, and groundwater medium is rapidly increasing worldwide due to the use, transport, storage, and disposal of various chemicals. Meanwhile, the inefficient processing of sludge problems caused by ever-increasing sewage sludge production has become a bottleneck affecting the healthy development of wastewater treatment industry. The long-term exposure to these hazardous sustances is associated with serious chronic and acute human diseases leading to widespread concerns regarding the sustainability of ecological system. Thus, there is an urgent need to understand the biogeochemical processes of these pollutants in soil, sediment, wastewater and sludge, and then to propose effective practices to abate their contamination. Several currentremediation technologies can be classified into five different processes, i.e., physical, chemical, biological, thermal, and combined. However, effective and green remediation techniques are still in extremely high demand.

An exciting new Special Issue of Applied Sciences, entitled “Advances in Remediation Techniques for Polluted Solid–Liquid Mixtures (Soils, Sediments, Groundwater and Sludge)”, and published by MDPI, is open for submissions, and we would like to invite you to contribute to it. This Special Issue accepts research on new remediation and treatment methods applied to soils, sediments, groundwater and sludge, and how these impact the environment of soil and groundwater.

We look forward to receiving your contributions.

Plastic/rubber materials used as fasteners in equipment for analyzing or removing organic pollutants in water treatment technologies form an essential part of the device. Micropollutants in water are typically present at very low concentrations (ng/L to µg/L). Therefore, when designing, for example, units for advanced oxidation processes (AOPs) or planning sample handling, it is necessary to assess whether the material is compatible with the usually hydrophobic nature of the pollutants. As a model example, the possible interactions of estrogens, namely, estrone (E1), 17β-estradiol (E2), estriol (E3) and 17α-ethinylestradiol (EE2) with six commonly used plastic and rubber materials were investigated at environmentally relevant concentrations (100–500 ng/L). In the first phase, we proved that polyvinyl chloride (PVC), polytetrafluoroethylene (PTFE), polyvinylidene fluoride (PVDF) and ethylene propylene diene monomer (EPDM) materials adsorbed only negligible amounts of estrogens, while significant amounts of E1, E2 and EE2 were adsorbed onto Tygon S3™ material. Another unsuitable material was styrene butadiene rubber (SBR), sorbing a considerable quantity of estrone. A detailed test of EPDM at higher concentrations (300 and 500 ng/L) and prolonged soaking time showed significant sorption of EE2 after 12 h of soaking in both deionized and tap water matrices. Thus, EPDM, PTFE and PVDF are suitable materials for sample handling or producing devices for AOP treatment due to their chemical inertness and mechanical flexibility. The results suggest that plastic materials that come into contact with contaminated water must be carefully selected, especially when working at environmentally relevant concentrations. Full article
