Environmental genotoxicity and risk assessment in herring (Clupea harengus), Atlantic cod (Gadus morhua) and flounder (Platichthys flesus) caught in the Gotland Basins from the Baltic Sea (2010-2017)
(Corresponding) Pažusienė J., Valskienė R., Stankevičiūtė M., Butrimavičienė L., Baršienė J.
Topic:
Biomonitoring
The Gotland Basins are mostly polluted by anthracene, benz(a)anthracene, benzo(k)fluoranthene, cesium-137, DDE, dioxins, mercury and TBT. These chemicals have toxic, carcinogenic and immunotoxic effect to marine animals. After the World War II chemical weapons (CW) were transported from Germany and...Read more

Optimization of fabric phase sorptive extraction for the determination of selected pharmaceuticals in environmental waters
JIMENEZ-HOLGADO C., VOURDAS N., STATHOPOULOS V., (Corresponding) SAKKAS V.
Topic:
Emerging pollutants
There is a growing public and scientific concern about the possibility of ecosystem and human health effects from pharmaceuticals in environment. Results have shown that several types of environmental waters (drinking water, groundwater, surface water, treated water) were contaminated by the...Read more

Magnetic solid-phase extraction of pesticides in environmental water samples Fe3O4@SiO2@C18 nanoparticles coupled to GC-MS determination
KAPSI M., SAKKAS V., (Corresponding) ALBANIS T.
Topic:
Emerging pollutants
A rapid magnetic solid-phase extraction (MSPE) method coupled to Gas Chromatography-Mass Spectrometry (GC-MS) was developed for the simultaneous extraction of ten pesticides belonging to various categories (insecticides, herbicides and fungicides) in environmental water samples. The magnetic Fe3O4@...Read more

Removal of heavy metals from sewage sludge using combined hydrothermal pretreatment and chelate extraction
(Corresponding) Usťak S., Muňoz J.
Topic:
Wastewater treatment
The removal of heavy metals from sewage sludge using the combined influence of hydrothermal pretreatment and chelate extraction was tested. The classical method of batch extraction with chelates and the advanced hydrothermal pretreatment (HTP) extraction process with chelates were compared. Both...Read more

A method for the extraction of microplastics from solid samples using olive oil
(Corresponding) Scopetani C., Pellinen J., Pflugmacher S.
Topic:
Microplastics in the marine environment
Microplastics (MPs) extraction from sediment, sand and soil samples is a challenge that the scientific community is facing nowadays; currently there are no standardized and validated protocols and the most common methods rely on density separation techniques, often unable to separate high density...Read more
Impact on the effect of acetic acid in its aqueous forms on environments and its separations by solvent extraction method- A review
(Corresponding) Sofiya K., Karunanithi B.
Topic:
Emerging pollutants
Acetic acid is one of the top twenty commodities used in various industrial processes. Removal of acetic acid in its aqueous forms is a significant problem, and it cannot be discarded directly to the environment because of its acidity nature. The separation of acetic acid from its aqueous phase is...Read more

Development of efficient techniques for the removal of brominated flame retardants from polymer blends with composition that simulates WEEE
(Corresponding) Charitopoulou M., Papadopoulou L., Achilias D.
Topic:
Electric and electronic waste
Waste electric and electronic equipment (WEEE) has increased enormously because of the rapid expansion and consumption of electronic devices and their short lifespan. Recycling of WEEE is challenging, due to the presence of various materials including glass, metals and plastics (Buekens and Yang...Read more
Extent and distribution of microplastic contamination in the benthic sediment of Turag river in Bangladesh
Tofa T., (Corresponding) Chowdhury V., Nur S., Chowdhury M.
Topic:
Microplastics in water treatment: fate, toxicity assessment and removal technologies
Microplastics are ubiquitous in the aquatic environment. However, a limited number of studies have been conducted on the quantification of accumulated microplastics in benthic sediments of freshwater bodies, which pose threat to the health of benthic communities through food chain contamination...Read more

EXTRACTION AND DETERMINATION OF PHARMACEUTICAL COMPOUNDS ADSORBED INTO MICROPLASTICS
Santana-Viera S., Montesdecoa-Esponda S., Torres-Padrón M., (Corresponding) Sosa-Ferrera Z., Santana-Rodríguez J.
Topic:
Emerging pollutants
Microplastics (MPs) are pollutants of emerging concern. These small particles are found throughout the world. Its best-known negative effects are that they can confuse marine organisms that would feed on them, or block their airways. In addition, they have been shown to act as vectors of...Read more
AliCy as Extractant to Remove Iron from Copper-Free Extreme AMD for Further Extraction of Zinc
Nobahar A., Melka A., Neves L., Carlier J., (Corresponding) Costa M.
Topic:
Wastewater treatment
A previous work showed that copper can be specifically extracted from acid mine drainage (AMD) classified as high-acid and extreme-metals (pH 1.19, ~63 g/L Fe, ~6.5 g/L Al, ~5.3 g/L Cu, ~1.9 g/L Zn and ~0.1 g/L Mn), using 30% (v/v) Acorga M5640 in Shell GTL (a kerosene like solvent) as extractant...Read more
