Evaluation of the Removal of Selected Phthalic Acid Esters (PAEs) in Municipal Wastewater Treatment Plants Supported by Constructed Wetlands.

Phthalic acid esters (PAEs) have a negative impact on living organisms in the environment, therefore, are among the group of Endocrine Disrupting Compounds (ECDs). Unfortunately, conventional methods used in municipal wastewater treatment plants (MWWTPs) are not designed to eliminate PAEs. For this reason, the development of cheap and simple but very effective techniques for the removal of such residues from wastewater is crucial.

Metabolism of non-steroidal anti-inflammatory drugs by non-target wild-living organisms.

The presence of the non-steroidal anti-inflammatory drugs (NSAIDs) in the environment is a fact, and aquatic and soil organisms are chronically exposed to trace levels of these emerging pollutants. This review presents the current state of knowledge on the metabolic pathways of NSAIDs in organisms at various levels of biological organisation. More than 150 publications dealing with target or non-target analysis of selected NSAIDs (mainly diclofenac, ibuprofen, and naproxen) were collected.

Anti-inflammatory drugs in the Vistula River following the failure of the Warsaw sewage collection system in 2019.

At the end of August 2019, in Warsaw, the sewage collection system of the Wastewater Treatment Plant malfunctioned. During the subsequent 12 days, over 3.6 million m of untreated sewage was introduced from the damaged collector directly into the Vistula River.

Identification of Selected Antibiotic Resistance Genes in Two Different Wastewater Treatment Plant Systems in Poland: A Preliminary Study.

Antibiotic resistance is a growing problem worldwide. The emergence and rapid spread of antibiotic resistance determinants have led to an increasing concern about the potential environmental and public health endangering. Wastewater treatment plants (WWTPs) play an important role in this phenomenon since antibacterial drugs introduced into wastewater can exert a selection pressure on antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARGs).

Evaluation of the Possibility of Using Hydroponic Cultivations for the Removal of Pharmaceuticals and Endocrine Disrupting Compounds in Municipal Sewage Treatment Plants.

The problem of the presence of pharmaceuticals and endocrine disrupting compounds (EDCs) in the environment is closely related to municipal wastewater and in consequence to municipal wastewater treatment plants (MWWTPs) because wastewater is the main way in which these compounds are transferred to the ecosystem. For this reason, the development of cheap, simple but very effective techniques for the removal of such residues from wastewater is very important. In this study, the analysis of the potential of using three new plants: (Papyrus), (Yellow pimpernel), and (European spindle) by hydroponic cultivation for the removal of 15 selected pharmaceuticals and endocrine disrupting compounds (EDCs) in an MWWTP is presented.

Simultaneous determination of non-steroidal anti-inflammatory drugs and natural estrogens in the mussels Mytilus edulis trossulus.

In this study, an ASE (Accelerated Solvent extraction)-SPE (Solid Phase Extraction)-GC/MS(SIM) method for the simultaneous determination of five non-steroidal anti-inflammatory drugs (NSAIDs: ibuprofen (IBU), paracetamol (PAR), diclofenac (DIC), naproxen (NAP) and ketoprofen (KET)) and three natural estrogens (estrone (E1), 17β-estradiol (E2), estriol (E3)) in mussels was proposed, which is simple, cheap and easy for use in environmental laboratories. For the first time, the sorbents: PSA (Primary Secondary Amine) and FLORISIL®, placed directly inside the extraction cells, were used for the improvement of the ASE procedure for the isolation of these pollutants from mussel samples. The application of FLORISIL® especially allowed the purification of the extract to increase recovery, without the loss of analytes, or prolongation of the extraction time.
