Abstract Carbamazepine (CBZ) is a pharmaceutical compound used in medical practice. Due to the ecotoxicological risk of its presence aqueous environment, researchers have been investigating removal by adsorption technique. The aim this study review works done on CBZ from water adsorption. Carbon‐based materials were best types adsorbent for uptake (> 200 mg g −1 ). Molecularly imprinted polymer (MIP) and carbon nanotubes (CNTs) showed especially good capacities. key mechanisms π‐π interaction, electrostatic interactions, hydrogen‐bonding hydrophobic interactions.

Contamination of surface waters by pharmaceuticals is an emerging problem globally. This because the increased access and use a growing world population lead to environmental contamination, threatening non-target species in their natural environment. Of particular concern are neuroactive pharmaceuticals, which known bioaccumulate fish impact variety individual processes such as reproduction or behaviour, can have ecological impacts compromise populations. In this work, we investigate occurrence bioaccumulation 33 brain, muscle liver tissues multiple collected four different estuaries (Douro, Tejo, Sado Mira). total, 28 were detected water 13 tissues, with reaching maximum concentrations 1590 ng/L 207 ng/g ww, respectively. The highest levels frequency detection samples psychostimulants, antidepressants, opioids anxiolytics, whereas antiepileptics, anxiolytics antidepressants showed concentrations. Bioaccumulation was ubiquitous, occurring all seven estuarine marine species. Notably, compounds every brain samples, 95% tissues. Despite variations pharmaceutical among estuaries, patterns consistent systems, generally higher followed muscle. Moreover, no link between compounds' lipophilicity, habitat trophic observed.

Eighty-one were detected aqueous phase, whereas sixty-two sediment. Carbamazepine (CBZ) was most frequently identified PhAC water, found 91.5% all samples. However, highest concentrations measured for lamotrigine (344.8 μg·L-1) caffeine (221.4 μg·L-1). Lidocaine occurring (73.8%), maximum CBZ (395.9 ng·g-1) tiapride (187.7 ng·g-1).

The presence of emerging organic contaminants (EOCs) in the environment is increasing and requires development technologies for their effective removal. Therefore, a literature review on behavior EOCs during municipal wastewater treatment, both major treatment systems particularly constructed wetlands (CWs), was carried out. study also reviewed anaerobic digesters (ADs) advanced oxidation processes, TiO2-based photocatalysis, which are being proposed as promising pre- post-treatments combination with CW. following ten compounds were screened: acetaminophen (ACE), ofloxacin (OFL), caffeine (CAF), carbamazepine (CBZ), ketoprofen (KET), ibuprofen (IBU), diclofenac (DCL), clofibric acid (ACB), bisphenol A (BPA), sotalol (SOT). degradation pathways selected largely influenced by physicochemical biochemical properties. Sorption biodegradation main elimination mechanisms found AD CW systems, where aerobic environments improves efficiency EOCs. However, various appear recalcitrant.

The removal of emerging pollutants from municipal wastewater was studied for the first time using a three-step pilot-scale system: 1) hybrid digester (HD) as step, 2) subsurface vertical flow constructed wetland (VF) second and 3) photodegradation (PD) unit third step or post-treatment. HD VF units were built operated in series with effluent recirculation at pilot scale. For PD post-treatment, three alternatives lab-scale, i) UVC irradiation 254 nm (0.5 h exposure time), ii) UVA 365 TiO2-based photocatalyst iii) sunlight photocatalyst, last two 1 2 h.
