Tracing Pharmaceuticals in Water Systems: Focus on Neurodegenerative and Psychiatric Treatments.

Pharmaceutical residues in aquatic ecosystems pose significant environmental and public health challenges. Identifying the presence and levels of these pharmaceuticals is crucial. This study developed an analytical method to detect pharmaceuticals used for Alzheimer's (AD) and Parkinson's (PD) disease, including psychiatric drugs and the stimulant caffeine, targeting 30 compounds.

Comparative life cycle assessment of non-thermal plasma for the removal of pharmaceuticals from wastewater.

Wastewater effluents are a continuous source of pharmaceuticals in water bodies, which pose a serious environmental threat to aquatic ecosystems. This work provides a comprehensive technical, environmental and cost assessments of different advanced quaternary treatments for wastewater effluents, with special focus on novel Non-Thermal Plasma technology. For this porpouse Non-Thermal Plasma, Sand Filtration + Ozonation, Ultrafiltration, Ultrafiltration + Nanofiltration and Ultrafiltration + Reverse Osmosis technologies were compared with UV disinfection-based technology.

Temporal Analysis of Pharmaceuticals as Emerging Contaminants in Surface Water and Wastewater Samples: A Case Study.

Pharmaceuticals in the environment are a global concern, with studies in all continents highlighting their widespread occurrence and potential ecological impacts, revealing their presence, fate, and associated risks in aquatic ecosystems. Despite typically occurring at low concentrations (ranging from ng/L to µg/L), advancements in analytical methods and more sensitive equipment have enabled the detection of a higher number of pharmaceuticals. In this study, surface and wastewater samples were extracted using solid phase extraction and analyzed using ultra-high-performance liquid chromatography with tandem mass spectrometry.

Evaluating the impact of polycyclic aromatic hydrocarbon bioaccumulation in adipose tissue of obese women.

Polycyclic aromatic hydrocarbons (PAHs) are widespread across the environment and humans are unavoidably and constantly exposed to them. As lipophilic contaminants, these substances tend to accumulate in fatty tissues as adipose tissue and exposure to these endocrine disruptors has been associated with severe health hazards including prevalence and incidence of obesity. Previous studies have shown significantly higher concentrations of PAHs in adipose tissue compared to other human samples, such as urine and plasma, which are typically used for PAHs assessment.

Analysis of atorvastatin in environmental waters: Validation of an electrochemical molecularly imprinted polymer sensor with application of life cycle assessment.

The widespread presence of pharmaceuticals in wastewater effluents after treatment stands as a significant challenge faced in the field of wastewater management and public health. Governments and the scientific community have worked to meet this urgent need for effective solutions. Nevertheless, the development of detection strategies for pharmaceutical monitorization capable of delivering rapid, on-site, and sensitive responses remains an ongoing necessity.
