Abstract:
... The concept of wastewater-based epidemiology also known as sewage epidemiology was proposed by Daughton in 2001. Wastewater-based epidemiology has become now a reality that makes it possible to determine consumption or exposure to chemical substances or pathogens in a population by measuring certain compounds (drugs of abuse, metabolites, or biomarkers) or microorganisms (viruses, bacteria, and pa ...
... Pyrolysis gas chromatography-mass spectrometry (Py-GC-MS) has great potential within environmental analysis. This technique is mainly used for the chemical identification of macromolecules that cannot be characterized by either liquid or gas chromatography due to their big size. Through pyrolysis (controlled thermal degradation), these macromolecules are broken down into simpler molecules that can ...
... Wastewater-based epidemiology (WBE) has become popular to estimate the use of drugs of abuse and recently to establish the incidence of CoVID 19 in large cities. However, its possibilities have been expanded recently as a technique that allows to establish a fingerprint of the characteristics of a city, such as state of health/disease, healthy/unhealthy living habits, exposure to different types o ...

Abstract:
... The dataset provides information on Pharmaceutical and Personal Care Products (PPCPs) detected in the Albufera Natural Park (Valencia, Spain), a typical Mediterranean coastal wetland. These PPCPs constitute an important group of organic pollutants highly representative of the human impact.The concentrations values measured in soil, sediment and water and the statistical relationship of contaminant ...
... The present study focused on the occurrence, distribution and risk assessment of 32 pharmaceuticals and personal care products (PPCPs) in water and sediment, as well as the surrounding soil of the irrigation channels and lake of a Mediterranean coastal wetland, the Albufera Natural Park (Valencia, Spain). Moreover, the influent and effluent of ten wastewater treatment plants (WWTPs) that treat was ...
chromatography; environmental science; evolution; mass spectrometry
Abstract:
... The coupling of chromatography to mass spectrometry has been a very important step in environmental science that has changed routine workflows opening a horizon of new and impressive possibilities. This hyphenated technique benefits from coupling as chromatography offers great separation power and comprises various techniques and mechanisms. In turn, chromatography exploits the identification capa ...
... In this study, the occurrence of 12 organophosphorus flame retardants (OPFRs), 64 pesticides, 21 perfluoroalkyl substances (PFASs) and 34 pharmaceuticals and personal care products (PPCPs) in surface water, sediments and vegetation collected from seven locations along the South Riyadh and six locations along the Al-Jubail industrial city (Saudi Arabia) were reported. The median of the concentratio ...
... In this study, water of the channels and ponds that conduct residual water in two most important cities of Saudi Arabia were assessed to ascertain the influence of the population on the occurrence and pollution characteristics of microplastics (MPs) (> 20 µm in size). Riyadh has 7.6 million inhabitants and is an urban city even though also have industry while Al-Jubail has only 0.78 and is the big ...
... Coastal environments are heavily influenced by human activities. Chemical substances considered as emerging contaminants (ECs) are one of the most important indicators of the anthropic influence on the environment, and they have recently shown to interact with microplastics (MPs). Mussels are suitable for in-lab bioacumulation studies providing insight about the occurrence and fate of contaminants ...

Abstract:
... This study assesses the extraction of eleven pharmaceuticals, five pesticides, five perfluoroalkyl substances, and two illicit drugs in hemolymph from (Mytilus Galloprovincialis). Four extraction procedures using Phree™ Phospholipid Removal cartridges were tested using different volumes of methanol (400 and 600 μL) and acetonitrile (300 and 450 μL). The pollutants were determined by high‐performan ...
... One of the aspects considered about the presence of contaminants in the aquatic ecosystems is their possible effect on critically endangered species, as the case of European eel, Anguilla anguilla. However, there is a lack of analytical methods to determine these contaminants due to the complexity of eel matrix (contains 5–20 % of lipids and 5–15 % of proteins). Thus, a multi-residue method using ...

Abstract:
... This study aimed to develop multi-residue methods for the extraction of organic pollutants in mussels (Mytilus galloprovincialis), including 11 pharmaceuticals, 5 pesticides, 5 perfluoroalkyl substances (PFASs) and 2 illicit drugs. The combination of 4 different QuEChERS methods and 12 clean-ups (a total of 44 combinations) was tested. QuEChERS included acidified (AQ), non-acidified (SQ) and their ...
... Water bodies cover approximately 70 % of the earth´s surface, making them ecosystems with a high environmental value and the habitat for numerous species of flora and fauna. Emerging pollutants (EPs) are ubiquitous anthropogenic compounds of environmental concern that can be found at different concentration levels in matrices such as sediment, water and aquatic biota. In addition, EPs can be bioac ...

Abstract:
... Two solid-phase extraction methods were systematically studied to determine 32 pharmaceuticals and personal care products in water and sediments by ultrahigh-performance liquid chromatography–tandem mass spectrometry. One involves HLB cartridges activated with sodium dodecyl sulfate before the passage of the sample to form an ion pair with cationic analytes, and the other uses mixed HLB–cation exc ...
... Pressurized liquid extraction (PLE) is a tool able to provide green extraction methods to further determine contaminants in food and the environment. The aim of this review is to offer a critical overview of the recent developments within this field and can be considered as an update of the previous that we published in 2015. Trends regarding sample treatment, solvents, in-cell clean-up approaches ...
... Wastewater-based epidemiology (WBE) has been consolidated as a tool to provide real-time information on consumption of legal and illegal drugs of abuse by the population. However, WBE is expected to achieve more ambitious objectives such as establishing exposure to certain agents (pesticides, personal care products, persistent organic pollutants, and pathogens), incidence of specific diseases (dia ...
