L'Albufera Natural Park (Valencia, Spain) is a protected wetland of international significance that provides critical habitats to endemic and threatened bird and plant species. This study aims to use multiple cross-validation techniques to generate an accurate estimation of the environmental risk of organic contaminants (OCs) in an internationally...
Microplastics (MPs) form the most investigated plastic category since their size (1 μm- 5 mm) enables them to accumulate in various environmental compartments and to be ingested by biota. Beach sand and sediment can be indicators of the MP contamination levels of the coastal and marine ecosystem and, thus, they are widely analyzed. With the increas...
Microplastics (MPs) are in all environmental compartments, including atmosphere, terrestrial, and aquatic environments as well as in marine organisms, foods, drinking water, and indoor and outdoor environments. MPs can enter the human body through the food chain and contaminated environment. Ingestion, inhalation, and dermal contact are the routes...
Gestation is a crucial life stage for both women and offspring, and outcomes are affected by many environmental factors, including diet. The Mediterranean dietary pattern (MD) is considered a healthy eating pattern that can provide the nutritional requirements of pregnancy. Meanwhile, iron deficiency anemia is one of the most frequent complications...
Recently, environment pollution around the globe has increased because of anthropogenic activities. As part of the biota, plants can assimilate the compounds present in air, water and soil and respond to changes in surround conditions, for that, they can be used as bioindicators of global pollution. However, urban plants' ability to monitor organic...
Wastewater-based epidemiology (WBE) approach provides objective, quantitative, near real-time profiles of illicit drug consumption by monitoring the concentration of unchanged parent drugs or their metabolites entering the municipal sewage system. Valencia is the third most populous city in Spain (an important country for the use and transit of sev...
According to UNEP and FAO reports, the fishing nets abandoned in the seas around the world represent approximately 10% of the plastic waste present in the oceans. These nets, also called ghost nets, can be degraded over time, releasing microplastics and contaminating the environment. Studying the presence and amount of microplastics in an area impa...
Considering current water situation, reuse is an effective solution to meet water demand and reduce pressure on conventional water sources. However, pharmaceutical and personal care products (PPCPs) in effluents from wastewater treatment plants (WWTPs) decrease their quality and suitability. With the aim of identifying and monitoring both the influ...

Pyrolysis–gas chromatography–mass spectrometry (Py–GC–MS) has confirmed to be a versatile technique that benefits food and environmental analyses. It has been used for the chemical characterization of materials and compounds that are not suitable for traditional gas chromatography (GC) because of their large size. The controlled thermal degradation...
Isotope ratio mass spectrometry (IRMS) measures small differences in the abundances of light-stable isotopes of elements, mostly carbon, hydrogen, oxygen, sulfur, and nitrogen. The ratio of isotopes is dependent on the environment where the samples are located and therefore the measurement of the isotope signature in food and environmental samples...
Mass spectrometry (MS) has achieved great renown as a specific, selective, sensitive, and rapid technique for the analysis and evaluation of a wide range of food products and environmental matrices. The state of the art of MS in food and environmental safety and quality is presented to show the potential of this technique in the qualification and q...
The spread of pesticides in water bodies integrated into agricultural landscapes may prevent some areas from being colonized. In this study, the effects on the colonization responses of D. magna exerted by gradients of realistic environmental concentrations of the pesticides chlorpyrifos, terbuthylazine and their mixtures were tested in a novel mul...
Worldwide regulatory agencies should (re)examine the consideration of: (i) sub-threshold responses, (ii) non-linear dose-response models able to detect sub-threshold responses of both a beneficial and detrimental nature, and (iii) abandoning the use of default dose-response models for their risk assessment. Mounting evidence for significant sub-thr...
There are numerous families of perfluoroalkyl and polyfluoroalkyl substances (PFASs), consisting of a series of homologues and branched isomers. Special attention is required for collecting and preparing samples for analysis since PFASs are ubiquitous, and can be present in any plastic or waterproof material used during sampling. PFASs in air might...
The profiling of emerging organic pollutants present in sludge and generated during wastewater treatment is much more limited than in water. This is mainly due to the difficulty of sludge analysis because of its high content of organic matter and interfering compounds. In this study, a generic extraction method using a mixture of buffered water (pH...
In this chapter we review the available data on the application of non-targeted high-resolution mass spectrometry (HRMS) analysis to identify a wide range of substances (mainly emerging pollutants) present in sludge.

The concept of wastewater-based epidemiology (WBE) also known as sewage epidemiology, was proposed by Daughton in 2001. WBE 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 microorgani...
Pharmaceuticals and personal care products (PPCPs) are abundantly used by people, and some of them are excreted unaltered or as metabolites through urine, with the sewage being the most important source to their release to the environment. These compounds are in almost all types of water (wastewater, surface water, groundwater, etc.) at concentrati...

The use of some systemic insecticides has been banned in Europe because they are toxic to beneficial insects when these feed on nectar. A recent study shows that systemic insecticides can also kill beneficial insects when they feed on honeydew. Honeydew is the sugar-rich excretion of hemipterans and is the most abundant carbohydrate source for bene...

MPs can also absorb organic contaminants, and can be ingested by organisms and introduced into the food web. MPs can be a vector...
Significance
The use of insecticides in agriculture is one of the suggested causes of the decline in insect populations. Neonicotinoids are among the most widely used insecticides. However, they have important negative side effects, especially for pollinators and other beneficial insects feeding on floral nectar and pollen. We identified an exposur...
