“…Instead, the combination of two or more PPCPs has demonstrated less intense biological responses than single contaminant exposures in both lab and field experiments. ,,, Most of these studies are designed with static mixtures that remain constant in composition of constituents over space and time. As new pharmaceuticals rapidly enter market consumption relative to environmental study of contaminants, we suggest the initiation of new field studies focusing either intensively within individual systems or extensively across landscape scales in order to capture the breadth of PPCP mixtures encountered as well as the associated biological responses. − Such studies may lack the experimental control of dose–response studies, but can help reveal the relative composition and diversity of mixtures experienced by organisms in the environment as well as identify regional patterns of PPCP occurrence and concentrations. When combined with co-located biological measurements, PPCP data from field studies could be used to infer relationships between observed PPCP mixtures and biotic responses across multiple spatial scales.…”

Pharmaceuticals and personal care products (PPCPs) garner increasing attention globally for both their usefulness as indicators of human waste and their potency as emerging organic toxicants. Three decades of rapid increase in PPCP study combined with an increasing number of PPCPs on the global market have created an opportunity (1) to review trends in diversity of compounds, sewage treatment techniques (STTs), and ecosystems investigated as well as (2) to identify knowledge gaps in the literature. We conducted a quantitative evidence synthesis of 6517 abstracts from primary articles in the environmental PPCP literature by examining relative abundance of specific PPCP classes, STTs, and ecosystem types. Our results demonstrate that non-prescription drugs and antibiotics dominated PPCP abstracts, appearing in 51% and 39% of reviewed abstracts, respectively, in comparison to hormones (18%), prescription drugs (18%), fragrances (0.3%), and antioxidants (0.0%), which can all elicit physiological and ecological responses even at low concentrations. References to centralized STTs (e.g., activated sludge, 37%) were more frequent than decentralized STTs (e.g., septic, 2%), despite decentralized STTs being common and frequently high impact sources of sewage pollution worldwide. Freshwater lotic systems (63%) were more prevalent than freshwater lentic (24%) and terrestrial (20%) systems. This discrepancy is notable because the longer residence times of lentic and terrestrial systems may enable PPCPs to concentrate and thus increase risk of biological consequences. These results highlight distinct opportunities to address knowledge gaps in the environmental PPCP literature, including underrepresented compounds (e.g., fragrances), sewage treatment techniques (e.g., septic systems), and ecosystem types (e.g., lakes).

“…β-Lactam antibiotics are often detected in biological sludge from WWTPs at a very low concentration. For example, amoxicillin (AMX) and ampicillin (AMPI) concentrations of 1.0 and 14.8 μg/kg dry wt, respectively, were reported in biological sludge collected from municipal WWTPs . The β-lactam ring is highly unstable and easily cleaved by β-lactamases, a group of enzymes widely excreted by bacteria. ,, Notably, studies on transformation and fate of β-lactams in biological wastewater treatment systems showed that the removal routes for major antibiotics in this class, including AMX, AMPI (penicillin), and cephalexin (CEFX) (cephalosporins), varied greatly, possibly due to their different chemical structures, such as variable side chains.…”

Antibiotics, the most frequently prescribed drugs of modern medicine, are extensively used for both human and veterinary applications. Antibiotics from different wastewater sources (e.g., municipal, hospitals, animal production, and pharmaceutical industries) ultimately are discharged into wastewater treatment plants. Sorption and biodegradation are the two major removal pathways of antibiotics during biological wastewater treatment processes. This review provides the fundamental insights into sorption mechanisms and biodegradation pathways of different classes of antibiotics with diverse physical–chemical attributes. Important factors affecting sorption and biodegradation behavior of antibiotics are also highlighted. Furthermore, this review also sheds light on the critical role of extracellular polymeric substances on antibiotics adsorption and their removal in engineered biological wastewater treatment systems. Despite major advancements, engineered biological wastewater treatment systems are only moderately effective (48–77%) in the removal of antibiotics. In this review, we systematically summarize the behavior and removal of different antibiotics in various biological treatment systems with discussion on their removal efficiency, removal mechanisms, critical bioreactor operating conditions affecting antibiotics removal, and recent innovative advancements. Besides, relevant background information including antibiotics classification, physical–chemical properties, and their occurrence in the environment from different sources is also briefly covered. This review aims to advance our understanding of the fate of various classes of antibiotics in engineered biological wastewater treatment systems and outlines future research directions.

“…Asimismo, los lodos residuales pueden contener diversos tipos de materiales inorgánicos como metales pesados, químicos, patógenos, bacterias, protozoarios, helmintos, entre otros. Esto causa que sea de gran preocupación la gestión que se les da a dichos residuos, ya que ponen en riesgo la salud y el medio ambiente (Castillo et al, 2020;Magee et al, 2018;Meng et al, 2016). No obstante, estos tienen un gran contenido de materia orgánica que generan frecuentemente, brindando así múltiples oportunidades de implementar modelos o estrategias de reutilización (Bora et al, 2020).…”

“…En la actualidad, uno de los principales retos que enfrentan las empresas que prestan servicios como los de acueducto y alcantarillado, es el método que deben usar para realizar la adecuada disposición de los lodos que se generan como subproducto, pues estos representan una importante fuente de contaminación (Magee et al, 2018;Utria-Borges et al, 2008). Sin embargo, la disposición final de los lodos genera ciertos gastos económicos, puesto que requieren de la instalación de reactores o de sistemas de estabilización para el tratamiento.…”

Contextualización: el crecimiento demográfico y los problemas ambientales en el ámbito local, nacional e internacional, relacionados con la contaminación de los lodos sin tratar, debido a los volúmenes en aumento de dichos residuos generados por las estaciones depuradoras de aguas residuales (EDAR), aumenta la degradación del medio ambiente. Vacío de conocimiento: hay deficiencias en los manejos de los lodos residuales por desconocimiento de las alternativas convencionales y sostenibles de estabilización, lo que causa que estos no sean aprovechados, debido a sus características, y terminen siendo desechados en puntos de disposición final, lo cual puede generar severos problemas de contaminación. Propósito: evaluar la literatura científica sobre las alternativas implementadas en la estabilización de lodos residuales generados en las EDAR, mediante una revisión documental y un análisis bibliométrico basado en la construcción de diagramas estratégicos y mapa de co-ocurrencia, con el fin de identificar las tendencias de investigación en la temática. Metodología: se indagó la literatura científica mediante un algoritmo de búsqueda con conectores booleanos en la base de datos especializada Scopus®, la cual se analizó mediante redes bibliométricas y diagramas estratégicos y se ordenó una base de datos con la información relevante para el análisis conceptual sobre la temática. Resultados y conclusiones: se obtuvieron 1693 documentos enmarcados en las alternativas de estabilización de biosólidos provenientes de las EDAR, lo que permitió identificar que países como Estados Unidos, China, Brasil y España poseen la mayor producción científica sobre la temática. La generación de biosólidos es una problemática que ha fundamentado investigaciones para la gestión adecuada de estos residuos, para así evitar generar problemas de contaminación, dado que las alternativas convencionales más empleadas para el tratamiento de biosólidos son la digestión anaerobia, el espesamiento, la deshidratación y la incineración, que son eficientes en la gestión, pero desaprovechan el potencial de dichos residuos. Las alternativas como el compostaje y la lombricultura generan subproductos que se pueden aprovechar y de esta forma lograr una disposición final de manera adecuada, que reduzca los costos operacionales y genere beneficios económicos.
