“…Certain antibiotics were found to persist after manure storage and application on agricultural fields, and consequently, they could eventually leach into groundwater [17]. Once released, these contaminants, despite being polar and ionizable, could also persist in the soil matrix for long periods and, consequently, adversely affect microbes, worms, and other soil organisms [1].…”

The growing use of reclaimed water in agriculture worldwide calls for developing high-sensitivity methods to quantify wastewater-derived organic contaminants in soils so that the potential risk of this irrigation practice can be properly assessed. This work describes an analytical method for the determination of trace levels of 14 drugs that are known to be poorly removed during conventional wastewater treatment in soil. The analytes selected for investigation included ten pharmaceuticals from different therapeutic classes (carbamazepine diclofenac, cis-diltiazem lamotrigine, methadone, midazolam, oxcarbazepine, sulfamethoxazole, trimethoprim, valsartan), one illicit drug (cocaine), and three transformation products/metabolites (acridone, 4′hydroxydiclofenac, and valsartan acid), thereby covering a broad range of physical-chemical properties. The methodology developed was based on ultrasonic solvent extraction (USE) of the analytes from the soil matrix, and subsequent clean-up and analysis of the USE extracts with a fully automated approach by means of solid-phase extraction and liquid chromatographytandem mass spectrometry detection (online SPE-LC-MS/MS). The method was fully validated with affording method detection and quantification limits ranging from 0.03 to 1 ng g −1 and from 0.09 to 3.3 ng g −1 , respectively. This method was applied to investigate the fate of the selected drugs in potting soil irrigated for a long term (60 days) either with water containing the target compounds at a concentration of 200 μg L −1 or with wastewater treatment plant effluent and thus, at real environmental concentrations. All investigated compounds were found to accumulate in soil irrigated with artificially fortified water. The highest accumulation potential was observed for cis-diltiazem followed by methadone and midazolam that presented average concentrations of 1517 ng g −1 , 1041 ng g −1 , and 962 ng g −1 d.w., respectively. On the contrary, oxcarbazepine (5.8 ng g −1) and sulfamethoxazole (22 ng g −1) were the target drugs presenting the lowest accumulation potential. Only trace levels of ten drugs were measured in soil irrigated with regenerated water (average concentrations between 1.6 and 4.7 ng g −1 d.w.).

“…195 Estes, frequentemente denominados micro e nanopoluentes (em razão das suas concentrações ng ou µg kg -1 ou L -1 ) incluem, pesticidas, nanopartículas manufaturadas e fármacos, entre outros. 196 Muitos estudos vêm sendo desenvolvidos sobre estes contaminantes em solos de regiões temperadas sobre sua mobilidade e sua biodisponibilidade, destinados a modelar seu comportamento e prever a sua concentração e toxicidade em solos. Entretanto, em razão de diferenças fundamentais relativas à química dos solos de regiões tropicais e subtropicais (baixa atividade das argilas minerais, baixo teor de matéria orgânica, baixo pH, alto teor em óxido/hidróxidos de Fe) estes modelos são raramente aplicáveis para solos destas regiões.…”

ENVIRONMENTAL CHEMISTRY IN BRAZIL IN 40 YEARS IN THE SBQ. This paper aims to present an overview of the ongoing of the Brazilian environmental chemistry over the last forty years inserted in the context of the Brazilian Chemical Society (SBQ). Initially, a brief history presents the main milestones and premise of its "birth" in the 1980s, as well as the set of major actions taken within the SBQ to consolidate and strengthen this area of research. Then, in a separated approach between atmosphere, hydrosphere and lithosphere, we present the evolution of the main topics covered in Environmental Chemistry in Brazil, as well as the contribution of the chemists in the interdisciplinary scenario that constitutes this area. Finally, an overview of the evolution of the teaching of Environmental Chemistry in Brazil is presented.Keywords: environmental chemistry, atmosphere, hydrosphere, lithosphere, HISTÓRICO DA QUÍMICA AMBIENTAL NO BRASILNo Brasil, a Química Ambiental se desenvolveu a partir de um vínculo estreito com a Química Analítica, que se consolidou com base em uma escola consolidada e tradicional, com uma visão clássica sobre seu papel e voltada, em primeira instância, para o desenvolvimento de protocolos analíticos e elucidação de problemas estabelecidos dentro do laboratório. Portanto, boa parte dos primeiros químicos ambientais tinha uma forte ligação com a Química Analítica e eram poucos aqueles com experiência em trabalhos de campo e amostragem ambiental. Nos anos 1980, a pesquisa em Química Ambiental conduzida em nosso país tinha como base o monitoramento de espécies químicas presentes na hidrosfera, atmosfera e biota.1 Existem documentos evidenciando a escassez de atividades de pesquisa dedicadas ao estudo da reatividade química e comportamento de poluentes não apenas nos três compartimentos mencionados anteriormente, mas igualmente em suas interfaces.2 Estas circunstâncias resultaram em um desenvolvimento mais lento da Química Ambiental brasileira, quando comparada com a de outros países, especialmente os desenvolvidos. Não obstante estes aspectos, nos dias atuais a Química Ambiental ocupa posição de destaque no cenário científico nacional, tendo igualmente alcançado projeção internacional. Vários eventos científicos também têm contribuído para isso, tais como as Reuniões Anuais da Sociedade Brasileira CENÁRIO DE ESTUDO DA QUÍMICA AMBIENTAL NO BRASILPara contemplar o cenário das pesquisas em Química Ambiental no Brasil, decidimos dividir os estudos em hidrosfera, atmosfera e litosfera, embora estes compartimentos sejam integrados e não haja um mais importante que o outro e tampouco podem ser vistos separadamente. Além disso, este texto não tem a pretensão de fazer uma revisão exaustiva das publicações nestas áreas dentro da Química Ambiental, mas sim de apresentar um panorama da evolução e dos temas que foram e estão sendo estudados nestes 40 anos da Sociedade Brasileira de Química, apresentando exemplos de alguns destes trabalhos.

“…For about thirty years, the concern about the amount of organic contaminants that can be found in various environmental compartments has grown [1][2][3], as massively used pharmaceutical compounds (PCs) have been continuously introduced in the environment over time. In addition to unused medication and pharmaceutical manufacturing plants and hospitals discharge, a large fraction of consumed human or veterinary active compounds are expelled from the body after a short period of time and end up in municipal sewage systems and wastewater treatment plants [4][5][6][7][8][9].…”

Adsorption of Pharmaceuticals onto Smectite Clay Minerals: A Combined Experimental and Theoretical Study

et al. 2021

View full text Add to dashboard Cite

The adsorption of two pharmaceuticals, carbamazepine and paracetamol, onto the expandable clay mineral saponite has been studied through the combination of kinetic experiments, X-ray diffraction, and theoretical modeling. Kinetic experiments indicate low adsorption for carbamazepine and paracetamol on expandable smectite clay. Accordingly, X-ray diffraction experiments show that neither compound enters smectite interlayer space. Molecular dynamics simulations were carried out to understand the interactions between the two pharmaceuticals and the saponite basal surface in the presence of Na+ cations. Calculations reveal that paracetamol almost does not coordinate solution cations, whereas a rather low coordination to cation is observed for carbamazepine. As a result, the adsorption onto the clay surface results mainly from van der Waals interactions for both pharmaceuticals. Carbamazepine does adsorb the surface via two configurations, one involving cation coordination, which corresponds to a rather stable adsorption compared to paracetamol. This is confirmed by structural analyses completed with desorption free energy profile.
