The degradation of the pharmaceutical compound ibuprofen (IBP) in aqueous solution induced by direct photolysis (UV‐A and UV‐C radiation) photocatalysis (TiO 2 /UV‐A TiO /UV‐C systems) was evaluated. Initially, we observed that whereas (both with radiation were able to cause an almost complete removal IBP, mineralization rates achieved for all photodegradation processes much smaller (the highest value being obtained system: 37.7%), even after exposure time as long 120 min. Chemical...
This work investigated the occurrence of pharmaceuticals and endocrine disrupting compounds (EDCs) in raw sewage (from Belo Horizonte city, Minas Gerais state, Brazil) assessed their behavior demo-scale upflow anaerobic sludge blanket reactors (UASB reactors) operated at different hydraulic retention times (HRT). The dissolved concentration studied micropollutants treated was obtained using solid phase extraction (SPE) followed by analysis a liquid chromatography system coupled to hybrid...
Some organic microcontaminants, known as endocrine-disrupting compounds (EDC), are frequently found in surface waters and of concern because their ability to alter the normal functioning endocrine system. In this study five these EDCs (estradiol, ethynylestradiol, bisphenol A, nonylphenol diethylphthalate) water samples, collected at upper part Rio das Velhas river (located between Ouro Preto Nova Lima, Minas Gerais state, Brazil) were analysed. The analytical methodology, which employed...
Endocrine disrupting compounds (EDCs) have attracted the attention of scientific community because effects EDCs on aquatic fauna and potential threat they pose to human health. There are a handful papers monitoring in Brazilian surface waters, hence this research was aimed at assessing, by using liquid chromatography coupled mass spectrometry (LC–MS), presence 17β‐estradiol, 17α‐ethynylestradiol 4‐nonylphenol waters used for supplying Belo Horizonte Metropolitan Area, Minas Gerais state,...
Environmental bisphenol A (BPA) contamination is currently a matter of concern. This compound can disrupt the endocrine system by mimicking natural hormones and cause adverse effects on different organisms. In addition, it has been suggested that BPA impair brain development, especially in fetuses children. To efficiently remove from contaminated water wastewaters, several emerging technologies have developed. Most are based photodegradation. However, by-products resulting application such...
Metformin (MTF) is the most widely prescribed drug for treatment of patients with type 2 diabetes. Studies involving removal MTF from aqueous solutions and detailed information regarding overall degradation process are scarce.The in solution induced by direct photolysis, photocatalysis, ozonation chlorination was evaluated. The continuously monitored focusing on identification monitoring by-products formed applying high-performance liquid chromatography coupled to high-resolution mass...
The presence of pharmaceuticals in water is a worldwide concern due to potential damage human and environmental health. For example, compounds such as the β-blocker atenolol (ATE), widely used for treatment cardiac disease, are detected drinking since conventional plants not designed remove them. Thus, evaluation ATE removal at different oxidative processes, identification its degradation products their toxicity necessary.Aqueous solutions (10 mg/L) were submitted treatments chlorination...
Antibiotics and their degradation byproducts are a relevant group of contaminants emerging concern. Conventional wastewater treatment plants fail to remove them. Thus, uncontrolled disposal antibiotics in the environment increases spread antibiotic-resistant bacteria genes. The present work describes development validation an analytical method for simultaneous determination three antibiotics—sulfamethoxazole (SMX), sulfadiazine (SDZ), trimethoprim (TMP)—in sewage sludge. is based on...
Contaminants of emerging concern are organic compounds used in large quantities by the society for various purposes. They have shown biological activity at low concentrations, which gives great environmental relevance. The difficulty to detect and quantify contaminants environment stimulates development appropriate analytical methods. In this work a chemometric approach positive negative electrospray ionization (ESI) optimization simultaneous determination water samples liquid...
DETERMINATION OF ETHYL CARBAMATE IN SUGAR CANE SPIRITS BY GC-MS.A simple, specific and sensitive GC-MS procedure with ion m/z 62 was validated for the determination of ethyl carbamate (EC) in spirits.It exhibited linearity over concentration 30 to 600 µg/L limit quantification.EC detected 70 71 samples analyzed levels from 33 2609 (mean level = 893 µg/L).35% contained 500 1000 23% 150 1500 µg/L.No significant correlation found between EC copper, pH alcohol content samples.
