“…Com o maior consumo de medicamentos, tanto pela indústria agropecuária como pela população, fármacos vêm sendo encontrados mais frequentemente em estações de tratamento de esgotos e águas superficiais. 1,2 O principal meio de aporte de fármacos no ambiente aquático ocorre através das estações de tratamento de esgoto (ETEs), estes compostos orgânicos, bem como seus metabolitos podem permanecer inalterados mostrando-se resistentes ao tratamento, assim como podem ser parcialmente ou completamente degradados. 3 O alprazolam (ALP), é um contaminante emergente e pertence a um grupo de substâncias denominado benzodiazepínicos (BDZs), que são fármacos ansiolíticos que atuam sobre o sistema nervoso central (SNC) e possuem efeitos sedativos e hipnóticos.…”

The presence of drugs in aquatic environments is an emerging problem, since the removal of drugs in conventional water and sewage treatment systems has not shown to be efficient. The application of alternative adsorbent materials may be a resource to be exploited in economically viable treatment processes. Materials that are normally discarded in nature, such as industrial waste, can be reused in treatment systems, improving their efficiency and adding value to industrial waste. Examples of these are boiler shell residues, Resíduo de casca de caldeira (RCC) in Portuguese, which is a non-activated carbonaceous material, from the burning of biomass to generate heat, and a residue generated in the process of bleaching chewable candies (activated charcoal of pinus with diatomaceous earth, carvão ativado pulverizado de pinus com terra diatomácea-DT, 70:30 in portuguese) used in food industries. In this work, we sought the removal of Alprazolam in aqueous media through the use of these adsorbent materials. The adsorbents were characterized as their physico-chemical properties and adsorption studies in batch and fixed bed columns were performed to evaluate their efficiency. The results obtained for the characterization were: Surface area of the CAPP / TD: 217.4 m 2 g-1 and the RCC of 349.54 m 2 g-1 , both presented pHpcz above of 8 and basic pH. The CAPP / TD presented higher particle sizes, lower iodine number and higher amount of ash when compared to RCC. The batch studies showed ALP removal of 69 % in 60 min and 85 % in 90 min for RCC and CAPP / TD, respectively. The best conditions for the removal of ALP in fixed bed were pH = 6; T = 30 °C; V = 1.3 mL min-1 for RCC and pH = 4; T = 25 °C; V = 0.56 mL min-1 for CAPP / TD. For both residues, no matrix interference was observed. The study demonstrated that both adsorbents were efficient for the removal of ALP, and can be applied for the treatment of the environmental aqueous samples.

“…Diversified impact of micropollutants on several indicator organisms makes it difficult to determine safe concentrations of those chemicals that do not cause adverse changes in the entire ecosystem. Hardly biodegradable compounds often require the use of advanced methods for their decomposition, which can enhance the water toxicity [6,7].…”

Abstract. The paper presents the toxicological analysis of water solutions of micropollutants from different groups i.e. industrial additives, pharmaceutical compounds, hormones, UV blockers and pesticides before and after their exposure to UV light. The toxicological response of both Microtox ® and Daphtoxkit F ® test, increased with the increase of the compound concentration. Triclosan water solution was considered as the most toxic. The lowest toxic effect was observed for Imidacloprid and Octyl-methoxycinnamate solutions. The exposure of Benzocaine, Octyl-methoxycinnamate and Triclosan water solutions to UV light led to an increase of their toxicity. An inverse relationship was observed for Imidacloprid and 17α-Ethinylestradiol solutions.

“…[2][3][4] Therefore, the development and optimization of an analytical method for monitoring the concentrations of emerging pollutants in the environment would be of great utility. Although long-term ecotoxicological effects remain unclear, most of them are biologically active compounds which inevitably harm directly or indirectly the environment and humanity.…”

A sensitive and reliable method using a two-phase hollow fiber liquid-phase microextraction (HF-LPME) pretreatment technique was developed for simultaneously screening multiple b-blockers in environmental samples. In this study, heptanol was chosen as the optimal extraction solvent, and six bblockers with a wide range of polarities were extracted across the porous walls of hollow fibers and into the acceptor phase (AP). The fundamental parameters affecting the extraction efficiency (EE) of analytes including extraction time, temperature, pH of the donor phase (DP) and AP, stirring speed, volume of the sample solution, ionic strength and the type of hollow fiber membrane were studied and optimized.Under optimal conditions, extracts were analyzed by HPLC with ultraviolet detection (UV). Finally, satisfactory results were obtained, good linearity was observed for all b-blockers in the range of 0.16-200 ng mL À1 , limits of detection (LODs) were between 0.08 and 0.5 ng mL À1 , the intra-and inter-day precision values of the six b-blockers were 1.0-2.2% and 1.4-2.7%, respectively. The recovery with RSDs was less than 2.2% for the pretreatment method. The proposed technique was successfully applied for screening multiple b-blockers in complex aqueous samples with the best specificity and provided a simple and reliable new means for the self-checking of laboratories at the basic level.
