“…Depending on recent studies, the high level of many of pharmaceuticals in plant roots than plant leaves might be attributed to several factors, such as the concentration of pharmaceuticals in soil solution, pharmaceutical octanol-water partition coefficient, lipophilicity and physico-chemical characteristics of both pharmaceutical and soil (28)(29)(30). However, the lipophilic compounds could be taken up by plant roots through active and passive transport in high level in comparison to plant leaves.…”

The ability of beans (Phaseolus vulgaris L.) to uptake three pharmaceuticals (diclofenac, mefenamic acid and metronidazole) from two types of soil (clay and sandy soil) was investigated in this study to explore the human exposure to these pharmaceuticals via the consumption of beans. A pot experiment was conducted with beans plants which were grown in two types of soil for six weeks under controlled conditions. During the experiment period, the soil pore water was collected weekly and the concentrations of the test compounds in soil pore water as well as in plant organs (roots, stems and leaves) were weekly determined. The results showed that the studied pharmaceuticals were detected in all plant tissues; their concentrations in plant roots were higher than plant stems and leaves. The extent level and accumulation of the studied pharmaceuticals in sandy soil was higher than the clay soil. The concentration of diclofenac in plant tissues was higher than both of mefenamic acid and metronidazole, indicating that diclofenac is more available to plant. The content of dissolved pharmaceuticals in soil pore water decreased gradually over time during the experimental period confirming the ability of beans to uptake these pharmaceuticals from soil. The results suggest the possibility of studying pharmaceuticals to be accumulated in beans tissues despite their low concentrations in the studied soils.

“…The water solubility is corrected following Trapp and Matthies ( 1998 ) and K OW by calculating it as the fraction of octanol solubility and water solubility at pH 7. The protolysation calculations in the model were validated by building a Level I model environment simulating IBU partitioning pH dependency measurements by Hiller and Šebesta ( 2017 ) and comparing the results. Although low pH partitioning differed greatly, the results at pHs ≥ 5.8 agreed well, suggesting that the calculations are adequate for environmental applications.…”

An updated version of FATEMOD, a multimedia fugacity model for environmental fate of organic chemicals, was set up to assess environmental behaviour of three pharmaceuticals in northern Lake Päijänne, Finland. Concentrations of ibuprofen, diclofenac, and carbamazepine were estimated at various depths at two sites: near a wastewater treatment plant and 3.5 km downstream the plant. When compared with environmental sampling data from corresponding depths and sites, the predicted concentrations, ranging from nanograms to hundreds of nanograms per litre, were found to be in good agreement. Weather data were utilised with the model to rationalise the effects of various environmental parameters on the sampling results, and, e.g. the roles of various properties of lake dynamics and photodegradation were identified. The new model also enables simultaneous assessment of transformation products. Environmentally formed transformation product concentrations were estimated to be at highest an order of magnitude lower than those of the parent compounds, and unlikely to reach a detectable level. However, a possibility that conjugates of ibuprofen are present at higher levels than the parent compound was identified. Simulation results suggest that environmental degradation half-lives of the inspected contaminants under stratified lake conditions are in the range of some weeks to months.

“…O coeficiente de partição octanol--água (K ow ), indicador da hidrofobicidade de um contaminante, sofre uma redução com o aumento da temperatura, de magnitude variável de acordo com o tipo de composto (HULSCHER & CONERLISSEN 1996, COLOMBANO et al 2020. A solubilidade e o K ow estão diretamente associados à sorção do contaminante no meio; dessa forma, em temperaturas maiores os contaminantes tendem a ser menos retidos por sorção, sendo mais facilmente removidos do solo (BAHADUR et al 1997, TSE & LO 2002, BORRIRUKWISITSAK et al 2012, HILLER & ŠEBESTA 2017. Assim como a solubilidade, a taxa de difusão molecular FIGURA 1 -Faixas da temperatura de ebulição para diferentes classes de contaminantes.…”

“…A biodegradação dos contaminantes também pode ser favorecida com o aumento da temperatura, durante ou após o processo de remediação (HERON et al 2005). O aquecimento do solo em baixas temperaturas (aproximadamente 70 °C) pode favorecer as taxas de biodegradação de contaminantes como organoclorados e hidrocarbonetos de petróleo (HERON et al 2005, HORST et al 2018.…”

“…A utilização combinada da remediação térmica com outras técnicas, como a biorremediação, redução química in situ e até mesmo outros proces-sos térmicos, como a injeção de vapores associada ao ERH, também deve ser considerada num plano de remediação, a fim de torná-la mais sustentável. A combinação de técnicas diferentes pode aumentar a eficiência energética da remediação térmica e ampliar seu uso em áreas heterogêneas, como naquelas com grande variação de permeabilidade do solo, além de potencializar a remoção de massa dos contaminantes (HERON et al 2005, STROO et al 2012, HORST et al 2018.…”

Processos térmicos têm sido cada vez mais aplicados mundialmente para a remediação de áreas contaminadas. O tratamento térmico, in situ ou ex situ, baseia-se na elevação da temperatura do solo e da água subterrânea visando a degradação do contaminante ou a sua transferência para a fase vapor, facilitando sua extração. Existem diversas formas de aquecimento, sendo a condução de calor, o aquecimento por resistência elétrica e a injeção de vapor os métodos mais utilizados. A remediação térmica pode ser utilizada em áreas com concentrações elevadas de contaminantes dissolvidos e até mesmo em fase separada (NAPLs), além de ser aplicável em diferentes litologias. Apesar do seu potencial de utilização, no Brasil essa técnica ainda é pouco estudada e aplicada. Dessa forma, o presente trabalho apresenta uma análise das diversas técnicas de remediação por processos térmicos, suas aplicações, vantagens e desvantagens, assim como um panorama de sua utilização em nível nacional.
