“…A zeolite with a higher content of the more hydrophobic silicon can show higher affinity for nonpolar organics [223,224]. Some of the synthetic zeolites for which studies can be found in the literature are the beta (BEA) zeolite [221,223,225], ZSM-5 [211,[221][222][223], hydroxysodalite [226], zeolite A (LTA) [224,227], zeolite P [226], zeolite X [224,227], zeolite Y [222,224,228,229] and dealuminated Y (DAY) zeolite [230][231][232].…”

“…There are several examples of biomedical applications of zeolites reported in the literature for wound treatment [15], herbicide release [16], and drug adsorption from polluted waters [13,[18][19][20][21][22] including sulfonamide antibiotics [17][18][19]. Also, stable formation of hybrid assembly between zeolite (type L) and bacteria (E. coli) was realized and the exchange of specific information as well as the movement of the bacterium has become possible.…”

by Solid-state Ion Exchange (SSIE) procedure over zeolite Y, followed by deposition of sulfadiazine (SD) by dry mixing was examined for the preparation of topical antibacterial formulations. The ion-exchange and adsorptive properties of the zeolite matrix were utilized for the bactericidal Ag deposition and loading of antibiotic sulfadiazine.Experiments: Assessment of the encapsulation efficiency of both active components loaded by solid and liquid deposition methods was made by X-ray diffraction, TEM, FT-IR spectroscopy and thermogravimetric analysis (TGA). SD release kinetics was also determined.Findings: Sustained delivery of sulfadiazine has been observed from the Ag-modified zeolites compared to the parent HY material. It was found that if SD was loaded in solution, part of the zeolite silver ions was released and interacted with SD, forming AgSD. By solid-state SD deposition, the reaction between the drug and the silver was restricted within the limits of inter-atomic interaction, and total but prolonged drug release occurred.

“…Sulfonamides (SA) are extensively used pharmaceuticals with antibacterial activity against a large range of infectious agents by competitively inhibiting the use of p-aminobenzoate in the biosynthesis of folic acid (Braschi et al, 2010;Michelini et al, 2012). Sulfonamides are commonly administered in the treatment of respiratory and urinary infections and in animal husbandries are used for prophylactic and therapeutic purposes (Boreen et al, 2004;Sarmah et al, 2006).…”

“…bacteria, microalgae, plants, invertebrates and fish) include acute and chronic effects demonstrated in inhibition of growth (Brain et al, 2004;Baran et al, 2006;Kim et al, 2009;Ji et al, 2012). Due to SA's amphoteric nature the extent to which the current filtering systems and depuration actions can prevent their release to the environment is strongly related with their sorption capacity, which in turn is dependent on soil/ sediment composition and pH (Halling-Sorensen et al, 1998;Kahle and Stamm, 2007;García-Galán et al, 2008;Lertpaitoonpan et al, 2009;Braschi et al, 2010;Hruska and Franek, 2012).…”

The influence of sulfathiazole on the macroalgae Ulva lactuca

h i g h l i g h t sSulfathiazole shows high stability in seawater with 18% degradation over 5 d. Ulva lactuca reduced the concentrations of STZ in the water by efficiently taking up the drug. U. lactuca kept the internal values constant most likely through a detoxification mechanism. Sulfathiazole slightly inhibited the growth of U. lactuca after 96 h of exposure. Macroalgae should be considered as potential bioindicator species in risk assessment of STZ. Sulfonamides (SA) are a class of antibiotics routinely found in environmental matrices and therefore their role as contaminants should be investigated in non-target organisms. With this purpose the present experimental work has evaluated the exposure of the chlorophycean Ulva lactuca L. to sulfathiazole (STZ), a SA drug commonly used in aquaculture, at two concentrations representing prophylactic (25 lg mL À1 ) and therapeutic (50 lg mL À1 ) administrations. Results showed that STZ exhibits high stability in seawater with only 18% degradation over the 5 d assay at both dosages tested. Also, macroalgae demonstrated an efficient uptake capacity with constant internal concentrations after 24 h regardless of the external solutions and thus should be considered as a bioindicator species in risk assessment. Both STZ concentrations induced a slight inhibition of the macroalgae growth after 96 h. a r t i c l e i n f o
