Competitive adsorption and desorption of tetracycline and sulfadiazine in crop soils
In view of the environmental issues caused by antibiotics, this research studies competitive adsorption/desorption for tetracycline (TC) and sulfadiazine (SDZ) in agricultural soils. Competitive adsorption was studied in binary systems (adding equal concentrations of both antibiotics). In addition,...

| description | In view of the environmental issues caused by antibiotics, this research studies competitive adsorption/desorption for tetracycline (TC) and sulfadiazine (SDZ) in agricultural soils. Competitive adsorption was studied in binary systems (adding equal concentrations of both antibiotics). In addition, it was compared with results from simple systems. In all cases, batch-type adsorption/desorption experiments were carried out. In the binary systems, for the highest antibiotic concentration added, adsorption percentages were always higher for TC (close to 100%) than for SDZ (10–90%). In these systems, TC desorption was lower than 5% for all soils, and generally |

On the contrary, comparing the results of TC adsorption in simple and binary systems, TC was not affected by the presence of SDZ, obtaining similar adsorption percentages in both systems. Kd and KF values (in the Linear and Freundlich models), were higher in the simple systems in the case of TC, which could be due to competition with SDZ, while for SDZ Kd and KF were higher in the binary systems, with a synergistic effect of TC favoring SDZ adsorption. Regarding desorption, it reached 100% for SDZ in some soils in simple systems, dropping to 10% in the presence of TC. TC desorption was <4%, not affected by SDZ. The results indicate that environmental risks would be higher for SDZ, showing differences when both antibiotics are present. This can be considered relevant as regards public health and environmental preservation, in view of direct toxicities and the promotion of resistance to antibiotics associated with the presence of these contaminants in the environment.</description><identifier>ISSN: 0013-9351</identifier><identifier>EISSN: 1096-0953</identifier><identifier>DOI: 10.1016/j.envres.2022.113726</identifier><language>eng</language><publisher>Elsevier Inc</publisher><subject>Agriculture ; Antibiotics ; Emerging pollutants ; Release ; Retention</subject><ispartof>Environmental research, 2022-11, Vol.214, p.113726-113726, Article 113726</ispartof><rights>2022 The Authors</rights><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c385t-3d6fc3930c80854b2f99b43e98c6044b97a57a513b25de04dcb0a372f8a5ad813</citedby><cites>FETCH-LOGICAL-c385t-3d6fc3930c80854b2f99b43e98c6044b97a57a513b25de04dcb0a372f8a5ad813</cites><orcidid>0000-0003-2826-799X</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktohtml>$$Uhttps://dx.doi.org/10.1016/j.envres.2022.113726$$EHTML$$P50$$Gelsevier$$Hfree_for_read</linktohtml><link.rule.ids>314,780,784,3550,27924,27925,45995</link.rule.ids></links><search><creatorcontrib>Cela-Dablanca, Raquel</creatorcontrib><creatorcontrib>Barreiro-Buján, Ana</creatorcontrib><creatorcontrib>Ferreira-Coelho, Gustavo</creatorcontrib><creatorcontrib>López, Lucia Rodríguez</creatorcontrib><creatorcontrib>Santás-Miguel, Vanesa</creatorcontrib><creatorcontrib>Arias-Estévez, Manuel</creatorcontrib><creatorcontrib>Núñez-Delgado, Avelino</creatorcontrib><creatorcontrib>Fernández-Sanjurjo, María J.</creatorcontrib><creatorcontrib>Álvarez-Rodríguez, Esperanza</creatorcontrib><title>Competitive adsorption and desorption of tetracycline and sulfadiazine in crop soils</title><title>Environmental research</title><description>In view of the environmental issues caused by antibiotics, this research studies competitive adsorption/desorption for tetracycline (TC) and sulfadiazine (SDZ) in agricultural soils.
