Salinomycin sodium (BIO-COX) is polyether ionophore, commonly used in the poultry industries for the prevention of coccidial infections and promotion of growth. Salinomycin sodium (SAL-Na) is very toxic, and may be fatal, if swallowed, inhaled, or absorbed through the skin than many other antibiotics, thus evaluating their fate in the soil environment is of importance. Sorption of SAL-Na was measured in clay, loamy sand, and sandy soil at different pH 4, 7, and 9, and desorption with phosphate buffer (pH 7) using batch equilibration technique. SAL-Na was sorbed by all the soils studied, the sorption of SAL-Na by the sandy soil increased as the pH decreased, while the sorption of salinomycin in clay and loamy sand soil increased as the pH increased. Desorption of salinomycin from the soil with phosphate buffer (pH 7) over the 24 h period was 80-95% of the amount added. The similar trend was observed in desorption with pH 4, 7 and at different concentrations and slight less desorption was observed in pH 9. When compared to clay and loamy sand soil, sandy soil was recorded maximum (95%) desorption.
Sesuvium portulacastrum is a salt hyper accumulating plant and pioneer plant species used for desalination and phytoremediation. The plant tolerates abiotic constraints such as salinity and drought. It grows under severe salinity and it can be used for the remediation and restoration of salt contaminated soils affected from industrial effluents. Among the major water demanding industries, the textile industry has biggest impact on the environment related to primary water consumption and waste water discharge. Textile effluent has a large range of organic chemicals of high salinity, high colour and low biodegradability. Salinity exerts negative effects on plant growth and affects the biological stability of ecosystems.The experiment on salt uptake through salt enrichment study was conducted and also to assess the potential of Sesuvium portulacastrum collected from Pitchavaram in Chidambaram District of Tamil Nadu, India for the remediation of dye and textile contaminated area in Andipalayam, Mangalam and Palayakottai villages of Tirupur District of Tamil Nadu was studied upto 70Days After Planting (DAP). The results of the soil analysis revealed that, the initial EC of soil 13.04 dSm -1 is reduced to 7.37 dSm -1 (30 Days after planting (DAP) and 5.34 dSm-1(60DAP). The plant shoot length and root lengths were increased to 74% and biomass was increased to 94% in 5000mg/kg of Na enriched soils. The electrical conductivity and sodium content were decreased in Sesuvium grown soil enriched with different concentrations of Na. 77.8% of Sodium was removed from the soil in a span of 90 days.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
