Recebido em 17/5/12; aceito em 2/9/12; publicado na web em 1/2/2013 Hydrogen peroxide has been used for decades in developed countries as an oxidizing agent in the treatment of water, domestic sewage and industrial effluents. This study evaluated the influence of the concentration of H 2 O 2 and pH on the inactivation of Escherichia coli cells and the disinfection of sewage treated. The results showed that the inactivation rate increased with pH and H 2 O 2. The presence of other contaminants dissolved in the effluent is probably the cause of these differences, because E. coli inactivation in synthetic wastewater was found to be much faster than in the real treated domestic sewage.

“…The H 2 O 2 application inhibited the growth of Septoria tritici on wheat plants [30]. However, the effectiveness of H 2 O 2 depends on many factors, including concentration, exposure time, temperature, pH, and pathogen [31][32][33]. Bactericidal action is weaker compared to sporicidal action, but H 2 O 2 is bacteriostatic at concentrations above 0.5% [34].…”

The biocidal properties of hydrogen peroxide (H2O2) could be used in plant protection. However, the effects of H2O2 foliar spraying on the performance of the potato photosynthetic apparatus are still unclear. A pot experiment was conducted to investigate the effect of foliar spraying, which was done twice, with various H2O2 concentrations (1, 3, 6, 12, and 18%) on the potato photosynthetic apparatus efficiency and antioxidant capacity. The measurements were taken four times: on the first and seventh day after each application. Foliar spraying with 1% H2O2 concentration was the most stimulating for the course of physiological processes in leaves. Further increased doses of H2O2 enhanced stress in plants which is manifested by a decrease in pigment levels, photosynthetic attributes, antioxidant capacity in leaves, and fresh mass above-ground parts of potato plants. The intensive effect of spraying was particularly observed on the first day after application, while later, the activity of the photosynthetic apparatus and antioxidant capacity increased. The study provides information that foliar spraying with 1% H2O2 can be taken into account in further research on the development of a potato plant protection methods.

“…Destaca su uso como agentes blanqueantes, desinfectantes y oxidantes de materia orgánica, así como los productos que se generan como consecuencia de su empleo. Son de muy sencillo tratamiento desde el punto de vista medioambiental; sin embargo, los métodos de síntesis, son poco eficaces, por lo que se ha buscado la implementación de nuevas tecnologías como es el caso de los métodos electroquímicos (Schmalz et al, 2009;Cañizares et al, 2009;Raffellini et al, 2011;Velazquez-Peña et al, 2013;Saha et al, 2004). Los métodos electroquímicos se caracterizan por poseer una amplia compatibilidad ambiental, sencilla operación, alta eficiencia y bajo costo respecto a otras tecnologías y procesos convencionales en la producción de oxidantes, pues el principal precursor empleado es el electrón, considerado como un reactivo limpio, ya que evita el uso de otros compuestos químicos que por sí mismos pueden ser tóxicos o peligrosos (Panizza y Cerisola, 2005).…”
