“…Herbicides constitute more than half of all pesticides used in the developed world (Hua et al 2006a). A number of studies have reported the occurrence of pesticides and herbicides and their metabolites in surface water, groundwater and near-surface aquifers in the United States (Thurman et al 1992;Kolpin et al 1996Kolpin et al , 1998aKolpin et al ,b, 2000Kolpin et al , 2002Boxall et al 2004).…”

Endocrine disrupting compounds (EDCs) and pharmaceuticals and personal care products (PPCPs) are a group of chemical compounds with diverse physical and chemical properties. Recent studies have indicated undesired effects of EDCs and PPCPs at their reported trace concentrations (ng l 21 to mg l 21 ). This paper reviews the current knowledge on the sources, properties, occurrence and health impacts of EDCs and PPCPs, and their removal from drinking water using ozonation and ozone/hydrogen peroxide-based advanced oxidation. The paper also examines the potential threats posed by these chemicals to drinking water and public health.While these compounds are known to have adverse effects on ecosystem health, notably in the fish population, a similar link is yet to be established between ingestion of these compounds through drinking water and human health. In addition, data on the effectiveness of existing methods for the removal of these compounds are not conclusive. Further studies are required to characterize risks, and also to evaluate and optimize existing removal processes. Also concerted international effort is urgent to cut down the risk of exposure and restrain the production and marketing of toxic chemicals.

“…To solve such a problem, biological degradation was very effective for the treatment of many organic compounds but it was not entirely efficient if non biodeg r a d a bl e c om po und s we r e p r e s e nt i n t he wastewaters. In that case, other techniques like Fenton reaction, ozonation, photocatalysis, sonication, irradiation or their combinations were used [8][9][10][11][12][13].…”

In this work, a ruthenium dioxide electrode has been prepared by thermal decomposition at 400 o C then used for the oxidation of commercial amoxicillin. The physical characterization showed that RuO 2 electrode presents a mud cracked structure. Its electrochemical characterization has revealed an increase of the voltammetric charge in acid electrolyte compared to neutral electrolyte indicating the importance of protons in its surface redox processes. The voltammetric study of the oxidation of amoxicillin has been investigated. It has been obtained that the oxidation of amoxicillin is controlled by both adsorption and diffusion processes. Moreover, the oxidation of amoxicillin occurs via direct and indirect processes in free or electrolyte containing chlorides. Through preparative electrolysis, enhancement of amoxicillin oxidation was observed in the presence of chloride where the amoxicillin degradation yield reached more than 50 % compared to less than 5 % in the absence of chlorides. Spectrophotometric investigations have revealed the degradation of intermediates absorbing at 350 nm.

“…Ozone is used widely in water treatment technology because of its powerful oxidation [28][29][30]. However, it has been reported, in most cases, the ozonation cannot completely degrade organic compounds and sometimes produce toxic intermediates.…”
