Photocatalytic Pathway toward Degradation of Environmental Pharmaceutical Pollutants: Structure, Kinetics and Mechanism Approach

Abstract

During the last few years, the presence of pharmaceuticals in the aquatic environment, classified as the so-called emerging contaminants, evoked an issue among the scientific community. From the uptake mechanism of the pharmacology route administration of pharmaceuticals, it will be expelled as a mixture of metabolites, as neutral substance, or conjugated with an inactivating compound attached to the molecule. After usage, the expelled by-products are usually only partially metabolized and end up in the wastewater treatment. A large amount of these substances is not destroyed by traditional sewage and wastewater treatment plants, thus eventually released into receiving waters. Their environmental existence gains attention world widely owing to their related abnormal physiological processes in reproduction, spurt incidences of cancer, enhancing of antibiotic persistence bacteria and potential increment of hazardous chemical mixtures. Pharmaceutical pollution in the environment exists as an immense issue for human as well as the environment. These type of pollutants have been discovered in areas of such low human population, such as the Antarctic. Although their influence - on both human health and the environment is, barely discernable, however, behavioral effects and physiological have already been detected in a number of species. There is a significant verification of the unfavorable impacts on human health such as endocrine disruptors present at low concentration in the environment. Environment pollution by pharmaceuticals waste needs to be known through the quality use of medicines and quality sewage treatment. Through appropriate use of pharmaceuticals and suitable sewage system, the environmental impact of pharmaceuticals may be reduced without affecting the health welfare gained through the intake of these medicines. Therefore, the photocatalytic degradation of pharmaceutical pollution as a suitable method should be reviewed and focused.
