Paraben Compounds—Part II: An Overview of Advanced Oxidation Processes for Their Degradation

Water scarcity represents a problem for billions of people and is expected to get worse in the future. To guarantee people’s water needs, use “first-hand water” or reuse wastewater must be done. Wastewater treatment are favorable this purpose, since first-hand scarce economic needs exploration type increasing. In treatment, it important remove contaminants emerging concern, as well pathogenic agents. Parabens used daily products preservatives detected different sources. These compounds related human health problems due their endocrine-disrupting behavior, several animals. Thus, removal from streams essential achieve safe reusable water. Advanced Oxidation Processes (AOPs) considered very promising technologies can alternatives complements conventional treatments that inefficient such contaminants. Different AOP ozonation, catalytic photocatalytic Fenton’s, photocatalysis, among others, have already been parabens abatement. This manuscript critically overviews were evaluated terms ecotoxicological assessment resulting by-products abatement more toxic than parent compounds. The aspect was also analyzed evaluate compare technologies.
