“…Emerging organic contaminants are compounds yet to be recognized for the contaminant legislation, meaning that the incidence, risk, and ecotoxicological dates are not available, and it is difficult to know their potential harm in humans, animals and plants (Hurtado et al, 2016;Carraro et al, 2018). Emerging organic contaminants do not need to stay long time in the environment to produce negative effects because they are constantly introduced into water bodies (mainly in wastewater), and their concentration is increased little by little, for this reason it is necessary to focus on their degradation or transformation to none contaminant molecules (Naidu et al, 2016).…”

Toxic contaminates have profound consequences on both health and the environment. Consequently, effective approaches for addressing the effects of these toxicants are paramount. Here, we review recent progress in developing polymeric sequestrants for biological toxins, heavy metals and organic micropollutants. Polymers have several advantages as sequestration materials, including relatively low cost and high affinity for target compounds. As a result a number of polymer-based toxin-mitigation applications have been investigated. Naturally occurring toxins may be neutralized with polymers capable of binding and eliminating them from the body. Heavy metal contamination from mining operations, energy and industrial sources may also be mitigated with appropriate chelating polymers, both for environmental remediation and in chelation therapy for metal poisoning. Micropollutants such as pesticides from agriculture and polycyclic aromatic hydrocarbons from combustion processes may also be isolated using polymeric materials. Each of these applications illustrates the capabilities of polymers for eliminating toxic contaminants, thereby facilitating greater health and sustainability.

Thiabendazole degradation (TBZD) in diferent types of water matrices was assessed by applying two Advanced Oxidation Processes, both using simulated solar light (SSL), copper slag (CS) as an iron based catalyst, and separately H2O2 or NaOCl as oxidants. First, optimum conditions for TBZD were evaluated in distilled water, TBZD = 90% at 60 min for CS-H2O2-SSL, while 92% of TBZD in a twelfth of the time by the system CS-NaOCl-SSL; minimum TBZ-depletion variations, were observed between the first and the fifth reuse test: 88 ± 2% for CS-H2O2-SSL (60 min) and 90 ± 1% for CS-NaOCl-SSL (5 min). Those conditions were tested using a synthetic (SE) and a real secondary effluent (RE) from a WWTP. The CS-H2O2-SSL system achieved TBZD of 88 and 77%, after 90 min for SE and RE, with kinetic constants of 0.024 and 0.016 min−1, respectively. Whereas, photo-NaOCl/Fe showed values of 0.365 and 0.385 min−1 for SE and RE, achieving a 94% TBZD removal in both types of water at 10 min. That might be related to the formation of Cl· and HO• during the photo-NaOCl/Fe process, highlighting that the CS-NaOCl-SSL is an attractive option that has great possibilities to be scaling up by a better knowledge in real aqueous matrices.
