The objective of this study was to evaluate the oxidation method to remove endocrine disrupting chemicals in reverse osmosis(RO) retentate for the reuse of wastewater effluent. Oxidation of organic pollutants was induced by the persulfate catalyzed by Fe(II). Affecting factors such as initial pH and ionic strength on the Fe(II) catalyzed persulfate oxidation were evaluated. 17α-ethynylestradiol (EE2) degradation efficiency decreased as pH and ionic strength increased. However, the efficiency increased as chloride ion concentration increased due to the influence of radical transfer.
We would like to introduce domestic subscribers of the Korean Journal of Blood Transfusion to the important aspects to be considered while selecting a reference allele and reporting a new allele candidate. ABO*A1.02 has only a single nucleotide substitution of c.467C>T in ABO*A1.01, and when ABO*A1.01 is used as the reference allele, the ABO*AW.10 allele should be marked as having both c.467C>T and c.784G>A variants. Unfortunately, it has not been modified as such in the ISBT database. For this reason, in the journal Transfusion (2020), the official journal of the Association for the Advancement of Blood Biotherapies, there was a report of a new allele with c.467C>T and c.784G>A variants. Cases of ABO*AW.10 allele with a weak A phenotype are not uncommon in Koreans, and it is necessary to accurately mark the reference allele. The blood type A reference allele of the International Society of Blood Transfusion (ISBT) database currently used for ABO alleles reporting is based on ABO*A1.01. Therefore, it should be considered that the ABO*AW.10 allele has both the c.467C>T and c.784G>A variants together.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
