Degradation of organophosphoric esters in leachate from a sea-based solid waste disposal site

Distribution of organophosphorus flame retardants in sediments from the Pearl River Delta in South China

“…In addition to the usage of PFRs in the study area, other factors could also affect the vertical distribution of non-halogen PFRs in the sediment core. Most of the non-halogen PFRs that are not considered as persistent, such as rapid photodegradation for TBEP and biodegradation for TPhP and TCrP (van der Veen and de Boer, 2012;Regnery and Püttmann, 2010), while the halogen PFRs are difficult to degrade (Kawagoshi et al, 2002). Taking this factor into consideration, a more accurate vertical distribution of non-halogen PFRs could not be presented readily.…”

Degradation of tri(2-chloroethyl)phosphate by a microwave enhanced heterogeneous Fenton process using iron oxide containing waste

“…The chlorinated OPEs, such as tri(2-chloroethyl)phosphate (TCEP), tri(2-chloroisopropyl)phosphate (TCPP) and tri(dichloropropyl)phosphate (TDCP), have been reported to be carcinogenic 9 and neurotoxic. They are considered to be persistent pollutants [10][11][12] and have been shown to resist biodegradation, chlorination and ozonation in treated waters. 13 Owing to their widespread, toxicity and persistence, removal of the chlorinated OPEs in the contaminated environment is necessary and signicant.…”

Occurrence and distribution of organophosphate triesters and diesters in sludge from sewage treatment plants of Beijing, China

“…TCEP and tris(1,3-dichloro-2-propyl) phosphate (TDCP) have been proven to be carcinogenic (Brandsma et al, 2014;Wang et al, 2015), while tri(2-chloroisopropyl) phosphate (TCPP) and tributoxyethyl phosphate (TBEP) are also suspected as carcinogens (Brandsma et al, 2014;Venier et al, 2014;Wang et al, 2015). Additionally, chlorinated alkyl phosphates are considered as persistent pollutants due to their resistance to degradation (Kawagoshi et al, 2002;Meyer and Bester, 2004;Bollmann et al, 2012;Gao et al, 2013).…”
