Recent development in analysis of persistent organic pollutants under the Stockholm Convention

Dioxin and Related Compounds

“…In all seal tissues, PCDF concentrations were greater than PCDDs with total PCDD/F TEQ concentrations of 150, 164, and 89 pg/ g ww in blubber, liver, and muscle, respectively. These concentrations were higher than those found in previous studies of pinnipeds from the Antarctic [205,206] possibly due to local sources on Livingston Island which hosts three permanent scientific bases.…”

“…Methods for most halogenated compounds use common extraction and cleanup and techniques [204,205]. Polybrominated dioxins and furans [198,206,207] can be analyzed under similar conditions to those for chlorinated dioxins and furans, however shorter thin film columns should used and care must be taken to limit contamination from PBDEs and degradation from light and heat [207][208][209][210][211].…”

“…At the risk of oversimplifying matters, reproductive allotment strategies amongst species can be classified into two main groups: income and capital breeders. Income breeders do not deplete maternal lipid reserves during egg formation, but instead energy acquired while feeding at the breeding grounds is used as the primary energy source for egg development [205]. Capital breeders, conversely, use already-existing lipid stores that were acquired prior to the breeding season as an energy source for egg development [205].…”

Analytical methods for human biomonitoring of pesticides. A review

“…In this method, Roca et al [59] use acetonitrile as solvent, without a dispersive phase clean-up step , for the extraction of 29 metabolites of several pesticide classes. A modified QuEChERS-based procedure was also used by Luzardo et al [68] for the determination of 23 OC pesticides and other persistent compounds in human milk and colostrum using acetonitrile saturated with hexane for extraction and PSA in the clean-up step. The recoveries ranged from 76 to 105 %.…”

Effective remediation of phenol,2,4-bis(1,1-dimethylethyl) and bis(2-ethylhexyl) phthalate in farm effluent using Guar gum – A plant based biopolymer

“…Tang, 2013). According to Xu et al (2013), currently there are 22 POPs listed under Stockholm Convention.…”
