Abstract
The dataset presented in this article supports “Selected persistent organic pollutants associated with the risk of primary ovarian insufficiency in women” (Pan et al., 2019). The supplementary data were as follows: (1) Detailed information regarding pretreatment methods, instrumental analysis and methods validation of quantification of serum concentrations of persistent organic pollutants (POPs). (2) The total dioxin equivalents (TEQs) levels of dioxin-like PCBs (DL-PCBs) in primary ovarian insufficiency (POI) cases and controls, as well as the association of TEQ levels with the risk of POI. (3) The results of principal components analyses (PCA) about 20 POPs that were detected in >40% samples.
Highlights
Supporting dataset and methods for serum concentrations of selected persistent organic pollutants measured in women with primary ovarian insufficiency
The dataset presented in this article supports “Selected persistent organic pollutants associated with the risk of primary ovarian insufficiency in women” (Pan et al, 2019)
The within- and between-run precision was lower than 20%, and for and high spikes, the precision was lower than 15% among three days for all target compounds
Summary
How data was acquired Gas chromatography-triple quadrupole mass spectrometer (GC-MS/MS) (Agilent 7890B GC/7000C). Spiked 0.3 mL of serum sample in a centrifuge tube with internal standards [PCB 209, tetrachloro-mxylene (TCMX), isotopically labeled standards of PBDEs]. After three times of liquid-liquid extraction by extractant of n-hexane and dichloromethane (DCM) (1:1, v/v), evaporating the extracts to about 1. ML, and cleaned by a column filled with activated silica gel and Na2SO4. The elution was evaporated to dryness and redissolved in 50 mL of n-decane. Recruited 157 primary ovarian insufficiency (POI) cases and 217 healthy controls. Serum concentrations of polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs), polybrominated diphenyl ethers (PBDEs) were measured
