Database of persistent organic pollutants in umbilical cord blood: Concentration of organochlorine pesticides, PCBs, BDEs and polycyclic aromatic hydrocarbons.

Persistent organic pollutants (POPs) have been banned over the last decades for being damaged to the environment and to the health of humans and animals. However, due to their lipophilic nature and resistance to degradation, they are frequently detected in biological samples. Its presence has been associated with the increased risk of suffering from different diseases in human series, being newborns and children especially sensitive. The present data reports umbilical cord blood levels of twenty organochlorine pesticides (aldrin, dieldrin, endrin, o,p'-DDD, p,p'-DDD, o,p'-DDE, p,p'-DDE, o,p'-DDT, p,p'-DDT, endosulfan alfa, endosulfan beta, endosulfan sulphate, heptachlor, HCB, αHCH, βHCH, δHCH, lindane, methoxychlor and mirex), eighteen polychlorinated biphenyls (congeners 28, 52, 77, 81, 101, 105, 114, 118, 123, 126, 138, 153, 156, 157, 167, 169, 180 and 189), eight bromodiphenyl ethers (congeners 28, 47, 85, 99, 100, 153, 154 and 183), and sixteen polycyclic aromatic hydrocarbons (acenaphthalene, acenaphthene, anthracene, benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, benzo(g,h,i)perylene, benzo(k)fluoranthene, chrysene, dibenzo(a,h)anthracene, fluoranthene, fluorine, indene(1,2,3-cd)pyrene, naphthalene, phenanthrene and pyrene). A total of 447 samples, representing 86.6% of the total births during the recruited period (March 1, 2015, to April 30, 2016), were available for POP analyses. POPs were determined in a Gas Chromatography (GC) system equipped with an automated sampler (Models 7890B and 7693; Agilent Technologies, Palo Alto, CA, USA) for gas chromatographic separations. The detection of the analytes was performed using a Triple Quad 7010 mass spectrometer (Agilent Technologies). All of the measurements were performed as triplicate measurements, and the means were used for the calculations. Data are reported in ng/mL. The present data also includes birth parameters, including weight, length, cranial perimeter, Apgar score and congenital malformations, and data referred to mothers (harmful habits, chronic diseases, and anthropometric/demographic characteristics).

Experimental design, materials, and methods

All samples were recruited in the island of La Palma (Canary Islands, Spain). The present series represents the 86.6% of the total births during the recruited period (March 1, 2015, to April 30, 2016). Birth parameters were recorded at the delivery room, as previously reported [1]. Data referred to mothers were recorded and included anonymously in the database. Both parents were required to sign an informed consent. This study was approved by the Ethics Committees of the Hospital of La Palma and the University of Las Palmas de Gran Canaria in accordance with the Declaration of Helsinki. The samples were stored according to the regulations dictated by the Spanish Law of Biomedical Investigation of 2007 (Law 14/2007) and the data were saved according to the Data Protection Act (Ley Orgánica 15/1999).

Sample preparation, instrumentation, and quality assurance/quality control are extensively exposed in a previous publication [2,3]. We used PASW Statistics version 19.0 (SPSS Inc., Chicago, IL, USA) to manage the database and perform statistics [2].

Value of the Data• The present data is useful because reports levels of 62 POPs in a series of 447 umbilical cord blood samples, together with the demographic and clinical parameters recorded for the series. The present data help interpreting effects caused by the inadvertent exposure to these hazardous compounds. • These data will benefit everyone conducting biomonitoring studies in human populations, especially those who conduct meta-analysis. • Data provided can be reanalysed, compared to other datasets in other series, and used for meta-analyses. • Although many studies have been published reporting levels of POPs in human populations, few include such amount of substances in a population as sensitive as newborns. • The present series includes 87% of the births registered in La Palma Island (Canary Islands, Spain) during 2016, which allows having a biomonitorization that includes almost all of a population segment in a specific period of time.
