Maternal environmental tobacco smoke (ETS) exposure during pregnancy may threat the health of mothers and their newborns. The present study was performed to determine the potentially toxic metals (PTMs) in umbilical cord blood as a biomarker for passive smoker women, as well as their association with neonatal birth indicators. In total 128 mothers (exposed: 64 and non-exposed: 64) were selected as participants. A volume of 2 mL umbilical cord blood was sampled from each participant, and PTMs including As, Pb, Cr, Al, Co, Cd, Zn, Cu, Mn, Fe, Se and Ni levels were analyzed by ICP-MS. The mean concentration levels of all PTMs in exposed group was higher than non-exposed (As: 1.76, Al: 1.49, Pb: 2.57, Cd: 1.04, Cr: 1.15, Co: 1.10, Zn: 1.05, Cu: 3.41, Mn: 1.56, Fe: 1.22, Se: 1.69 and Ni: 1.03 times fold). There were statistically significant differences between the mean levels of all PTMs (except Ni and Zn) in exposed and non-exposed groups (p-value˂0.05). In exposed group, the mean of weight, height, head circumference and chest circumference of newborns were 3058.12 ± 139.23 g, 48.50 ± 0.97 cm, 34.82 ± 0.61 cm and 32.65 ± 0.20, respectively. These values in non-exposed group were 3270.48 ± 192.49 g, 50.47 ± 0.95 cm, 34.91 ± 0.60 cm and 33.14 ± 0.38 cm, respectively. Newborns of ETS exposed mothers had significantly lower weight, height, Apgar 1 min, and chest circumference at birth. With regards to the results of the present study, more comprehensive studies should be conducted in future to identify the markers of long-term exposure to tobacco smoke and tracking the biomarkers of tobacco smoke exposure in other biological matrices such as newborns blood, meconium, feces and urine.
L'esposizione materna al fumo di tabacco ambientale (ETS) durante la gravidanza può minacciare la salute delle madri e dei loro neonati. Il presente studio è stato condotto per determinare i metalli potenzialmente tossici (PTM) nel sangue del cordone ombelicale come biomarcatore per le donne fumatrici passive, nonché la loro associazione con gli indicatori di nascita neonatale. In totale, 128 madri (esposte: 64 e non esposte:64) sono state selezionate come partecipanti. Un volume di 2 mL di sangue del cordone ombelicale è stato campionato da ciascuna partecipante e i livelli di PTM, tra cui As, Pb, Cr, Al, Co, Cd, Zn, Cu, Mn, Fe, Se e Ni, sono stati analizzati mediante ICP-MS. I livelli di concentrazione medi di tutti i PTM nel gruppo esposto erano superiori a quelli dei non esposti (As: 1,76, Al: 1,49, Pb: 2,57, Cd: 1,04, Cr: 1,15, Co: 1,10, Zn: 1,05, Cu: 3,41, Mn: 1,56, Fe: 1,22, Se: 1,69 e Ni: 1,03 volte). Sono state riscontrate differenze statisticamente significative tra i livelli medi di tutti i PTM (eccetto Ni e Zn) nei gruppi esposti e non esposti (valore p = 0,05). Nel gruppo esposto, la media di peso, altezza, circonferenza cranica e circonferenza toracica dei neonati era rispettivamente di 3058,12 ± 139,23 g, 48,50 ± 0,97 cm, 34,82 ± 0,61 cm e 32,65 ± 0,20. Questi valori nel gruppo non esposto erano rispettivamente di 3270,48 ± 192,49 g, 50,47 ± 0,95 cm, 34,91 ± 0,60 cm e 33,14 ± 0,38 cm. I neonati di madri esposte al fumo passivo presentavano peso, altezza, indice di Apgar a 1 minuto e circonferenza toracica significativamente inferiori alla nascita. Per quanto riguarda i risultati del presente studio, in futuro dovrebbero essere condotti studi più approfonditi per identificare i marcatori dell'esposizione a lungo termine al fumo di tabacco e monitorare i biomarcatori dell'esposizione al fumo di tabacco in altre matrici biologiche come il sangue, il meconio, le feci e l'urina dei neonati.

Abstract
Maternal environmental tobacco smoke (ETS) exposure during pregnancy may threat the health of mothers and their newborns. The present study was performed to determine the potentially toxic metals (PTMs) in umbilical cord blood as a biomarker for passive smoker women, as well as their association with neonatal birth indicators. In total 128 mothers (exposed: 64 and non-exposed: 64) were selected as participants. A volume of 2 mL umbilical cord blood was sampled from each participant, and PTMs including As, Pb, Cr, Al, Co, Cd, Zn, Cu, Mn, Fe, Se and Ni levels were analyzed by ICP-MS. The mean concentration levels of all PTMs in exposed group was higher than non-exposed (As: 1.76, Al: 1.49, Pb: 2.57, Cd: 1.04, Cr: 1.15, Co: 1.10, Zn: 1.05, Cu: 3.41, Mn: 1.56, Fe: 1.22, Se: 1.69 and Ni: 1.03 times fold). There were statistically significant differences between the mean levels of all PTMs (except Ni and Zn) in exposed and non-exposed groups (p-value˂0.05). In exposed group, the mean of weight, height, head circumference and chest circumference of newborns were 3058.12 ± 139.23 g, 48.50 ± 0.97 cm, 34.82 ± 0.61 cm and 32.65 ± 0.20, respectively. These values in non-exposed group were 3270.48 ± 192.49 g, 50.47 ± 0.95 cm, 34.91 ± 0.60 cm and 33.14 ± 0.38 cm, respectively. Newborns of ETS exposed mothers had significantly lower weight, height, Apgar 1 min, and chest circumference at birth.
