Abstract

Background Polycyclic aromatic hydrocarbons (PAHs), some ubiquitous environmental contaminants are capable to cause oxidative stress, during its metabolism. It is believed that many diseases that have a common origin in oxidative stress begin in childhood. Considering oxidative stress evolved during PAHs metabolism as one main mechanism responsible for health hazards related to PAHs exposure in children, we biomonitored blood PAHs levels in connection with redox status among children of Lucknow (India).Methods The study consisted of children (n = 50) who visited to the Pediatrics Department (KGMU) Lucknow for usual health check-up camp over the study period (August 2005-July 2006). Blood samples were drawn and levels of acenaphthylene, anthracene, phenanthrene, fluoranthene, naphthalene, pyrene, benzo(b)fluoranthene, benzo(k)fluoranthene and benzo(a)pyrene were determined by HPLC-FD/UV. Malondialdehyde (MDA), glutathione (GSH) levels, catalase (CAT) and superoxide dismutase (SOD) activity were also determined to evaluate redox status.Results Significantly elevated carcinogenic blood PAHs levels (125.55 +/- 26.99ppb, p < 0.05) were found in rural children compared to children from urban region (23.96 +/- 13.46). Results revealed that remoteness between residence and highway/traffic, significantly influences the blood levels of carcinogenic PAHs. There were significant correlations between total PAHs and MDA (r = 0.82, p < 0.001), carcinogenic PAHs and SOD activity (r = 0.35, p < 0.01), Total PAHs and blood GSH level (r = - 0.49, p < 0.01) and carcinogenic PAHs and CAT activity (r = 0.42, p < 0.01). Blood MDA level was also found correlated with increasing body mass index (BMI) (r = 0.29, p < 0.05).Conclusion Our results showed blood PAHs levels in children significantly correlated with oxidative stress and altered antioxidant status. It supports our hypothesis that the children exposed to high PAHs level will suffer more to oxidative stress that may lead to possible health risks. Additional studies with large sample size are considered necessary to strengthen the database and also to explore the PAHs associated health risks in children.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
