dc.description.abstract | Pet cats and dogs have been successfully used as indicators of environmental pollution by a great variety of chemicals, including metals. However, information on mercury (a well know priority environmental pollutant) concentrations in household pets tissues and/or organs is scarce. Thus, in the present work we quantified total mercury (Hg(Total)) in blood and hair samples from twenty-six household dogs. The obtained results disclose relatively low levels of total mercury in the surveyed dogs, with values ranging from 0.16 to 12.38 ng g(-1) in blood; and from 24.16 to 826.30 ng g(-1) in hair. Mercury concentrations were independent of gender, age and diet type. A highly significant positive correlation was established between total mercury in blood and hair, validating the latter as a surrogate, non-invasive matrix for mercury exposure evaluation. Additionally, the obtained blood to hair ratio (200) is similar to the one described for humans reinforcing the suitability of dogs as sentinels. Overall, the determination of total mercury levels in dogs' hair samples proved to be a good screening method for the estimation of mercury burden in this species. We propose the quantification of Hg(Total) in hair as a screening method for sentinels like household pets to be performed in routine veterinary visits. | pt_PT |
dc.description.sponsorship | To Zeca and Dona Maria Pia, the pets that inspired this study. The authors would like to thank all the dog owners who authorized the collection of blood and hair samples from their pets. The staff of the veterinary clinics involved in this project is also acknowledged, particularly their Medical Directors: Sónia Miranda, DVM and Joana Tuna, DVM. This study was supported by the Portuguese Foundation for Science and Technology (FCT) trough program COMPETE and the projects PEst-C/MAR/LA0017/2011 and PEst-C/SAU/UI0709/2011. A.C.A.
