Abstract

The aim of the present work is to provide a picture of the current knowledge on Animal Biomonitoring Systems and highlight the link between environmental pollution and Public Health concerns. In this paper are showed the results of three studies performed during the PhD scholarship focused on environmental monitoring using domestic animals as sentinel animal systems. Environmental biomonitoring through domestic animals appears to be more feasible and effective compared to other research models, because animals share with humans the same risks of exposure to pollutants; the growing need of an early detection of industrial pollutants in the environment, especially micropollutants which have adverse effects at very low concentrations, is at the basis of Public and Environment Health surveillance programs. Furthermore, it’s important to disclose the presence of these compounds directly or through certain molecular biomarkers in living organisms rather than in the natural environment, where they are often present below the detection threshold. Here we report the preliminary data of a project developed in Basilicata region (Southern Italy): Project S.E.BIO.VET. (Environmental Epidemiology Study and VETerinary BIOmonitoring in Basilicata) using sheep as animal sentinel to verify the impact of gas drilling on the environment. Furthermore we investigated the utility of necropsy on pets to evaluate environmental pollution by heavy metals, through a research project performed on the entire Campania Region, leaded by the Regional Referal Center of Veterinary Urban Hygene (CRIUV). Laslty, we provide new insights for the use of dairy cattle as early warning for environmental pollution by nitrate and nitrite, highlighting new aspects of nitrate toxicosis which may occur both in animals and humans. Results of this work confirmed that dog is a good sentinel animal system in urban and rural areas, and can be used for epidemiological and comparative pathology studies for tumors in humans. Dairy cattle are one of the most sensible specie to nitrate and nitrite toxicosis, compounds which can be released even in milk which can be a dangerous source of exposure for humans. In this study, the preliminary data of SEBIOVET project confirm the crucial role of small ruminants to monitor environmental pollution on large scale, to have indications on the presence of unknown polluted site, or to monitor already known contaminated areas.
