The Level of Some Heavy Metals Accumulation in Animals Reared in Central Area of Romania

In the influence area of an industrial platform there were harvested organs samples, blood samples and bone samples from cattle and horses, already dead or slaughtered in necessity in three localities: Axente-Sever, Copsa Mica and Seica Mica. Determination of lead and cadmium from harvested samples was made by atomic absorption spectrometry, estimating the absorption of radiation at strength wave of 228.8 nm for cadmium and at strength wave of 283.3 nm for lead. The analysis of the obtained results was made in compliance with the stipulated standards. The researches led to the following conclusions: - regular values for lead and cadmium in blood samples are exceeded by 2 times for lead and by 5 to 13 times for all samples and sampling points; - lead admitted concentration is exceeded in all cattle organs samples; the exceeding was about 1.34 to 45.7 times - the highest concentration being noticed in kidney, liver, spleen and heart; - cadmium admitted concentration was exceeded by 2 to 20 times for all samples and sampling points; - in horse organ samples, lead concentration was exceeded by 2 to 41 times and the cadmium concentration by 2 to 192 times; - for bone samples lead concentrations reveal an exceeding by 3 times and the cadmium by 5 to 10 times; - the high concentrations of lead and cadmium which are detected in the analyzed samples (organs, blood and bone samples) proves a massive pollution for this area and also indicates chronic toxicosis of animals.

THE EVALUATION OF RISC IN THE COMERCE WITH ANIMALS AND ANIMAL PRODUCTS

The evaluation of risc is preferable if not necessary, after the World Trade Organisation (WTO) was formed, this reffers to meintaining a “level 0 of risc”, because this leads to a more objective decision and it permits the vetrinary authorities to debate on what could occure in certain situations, regarding the potential riscs.(2) In this content The World Organisation for Animal Safety (OIE), has fixed in The Terrestrial Code certain levels of exigence which assure the lowest possible risc which can be accepted for each animal species, for each disease and differently for live animals and animal products.(1) Analising the risc for animal health is tightly corelated with Epidemiology and Statistics, but also with other scients such as those which are structured on the “theory of decisions” . In fact , risc analasis relies on the accumulated knowledge of these sciences in time, from which an important role has Epidemiology. In the last years taking decisions was based on rational analasis, and this has changed from analising only the surface, which relies only on stating laws, reglementations and rules, in a form which is more consistent and more powerfull, that takes notice and treats the different situations in different countries and takes care of the safety of animals and not of the politic considerations. We can conclude that this sciente is based on the theory of decissinos , the technology for international manegement and on the tarditional scinetes such as Epidemiology and Statistics. (3)
