RESEARCHES CONCERNING THE HEAVY METAL CONTENT OF THE RAPE HONEY ORIGINATING FROM THE BANAT AREA IN THE YEARS 2006-2007

Abstract

The purpose of the researches was the observation of the heavy metal quantity existing in four rape honey samples, originating from Bulgarus and Grabat localities from 2006- 2007 production.. In 2006 besides the other elements observed in 2007, has been noticed the nickel that varied between 0.02 mg/kg in Bulgarus and 0.002 mg/kg in Grabat. From the data, it is observed that in the 2007 collected honey, besides the existing metals from 2006 has been identified the zinc that in Grabat has had a very high concentration of 0.07 mg/kg and in Bulgarus its concentration was 0.03 mg/kg and the ferrum with the following values : 0.03 mg/kg in Bulgarus and 0.005 mg/kg in Grabat. In all four collected samples the chromium has had the same concentration of 0.001 mg/kg in both years of experiments. The paper is original through the research and honey samples’ collection manner, the location and the years of research and also due to the fact that the researches were developed in two neighboring localities that during the year don’t get the same precipitation quantities according to the climatic data existing in the town hall registers.
