تقدير بعض العناصر الثقيلة في عسل النحل شرق/غرب/جنوب ليبيا وتحديد جودته كمؤشر على تلوث البيئة

Abstract

In this study, four samples of honey were collected from three different regions in Libya, including Benghazi, Gharyan, and Sebha, as well as a test sample. These samples were subjected to tests in order to ensure their quality, and they did not contain a high percentage of heavy metals. The pH values, estimation of moisture content, ash content estimation, and electrical conductivity estimation are carried out. The results obtained showed that there were differences between all samples. The pH values for all samples ranged from 4.13 - 5.32, the moisture content from 10.47 - 15.11%, the ash content from 0.5- 1.6%, and the electrical conductivity from 0.14 - 0.73 mS/cm.Furthermore, the funding showed that the cadmium concentration in honey samples ranged from 0.08 to 0.0293 ppm. By comparing these results with the internationally permissible rates, it was revealed that all samples were within the permissible rates with the exception of sample A3 (the sample collected from Benghazi). This difference is due to the differences in the environment surrounding each sample, such as the plant source, geographical location, topography, and climate of each region. As well as the difference in the chemical composition of honey from one, sample to another and according to the type of food used. While the rest of the heavy elements in all study samples were within the permissible international rates.
