DETECTION OF HEAVY METALS FROM MOLLUSCS SHELLS

This work presents aspects regarding some heavy metals (Cd, Pb, Cu and Zn) concentration in shells of different molluscs (Mytilus galloprovincialis, Rapana thomasiana, Mya arenaria, Scapharca) collected from the Romanian Black Sea Coast. The heavy metals were analysed using atomic absorption spectrometry

INVESTIGATION OF HEAVY METALS FROM SOME ALIMENTARY PRODUCTS

The presence in high amount of organic pollutants and heavy metals in environmentrepresents a potential danger for human health and for environment too. This workpresents aspects regarding the pollution with heavy metals (Cd, Pb, Cu and Zn) of some food products: caw milk, caw cheese and caw meat. The samples analysed were collected from some housekeeping of Lumina (Constanta). The heavy metals were analysed using atomic absorption spectrometry

Quality Control of Different Types of Honey and Propolis Collected from Romanian Accredited Beekeepers and Consumer’s Risk Assessment

Honey is a natural product recognized and appreciated for its nutritional value and therapeutic potential. However, the quality of bee honey is essential because various contaminants can seriously affect consumers’ health. In the experimental part of the work, we analyzed different types of honey (linden, black locust, rapeseed and multifloral honey) and propolis, which were collected from Romanian accredited beekeepers who placed beehives in two areas characterized by different industrial activity: area 1 (A1) is an area with intense industrial activity, with other industries existing nearby, including a refinery, while area 2 (A2) is entirely devoid of industrial activity, but with moderate agricultural activity. A total of 144 samples were collected, twelve samples for each variety of honey, propolis and soil, corresponding to each area analyzed. In addition, seven heavy metals and three pesticides were tested for in the samples collected. Finally, the correlation between the degree of contamination with soil pollutants and the contamination of the bee products harvested from the analyzed areas was studied. Cadmium, lead, copper, zinc and the sum of DDT metabolites exceeded the maximum allowable levels in honey samples, with differences between different types of honey
