The degree of toxic metals contamination in water, vegetables and respective soils in the studied area - KCM Smelter site - Plovdiv-Assenovgrad is evaluated in individual and integral aspects. The analytical measurements were performed by inductively coupled plasma atomic emission spectrometer (ICP-AES), Jobin Yvon ULTIMA 2. The analysis lines in the determination of impurities were selected in view of spectral interference. Ground, surface, waste - water and some corresponding soil samples were investigated for m...

In the connection with work on the International project NATO Science for Peace 973739 "Dynamics, evolution and limitation of heavy metal water pollution in the Plovdiv region (Bulgaria)" a complex ecological investigation was accomplished. The main parts of the work have been related to clarification of the hydrogeological peculiarities in order to assess conditions and risk of contamination of the ground waters. For this purposes in the period 2001-2003 a monitoring network for seasonal and monthly observations ...

This study is conducted through a NATO – Science for Peace Project “WATERMETAPOL”. Ground-water flow is a major premise for the dissemination of chemical pollutants after they have somehow fallen into the aquifer. The metallurgical plant is settled on a large alluvial cone of Chepelarska River. A highly productive aquifer is formed in the coarse grained deposits. The general direction of ground-water flow is northward, where a final discharge zones are Maritza River and Chepelarska River (lower reach). Sever...
