MICA AREA AND HEAVY METALS POLLUTION ABSTRACT The reason for chosing to study Copsa Mica area is because this area is very close to my home town Medias‚ and Copsa Mica‚ alongside Baia Mare and Zlatna are known as the representative areas for nonferrous metallurgy in Romania. As a result of this almost 70 years old industrial activity‚ the Copsa Mica area is strongly polluted with heavy metals like: Cd‚ Pb‚ and Zn. The present paper presents some aspects impact of metals on environment and human

alkali and alkaline earth metal ion 2. Define ground state and excited state of an atom. Ground state- normal configuration of the electrons about the atom or the ion of an element; stable particle electrons are at lowest possible energy level Excited state- when stable particles are heated to very high temperatures some of the electrons leave their ground state and become “excited”; these electrons move to higher energy levels 3.

CHAPTER 5 DISCUSSION 5.1 Analysis of Trace Metal by FAAS Based on the table (4.3 and 4.4) the trace elements was detected by using the flame atomic absorption spectrophotometry analysis. The trace metal can be detected by the FAAS within 15 seconds to 30 seconds of each soil sample. Before the samples were analysis with the FAAS‚ the blank samples were run in the machine for each element that was being analyzed. Their absorbances were read. The mean of each blank was calculated and

experiment aimed to determine the specific heat of two different metals‚ Lead and Zinc‚ in order to calculate their individual atomic weight. Theory The calorimeter consists of a metal outer cup‚ a removable metal inner cup‚ which is held in place by a rubber ring‚ and an insulating lid with a small opening for a thermometer. It is a closed system as the air between the inner cup and outer cup insulates the water and heated metal‚ so‚ ideally‚ all heat is contained within the calorimeter (1). Early
