The last type is atmospheric pollution‚ also referred to as air pollution and is defined as gasses or solid particles such as soil which are found in the air and can settle in bodies of water. The contanimants described above come from a number of sources including storm sewers‚ spills‚ landfills and can enter Lake Huron via variety of methods including atmospheric deposition

BIOREMEDIATION INTRODUCTION:- The process of bioremediation was reportedly devised by George M Robinson in the 1960 during experimentation with dirty jars and the introduction of microbes this was however not applied until the 1972 clean out of the fuel holding tanks on the RMS queen mary. Science 1972 bioremediation has become greater developed as a means of cleaning up spills of gasoline diesel ‚ heavy metals and other easily degraded petroleum products (National Research Council 1993).

-Bioremediation is the use of micro-organism metabolism to remove pollutants. Technologies can be generally classified as in situ or ex situ. In situ bioremediation involves treating the contaminated material at the site‚ while ex situ involves the removal of the contaminated material to be treated elsewhere. Bioremediation can occur on its own (natural attenuation or intrinsic bioremediation) or can be spurred on via the addition of fertilizers to increase the bioavailability within the medium (biostimulation)

Heavy metal contamination occurs though all facets of life such as air‚ water‚ food‚ soil‚ and in everyday objects and occurrences. When heavy metals enter the air from factories emissions and smoke‚ it is exposed to the body‚ which mostly affect your skin and lungs such as Cadmium and Arsenic. Common water contaminates are Chromium and Thallium‚ Chromium can enter the water source usually through spills and leaks from power plants. Thallium like other metals occurs naturally in water but some areas

that I have found in my state was the Chemtronic‚ Inc. in Swannanoa‚ NC. It is about 1‚027 acres and only about 20 acres in total are contaminated with these pollutants. This property has had several owners and operators and it was first developed as an industrial site in 1952. After first opening the first products that were manufactured on this site were explosives‚ incapacitating agents‚ and chemical intermediates. There are about 23 individual on-site disposal areas that were identified during
