It is impossible to be thrown away by means of faces from
bodily construction of living organisms in the geographical
agriculture area. Biological accumulation occurs in their living muscle
tissues and grease. Heavy metal accumulation happens at the strapping living
creatures that use it up as nourishment. Heavy metals reach to a person by
going into his/her food chain. This study is carried out with an aim to being
determined of heavy metals’ concentration, which is dangerous for environmental
health.
The main important heavy metals are Sb, Ag, As, Be, Cd, Cr,
Pb, Mn, Hg, Ni, Se, Cu, Fe, Zn, Al. Being in a toxically character is the most
important feature of some of these heavy metals. Toxic metals: Ti, Hf, Zr, W,
Nb, Ta, Re, Ca, La, Os, Rh, Ir, Ru, Ba ; heavy toxic metals : Be, Co, Ni, Cu,
Zn, As, Se, Te, Pb, Ap, Cd, Pt, Au, Hp, Te, Pb, Sb, Bi.
Iron is mostly found in the nature. Iron can be change by
means of O2 and CO2 balance. Iron goes into liquid solution as being HCO3 when
two valuable irons come together with water and CO2. But it must be O2 for its’
being stable. In oxygenated environments, iron hydroxide (III), which cannot
dissolve in water, comes into being and falls down. In these happenings pH and
O2 are important. Nickel is being with Cu and Fe. Benefiting
areas of nickel are so wide (electronically things, money, car battery,
steel alloy, food, etc.). If it is evaluated for human body: if it is taken by
means of digestion, most of it is thrown away with feces. If it is taken by
means of respiration, throwing increases with urine. Most nickel salts are
costic and irritant. It causes death in 20 minutes when its concentration (Ni
Co)4 in the atmosphere exceeds 30 pp.
