Component analysis of the different fish samples containing heavy metals in İstanbul Bosporus

Abstract

Fish and fish products are important sources in nutrition, especially for kids and youths. Turkey has the geographical advantage of being surrounded on three sides by the sea. However, the usage of seas unconsciously and fishing illegally cause pollution, which threatens human health, and decrease fish rates. In this study, distinguishable heavy metals are found (Pb, Cu, Ni, Al, Zn, etc.) that may affect human beings permanently in a negative way. The fish samples are analyzed, and significant heavy metal levels are displayed. The levels of heavy metals are introduced by using a mathematical approach and a statistical modeling. Original and new data are obtained from fishes related to levels of heavy metals. Data are analyzed by means of correlation-regression that is a linear model and a factor analysis method. Besides, regression equations and factor loadings are exhibited.
