Abstract

Fifteen crude oil samples were collected from different oil fields of the Kurdistan region, Northern Iraq to determine four trace metals, Fe, Ni, Cr and Pb. The analytical technique is applied mainly by flame atomic absorption spectrophotometry (ASS). Samples of these areas has not been previously examined for trace elements contents. API value of crude oils are inversely proportional to specific gravities and might be considered as a primary estimation for hydrocarbon contents. The relationship between trace metals and American Petroleum Institute (API) values of the samples are inversely proportional where the increasing API value of crude oil samples means a decrease in the metal contents of the samples. The method of dry ashing- acid dissolution (DA) was implemented.  The results concluded that crude oil samples of the Kurdistan region have a low metal content. Nevertheless, they could be seen as an essential health hazard for humans and the environment. In t-Test ?  for iron, chromium and lead, there is no relationship between these three heavy metals.
