Measuring and modeling heavy metals (Ni,Pb,Cd,Co,Hg) in seashore sediments of Asaluyeh Region ( Nayband Gulf)

This research intends to study the rate of accumulation of heavy metals and calculate the rate of pollution of seabed sediments in sampling and analyses as a result of large industrial activities in Asaluyeh region. The in Asaluyeh region in the Persian Gulf, due to its exceptional position, where a great number of gas refineries and petrochemical plants are established, is directly or indirectly exposed to different organic and mineral pollutants. Taking into consideration the position of the region, this study was conducted in 2013 in 10 stations, to study the pollution resulting from the heavy metals of Cobalt, Cadmium, Lead, Nickel, and Mercury. Sediment samples were collected by Ekman Grab and measurements were made by a furnace atomic absorption device. Furthermore, the obtained data were modeled with fuzzy logic. The comparison of the results obtained from modeling with the data resulting from lab measurements, indicates the suitable efficiency of fuzzy logic in forecasting the quantities of heavy metals density.
