Oil and grease concentration in water and surface sediment from FSSA Lake

This study was carried out to determine the concentration of oil and grease (OG) in water and surface sediment of FSSA lake, UMS. The concentration of OG in water and surface sediment was also compared. Sampling was done twice and six sampling stations were chosen. The samples were taken from the wa...
