Determination of Some Metal Concentrations in Plankton of Engineering and Built Environment Lake Faculty - UKM, Bangi - Malaysia during 2019

Abstract

A study of metal concentrations in plankton of Engineering and Built Environment Lake Faculty - UKM, Selangor, Peninsular Malaysia was conducted in January, April, July, and October 2019. Mixed plankton (phytoplankton and zooplankton) was collected randomly at different locations from the water lake by using 240 µm plankton net and these samples were pooled together. After cleaning the plankton samples were washed with tap water followed by distilled water and filtered by 0.45 µm membrane filters. Six metals i.e. cadmium, chromium, lead, nickel, zinc, and copper were determined in the plankton of the lake. The metals concentration were determined by Inductively Coupled Plasma Mass Spectrometer (ICP –MS), Perkin Elmer Elan, Model 9000. Furthermore, metals concentration in plankton for Zn,Cu,Cr,Ni,Pb and Cd were (6.30,4.70,2.47,2.40,0.52 and 0.06) respectively.
