The paper aims to investigate the concentrations of Pb, Cd, Cr and Ag element of as well as microbial contamination in computer keyboard within the work environment at the Faculty of Engineering and Technology Sciences (FETS) at Sebha University, Libya. The results showed that the mean elemental concentrations (mg/g) in the samples were Pb (14.2±12.9), Ag (7.49±1.44), Cr (6.09±2.88) and Cd (4.43±1.48). The most commonly found heavy metals were Pb (44.1%), followed by (Ag 23.3), (Cr 18.9), and (Cd 13.8) %. The concentrations were higher than the limits allowed by EPA 2009. The concentration of Cd also exceeded the European …
