Bioremediation of Heavy Metals from Aqueous Solutions by Some Fungi : Biosorption of lead and cobalt ions

Heavy metals pollution has become a more serious environmental problem in the last several decades because of their toxicity to the environment. Lead pollution is a serious environmental problem in many countries, caused by some industrial activities, and poses a significant threat to the environment and public health. In addition, cobalt may cause health problems in living cells at high levels. The removal of heavy metals from the environment especially wastewater is now shifting from the use of conventional adsorbents to the use of biosorbents in a process known as biosorption.
