Dear Delegate

Dear Delegate,

Urban areas continue to be recipients of heavy metal deposits issued from remote sources such as vehicle emissions, waste disposal, industrial discharges, energy production and other human related anthropogenic activities. With rapid industrialisation and urbanisation, heavy metal pollution in urban soils, urban road dusts and agricultural soils has become a pertinent issue over the last two decades

Urban soils are a critical component of the urban ecosystem and heavy metals are the common contaminants in the urban soils and usually come from anthropogenic activities. Various physic-chemical and biological factors control the mobility of these metals in the soils.

This conference aims at providing a forum for discussing the practical strategies for the remediation of soils that have been contaminated with heavy metals in Africa. The conference will further provide insight into the level and source of trace metals from the different urban areas in Africa and the corrective action being taken to minimise the potentials risks to human health in areas identified to be having a high concentration of heavy metals.

Human activities have drastically changed the balance and biochemical and geochemical cycle of some heavy metals. For quite some time, the concentration of heavy metals in the soil has been an issue of great concern not only to ecologists, biologists and farmers but also to environmentalists. An assessment of the environmental risk due to soil pollution is of particular importance for agricultural and non-agricultural areas, because heavy metals which are potentially harmful to human health persist in soils for a very long time. In addition and according to soil parameters they may enter the food chain in significant elevated amounts.

A good understanding of urban soil contamination with metals and location of pollution sources due to industrialisation and urbanisation is important for addressing many environmental problems.

This inaugural conference will tackle the challenges associated with the remediation of contaminated soils.

We look forward to your participation at this event which has already promised to be a huge success.

Kind regards

AMC International

About Your Facilitator

Professor Patrick Ndakidemi is a plant and soil expert currently employed as a professor in the school of Life Sciences and Bioengineering at the Nelson Mandela African Institute of Science and technology (NM-AIST) since April, 2011. His research interests focuses on understanding the adaptation and physiological mechanisms of plants growing in highly intensified cropping systems in nutrient poor soils of Tanzania involving cereals and legumes. In these systems, nitrogen and phosphorus are the most limiting factors to productivity. He is interested in addressing issues related to N and P nutrition of crop plants (Legumes and cereals) grown inn nutrient poor soils of Tanzania. This includes the establishment of adaptation mechanisms involving roots and root exudates that may allow them to survive in such systems.
