Organized by:

National Institute for Agro-Environmental Sciences (NIAES)
Monsoon Asia Agro-Environmental Research Consortium (MARCO)

Scope and objectives:

Along with industrial expansion and economic growth, arable lands have been gradually degraded or contaminated with hazardous pollutants such as cadmium (Cd), arsenate (As) and other heavy metals in most of the Asian countries. In the two decades, this trend became obvious, and significantly aggravated the quality of soil and crop because of the increased concentration of pollutants in them. Thus, the Asian countries have paid much attention to contamination of agricultural soils and crops by heavy metals due to their potential effects on human health and long-term sustainability of food production in the contaminated areas. We need promising technologies to handle them.

The aim of the symposium is (1) to clarify the present condition of heavy metal pollution in Asian countries, (2) exchanging the information on state-of-the-art remediation technologies for the heavy metal pollution and (3) discussing the direction of future research and ways to strengthen collaboration for heavy metal contamination in monsoon Asia. This symposium is held as a satellite meeting of the MARCO Symposium 2012.
