Along with industrial expansion, arable lands have been gradually degraded or contaminated with heavy metals and organic pollutants in most 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. This will, in turn, bring about a great risk against human health and deteriorate environmental quality in this region.
Codex has proposed a new standard of Cadmium in agricultural products such as rice grain, wheat, vegetable, meat and so forth, and some Asian countries followed suit to change the critical concentrations of heavy metals in soils and crops. However, most of the Asian countries have not surveyed the concentration of heavy metals in soil as well as crop, nor established a similar regulation because of the lack of reliable data.
It is, therefore, a matter of urgency to collect reliable data on heavy metal concentrations in soil and crop from various Asian countries, and to construct a comprehensive database to accommodate all the relevant data as to heavy metals in variety of soils, crops, irrigation water, agricultural supplies, fertilizers and so forth. Based upon this database, a variety of useful information and methodologies are developed for providing safe foods to Asian people.
The symposium will be held as a special session of the 8th ESAFS conference in cooperation with NIAES, NARC, JIRCAS and Japanese Society for Soil and Plant Nutrition.
