MVPT for visual-perception tests of children. WISC and VMI tests of children. As we found very few controls, we had to use a cut-off point of 2.0 ppm to divide case and control in order to analyze the association between intelligence and the level of arsenic in hair.

New Irrigation System Completed A water irrigation project, called Wang Siralug, was completely constructed by the Depart-ment of Water Irrigation, in order to provide new water sources for the villagers in Ronpibool District. The community pipe system from this new water irrigation is now underway and is expected to be finished by the end of 1996. The rest of the villagers could use water from the government pipe system of the Sanitary District Authority and rain water kept from the rainy season. The hole will be covered with cement and soil. This area will then be utilized for a public park and tourist sight-seeing.
