Concentration of Some Metals in Water and Soil Samples at Some Locations near the Hotmud Flow at Porong Disaster Area, Sidoarjo, East Java, Indonesia.

[摘要] More than hundred thousands people in the Porong subdistrict have been displaced by the hot mud flowing from a natural gas well being drilled by Lapindo Brantas, an oil well company since late May 2006. The mud was estimated to be flowing at a rate of 125,000 m3 per day and rapidly flooded surrounding areas displacing hundred thousands of people. For about thousand people had to seek medical treatment after exposure to and inhalation of a poisonous gas. This disaster is happen continue until now. The monitoring of mud flow and water quality are performed by taking separate samples in the field and transporting the samples to the laboratory for analysis. The sediment and water samples of hot mud flow at Porong Area, East Java, Indonesia, were taken from several points and analyzed are as follow; concentration of Cr, Cd, Zn, Cu, Pb, Fe in sediment samples in the range of : 0.26-0.42; 0.16-0.34; 54.80-61.10; 21.22-24.16; 3.45-9.83; 1314-1526 ppm respectively. And concentration of Cr, Cd, Zn, Cu, Pb, Fe in water sampels in the range of : 0.14-0.27; 0.001-0.002; 0.19-0.42; 0.012-0.036; 0.26-0.36; 0.20-0.58 ppm respectively. The soil and water samples were taken from several locations near the hot mud flow at Porong Area, East Java, Indonesia and the concentration of Cr, Cd, Zn, Cu, Pb, Fe in soil and water samples are not detected.
