Daftar Isi:
- The research is focused on lead contamination assessment in soil of Yogyakarta city and surrounding area. Lead is one of heavy metals, which commonly originated from human activities and lithogenic. However, human activities usually produce higher probability of lead concentration. The heavy metal concentrations in contaminated soils have been examined increased the concentrations in smaller-sized particles. Lead concentrations in soil are related to soil particle size, as mentioned above. The main objectives of this research are to recognize the soil types in study area and the level of lead concentration content in soil, to understand the correlation between lead and soil types and to understand relationship of lead, soil types, and the sources of lead contaminated in soils (Landuse). The 36 soil samples were taken in Yogyakarta city and surrounding area. The soil type was analyzed by hydrometer and sieving method, and was classified by the USDA soil texture system. In addition, lead concentration was examined by Atomic Absorption Spectrometry (AAS). The value of lead concentration was plotted in the graph to show the correlation between soil particle size and lead concentration. To understand the relationship of soil types, lead concentration and landuse were displayed by the stock graph. Consequently, base on soil analysis, the soil types in Yogyakarta city are mostly sandy loam and loamy sand. Moreover, the result of lead concentration in soil of Yogyakarta city ranged 15.08 to 35.3ppm and 7.6 to 51.18ppm in soil of surrounding area. The relationship of soil particle size and lead concentration was shown in the graph by trendline that showed progress. The correlation coefficient of graph is 0.55 to 0.73. It showed that the small particle size soil contains higher lead concentration than bigger particle size soil. The higher potential contaminant loading in this research occurs, the traffic area and the main source is from the smoke of vehicle. To sum up, higher or less lead concentration in contaminated soils depends on landuse activities and soil ability to absorb lead concentration.
