Abstract
The farming activities in the intensive paddy field hadexcessively used theagrochemicals such as the phosphorous fertilizer and contributed to the increasing of heavy metal in the paddy field such as Lead (Pb) and Cadmium (Cd). The contamination poses serious problems due to affect the soil quality and agricultural products. This research aimed to investigate the accumulated of Pb and Cd in the soil and rice based on the utilization age of paddy field. The soil and rice samples were collected in the intensively paddy field used for 20, 40, 60 and 80 years in MusiRawas regency- South Sumatera-Indonesia. The concentration of Pb and Cd were measured by Atomic Absorption Spectrophotometry (AAS). The correlation between the heavy metal concentration and the utilization age of paddy field were analyzed using the linear regression test. The results showed that the increasing of the utilization age had suffered frommoderate to high heavy metal contamination. The highest concentration of Pb and Cd were at the utilization age of 80 years i.e. 20.56 ppm dan 0.72 ppm for the soil sample and 3.11 ppm and 0.29 ppm for the rice samples, andconcentration of Pb and Cd were at the utilization age of 20 years i.e. 2.35 ppm and 0.15 ppm for the rice samples. The results showed that the heavy metal contaminated the soil and rice had exceeded the maximum concentration regulated by WHO and need the further treatment to maintain the contamination.
