Abstract

Lapindo mud has led to increased levels of heavy metals in aquatic ecosystem at eastern coastal Porong, sidoarjo, East Java, and therefore contributes to the heavy metals content in fish, especially cadmium and lead. This research aims to (1) determine levels of Cadmium and Lead in waters polluted by Lapindo mud, (2) analyzing the content of Cd and Pb in fish living in waters polluted by Lapindo mud, (3) determine the status of fishery product food safety on the farm affected Lapindo mudflow, ( 4 ) determine the recommendation for a solution. Research conducted by observation analytical method. Purposive sample was determined by Lapindo mud pollution maps. Location of research include aquatic ecosystem in Porong, Jabon, and Tanggulangin, Sidoarjo, which is divided into 5 sub locations namely: aquatic ecosystem around the Lapindo mud embankments reservoirs, fish ponds in the Reno Kenongo village, river in the Gempolsari village, brackish water ponds in the Tegalsari village, and ponds in the Permisan village. At each specified sub location, data collection 4 stations, each station is done 3 times repetition. Analysis of the levels of Cd and Pb doing in the Balai Besar Laboratorium Kesehatan Laboratory (BBLK) Surabaya with the method of Atomic Absorption Spectrophotometer (AAS). Data were analyzed descriptively qualitatively and comparing to the Standard Quality (East Java Governor Decree No.45/2002; Kepmen LH No.51/2004; PP.No 82/2001). The results showed the levels of Cd and Pb both in the water and the fish that live in waters polluted by Lapindo mud has exceeded the threshold value quality standard. Levels of Cd in water 0.018–0.080 ppm (>0.01 ppm), and Pb 0.013-0.074 ppm (>0.03 ppm). Cadmium concentration in fishs 0.037- 1.542 ppm (>0.001 ppm), and lead 0.179-1.367 ppm (>0.008 ppm), so it does not meet food safety standards. It is necessary for heavy metal remediation.
