Abstract

Abstract. Heavy metal content in water always changes depending on lithology and disposal of contaminated waste. Heavy metals are difficult to decompose in water and are easily bound in sediment so that the more sediment accumulation, the greater the heavy metal content. Heavy metals have toxic effects on humans and other livings, accumulate in the body of an organism and stay for a long period. This compound can lead to a decrease in water quality which will affect the fishery and in pond cultivation. One of the important heavy metal pollutants is lead (Pb), which is usually came from many sources. The purpose of this study was to determine the concentration of lead in seaweed, pond water, and sediment. This research was conducted in March 2018 from 6 pond stations. This research was conducted using descriptive and statistic analysis. Analysis of Pb compound is done using AAS (Atomic Absorption Spectrophotometry). The results of the analysis of Pb content in seaweed ranged between 0.0163-0.1377 mg/ kg. Pb content in pond water range from 0.0087 -0.0137 mg / lt and the Pb content in sediment range between 1.2703-2.3594 mg/ lt. Based on the analysis, the Pb content is most abundant in sediments where the Pb content has exceeded the threshold value (SNI) of 0.3 mg/kg. Pb content on seaweed and pond water are still within the standard value of Pb metal contamination (BPOMRI No. 23 of 2013) which is 0.20 mg/kg. The relationship between Pb content in seaweed to the water is categorized as a weak (R = 0.073), it is similar to the seaweed with sediment (R = 0,28).
