Abstract
Abstract Purpose – The purpose of this research is to investigate the relationship of lead (Pb) and zinc (Zn) contents in sediment of Faunus ater (F. ater) population density and to analyze the relationship between Pb and Zn accumulation in F. ater with F. ater density in Reuleng River, Leupung, Aceh Besar. Design/Methodology/Approach – Sampling was conducted in November 2016 until January 2017. Density of F. ater was analyzed by density formula while its relationship to Pb and Zn in sediments and F. ater was conducted by correlation analysis method. Findings – The results showed that correlation between Pb and Zn in sediments and in F. ater varies at each locations on every month of sampling. Pb and Zn content in sediments found a fluctuating relationship in each month of sampling with density of F. ater. Correlation of Pb content in sediments with F. ater density showed a medium correlation in January 2017 with r-value = 0.665. Zn in sediment has a very strong correlation to F. ater density in November 2016 with r-value = 0.891. Pb in F. ater has a medium correlation to F. ater density in January 2017 with r-value = 0.436. Furthermore, accumulation of Zn in F. ater to its density does show some apparent correlation in each month of sampling. Research Limitation/Implications – This research gives information about the relationship of Pb and Zn contents in sediment to density of F. ater and to analyze correlation of Pb and Zn in F. ater to density of F. ater in Reuleng River, Leupung, Aceh Besar district. Originality/Value – This is the first time research is conducted about on the correlation between lead and zinc to obtain the density of F. ater.
Highlights
The Reuleung river lies in Leupung, Aceh Besar that crossed several villages in the area of Leupung
Pb in the sediments and F. ater in November and December sampling indicates that the metal content of both the sediments and the F. ater was too small
Analysis in January showed a very significant increase, wherein Pb in sediment was found to be 60.732 mg-Pb/kg (Station 1), 51.096 mgPb/kg (Station 2), and 60.097 mg-Pb/kg (Station 3) (Table 1). This difference happened in the research areas because of the ecological conditions in November and December marked by occurrence of several extreme storms resulting in unstable water currents
Summary
The Reuleung river lies in Leupung, Aceh Besar that crossed several villages in the area of Leupung. Land use around this river are for agriculture and human settlements, while the water is utilized for irrigation, fishery, and car washing. Faunus ater is a black snail found in this river (Figure 1). People use these snails as an additional food and sources of their income, sold in many traditional market because it can be consumed and contains high level of protein. F. ater is a mollusc of antrophoda phylum They play significant roles in the public and veterinary health and need to be
