Analisis Cemaran Logam Berat Merkuri pada Air dan Udang di Sungai Mandor Kecamatan Mandor Kabupaten Landak
Abstract: Mercury used in gold
mining activities in the water of Mandor river in Mandor Disrict of Landak Regency
may couse environmental pollution in form of the degradation of water quality
and pollution to the biota, one of them was shrimp. The shrimp living in Mandor
river was predicted to be polluted with mercury, and if it was consumed, it may
cause health disorders for people, especially those living near the river. This
research had the objectives of finding out the water Hg content and shrimp Hg
content in the Mandor river and finding out the correlation of water Hg content
to shrimp Hg content.
Methode : This research was an observing research with the
cross-sectional design. The sample collection points were at five points with
30 water sample and 30 shrimp samples. The used statistical test was the
product mommet correlation test.
Result: The average of water Hg content was as much as 2,15 ppb ang the
average shrimp Hg content was as much as 0,18 mg/kg. From the test result, the
differences in water Hg content showed that there were differences of water Hg
content in each research location (p value = 0,001); for shrimp Hg content,
there were no different of results among research location except in Kunyit
Village and Kopiang Village that showed differences. From the results of
correlation test, it was found that there was a correlation between water Hg
content to shrimp Hg content ( p value = 0,047; r = 0,366). The regression
result showed the regression coefficient value as much as 0,134 (p value =
0,47); the highest the water Hg content in Mandor river, therefore, the shrimp
Hg content will also increase, and water Hg content influenced on the existence
of shrimp Hg content as much as 10,3%. The analysis result of mercury pollution
in Mandor River show that the downstream area has a higher Hg content compared
to the upstream area, and the shrimp Hg content increases especially in Mandor
Village.
