| Summary: | Woody plants that capable to grow in extreme conditions such as in anaerobic muddy soil, high
salinity, rough winds, hot and humid weather are commonly called mangrove plants. These mangrove
creatures usually can be found in tropical and subtropical area; between land and sea.Elevated
concentration of heavy metals in sediment have detrimental consequences
on enviromental.This study was conducted to response to environmental problems of
Malaysia. Thus, the objectives of this study were: (1) to detemine status of heavy metals contents
in sediment at Sungai Sepetang and Sungai Tiram laut, Perak; (2) the specific objective to assess
and compare of heavy metal contents in sediment at Sungai Sepetang and Sungai Tiram laut; (3)
Comparison of the data analysis according to different national and international
standards. For this research, the samples were collected during the wet season. A total of 150
sediment samples were collected with different depth (of 0-15 cm, 15-30 cm, 30-50 cm,
50-100 cm, and >100 cm) from upstream, middle stream, and downstream of river at each
study area.To determination and level of five heavy metals (Zn, Fe, Cd, Pb, and Cu) from Sungai
Sepetang and Sungai Tiram laut, and for the portion of sediment which passing through the 2mm
sieve were determined the study.The metal contamination in sediment are also evaluated by
applying Geo-accumulation Index (I-geo). The results showed that the sediment at Sungai Sepetang
was sandy loam clay at all depths and the sediment at Sungai Tiram Laut was sandy loam. The
sediment pH of this area was acidic, where the soil at the deepest level showed a low pH. As for
electrical conductivity (EC) at Sungai Sepetang and Sungai Tiram Laut, the range was from 17.239 to
17.871 dS/m. Furthermore, both rivers showed concentration of the heavy metals Cu, Pb, and Fe;
however, Cd and Zn were not detected. The results also revealed that Sungai Sepetang had a
higher concentration of heavy metal than Sungai Sepetang , Where the contamination of sediment was higher (Fe) in zones and depth. Based on result
, the comparison the concentration of heavy metal in sediment with different zones and depth at
Sungai Sepetang and Sungai Tiram Laut was found that Copper (Cu), Lead (Pb),and Iron (Fe)
are not dangerous in sediment from other studies .I-geo index demonstrated that most of the
embraced metal have index value below zero.This shows the river sediment is unpolluted.The
present study on heavy metal concentration in the sediment of Sungai Sepetang and Sungai
Tiram Laut, Matang Mangrove Forest Reserve, will be useful for rational planning of
contamination control
strategies and their prioritization. |
