Distribution Of Heavy Metals In Mangrove Sediment At The Tha Chin Estuary, Samut Sakhon Province, Thailand, Supaporn Buajan, Nathsuda Pumijumnong
Applied Environmental Research
The concentrations of selected heavy metals (Cd, Cu, Pb and Zn) at a depth of 0-30 cm sediments from 11 stations in a mangrove forest at Bang Ya Praeg, Tha Chin Estuary, Samut Sakhon Province, Thailand were examined. The ranges of heavy metals, in mg kg-1 dry weight (dw), were as follows: Cd (0.035 to 0.070), Cu (7.90 to 21.91), Pb (11.91 to 25.74) and Zn (55.99 to 75.05). The dry season (April 2009) had higher levels of heavy metals than the wet season (August 2009). Heavy metals in the study area had the following order of prevalence: Zn > Pb …
