Determination of heavy metal contamination from batik factory in different depth in soil using atomic absorption analysis
A study was carried out to determine heavy metal concentration in soil sample from one batik factory located in Kampung Sungai Keladi, Kota Bharu, Kelantan. Five different sites, (site A, B, C, D, E) with each site, six different depth, starting from 10 cm, 20 cm, 30 cm, 40 cm, 50 cm and 60 cm we...

| Summary: | A study was carried out to determine heavy metal concentration in soil sample from one
batik factory located in Kampung Sungai Keladi, Kota Bharu, Kelantan. Five different sites,
(site A, B, C, D, E) with each site, six different depth, starting from 10 cm, 20 cm, 30 cm,
40 cm, 50 cm and 60 cm were collected. Copper (Cu), Cadmium (Cd), Chromium (Cr),
Lead (Pb) and Iron (Fe) were chosen for heavy metals contaminant study. These heavy metal
concentrations were detected by Atomic Absorption Spectrophotometer (AAS). The results
indicated that the amount of Cu was the highest in site A (at 30 cm depth), Cd was the
highest in site A (almost equally in every depth), Cr was the highest in site B (at 50 cm
depth), Pb was the highest in site A (at 20 cm depth), and the last one Fe, was highest in
every site and depth. The depth of the soil gave significant amount of heavy metals due to
the present of plants. This was because the plant roots contained the ability to absorb these
heavy metals. If in a certain soil depth had a various roots of plants, the amount of heavy
metals in soil may be low due to their movement into the roots. However, if a certain depth
had less roots, the amount of heavy metals in soils may be high, due to the heavy metals
could not being absorbed by plants and contaminated the soil in certain depth. In overall, Fe
contained the highest mean concentration, with the average of 4723.500 ppm, followed by
Pb (72.713 ppm), Cu (20.876 ppm), Cr (12.820 ppm) and Cd (0.813 ppm) respectively.
However, the average concentration of these heavy metals were below the U.S. EPA
regulatory standard limit. |
