The potential of using clay brick as filter was conducted through this study. It is used as filter media in tend to reduce the pesticide concentration in water. There are two method were applied during conducting acute toxicity study which is soaking or submerge method and filtration method. This experiment was conducted for three concentrations and different loading which are 35, 50 and 100 μg/L and 0.1, 0.2 and 0.3 kg/L respectively. The observation of mortality on fish was conducted during experiment that was conducted up to 96-h. The result was exhibit at 100 μg/L concentration clay brick was effective in reducing pesticide concentration in water with increasing loading by using filtration method. However, for 35 μg/L and 50 μg/L concentration, the result was not reliable due high mortality was recorded with increasing loading by using soaking method. Other than that, LC50 for half mortality concentration was perform at three different forms which is at different exposure period, different loading and comparison of untreated and treated water. There are no LC50 values were recorded at different exposure period (24, 48, 72 and 96-h). Meanwhile, for different loading of 0.1 and 0.2 kg/L, the value of LC50 at 35 and 50 μg/L concentrations was zero except for 50 μg/L of 0.2 kg loading which has the LC50 value of 1.56 μg/L (inverse log =36.31 μg/L). The LC50 value for 100μg/L for 0.1 kg loading is 1.96 μg/L (91.20 μg/L) and zero for 0.2and 0.3 kg/L. LC50 value of untreated and treated water at 35 μg/L concentration of endosulfan cannot be determined as all mortalities are less than 50%. Meanwhile for 50 and 100 μg/L the value of LC50 for treated sample is 1.66 μg/L (45.71μg/L) and 0, while for untreated is 0 and 1.88 μg/L (75.86 μg/L). 2016-07-28T08:34:02Z 2016-07-28T08:34:02Z 2015-06 Learning Object http://dspace.unimap.edu.my:80/xmlui/handle/123456789/42398 en Universiti Malaysia Perlis (UniMAP) School of Environmental Engineering
