| Summary: | Sodium dodecyl sulfate (SDS) is widely used as surfactant in household products such as toothpaste,
shampoos, bubble foams, cosmetic and detergent. However, SDS may also have detrimental effects after
being discharged into water. SDS can flow into aquatic ecosystem, where it can exert a variety of
physiologically effects in living organisms including fish. This study therefore aimed to investigate the
effect of sub-lethal exposure SDS on zebrafish larvae development. The exposure of SDS was tested on
zebrafish embryo within seven day. The sub-lethal exposure were determined to be in range 9.5 mg/L to
15 mg/L. At concentration 10 mg/L of SDS, there were consistent result that effect the temporal
development. Hatching rate, free swim rate and survival rate of 10 mg/L SDS was significantly reduced
by 37.7% (p<0.05), 19.65% (p<0.05), and 53% (p<0.005) respectively. Besides that, the phenotypic
deformities was observed at the zebrafish that under treatment which include pericardia! edema, yolk sac
edema, vertebrate bent and tail bent. This study revealed that sub-lethal exposure of SDS has capability
for detrimental effect on aquatic organism. Therefore, sodium dodecyl sulfate could seriously damage
the development of zebrafish. |
