Table 2.
Spatial variation of sediment quality parameters in sampling sites during the study period. Data are presented as mean ± standard deviation (SD). Results indicated by different superscript letters in each row are significantly different from each other (ANOVA, Tukey's test, p < 0.05, n=10).
