A mangrove transect (M-M') and a bald beach transect (B-B') were selected in Dongzhaigang National Nature Reserve, China for conducting a comparative study about groundwater chemical characteristics. It was found that the average concentration of Cl- in groundwater sampled from M-M' was much lower than that of B-B'. However, concentrations of heavy metals Ba, Mn, Pb, Sb in groundwater of M-M' were significantly higher than those of B-B'. The average concentrations of Ba, Mn, Pb, Sb were 0.13, 0.83, 0.25 and 0.32 mg/L in M-M', respectively, and 0.09, 0.27, 0.19 and 0.21 mg/L in B-B', respectively. Both transects were affected by the human activities such as aquacultures. The high concentration of Sb in the groundwater of transect M-M' may be mainly due to high concentration of Sb in the Yanfeng River. The higher concentrations of Ba, Mn, Pb in groundwater in M-M' might be attributed to the accumulating and enriching effects of the mangrove systems on heavy metals. The mechanism of accumulating and enriching need to be further investigated in the future.
