Rhizophora apiculata seedlings were planted in water at salinities of 5 and 25 ppb (parts per billion) with As concentrations of 0, 1, 5 and 10 ppm. Research results showed that the ability of As reduction from water fluctuated in range of 8 - 23 percent. The ability of As reduction was significant differences between treatment of 10 ppm As and treatments of 1 and 5 ppm; the lowest ability was found at treatment of 10 ppm, however the reduction ability was not significant difference between salinities of 5 and 25 ppb. The As contents in Rhizophora apiculata trees ranged from 0.2 - 0.37 and 0.2 - 0.32 mg/individuals at salinities of 5 and 25 ppb respectively. Arsenic concentrations affected on Rhizophora apiculata growth and development in term of: Rhizophora apiculata trees were similar growing between the treatment of 1 ppm and the control treatment; the Rhizophora apiculata growing were limited and inhibited at As concentrations of 5 and 10 ppm through the root development, the root length, leaves number and fresh weights.
