  •   There  are  five  Quaternary  sedimentary  sequences  in  the  Red  River  Delta,  Vietnam.  The  forming of each sequence is related to transgression and regression phases. The sequences, which  was  formed  in  transgression  period,  composed  mainly  of  fine  grained  size  leading  to  the  water  bearing capacity is very low and plays a role as aquicludes. Besides, in these fine grain size layers,  the contents of arsenic and iron are high, especially in dark clay, silty clay rich in organic material ...

  • The living organism which will be deeply affected are shredders, which feed on coarse sedimentary detritus, and collector-gatherers, which feed on fine sedimentary detritus, were the macroinvertebrate functional feeding groups are most adversely affected. Furthermore, during the industrial process, high amount of hydrofluoric acid (HF) are used to separate different sandy materials which are subsequently used for manufacturing glass at industrial plants. Therefore, high concentration of fluoride ion and suspended inorganic matter discharged by the industrial into the study site....
