Abstract
The paper presents the results of monitoring some basic environmental factors in the Can Gio environmental monitoring station in the period 2009-2019. The environmental parameters like temperature, salinity and pH, total suspended solids, dissolved oxygen, biochemical oxygen demand, nutrient concentrations (NH4+-N, PO43--P) were collected and analyzed twice a month (both of high tide and low tide). Based on the results at the two monitoring stations, the coastal water quality in the study area changes seasonally, especially depends on the tide. The combination of rainy season and the low tide created a falling in the parameters of salinity and dissolved oxygen, whereas total suspended solids was high. Water temperature was found to be in the range of 27-30.6°C; salinity ranged between 20 and 29.5‰. The pH were found to be neutral and had decreasing features in recent years, whereas salinity was opposite. The recorded variation dissolved oxygen concentration in the study area was 3.9–5.9 mg.l-1, with the lowest level at low tide. Generally, the environment in the study area was not polluted yet. However, at Long Hoa station C2, the value of of biochemical oxygen demand, phosphate and ammonia were higher than these which in Cau Den station C1. This shows that Can Gio area has a potential risk of partial pollution.
