Abstract

The coastal area of Quang Tri province is less affected by socio-economic development but it was affected by oil spill environmental incidents and the Formosa in the period 2015 - 2019. For risk zonation and environmental risk assessment on coastal area of Quang Tri province, quantitative research method and approaches of Circular 26/2016/TT-BTNMT have been applied. Within the coastal area of Quang Tri province, 1,631 cell of near the shore and 83 cell of coastal areas have been identified, classified and zoned risk and assessed environmental risk. The results show that the environmental risk in the coastal area of Quang Tri province is medium – small level, 84% for near the shore and 99% for coastal areas. Besides, the number of locations with small levels of pollution or low environmental risk is significantly high compared to locations with high environmental risk.
