| Goal and objectives of the project | - Identify the generation source and quantify the density of marine litter on some beaches in the South Central coastal region;
- Build the monitoring model marine litter in the South Central coastal region (Pilot in a specific local region);
- Suggest some solutions to reduce environmental pollution in the South Central coastal region. |
| Main results | - Theoretical results:
This project investigated and identified the source of marine waste in the coastal area of the South Central region (Da Nang, Nha Trang, Quy Nhon). The sources of marine litter from the mainland accounts for about 80% of the total amount of marine litters and the sources of marine litter at the sea accounts for 20% of the total amount of marine litters. Identify the source of marine litter by industry. The sources of marine litter are followed in the following order: fisheries > public litter > non-sourced > shipping > medical > fly tipted. Of which, the majority of marine litter originates from fisheries and public, accounting for 43% and 34% respectively of total amount of marine litter.
Investigate and evaluate the current status of marine litter pollution in the South Central coastal area with 21 sampling units at beaches and 01 river mouth. The density of marine litter on the beaches is from 0.005 n/m2 to 1.054 n/m2. The beaches in this area are considered cleaner than other beaches in the country and around the world. Plastic waste accounts for the main component compared to total marine litter (97%), the remaining components include: rubber, textiles, metal, paper, glass and other types accounting for a small remaining percentage. Marine waste of macro and meso sizes accounts for the main component, about more than 99% of the total amount of marine litter.
The total amount of marine litter observed on Han river mouth is 446 items, with density from 500 n/km2 to 1875 n/km2. The density of floating marine litter in the dry season tends to be higher than in the rainy season.
This project has built a marine litter monitoring model in Da Nang city. The location of the KV1 marine litter monitoring sampling unit has coordinates of 4 points (16.0738, 108.18677; 16.07362, 108.18771; 16.07384, 108.18774; 16.07402, 108.18684) on Da Nang Bay beach with a length is 100 m, width is 25 m. Sample collection is carried out in two seasons (rainy season in December, dry season in July), the time for one sample collection period lasts from three to seven days. A list of marine litter has been established for the South Central region.
To minimize marine waste pollution, localities in the South Central coastal region need to implement and comply well with the Party’s policies and laws. It is necessary to develop an action plan to reduce waste pollution locally, paying special attention to solid waste management solutions in the fisheries and urban, raising people’s awareness of harmful effects.
- Applied results:
Applying the marine litter monitoring model in the coastal Da Nang area to observe actual data on marine litter and assess the trends in marine litter in sea environmental. |
| Novelty and actuality and scientific meaningfulness of the results | The project has been combined investigations, surveys, and data collection methods with computational models for the spread of marine litter to build the first monitoring model marine litter in Vietnam. |
