2. - Main Types of Water Pollution in Hong Kong - Source of Stream Pollution - Source of Marine Pollution - Cause of Water Pollution in Hong Kong - Effect of Water Pollution in Hong Kong - Measures to solve Water Pollution in Hong Kong -Suggestions of Improving the Environment

3. 1. Livestock Farms 2. Factories 1.Factories 2. Transport 3. Reclamation and Excavation 4. Domestic Source

4. Livestock Farms: - the pig and poultry farms produce a large amount of manure - is disposed into the streams with little treatment - brings organic waste and ammonia to the streams - dyeing and bleaching factories often discharge chemical wastes and metals into the streams Factories:

5. Factories: - discharge the hot water loaded with toxic chemicals and metals into sea - pollute the soils on land which are then dumped into sea - oil spillage from ships occasionally contaminates the sea Transport:

6. Reclamation and Excavation: -reduce the rate of flow across the Harbour -pollutants are easily accumulated in the Victoria Harbour - reduces the dissolved oxygen for the aquatic organisms Domestic Source: - human excreta is discharged into the sea

7. -many sources of water pollution -close to one another and in huge amount - lacks of treatment facilities - only 34% of Hong Kong's urban sewage receives primary treatment or better -some illegal connections of waste water pipes to storm- water pipes -waste water will be discharged directly into sea without treatment

8. 2. Cause the rise of red tides which devastate Hong Kong fisheries. The food chain will be affected as well. 1. Pollution reduces the rate of photosynthesis of plants in water and the amount of food resources. So fish productivity is reduced.

9. 3. Many beaches are polluted with solid wastes which means a loss of recreational resource. 4. Due to the polluted beaches, we have fewer places to carry out recreational activities.

10. 4.Drinking water containing pollutants pose hazards to health. Pathogens in water would cause illnesses in human. 5. Consumption of seafood accumulated with pollutants, would also affect our health.

11. 6. Large amount of money is needed to mitigate the damage on the environment by the pollutants. $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $

12. 1. Legislation and monitoring The Water Pollution Control Regulations set the standards of water quality. - The Water Pollution Control Regulations set the standards of water quality. - The harbours of Hong Kong are divided into ten Water Control Zones for better monitoring. - The harbours of Hong Kong are divided into ten Water Control Zones for better monitoring. - The livestock waste control scheme has been implemented. - The costs of treatment are borne by the polluters. ( Government )

13. - Make sure that you take great care not to overuse pesticides and fertilizers. This will prevent runoffs of the material into |nearby water sources. - Conserve water. This helps prevent water shortages and reduces the amount of contaminated water that needs treatment. - Don’t throw litter into rivers, lakes or oceans.

14. -HK has a heavy burden in landfills -further encouraged and improved -should be pushed towards city wide -limited household waste -push towards to using natural gas for public transport -sign agreements -further improving the environment standards in China

15. -unique pollution in HK -encourage to reduce -better and more environment friendly urban design: more trees, more parks, more leisure, more greeneries -buildings and apartments shouldn't be built so close
