3 Water Pollution
Earths surface is covered by 70 water so why fuss over protecting water
4 The major sources of water pollution
Runoff toxic waste
--- excessive enrichment of a lake etc. with nutrients resulting in growth of organisms and depletion oxygen.
Eutrophication Eutrophication 5 Water pollution
more water pollution
more pressing on the environment
Waste that come from the sewage plant encourage the growth of algae.
Overgrowth of algae water soon becomes algae ridden and oxygen depleted.
6 Water pollution
Toxic waste comes from industrial plants.
industrial processes heavy metals
lead copper cadmium iron and others
released into the water.
poisoned the marine organisms
Heavy Industries 7 Water pollution Consequences
Harm our health
Destroy the ecosystem
Endanger the livelihood of the fishermen
Affect the tourism
8 Noise pollution
unwanted and damaging sound that pollute the environment.
9 The major sources of noise pollution
Aircraft taking off and landing at the airport.
Machinery on construction sites particularly drills and pile-drivers.
Discotheque music radio cassette-recorder television sets etc.
10 (No Transcript) 11 Noise pollution Consequences
Make people nervous
Damage peoples hearing
Lower the living standard
12 Land pollution
Urban development can higher our living standard. However over development may create a lot of waste
Land pollution 13 Land pollution Reasons
illegal dumping of domestic waste
14 Domestic waste
use of plastic bags
Use of non-recycling products
excessive use of pesticides and herbicides
make the soil become infertile
15 Industrial development
Illegal littering of the by-product during the production
16 Land pollution Consequences
Disturb the living of the habitants
Harm the human health
Bring adverse effect to tourism
17 Visual pollution
The poor organized landscape of the cities
Formed by the poor arrangement of the urban settlements.
Example 18 Visual pollution Reasons
The weak urban planning.
the mixed land use may be occurred (the residential land use being too close with the industrial land use)
The underestimated speed of urbanization.
the government cannot makes response to the urbanization to reach the development of the cities.
19 Visual pollution
Poor living standard.
The poor landscape would affect the tourism. (Landscape is one of the important elements affect the tourists decision)
Consequences 20 Air pollution
concentrations of certain substances
high enough to pollute the atmospheric environment.
Air Pollution occur
21 Main sources of pollutants
22 Sources of Air Pollution
23 Air Pollution Consequence
Low level of visibility
greenhouse effect Global warming
24 Solution for Air Pollution
relocate stationary sources of air
pollution away from the main urban
Air Pollution Control Regulations
Air Quality Control Zones
3. Monitoring and detection
stations to measure the amount of
the air pollutants
4. Advice and education
Environmental education to citizens
Air Pollution Index (API) are provided
Improve in engineering
Report polluting vehicles to the police
Cut down the use of electricity
Use mass public transport
27 Solution for Water Pollution
Water Pollution Control Regulations
Water Control zones
The livestock waste control scheme
Construction of sewage collection systems and sewage treatment works
Monitoring station close supervision
1. Cut down the use of water
2. Use less cleansers when washing
Never throw rubbish into the sea or
29 Solution for Noise Pollution
Noise Control Regulations
Guidance to planners aircraft traffic
railways fixed noise sources
Better design and equipment for noise insulation
Roadside noise barriers
1. Report case to police
Keep noise at low level
TV Hi-Fi party
31 Solution for Land Pollution
Recycling of materials
Education to the public
1. Reuse scrap paper and plastic bag
2. Use recycled material
32 Case Study Hong Kong
33 Case study Reasons
Common in owning private cars
Lack of well-planning
Not complete legislation
Lack of civism
34 air pollution
Types of pollution
1. Primary Pollutants Consists of materials dust gases liquids and other solids that enter the atmosphere through natural and human-made events.
2. Industrial Smog
Under the right conditions the smoke and sulfur dioxide produced from the burning of coal can combine with fog to create INDUSTRIAL SMOG
Heavy traffic flow in busy hours especially in CBD.
Intensive Air conditioning
The industries release harmful smog
36 Measures in HK
Educate the people use the mass-public transport.
Establish the electronic railway system
Monitor the situation of Hong Kong air
The monitoring station are widely distributed in Hong Kong.
There are totally eleven general stations and three roadside stations.
37 Land pollution
high population density city.
large amount of population release a large amount of solid waste.
requires a large area of land to accumulate
land pollution occur
38 Measures in HK
Educate people reduce the use of plastic bags
Government educate people to categorize the rubbish
Advocate recycling acts by funding
39 Noise pollution
high population density city makes the noise pollution worse
heavy traffic flow
air conditioning or the mix of the music and television
harm to social harmony
40 Measures in HK
After 1996 the government moved to the new place for the airport which far from the towns
Educate and regulate the people to reduce the noise
41 Water pollution
large amount of solid waste and sewage produced
the reclamations in Hong Kong are vigorous
dredging project before reclamation
Large amount of sewage and solid waste
Intensive Reclamation activities
42 Measures in HK
The water Pollution Control Regulations
The livestock waste control scheme
Sewage treatment plants
Charge the mediate sewage fee
Every citizen should pay their effort to
keep Hong Kong clean
