Water Problem
Vocabulary • Agricultural : (thuộc) nông nghiệp • Enterprises : doanh nghiệp • Residential : dân cư
Causes of water pollution
• Saigon river is also polluted by industrial and
agricultural waste water from small-sized
enterprises along the river which is to 65.000
cubic meters a day.
• Residential waste water another pollution
factor. Everyday, 74.800 cubic meters of
waste water in dumped into the river from
residential in localities, with over 90% of the
waste coming from Hồ Chí Minh city.
• That is equivalent to only less than 20% of
household waste collected and treated due to
the limited number of waste water treatment
plants, the rest is discharged into the river.
• In addition, the production bose is located
outside the industrial zones also discharged
into the river basin Saigon 45.000 cubic
meters.
• Including hazardous
industries such as paper
production 7.700 cubic
meters and textile 4.200
cubic meters. As for
livestock operations per
day discharged than
24.500 cubic meters
waste water.
Effects of water pollution
• General consequences of water pollution is
the proportion of people who suffer from
acute and chronic diseases related to water
pollution, such as conjunctivitis, diarrhea,
cancer. People living around polluted areas
increasingly suffering from a variety of
disease suspected of being due to the use of
dirty water in all activities.
Air Problem
Vocabulary
• Atmosphere: khí
quyển
• Particulate: hạt bụi • Bronchitis: viêm phế
quản
• Pneumonia: viêm phổi
• There are several main causes of air pollution,
the vast majority of them can be attributed to
man.
• Air pollution is the introduction into the
atmosphere of chemicals, particulates, and
biological matter that cause harm to humans,
other living organisms, or cause damage to
the natural environment
Causes of air pollution in Ho Chi Minh
• Ho Chi Minh city is big city in Viet Nam and
developing city.
• The factor that contributes chiefly to air
pollution stems for transports, industrial
manufacturing or simply burning coal for
cooking and heating
Situation
• In Ho Chi Minh city air pollution is
accelerating at an alarming rate, every day 320000 cars and 3.2 million motobikes burn millions of liter of fuel, emitting equivalently a massive amount of toxic gas, especially carbon dioxide, particularly in the eastern and North-Western.
• In the Thu Duc and District 9, the dust
density measured surpasses the
permissible level, this is mainly due to
concentration of many industrial park in
the area. The downtown section is no
exception particularly the air pollution
measured daily at different times shows
greater than what is allowable.
Effect of air pollution
• Acidification:
Chemical reactions involving air pollutants can
create acidic compounds which can cause harm to
vegetation and buildings. Sometimes, when an air
pollutants, such as sulfuric acid combines with the
water droplets that make up clouds, the water
droplets become acidic, forming acid rain. When
acid rain falls over an area, it can kill trees and
harm animals, fish, and other wildlife.
• Ground-level ozone:
• Chemical reactions involving air pollutants create a
poisonous gas ozone (O3). Gas Ozone can affect
people’s health and can damage vegetation types
and some animal life too.
• Effect to health:
Short-term effects include irritation to the eyes, nose
and throat, and upper respiratory infections such as
bronchitis and pneumonia. Others include headaches,
nausea, and allergic reactions. Short-term air
pollution can aggravate the medical conditions of
individuals with asthma and emphysema.
• Long-term health effects can include chronic
respiratory disease, lung cancer, heart
disease, and even damage to the brain,
nerves, liver, or kidneys. Continual exposure
to air pollution affects the lungs of growing
children
Earth Problems
Causes of land pollution
• Increase in urbanization is one of the
major causes of land pollution.
Causes of land pollution
• The disposal of non-biodegradable
wastes including containers, bottles and cans made of plastic, used cars and electronic goods leads to the pollution of land.
Causes of land pollution
• Agricultural wastes including
pesticides and fertilizers affect the land environment.
Causes of land pollution
• Industrial waste is also a major cause lead to land pollution. For example, chemicals and paint.
Causes of land pollution
• Improper treatment of sewage leads
to the accumulation of solids, such as biomass sludge.
Effects of land pollution
• Industrial waste falls to the land to
change the composition of the land.
• Pesticides led to the agro-ecological
imbalance.
• Organic components of the land
decreased rapidly, and the water-
holding capacity and drainage of land
the change.
Effects of land pollution
• The waste persistent unsanitary environment and
landscape, creating conditions for the development
of harmful bacteria to humans.
How to prevent land pollution
• Restricted solid waste, liquid and gaseous. • Limit the use of fertilizers, pesticides. • The factory must waste treatment before being
moved out.
• Propaganda about the harmful effects of
environmental pollution.
• The first , the current in HCM city has
about 11 industrial zone activities
I think the Government needs building industrial zones far from the city and achieve standard of wastewater treatment and emissions
Example existing industrial areas Bien Hoa in Dong Nai province and Song Than in Binh Duong Province is the modern industrial and protect environment.
The second, HCM City have too many vehicles about 5,300,000 vehicles according to statistics in 2011
The Government should limit the increase in new vehicles and management of older vehicles reasonably.
The 3rd, Ho Chi Minh city's population
is currently 7,700,000 people.
Government should limit population increase and migration management , conduct the planning expand the city .
Create more jobs in the industrial park outside the city to solve the population problem focused city.
The 4th , Besides that need execute of the measures as plant more trees in the city
put more can trash in public areas
building system collector and waste treatment reasonable and raise awareness of environmental protection of all people
As a student, how can we do to protect the environment?
The world’s envirome nt is more and more pollute
• As
student s, we must togethe r find a way to save natural, as same as saving our life.
First, students need to be equipped with knowledge about the environment, and know how important of protecting them, why we can’t live without its.
- We must not to throw
garbage away.
- Use bicycle or public transport like bus, train in stead of using invidual- transport.
We should use some devide to save energy.
