Water Problem

• 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

• 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

• 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

students,

we must together find a

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.

We can anounce for everyone about the changing of

environment

Take part in environmental

protection programs

 Protecting the environment

is everyone's

Let’s do together,

because the Green and

Clean Environment

That’s all I have to say about solution with Government power
