Air pollution can be caused by liquids, or gases that make the air harmful to breathe. There are two main types of air pollution: primary and secondary.

Pollution is any contamination of the environment which causes harm to the environment or the inhabitants of the environment. There are three main kinds of pollution. Air pollution can be caused by liquids, or gases that make the air harmful to breathe. There are two main types of air pollution: primary and secondary. Primary pollutants enter the air directly, like smoke from factories and car exhaust. Secondary pollutants are chemicals that mix together to pollute the air, like mixtures of emissions from vehicles and factory smoke that change to form more dangerous pollutants in the air and sunlight.

Soil pollution can be caused by pesticides, leakage from chemical tanks, oil spills, and other chemicals which get into the soil by dumping or accidental contamination. Soil pollution can also cause water pollution when underground water becomes contaminated by coming into contact with the polluted soil. Water pollution can be caused by waste products, sewage, oil spills, and litter in streams, rivers, lakes, and oceans. Some scientists believe that water pollution is the largest cause of death and disease in the world, causing about 14,000 deaths in the world each day.

It is not possible for anyone to predict the exact timing and effects of global pollution and global climate change brought about by pollution. There is general agreement by scientists that the global climate will continue to change, the intensity of weather effects will continue to increase, and some species of animals will become extinct

Nowadays, pollution is a popular term with everyone in the world and air pollution is one type of pollution. The definition of air pollution is one such form that refers to the contamination of the air, irrespective of indoors or outside. A physical, biological or chemical alteration to the air in the atmosphere can be termed as pollution. There are some main reasons which cause air contamination such as burning of fossil fuels, agricultural activities, exhaust from factories and industries, mining operations, and indoor air pollution. Air pollution always has bad effects on our life. Harmful gases, dust, and smoke enter into the atmosphere and make it difficult for plants, animals and humans to survive. We also can see some examples of the result of air contamination which occurs around us as global warming, acid rain, and depletion of ozone layer. The effects of air pollution are alarming, so governments over the world should have suitable policies of protecting the environment, especially air quality to create a clean world for our generation in the future.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 36 to 42.

Environmental pollution is one of the impacts of human activities on the Earth. Pollution occurs when pollutants contaminate the natural surroundings; which brings about changes that affect our normal lifestyles adversely. Pollution disturbs our ecosystem and the balance in the environment. Pollution occurs in different forms; air, water, soil, radioactive, noise, heat/ thermal and light Let us discuss the causes and effects of air pollution on mankind and the environment as a whole.

Air pollution is the most prominent and dangerous form of pollution. It occurs due to many reasons. Excessive burning of fuel which is a necessity of our daily lives for cooking, driving and other industrial activities; releases a huge amount of chemical substances in the air every day; these pollute the air. Smoke from chimneys, factories, vehicles or burning of wood basically occurs due to coal burning; this releases sulphur dioxide into the air making it toxic.

The effects of air pollution are evident too. The increase in the amount of CO2 in the atmosphere leads to smog which can restrict sunlight from reaching the earth. Thus, preventing plants in the process of photosynthesis. Gases like sulfur dioxide (SO2) and nitrogen oxide (NO) can cause acid rain.

The decrease in quality of air leads to several respiratory problems including asthma or lung cancer. Chest pain, congestion, throat inflammation, cardiovascular disease, respiratory disease are some of diseases that can be caused by air pollution.

The emission of greenhouse gases particularly CO2 is leading to global warming. Every other day new industries are being set up, new vehicles come on roads and trees are cut to make way for new homes. All of them, in direct or indirect way lead to increase in CO2 in the environment. The increase in CO2 leads to melting of polar ice caps which increases the sea level and pose danger for the people living near coastal areas.

Ozone layer is the thin shield high up in the sky that stops ultra violet rays from reaching the earth. As a result of human activities, chemicals, such as chlorofluorocarbons (CFCs), were released into the atmosphere which contributed to the depletion of ozone layer.

Question 40: According to paragraph 5, air pollution contributes to the greenhouse effect which can lead to

A. global warming

B. polar ice melting

C. increase in CO2 in the environment

D. global warming, polar ice melting, rise of sea levels and danger for people

Đáp án A.

Có thể suy ra điều gì từ đoạn văn?

A. Đời sống của chúng ta càng trở nên hiện đại, vấn đề ô nhiễm càng trở nên nghiêm trọng.

B. Con người có thể sớm kiểm soát vấn đề ô nhiễm không khí trong tương lai.

C. Chỉ có ô nhiễm không khi mới nguy hiểm và có những ảnh hưởng tiêu cực đến con người và môi trường.

D. Khí CO2 là nguyên nhân của việc suy giảm tầng ozone.

Tạm dịch

Ô nhiễm môi trường là một trong những tác động của hoạt động con người vào trái đất. Ô nhiễm xảy ra khi các chất ô nhiễm gây ô nhiễm môi trường tự nhiên; mang lại những thay đổi ảnh hướng đến lối sống bình thường của chúng ta. Ô nhiễm gây rối loạn hệ sinh thái của chúng ta và sự cân bằng trong môi trường. Ô nhiễm xảy ra ở các dạng khác nhau; không khí, nước, đất, phóng xạ, tiếng ồn, sức nóng/ nhiệt và ánh sáng. Hãy để chúng tôi thảo luận về nguyên nhân và ảnh hướng của ô nhiễm không khí đối với nhân loại và môi trường nói chung.

Ô nhiễm không khí là dạng ô nhiễm nguy hiểm và nổi bật nhất. Nó xảy ra do nhiều lý do. Việc đốt cháy nhiên liệu quá mức cần thiết cho cuộc sống hàng ngày của chúng ta để nấu ăn, lái xe và các hoạt động công nghiệp khác; giải phóng một lượng lớn chất hóa học trong không khí hàng ngày; những chất này làm ô nhiễm không khí. Khói từ các ống khói, nhà máy, xe cộ hoặc đốt gỗ về cơ bản xảy ra do

đốt than; điều này giải phóng sulfur dioxide vào không khí làm cho nó độc hại.

Các tác động của ô nhiễm không khí cũng rất hiển nhiên. Sự gia tăng lượng CO2 trong khí quyển dẫn đến khói bụi có thế hạn chế ánh sáng mặt trời chiếu vào trái đất. Do đó, ngăn chặn thực vật trong quá trình quang hợp. Các loại khí như sulphur dioxide và nitơ oxit có thể gây ra mưa axit.

Việc giảm chất lượng không khí dẫn đến một số vấn đề hô hấp bao gồm hen suyễn hoặc ung thư phổi. Đau ngực, nghẹt mũi, viêm cổ họng, bệnh tim mạch, bệnh hô hấp là một số bệnh có thể là nguyên nhân gây ô nhiễm không khí.

Sự phát thải khí nhà kính đặc biệt là CO2 đang dẫn đến sự nóng lên toàn cầu. Mỗi ngày các ngành công nghiệp mới đang được thiết lập, xe mới đi trên đường và cây cối bị chặt để nhường chỗ cho những ngôi nhà mới. Tất cả chúng, theo cách trực tiếp hoặc gián tiếp đều dẫn đến gia tăng CO2 trong môi trường. Sự gia tăng CO2 dẫn đến sự tan chảy của các chỏm băng cực làm tăng mực nước biển và gây nguy hiểm cho những người sống gần các khu vực ven biển.

Lớp ôzôn là lá chắn mỏng trên bầu trời cao ngăn tia cực tím chiếu vào trái đất. Bởi vì các hoạt động của con người, các hóa chất, chẳng hạn như chlorot1uorocarhons (CFCs), được giải phóng vào khí quyển góp phần làm suy giảm tầng ôzôn.
