Pollution emitted in industrial areas represents a threat to human health and the surrounding natural resources. We have a tendency to believe that the production processes are the only source of environmental damage, and often forget about the possible long-term effects of harmful production practices. We may think that the closure of these huge industrial areas would improve the quality of the environment. Unfortunately, this ignores the threat of the remaining waste, which is abandoned and poorly stored. It represents an even bigger danger because it stands neglected as it degrades and leaks into the earth without any control at all.

Changes in the water chemistry due to surface water contamination can affect all levels of an ecosystem. It can affect the health of lower food chain organisms and, consequently, the availability of food up through the food chain. It can damage the health of wetlands and damage their ability to support healthy ecosystems, control flooding, and filter pollutants from storm water runoff. The health of animals and humans are affected when they drink or bathe in contaminated water. In addition water-based organisms, like fish and shellfish, can pile up and concentrate contaminants in their bodies. When other animals or humans eat these organisms, they receive a much higher dose of contaminant than they would have if they had been directly exposed to the original contamination.

Contaminated groundwater can badly affect animals, plants and humans if it is removed from the ground by manmade or natural processes. Depending on the study of rocks of the area, groundwater may rise to the surface through springs or seeps, flow sideways into nearby rivers, streams, or ponds, or sink deeper into the earth. In many parts of fhe world, groundwater is pumped out of the ground to be used for drinking, bathing, other household uses, agriculture, and industry.

Contaminants in the soil can harm plants when they take up the contamination through their roots. Eating, breathing in, or touching contaminated soil, as well as eating plants or animals that have piled up soil contaminants can badly affect the health of humans and animals.

Air pollution can cause breathing-related problems and other bad health effects as contaminants are absorbed from the lungs into other parts of the hody. Certain air contaminants can also harm animals and humans when they contact the skin. Plants rely on breathing for their growth and can also be affected by exposure to contaminants moved in the air.

Which of the followings is the flow of water from the ground to the surface?

A. Streams

B. Ponds

C. Rivers

D. Springs

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.

(Source: https://goo.gl/RpdPw3)

Which of the following can be inferred from the passage?

A. The more modern our lives become, the more serious the pollution is.

B. People can control air pollution soon in the future.

C. Only air pollution is dangerous and has a negative impact on humans and the environment.

D. CO2 is the cause of the depletion of ozone layer.

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.
