In the summer, when traveling from the city of the village, we feel the air in two different areas is very clear. In particular, the city atmosphere is often more severely polluted than rural air, so there is no benefit for psychology and human health. Scientists have studied and indicate different muscle Version in the 2-zone air is as follows: First, the city air often has more bacteria, germs that cause disease in rural areas, because in high-density city, many goods exchange, production and production Building development, creating large, dispersed, difficult to collect timely, causing environmental pollution. People from different regions overcome many, bringing pathogens from many places to arrive. Air circulation is poor because of high-rise houses, also provides opportunities for germs to cause concentration and longer survival

In addition, in rural areas, many green trees create a fresh, pleasant feeling, it is capable of secreting plant antibacterial substances, so the amount of germs cause disease The air is also less than in 2, the city air temperature is higher in rural areas, while humidity is lower. In the summer, the city air temperature can be higher than rural areas from 2 - 6 degrees Celsius, temperature at surfaces covered with brick, concrete higher than air temperature from 5 - 8 degrees
Nhan is due to poor air traffic city, reducing heat dispersion. Many motorbikes, cars travel, many factories, manufacturing enterprises use incinerators, waste lots of heat into the air. atmosphere. Water pond water is small, soil covered with bricks, plastic, concrete does not allow water in evaporating soil, medium without consumption of heat, while making air drier. Behear, in rural areas, air is not covered Beads should be better circulation. Heat-generated waste sources such as much less city. Moreover, the trees are a lot, creating a good coating without the sunlight directly burning the soil and also consumes a solar part for photosynthesis. The ground and the water surface evaporate well, consume the energy from the sun. Air in cities is more and more polluted than rural areas.

The construction, digging, transporting materials takes place regularly, waste does not handle in time, which is a source of remarkable dirt. On the street of motorbikes, cars regularly travel, crush sand and sand The dust flies up. The air is hot, making dust a lot and longer. Flat city surface, many different low tall houses, also easy to create swirling winds, rolling dust. 4, in the city, motorbike, motorbike, production activities, wholesale activities Selling and entertainment creating many noise. The city does not have many strips of green trees bumbling noise, but only many builders, concrete, making sound waves bouncing, rebound, chaotic and more uncomfortable. 5, air city, most As industrial and transportation areas, often contain a lot of toxic gases such as oxide of sulfur, nitrogen, carbon, lead ... These substances have a negative impact on human health and environment causing The disease arises from air pollution. Do so, the city air is often worse than rural air, so there is no benefit of psychology and human health. Many countries around the world have been investing a lot of effort and money for researching finding solutions to overcome the situation of heavy environmental pollution in big cities. However, the problem has not been able to prize Right now. People living in cities, populous urban areas need to understand the disadvantages of the environment here, to take measures to protect and participate in the general environmental protection of the whole community.
