Do you know what aspects of environmental problems are? Write at least three words about the harm these environmental problems will bring.

Air pollutants do harm to human body in many ways, such as respiratory system damage, physiological dysfunction, digestive system disorder, nervous system abnormality, mental decline, cancer, disability and so on. People call the smoke of this disaster "the smoke of killing". When the concentration of pollutants in the atmosphere is high, it will cause acute pollution poisoning, or aggravate the symptoms, and even kill thousands of people within a few days.

2. Harm to plants:

When the concentration of pollutants is high, it will cause acute damage to plants, damage to the surface of plant leaves, or directly cause leaves to wither and fall off; When the concentration of pollutants is not high, it will cause chronic damage to plants, make the leaves of plants fade, or have no harmful symptoms on the surface, but the physiological functions of plants are affected, leading to the decline of plant yield and deterioration of quality.

3. Harm to weather and climate:

Reduce the amount of solar radiation reaching the ground: A large number of smoke particles discharged into the atmosphere by factories, power stations, automobiles and household heating equipment make the air very turbid, which blocks the sunlight and reduces the amount of solar radiation reaching the ground.

Extended data

Pollution sources mainly include:

1. Waste smoke, waste gas, noise, dirty water and garbage discharged in people's lives.

2. Exhaust gas and noise emitted by vehicles (all fuel vehicles, ships, airplanes, etc.). ).

3, a large number of chemical substances such as fertilizers, pesticides and herbicides are used for the water flowing out after farmland irrigation.

4. Mine wastewater and waste residue.

5, machine noise, electromagnetic radiation, carbon dioxide pollution, etc.

Where are the difficulties in the prevention and control of ozone pollution?

Ozone usually exists in the upper atmosphere about 30 kilometers from the ground, which can effectively block ultraviolet rays and protect human health. The so-called ozone pollution can never be separated from photochemical smog. Daily ozone pollution actually refers to photochemical smog. From the actual situation, the ozone content in the air is one order of magnitude lower than other components, so the scientific research on ozone pollution is still insufficient. The precursors of ozone are mainly nitrogen oxides and volatile organic pollutants, and also the precursors of secondary fine particles. Volatile organic compounds can have a series of photochemical chain reactions with nitrogen oxides under the irradiation of ultraviolet light, which can improve the oxidation of the atmosphere, increase the ozone concentration on the surface and accelerate the formation of secondary fine particles. First, first, ozone ...
