Environment and health are closely linked. Do you know the facts?

1. Soil pollution affects soil function and effective utilization, and harms public health.

The main sources of soil pollution are agricultural materials (fertilizer, pesticide, plastic film, etc.), industrial wastes (wastewater, solid waste, exhaust gas, etc.) and municipal solid waste (sewage, solid waste, smoke/ tail gas, etc.).

What should we do? For contaminated construction land, we should carry out remediation or barrier projects and implement institutional controls. For contaminated agricultural land, we should adjust the pH level, regulate water content, return farmland to forest, and plant cotton, hemp, mulberry, bamboo, flowers and seedlings.

 

2. Clean water environment and safe drinking water are the foundation of public health.

Say NO to water pollution: industrial wastewater, urban sewage, pesticides, fertilizers, and others.

 

3. Air pollution will cause adverse effects on respiratory system and cardiovascular system.

Air provides the basis for human respiration. An adult typically breathes more than 20,000 times a day, requiring the intake of 10 to 15 cubic meters of air.

 

4. Marine pollution endangers the safety of marine products and affects the marine ecosystem and human health.

The high ammonia phosphorus sewage into the sea causes the red tide; the red tide produces red tide toxin, which pollutes the seafood; the plastic breaks and adsorbs the pollutants, which are eaten by the marine life; the human catches a large number of seafood to meet the food and nutrition needs.

 

5. Protecting biodiversity and maintaining ecological balance is beneficial to human health and sustainable development.

Crops rely on insects for pollination, and the risk to food security increases as the diversity and numbers of wild insects decline; and forests and natural habitats are degraded, disturbed and destroyed by population growth, land expansion and other factors.

 

6. The negative impact of climate change on the ecological environment increases health risks.

The frequency and intensity of extreme weather events caused by climate change are increasing, resulting in a series of chain consequences, such as heat waves, rainstorms, floods and droughts, drinking water shortages, forest fires, etc., which have directly affected human life and health.

 

7. Radiation is everywhere, but there is no need to be afraid of it.

We are exposed to natural radiation every day, and the total amount of natural radiation we receive is far greater than that from human activities such as nuclear energy and nuclear technology. The radiation dose people may encounter in daily life is far lower than the dose harmful to the human body.

Under the condition of safe operation, nuclear energy is a kind of clean energy with minimal impact on the environment. The radiation dose produced by nuclear power plant during normal operation is far below the national standard, and will not harm human health.

 

8. Properly sorting and disposing of household waste not only protects the environment but also benefits public health.

If the large amount of domestic waste is not treated and disposed of in time, it will not only produce foul smell, breed mosquitoes and flies, affect the surrounding environment, but also pollute the soil, surface water and groundwater, air, and affect the public health.

 

9. Improper use or disposal of toxic and hazardous substances in work and life can pose potential health risks.

Household chemicals should be kept out of food and water and out of reach of children.

 

10. Noise pollution disrupts daily life and harms health.

Different sound intensity has different effect on human, the larger noise can cause temporary or permanent hearing damage.
