Environmental pollutants are harmful to human health in many ways. First of all, pollutants exposed to the air, such as particulate matter, sulfur dioxide and nitrogen dioxide, will enter the human body through the respiratory system, increasing the risk of respiratory diseases, such as asthma, chronic obstructive pulmonary disease and lung cancer. Secondly, pollutants in water, such as heavy metals, organic chemicals and pathogens, can enter the human body through drinking water and food chain, causing health problems such as water-borne diseases, poisoning and cancer. In addition, pollutants in the soil may also enter the human body through crops and direct contact with the soil, causing potential harm to human health.
To sum up:
The harm of environmental pollutants to human health can not be ignored. Air, water and soil pollution may have negative effects on human health, including respiratory diseases, water-borne diseases, poisoning and cancer. In order to protect human health, effective environmental protection measures must be taken to reduce the emission and exposure level of pollutants.
Legal basis:
1. Article 33 of the Environmental Protection Law of People's Republic of China (PRC) stipulates: "The state establishes an environmental quality monitoring system to monitor environmental factors such as air, water and soil, and timely disclose environmental quality information."
2. Article 5 of the Law on the Prevention and Control of Air Pollution in People's Republic of China (PRC) stipulates: "The State shall take measures to prevent and reduce air pollution, protect and improve the atmospheric environment, and safeguard public health."
3. Article 3 of the Law on Prevention and Control of Water Pollution in People's Republic of China (PRC) stipulates: "The State shall take measures to protect water resources, prevent and control water pollution, improve the water environment, ensure the safety of drinking water and maintain ecological balance."
Article 7 of the Law on the Prevention and Control of Soil Pollution in People's Republic of China (PRC) stipulates: "The state strengthens the prevention and control of soil pollution, protects and improves the soil environment, and guarantees the quality of agricultural products and public health."
The above legal basis emphasizes the responsibility and goal of the state in environmental protection, aiming at promoting environmental protection and reducing the harm of environmental pollutants to human health through legal means.
