Influencing factors:
Environmental factors affecting human health can be divided into three categories: physical factors (such as noise, vibration, radioactive substances, radio frequency radiation, etc. ); Chemical factors (such as toxic chemicals, heavy metals, pesticides, etc. ) and biological factors (such as bacteria, viruses, parasites, etc. ).
They can enter the air, water, soil and living environment through various channels, which is harmful to human health, among which chemical factors are the most important.
The impact of the environment on human health mainly includes the following three categories:
Biogeochemical diseases caused by the environment are health effects caused by the excess or lack of some trace elements in water and soil. It has been confirmed that there are cobalt, copper, nickel, boron, lead, fluorine, iodine, arsenic, zinc and other elements 10, among which iodine and fluorine are the most widely distributed, causing endemic fluorosis and endemic goiter.
② Acute and chronic damage of environmental pollution to human body. Some cause public hazards, some cause acute poisoning death to people in polluted areas, and some have a chronic impact on people's health, which increases people's sensitivity to certain diseases and increases the incidence and mortality of some common and frequently-occurring diseases among residents.
③ Long-term harm of environmental pollution to human health. It mainly includes carcinogenesis, mutagenicity and teratogenesis.
