Physical pollution includes: noise pollution, light pollution, thermal pollution, electromagnetic radiation, radioactive pollution, vibration pollution.
1, noise pollution
The noise caused by industrial activities, transportation and building construction exceeds the level tolerated by the environment, and adversely affects human health and the ecosystem.
2. Light Pollution
Over-illumination in cities and industrial areas, neon lights, headlights, and light emissions from industrial and commercial equipment at night interfere with animal clocks, human routines, and astronomical observations and ecosystems.
3. Thermal pollution
Increased ambient temperatures caused by energy production and consumption, such as waste heat from power plants and factories, and the heat island effect in urban buildings and densely populated areas.
4, Electromagnetic Radiation
Electromagnetic radiation generated by sources of electromagnetic radiation such as power lines, radio waves, microwaves, radar, and television, which may have a negative impact on human health and the ecosystem.
5. Radioactive pollution
Release of radioactive substances caused by nuclear energy accidents, industrial radioactive sources and medical equipment can be harmful to the environment and human body.
6, vibration pollution
Construction, excavation, explosions and transportation vibrations can cause vibration of the ground and structures, causing damage to the surrounding environment and buildings.
Three suggestions for the prevention of physical pollution
1. Suspended substance pollution prevention
Strengthen the monitoring of water quality to ensure that the content of suspended substances is within the standards, strengthen the treatment of wastewater to ensure that the wastewater is effectively treated to reduce the content of suspended substances prior to discharge, and strengthen the management of solid waste to prevent the waste from into the water body, affecting water quality.
2, thermal pollution prevention
Adopting effective cooling technology to reduce cooling water emissions; heat recovery and utilization of discharged cooling water to reduce the waste of energy; strengthening wastewater treatment to ensure that wastewater is effectively treated before discharge to reduce the impact of thermal pollution.
3, radioactive pollution prevention
Strengthen the management of radioactive substances, to avoid radioactive substances into the water body; strengthen the treatment of radioactive wastewater, to ensure that the wastewater is effectively treated before discharge, to reduce the impact of radioactive contamination; and strengthen the treatment of radioactive wastes, to avoid radioactive wastes into the environment.
