Summary

- EMF Standards in China: Stricter than Europe and America. Current standards include GB8702-88, GB9175-88, HJ/T 24-1998, with a new standard for wireless communication terminals expected in June 2006.
- EMF Research in China (1994-2004):
- Power Frequency EMF (50Hz):
- Epidemiological studies: Possible effects on immune, cardiovascular, and CNS functions. Complaints include memory loss, insomnia, and abnormal ECG. Exposure levels lower than China's standard but higher than some animal studies' effects.
- Animal and in vitro studies: Potential impacts on memory, brain neurotransmitters, and cell proliferation.
- Radio Frequency (RF):
- Possible disturbances to CNS, immune, and cardiovascular systems. Low-intensity RF might affect neurobehavior, cataract, and sperm development. Animal studies show impacts on learning, memory, and male reproduction.
- In vitro studies: RF might downregulate cytochrome oxidase activity and damage brain retention, potentially linked to Alzheimer's.
- Conclusion: Low-intensity EMF exposure below current limits may have adverse health effects. A precautionary approach is recommended when amending and prescribing new exposure limits.

Description

Chinese EMF exposure limits are stricter than European and American standards. Current Chinese EMF regulations include 'Hygienic standard for environmental electromagnetic waves' (GB8702-88), 'Regulations for electromagnetic radiation protection' (GB9175-88), and 'Technical regulations on environmental impact assessment of electromagnetic radiation produced by 500kV ultrahigh voltage transmission and transfer power engineering' (HJ/T 24-1998).
