Summary
Static electric and magnetic fields up to 8 T show no acute adverse health effects beyond transient symptoms like vertigo. Long-term exposure data is limited, but no chronic effects have been reported.
Area of Science:
- Environmental Health
- Electromagnetism
- Public Health
Background:
- The World Health Organization (WHO) International EMF Project released a monograph on static electric and magnetic fields.
- Understanding the biological and health impacts of static electromagnetic fields is crucial for public safety.
Purpose of the Study:
- To provide an overview of the biological and health effects of static electric and magnetic fields as discussed in the WHO monograph.
- To evaluate current scientific knowledge regarding static field exposure guidelines.
Main Methods:
- Review of the WHO Environmental Health Criteria monograph on static electric and magnetic fields.
- Analysis of reported biological and health effects from static magnetic field exposure.
Main Results:
- No acute adverse health effects observed at static magnetic flux densities up to 8 T, apart from transient phenomena like vertigo and nausea.
- Limited data exists on long-term or chronic effects of prolonged static magnetic field exposure.
- Current scientific understanding was used to discuss the 1994 International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines.
Conclusions:
- Static magnetic fields up to 8 T do not appear to cause significant acute health issues.
- Further research is needed to fully assess the long-term health implications of static magnetic field exposure.
- Existing guidelines for static field exposure require ongoing evaluation in light of emerging scientific evidence.

02:59Biological Effects of Radiation
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they produce ions...
01:23Toxicity Testing in Animals
Toxicity tests in animals are grounded on two main assumptions: first, the effects observed in laboratory animals can be extrapolated to humans, especially when adjusted for body surface area; second, high-dose exposure in animals is essential to identify potential human hazards from lower doses. This is based on the quantal dose-response concept, which faces the challenge of extrapolating results from relatively few test animals to much larger human populations. For example, a 0.01% incidence...
01:26Toxic Reactions: Overview
When toxic substances penetrate the human body, they disseminate to various tissues, undergoing metabolic changes. This process yields reactive metabolites that may covalently bind with specific target molecules, resulting in toxicity.
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...

01:27Effects of Chemicals: Overview
Drugs, encompassing various chemical compounds from natural sources, lab synthesis, or genetic engineering, elicit different biological responses in living organisms. Some of these responses are desirable or therapeutic, while others are undesirable. The primary goal of administering a drug is to achieve a therapeutic effect, that is, to address a specific disease or health condition. Any concurrent effects outside of this therapeutic outcome are considered undesirable. These undesirable...
01:36Types of Toxins
Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.

01:24Drug Toxicity: Dose-Dependent Reactions
Drug toxicities can be stratified into pharmacological, pathological, or genotoxic based on their mechanisms. The incidence and severity of these toxicities generally increase with the drug's concentration in the body and exposure time.Pharmacological toxicity is evident when the therapeutic effects of drugs overshoot into adverse reactions in a predictable, dose-dependent manner. Central nervous system (CNS) depression from barbiturates is a classic example, with effects escalating from...
