Handbook on the Toxicology of Metals
The 2015 Handbook on the Toxicology of Metals, Fourth Edition, bridges the gap between established knowledge and new advances in metal toxicology, with new chapters on toxic metals in food, toxicity of metals released from medical devices, gene-environment interactions, neurotoxicology of metals, and cardiotoxicology of metals.
What causes heavy metal contamination?
Lead, mercury, arsenic, and cadmium are the heavy metals most commonly associated with human poisoning. Heavy metal poisoning can occur as a result of industrial exposure, air or water pollution, foods, medicines, improperly coated food containers, or ingestion of lead-based paints.
What effects do metals have?
Heavy metal toxicity can have acute or chronic effects, and long-term exposure to the metal can cause degenerative muscular, physical, and neurological processes that are similar to diseases like Parkinson’s disease, multiple sclerosis, muscular dystrophy, and Alzheimer’s disease.
What environmental factors affect metal toxicity?
Many environmental factors, including alkalinity, hardness, pH, dissolved oxygen, temperature, turbidity, carbon dioxide, magnesium salts, phosphates, and chelating agents, can affect heavy metal toxicity in aquatic organisms (National Research Council, 1972).
What is the effect of heavy metals on the environment?
Heavy metals contaminate natural water bodies, sediments, and soils after being released from both natural and anthropogenic sources. Heavy metals released into the atmosphere in volcanic eruptions and various industrial emissions eventually return to the land and cause contamination of waters and soils.
What are the symptoms of heavy metals in the body?
Signs and Symptoms
- Heart abnormalities such as cardiomyopathy or abnormal heart beat (dysrhythmia)
- Nervous system symptoms (e.g. numbness, tingling of hands and feet, and weakness)
- Abdominal pain, nausea, vomiting, and diarrhea (the hallmark symptoms of most cases of acute metal ingestion)
What are the common symptoms of heavy metal contamination in the body?
What are the signs and symptoms of heavy metal intoxication?
- Abdominal pain.
- Shortness of breath.
- Tingling in your hands and feet.
What is the most toxic heavy metal?
Mercury poisoning is known as acrodynia or pink disease, and it is the most toxic heavy metal in the environment.
Which metal causes harmful effects?
Arsenic, cadmium, chromium, lead, and mercury are among the priority metals of public health concern because of their high toxicity; these metallic elements are considered systemic toxicants that can cause multiple organ damage even at low levels of exposure.
How can we prevent metal pollution?
Bioremediation is a cutting-edge technique for removing and recovering heavy metal ions from polluted areas. It involves using living organisms to reduce and/or recover heavy metal pollutants into less hazardous forms, such as algae, bacteria, fungi, or plants.
How long do heavy metals stay in the body?
Heavy metal chelation with cilantro and chlorella can naturally remove 87% of lead, 91% of mercury, and 74% of aluminum from the body in 45 days, according to various studies.
How do you manage heavy metals?
Many physical, chemical, and biological treatment options have been proposed in recent years to remediate heavy metal contaminated soil, water, and sediments, including thermal treatment, adsorption, chlorination, chemical extraction, ion-exchange, membrane separation, electrokinetics, and bioleaching.
How do you fix heavy metal pollution?
Excavation (physical removal of the contaminated material), stabilization of the metals in the soil on site, and the use of growing plants to stop the spread of contamination or to ex- tract it are some of the cleanup (or remediation) technologies available for reducing the harmful effects at heavy metal-contaminated sites.
Can heavy metals be removed from the body?
A heavy metal detox aims to remove excess heavy metals from the body using a substance called a chelator and a process called chelation to transport them out of the body. A heavy metal detox may also be referred to as chelation therapy.
What is the heaviest metal?
