Most heavy metals, but not all, are not even required by human body and they cause problems even in a very small concentration. They often take same pathways as essential nutrients and so cause toxic effects. They also bioaccumulate and biomagnify

What is the difference between heavy metals and the other metals?
Scientifically speaking, there are a couple of fundamental differences between heavy metals and other metals in the table of the elements. Heavier metals tend to have more ions and typically, less toxic elements.
Can the body leach heavy metals?
Not easily. The molecular size of heavy metals means the kidneys struggle to excrete them. Most heavy metals are stored in hair, finger nails and other body tissues. Many, such as copper, lead, iron, are toxic if ingested in large amounts.
Can heavy metals pass through the placental barrier?
Most probably they will pass that way. They are toxic to the mother and foetus as well.
What kind of pollutant are Arsenic cadmium lead and mercury?
Cadmium, lead, and mercury are toxic heavy metals; arsenic is a toxic semi-metal. All of these are extremely dangerous to human health.
Is the element hassium hazardous?
There have only been about 100 atoms of Hassium created, and the half life of the element is extremely short- so we do not know for sure. It is radioactive, and we expect it to act like other heavy metals, which are toxic.
What are the importance of heavy metals in cooking?
Heavy metals compounds have frequently toxic properties.
What is heavy metal poisoning?
Heavy metal poisoning is the toxic accumulation of heavy metals in the soft tissues of the body.
What of the toxic heavy metals is found in modern tannery industries?
Chromium
What effects do heavy metals have on human bodies?
The heavy metals like lead and mercury are toxic to our human bodies as the body system has no means of getting rid of them.
What is the difference between heavy metals and the other metals?

What is impact of effluents from cement factory on groundwater?
The effluents from cement factories is highly toxic, and contains high levels of heavy metals. Both plant life and water near cement factories were found to have increased levels of heavy metals as well as other damage.
Why there is need to assess the heavy metal pollution in water?
Because many heavy metals - and also another impurities - are toxic and dangerous for the health.
Can the body leach heavy metals?
Not easily. The molecular size of heavy metals means the kidneys struggle to excrete them. Most heavy metals are stored in hair, finger nails and other body tissues. Many, such as copper, lead, iron, are toxic if ingested in large amounts.
What is the role of humifulvate in detoxifying the plants from heavy metals?
Humifulvate removes heavy metals from plants. The detoxification process occurs when Humifulvate attaches to the toxic Mercury, Lead, Aluminum, or Cadmium and takes them out of the plants system.
Is steel a heavy metal?
Steel is an alloy consisting mainly of iron, which is metal, but not heavy metal. Heavy metal means toxic metals like mercury, lead, plutonium and uranium
If heavy metals are injurious to the central nervous system why are eating utensils made of metal and do they have any deleterious affect?
I don't think stainless steel is a heavy metal. You kind of answered your own question by referring to both 'heavy metals' and 'metal.' They are not the same thing. While 'heavy metals' are metal, not all metals are 'heavy metals.' 'Heavy metals' refer to metallic chemical elements that have relatively high density and are poisonous at low concentrations. Examples of heavy metals would be mercury, cadmium, chromium, thallium, and lead. And from the US department for Labor: "Toxic metals, including 'heavy metals,' are individual metals and metal compounds that negatively affect people's health. Some toxic, semi-metallic elements, including arsenic and selenium, are discussed in this page. In very small amounts, many of these metals are necessary to support life. However, in larger amounts, they become toxic. They may build up in biological systems and become a significant health hazard." The metals that we use in our everyday lives, such as in spoons, do not contain enough poisonous metals to accumulate in our body enough to do harm. And the main metals in our utensils are not at all harmful. Note: whilst cast iron and stainless steel are actually beneficial to health, some people are concerned about the use of aluminium in pans. It's not a heavy metal, nor are deleterious effects in the small quantities caused by cookware proven, but some people only use coated aluminium as a precaution. More dangerous are copper pans which should always have an inert lining.
Can heavy metals pass through the placental barrier?
Most probably they will pass that way. They are toxic to the mother and foetus as well.
