They tend to be poisonous to humans and can contaminate water and soil. Heavy metals would include elements such as lead, Mercury, tin, arsenic, and antimony.
The disadvantage is that you can't destroy heavy metals (or any metals or, indeed, any chemical elements) by incineration. So the most you can achieve by incineration is scattering heavy metals around with ash that is carried away with smoke.
I am sodium because I am a metal and metals are heavy and i am also very expensive.
No, arsenic is a metalloid, which means it has characteristics of both metals and non-metals.
All of the transition state elements are relatively heavy. The light metals, such as beryllium, lithium etc., are not transition state metals.
My best guess...cilantro.
No. These are not heavy metals. They are salts of non heavy metals.
Heavy metals are typically found in the middle of the periodic table. These heavy metals are often also transition metals.
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.
Heavy metals compounds have frequently toxic properties.
It can have small amounts of heavy metals, depends where it comes from. - If you are concerned take a sample for lab analysis.It can have heavy metals, depends where it comes from. If you are concerned take a sample for lab analysis.
they are considered heavy metals because of the weight to volume ration in comparison to other metals. they have more mass with little volume than other metals do.
Depends on where the sludge has come from. The sludge left behind in sewerage treatment contains heavy metals. These can get into fish, which are then caught and consumed by humans. Heavy metals accumulate and can cause severe illness and deformatity in unborn children and affect health of adults.
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.

Lumber mills are least likely to pollute water with heavy metals. Did you know that Zinc, copper, and lead are three of the most common heavy metals released from road travel.
Common heavy metals that can cause heavy metal poisoning include lead, mercury, arsenic, cadmium, and chromium. These metals can accumulate in the body over time and lead to various health problems, including damage to the brain, kidneys, liver, and other organs. Exposure to heavy metals can occur from sources such as contaminated water, air pollution, certain foods, and occupational hazards.
