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.
Heavy Metals
Lead, mercury, and arsenic.
Mercury, lead, and many other heavy metals.
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.
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.
Heavy metals like mercury (Hg) and Lead (Pb)
This is because heavy metals are those metals having a neutron is to proton ration equal to or greater than 1.5Lead has 82 protons and 125 neutronsn/p=125/82=1.52Mercury has 80 protons and 121 neutronsn/p=121/80=1.51Hence lead and mercury are heavy metals
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.
Poisoning and disease can occur due to human exposure to trace quantities of heavy metals. Common trace metals include mercury (Hg), arsenic (Ar) and lead (Pb).
Cadmium, lead, and mercury are toxic heavy metals; arsenic is a toxic semi-metal. All of these are extremely dangerous to human health.
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
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.
