Chromium is a toxic heavy metal commonly found in modern tannery industries due to its use in leather tanning processes. It can pose environmental and health risks if not properly managed and treated.
Why are the usual coinage metals chosen over more active metals for use in coins?
Metals are exposed to the atmosphere and corrosive environments such as the sweat on the palms of hands. As coins are designed to be around for a long time (unlike banknotes) the metals they are made from need to be a of very low reactivity so they do not corrode.
Can fertilisers come under toxic chemicals?
Yes, some fertilisers can contain toxic chemicals such as heavy metals or synthetic compounds that can be harmful to the environment and human health if not used properly or if they leach into water sources. It is important to follow proper guidelines for their use and disposal.
What is something that gets into water that is not supposed to be there?
There are many things that can get into water that are not supposed to be there. These can range from agricultural runoff, which can contain pesticides and fertilizers, to industrial pollutants like heavy metals that are released into the environment. The presence of these contaminants can make water unsafe for consumption or recreational use. Additionally, untreated sewage can also enter bodies of water and contaminate them with bacteria and other harmful substances. It is essential to protect our water sources from these pollutants, as clean water is essential for a healthy environment and human life.
Why are electromagnets used for picking up heavy metals?
Well electromagnets have great power so it is understandable that someone would use it to pick up heavy metals.
What is eco-friendly technology?
Eco-friendly means that creating and/or using the technology does not have a bad effect on the environment, or that it is friendlier than other similar technologies. Implications on the environment can be: use of energy that endangers the environment (e.g global warming); adds pollution; endangers human or animal life and more...
How can one test water for heavy metals effectively?
To test water for heavy metals effectively, one can use specialized testing kits or send samples to a certified laboratory for analysis. These methods can detect a wide range of heavy metals, providing accurate results for ensuring water safety.
Why is silver heavy?
Certain groups of people try to classify silver as a heavy metal such as cadmium and mercury, in order to promote fear mongering regarding the use of silver in medicine. The term "heavy metals" is both meaningless and misleading. Just about anything can be toxic if used abusively. In truth, silver, gold, copper and platinum are noble metals, not "heavy metals" like mercury, plutonium or lead. If you look it up in the Wikipedia encyclopedia, it is not found in the list of heavy metals.
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.

Few people need any heavy metals removed from their body. If you think you have a problem, you should consult your physician. You should not use anything not prescribed by him or her.
What heavy metals that can be taken up by plants?
The metals having density more than 5 are usually known as heavy metals. Density of some heavy metals is as below: Zinc (Zn) 7.13 Iron (Fe) 7.87 Copper (Cu) 8.96 Silver (Ag) 10.49 Lead (Pb) 11.36 Mercury (Hg) 13.55 We use fertilizers which contain elements having density more 5 or more than 5 like zinc sulphate or copper sulphate ets. so we can say that plants take these heavy metals in shape of fertilizers.
Why do they use aluminum in a mobile phone?
Well, aluminum is not very heavy compared to other metals, and it is easy to produce. That's the non-scientific answer.
Which would be least likely to pollute water with heavy metals?
Agricultural runoff from organic farms is least likely to pollute water with heavy metals compared to other sources such as industrial activities or mining. Organic farming practices typically minimize the use of synthetic chemicals and heavy metal-containing fertilizers, reducing the risk of contamination.
What is the different between heavy metal and trace metal?
Soft metal is more like just soft rock but heavy metal is like scremos and other REALLY HEAVY metal and black metal is REALLY REALLY HEAVY like they use death guturals and they are the hardest to understand.
