This is not a correct term; probably you think to compounds with a big molecular mass.
Actually word Heavy Chemicals use in a broad sense it means the chemicals that are widely used in a country or in a territory. Also the product of chemical industries that are raw material of other industries are called heavy chemicals.
Heavy. And I believe that the corporate name actually is "Pfizer Pharmaceuticals.
No. Heavy water refers to water formed with a majority of the heavier isotopes of hydrogen, which are very radioactive; this water can be used to transport such isotopes more easily. Cells use many different chemicals to get their energy, but water is a product of the process, not an "ingredient".
Some common toxic chemicals found in copy paper include bleach (used in the whitening process), volatile organic compounds (VOCs) emitted during production, and heavy metals and bisphenol-A (BPA) in the ink. These chemicals can pose health risks if exposure levels are high.
Catalase can be inhibited by certain chemicals like cyanide, azide, and heavy metals, as well as by extreme pH levels. Competitive inhibitors that bind to the active site of catalase can also hinder its function.

I would say, that which is sourced from a heavy pest spraying area; full of toxic chemicals!
"Chemicals, heavy metals, parasites, fungi, viruses and bacteria can cause food borne illness."
Cigarette smoke contains over 7,000 chemicals, including at least 250 known to be harmful and more than 60 that can cause cancer. These chemicals include nicotine, tar, carbon monoxide, formaldehyde, ammonia, and various heavy metals.
Lead is considered a heavy metal. It bonds to many chemicals in the organic system of animals and prevents them from working properly.
hydrogen and oxygen, same as ordinary water except the hydrogen is twice the mass of ordinary hydrogen and we call it deuterium.
Factories release various chemicals into the environment through their manufacturing processes. These chemicals can include pollutants such as carbon dioxide, sulfur dioxide, nitrogen oxides, heavy metals, and volatile organic compounds, which can have negative impacts on air, water, and soil quality as well as human health. Regulations and monitoring are in place to control and minimize the release of these chemicals from factories.
"Heavy Water" still has the formula H2O, but the hydrogen in the water has a neutron as well as a proton- much like Helium does. It still has it's one electron however. Heavy water is used in NMR as a solvent for organic chemicals in proton NMR- to avoid interference on the spectra.
Cyprus's main imports include oil, chemicals, heavy machinery, clothing, electrical goods, vehicles, clothing and steel.
Chemicals can be harmful to both humans and the environment, depending on their type, concentration, and exposure levels. Some chemicals, like heavy metals and certain pesticides, can lead to health issues such as respiratory problems, cancer, and endocrine disruption. Additionally, chemicals can contaminate soil and water, harming ecosystems and wildlife. However, not all chemicals are harmful; many are essential for everyday life and can be used safely with proper regulations and practices.
From the polluting elements, which can consist of germs, fungi, algae, heavy metals, chemicals, and other harmful matter.
