What Lead and mercury are two environmental pollutants why are they called heavy metals?
Lead and Mercury are called heavy metals because of their high atomic weights. They are considered environmental pollutants due to their toxic nature and ability to bioaccumulate in the environment. These heavy metals can have harmful effects on human health and the ecosystem.

What kind of pollutant are Arsenic cadmium lead and mercury?
Arsenic, cadmium, lead, and mercury are heavy metals that are considered toxic pollutants. They can accumulate in the environment and cause harm to human health and ecosystems when released into the air, water, or soil.
What effect does mercury have on gold?
Mercury can form an amalgam with gold, which is a mixture of the two metals. This can make it easier to extract gold from ore, but it can also lead to environmental pollution if not properly managed.
What harmful substances in the air water or soil called?
Harmful substances in the air, water, or soil are called pollutants. These pollutants can include chemicals, toxins, heavy metals, and other harmful substances that can negatively impact human health and the environment.
What toxins can absorb in hair?
Hair can absorb a variety of toxins, including heavy metals like lead and mercury, environmental pollutants such as cigarette smoke residue, drugs or medications, and even certain chemicals from hair products and dyes. These toxins can build up over time and may be detected through hair analysis.
What family element does mercury belong to?
Mercury belongs to the family of elements called transition metals. These elements are known for their variability in oxidation states and ability to form complex compounds. Mercury is specifically classified as one of the heavy transition metals due to its high density.
What are the causes of environmental hazards?
One of the causes of environmental hazard is heavy metals. However, light pollution, Mercury, and molds are also other environmental hazards.
What metals are attracted to Mercury?
Mercury is the only metal with mercury in it.
Four environmental pollutio and its pollutants?
Biological Decomposition of Environmental Pollutants-Biodegradable Pollutants such as plastic bags. Some of the most notable air pollutants are sulfur dioxide, nitrogen dioxide, carbon monoxide, ozone, volatile organic compounds (VOCs) and airborne particles, with radioactive pollutants probably among the most destructive ones (specifically when produced by nuclear explosions). Our Air Pollutants article provides a clear overview of sources and effects of these air pollutants. Water pollutants include insecticides and herbicides, food processing waste, pollutants from livestock operations, volatile organic compounds (VOCs), heavy metals, chemical waste and others. Some soil pollutants are: hydrocarbons, solvents and heavy metals.

What are some examples of toxic pollutants listed in the gizmo?
Some examples of toxic pollutants listed in the gizmo may include heavy metals like lead, mercury, and cadmium; organic pollutants like polychlorinated biphenyls (PCBs) and pesticides; as well as other harmful substances such as dioxins and solvents. These pollutants can have harmful effects on human health and the environment.
What are some of the general effects of air pollutants on the environment?
Acid deposition, pH in water decreases, increases amount of metals in soil: mercury, lead and aluminum.
What kind of pollutants are found in venice canals?
The pollutants found in Venice canals include organic waste and sewage, heavy metals, debris and litter, oils and greases, and pollutants from boat traffic. These pollutants can have negative effects on the water quality and the ecosystem of the canals. Measures are being taken to reduce these pollutants and protect the canals' environmental health.
What does rcra stand for?
It stands for the Resource Conservation and Recovery Act. It determined acceptable levels for certain metals in our environment, and was written back in 1976. It specifically monitors levels of 8 different metals that have special environmental concerns. Those metals, called the RCRA-8 metals, are arsenic, barium, cadmium, chromium, lead, mercury, selenium and silver.
What types of pollution is generated by gold mining?
Gold mining can generate a variety of pollutants, including mercury, cyanide, and heavy metals such as lead and arsenic. These pollutants can contaminate water sources, soil, and air, leading to environmental damage and potential health hazards for people living near mining sites. Efforts are made in the industry to mitigate these impacts through improved waste management and pollution control measures.
What effect does mercury have on gold?
Mercury can form an amalgam with gold, which is a mixture of the two metals. This can make it easier to extract gold from ore, but it can also lead to environmental pollution if not properly managed.
What kind of pollutant are Arsenic cadmium lead and mercury?
Arsenic, cadmium, lead, and mercury are heavy metals that are considered toxic pollutants. They can accumulate in the environment and cause harm to human health and ecosystems when released into the air, water, or soil.
