Most of the waste comes from buying certain things hat aren't excactly neede then wasting it. Usually the average American family doeasn't know that it ends up around some baby ducks neck in Guam.
Most heavy metals in household waste come from common household items like electronics, batteries, pesticides, cleaning products, and treated wood. These heavy metals can leach into the environment if not properly disposed of, posing risks to human health and ecosystems. Recycling and proper disposal of these items are important to prevent environmental contamination.
Some canned meat has been found to contain heavy metals. It can come from an unlined can. It can also come from a heavily contaminated body of water.
mostly from household sources but could someone please add to this because that's all i know
the heavy metals such as lead, zinc, cadmium, and arsenic from mining operations in Idaho's Coeur d'Alene region leached into groundwater. the the dissolved metals made their way into Idaho rivers and lakes. they eventually flowed into the Spokane river.
Easy answer you could have come up with by yourself I think. Crude oil, means oil straight from the ground and not refined yet. Heavy metals means not light metals. So not iron or sodium but Lead and other heavy stuff. Since oil comes from the ground and metals are mined from the ground, it makes sense that they could be found together. So if the teacher wants a different answer he should have said "how is crude oil formed" or something like that.
Yes, studies have shown that heavy metals such as lead, cadmium, and mercury can accumulate in arterial plaque. These metals can come from sources such as pollution, cigarette smoke, and contaminated food or water. Their presence in arterial plaque may contribute to inflammation and oxidative stress, potentially worsening cardiovascular health.
In a supernova explosion, heavy elements (metals) such as iron, nickel, gold, and uranium are created through nucleosynthesis. These elements are formed from the fusion of lighter elements under extreme temperature and pressure conditions during the explosive event.
They come into useful things from metals come i to use
Yes, metals do only come from ores and pure metals also are found in the Earth's crust.
Cations and anions are in ionic bond. They come from metals and non-metals.
Toxic waste can be released from industries, such as factories and chemical plants, where hazardous materials are used or produced. It can also come from agricultural practices, mining activities, and improper disposal of household chemicals. Additionally, natural sources like volcanic eruptions and wildfires can contribute to toxic waste release.
gold,silver,sterling silver are usually the metals they come in
