Open Burning Of Waste
The open burning of waste is a disposal method of waste or garbage. It is a disposal method used globally, but often used in low and middle-income countries that lack adequate waste disposal infrastructure. Numerous governments and institutions have identified the open burning of waste as a major contributor to greenhouse gas emissions. It also poses health risks with the cocktail of air pollutants often created when waste is burned in an open air environment. At COP26 open waste burning was raised as a major contributor to climate change. It produces a wide range of atmospheric pollutants including short lived climate pollutants (SLCPs), such as black carbon (BC). BC emissions are a major source of fine particulate matter, with a climate change impact up to 5,000 greater than . Background The United Nations has raised concerns about the amount of black carbon and methane produced from open burning as a method of waste disposal. Many cities and regions suffer with air pollution an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Garbage
Garbage, trash (American English), rubbish (British English), or refuse is waste material that is discarded by humans, usually due to a perceived lack of utility. The term generally does not encompass bodily waste products, purely liquid or gaseous wastes, or toxic waste products. Garbage is commonly sorted and classified into kinds of material suitable for specific kinds of disposal. Terminology The word ''garbage'' originally meant chicken giblets and other entrails, as can be seen in the 15th century Boke of Kokery, which has a recipe for ''Garbage''. What constitutes garbage is highly subjective, with some individuals or societies tending to discard things that others find useful or restorable. The words garbage, refuse, rubbish, trash, and waste are generally treated as interchangeable when used to describe "substances or objects which the holder discards or intends or is required to discard". Some of these terms have historic distinctions that are no longer present. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Mercury (element)
Mercury is a chemical element; it has Symbol (chemistry), symbol Hg and atomic number 80. It is commonly known as quicksilver. A Heavy metal element, heavy, silvery d-block element, mercury is the only metallic element that is known to be liquid at standard temperature and pressure; the only other element that is liquid under these conditions is the halogen bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature. Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). The red pigment vermilion is obtained by Mill (grinding), grinding natural cinnabar or synthetic mercuric sulfide. Exposure to mercury and mercury-containing organic compounds is toxic to the nervous system, immune system and kidneys of humans and other animals; mercury poisoning can result from exposure to water-soluble forms of mercury (such as mercuric chloride or methylmercury) either directly or through mechanisms of biomagnification.

Soot
Soot ( ) is a mass of impure carbon particles resulting from the incomplete combustion of hydrocarbons. Soot is considered a hazardous substance with carcinogenic properties. Most broadly, the term includes all the particulate matter produced by this process, including black carbon and residual pyrolysed fuel particles such as coal, cenospheres, charred wood, and petroleum coke classified as cokes or char. It can include polycyclic aromatic hydrocarbons and heavy metals like mercury. Soot causes various types of cancer and lung disease. Terminology Definition Among scientists, exact definitions for soot vary, depending partly on their field. For example, atmospheric scientists may use a different definition compared to toxicologists. Soot's definition can also vary across time, and from paper to paper even among scientists in the same field. A common feature of the definitions is that soot is composed largely of carbon based particles resulting from the incomplete burni ...

Canadian Government
The Government of Canada (), formally His Majesty's Government (), is the body responsible for the federal administration of Canada. The term ''Government of Canada'' refers specifically to the executive, which includes ministers of the Crown (together in the Cabinet) and the federal civil service (whom the Cabinet direct); it is corporately branded as the ''Government of Canada''. There are over 100 departments and agencies, as well as over 300,000 persons employed in the Government of Canada. These institutions carry out the programs and enforce the laws established by the Parliament of Canada. The federal government's organization and structure was established at Confederation, through the ''Constitution Act, 1867'', wherein the Canadian Crown acts as the core, or "the most basic building block", of its Westminster-style parliamentary democracy.

Polychlorinated Biphenyl
Polychlorinated biphenyls (PCBs) are organochlorine compounds with the formula Carbon, C12Hydrogen, H10−''x''Chloride, Cl''x''; they were once widely used in the manufacture of carbonless copy paper, as heat transfer fluids, and as dielectric and coolant fluids for electrical equipment. They are highly toxic and carcinogenic chemical compounds, formerly used in industrial and consumer electronic products, whose production was banned internationally by the Stockholm Convention on Persistent Organic Pollutants in 2001. Because of their longevity, PCBs are still widely in use, even though their manufacture has declined drastically since the 1960s, when a multitude of problems was identified. With the discovery of PCBs' environmental toxicity, and classification as persistent organic pollutants, their production was banned for most uses by United States federal law on January 1, 1978. The International Agency for Research on Cancer (IARC) rendered PCBs as definite carcinogens i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Dioxins And Dioxin-like Compounds
Dioxins and dioxin-like compounds (DLCs) are a group of chemical compounds that are persistent organic pollutants (POPs) in the environmental pollutant, environment. They are mostly by-products of burning or various industrial processes or, in the case of dioxin-like polychlorinated biphenyl, PCBs and polybrominated biphenyl, PBBs, unwanted minor components of intentionally produced mixtures. Some of them are highly toxic, but the toxicity among them varies 30,000-fold. They are grouped together because their mechanism of action is the same. They activate the aryl hydrocarbon receptor (AH receptor), albeit with very different binding affinities, leading to high differences in toxicity and other effects. They include: * Polychlorinated dibenzodioxins, Polychlorinated dibenzo''-p-''dioxins (PCDDs), or simply dioxins. PCDDs are derivatives of dibenzodioxin, dibenzo''-p-''dioxin. There are 75 PCDD congener (chemistry), congeners, differing in the number and location of chlorine atoms, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Sulphur Oxide
Sulfur oxide Sulfur oxides (SOx) are a group of chemical compounds formed by the combination of sulfur and oxygen. The most common SOx are sulfur dioxide (SO2) and sulfur trioxide (SO3). SOx are produced naturally through volcanic activity and are also released into the atmosphere from human activities like burning fossil fuels and industrial processes. Sulfur oxide (SO''x'') refers to one or more of the following: * Lower sulfur oxides (S''n''O, S7O2 and S6O2) * Sulfur monoxide (SO) and its dimer, Disulfur dioxide (S2O2) * Sulfur dioxide (SO2) * Sulfur trioxide (SO3) * Higher sulfur oxides (SO3 and SO4 and polymeric condensates of them) * Disulfur monoxide Disulfur monoxide or sulfur suboxide is an inorganic compound with the formula S2O, one of the lower sulfur oxides.
