LACW Local Authority Collected Waste (all waste collected by the local authority. This is a slightly broader concept than LACMW as it would include both this and non-municipal fractions such as construction and demolition waste) LAPC Local Air Pollution Control; LARAC Local Authority Recycling Advisory Committee; LAS Landfill Allowance Scheme
Air pollution can be chemical, physical or biological. [1] There are many different types of air pollutants, such as gases (including ozone, nitrogen oxides, sulfur dioxide, carbon monoxide, ammonia, and methane), particulates (such as soot), lead [2] and biological molecules.
Various definitions of pollution exist, which may or may not recognize certain types, such as noise pollution or greenhouse gases.The United States Environmental Protection Administration defines pollution as "Any substances in water, soil, or air that degrade the natural quality of the environment, offend the senses of sight, taste, or smell, or cause a health hazard.

Arsenic is a naturally occurring element and can be found in food, water, or air. There are also industrial sources of arsenic, including mining and smelting. [ 8 ] " People are exposed to elevated levels of inorganic arsenic through drinking contaminated water, using contaminated water in food preparation and irrigation of food crops ...
Municipal solid waste produces enormous amounts of methane, a potent greenhouse gas. [13] [14] However, nearly 90% of these methane emissions could be avoided with existing technologies. [14] [13] In particular, municipal solid waste can be used to generate energy because of the lipid content present within it.
A detailed inventory of greenhouse gas emissions from upstream oil and gas activities in Canada for the year 2000 estimated that fugitive equipment leaks had a global warming potential equivalent to the release of 17 million metric tonnes of carbon dioxide, or 12 percent of all greenhouse gases emitted by the sector, [9] while another report put fugitive emissions at 5.2% of world greenhouse ...
A pollutant or novel entity [1] is a substance or energy introduced into the environment that has undesired effect, or adversely affects the usefulness of a resource. These can be both naturally forming (i.e. minerals or extracted compounds like oil) or anthropogenic in origin (i.e. manufactured materials or byproducts).
