A team of researchers at the University of East Anglia analysed unpolluted air samples from Tasmania dating from the period 1978 to 2012. They concluded that the CFCs [which?] they studied had started entering the atmosphere from anthropogenic sources in the 1960s and that while the abundance of certain CFCs had decreased, owing to the Montreal Protocol, the abundance of CFC-113a in the ...
Other common formulations include granules (GR) and dusts (DP), although for improved safety the latter have been replaced by microgranules (MG e.g. for rice farmers in Japan). Specialist formulations are available for ultra-low volume spraying, fogging, fumigation, etc. Very occasionally, some pesticides (e.g.
CFC-113 was one of the most heavily produced CFCs. In 1989, an estimated 250,000 tons were produced. [5] It has been used as a cleaning agent for electrical and electronic components. [12] CFC-113’s low flammability and low toxicity made it ideal for use as a cleaner for delicate electrical equipment, fabrics, and metals.
Class 3: Flammable Liquids A flammable liquid is a liquid having a flash point of not more than 60 °C (140 °F), or any material in a liquid phase with a flash point at or above 37.8 °C (100 °F) that is intentionally heated and offered for transportation or transported at or above its flash point in a bulk packaging. The following exceptions ...
These include chlorofluorocarbons and hydrofluorocarbons, both of which cause ozone depletion (although the latter much less so) and contribute to global warming. 'Freon' is the brand name for the refrigerants R-12 , R-13B1 , R-22 , R-410A , R-502, and R-503 manufactured by The Chemours Company, and so is not used to label all refrigerants of ...
Downtown Kansas City is defined as being roughly bounded by the Missouri River to the north, 31st Street to the south, Troost Avenue to the east, and State Line Road to the west. The locations of National Register properties and districts are in an online map.
After several drafting amendments, Section 113 took its present form: All fermented, distilled, or other intoxicating liquids passing into any State or remaining therein for use, consumption, sale, or storage, shall be subject to the laws of the State as if such liquids had been produced in the State.
Other metal alloys that are liquid at room temperature include galinstan, which is a gallium-indium-tin alloy that melts at −19 °C (−2 °F), as well as some amalgams (alloys involving mercury). [3] Pure substances that are liquid under normal conditions include water, ethanol and many other organic solvents. Liquid water is of vital ...
