Considering factors such as the "seasonal nature of releases, ambient temperatures, metabolic rates and duration of exposure", Environment Canada stated in 2014 that "it is proposed that ethylene glycol is not entering the environment in a quantity or concentration or under conditions that have or may have an immediate or long-term harmful effect on the environment or its biological diversity".In the U.S., airports are required to obtain stormwater discharge permits and ensure that wastes from deicing operations are properly collected and treated. Large new airports may be required to collect 60 percent of aircraft deicing fluid after deicing. Airports that discharge the collected aircraft deicing fluid directly to waters of the U.S. must also meet numeric discharge requirements for chemical oxygen demand. A report in 2000 stated that ethylene glycol was becoming less popular for aircraft deicing in the U.S., due to its reporting requirements and adverse environmental impacts (p. 213), and noted a shift to the use of propylene glycol (p. I-3). Other animals
Once kidney failure has developed in dogs and cats, the outcome is poor. The treatment is generally the same, although vodka or rectified spirits may be substituted for pharmaceutical grade ethanol in IV injections. See also

Coronary artery bypass surgery, also known as coronary artery bypass graft (CABG, pronounced "cabbage") is a surgical procedure to treat coronary artery disease (CAD), the buildup of plaques in the arteries of the heart. It can relieve chest pain caused by CAD, slow the progression of CAD, and increase life expectancy. It aims to bypass narrowings in heart arteries by using arteries or veins harvested from other parts of the body, thus restoring adequate blood supply to the previously ischemic (deprived of blood) heart. There are two main approaches. The first uses a cardiopulmonary bypass machine, a machine which takes over the functions of the heart and lungs during surgery by circulating blood and oxygen. With the heart in arrest, harvested arteries and veins are used to connect across problematic regions—a construction known as surgical anastomosis. In the second approach, called the off-pump coronary artery bypass graft (OPCABG), these anastomoses are constructed while the heart is still beating. The anastomosis supplying the left anterior descending branch is the most significant one and usually, the left internal mammary artery is harvested for use. Other commonly employed sources are the right internal mammary artery, the radial artery, and the great saphenous vein. Doctors were searching for an effective way to treat chest pain (specifically, angina, a common symptom of CAD) since the beginning of the 20th century. In the 1960s, CABG was introduced in its modern form and has since become the main treatment for significant CAD.
