Descriptions:
{"pubchem": "Nitrous Oxide can cause developmental toxicity and female reproductive toxicity according to The National Institute for Occupational Safety and Health (NIOSH).", "chebi": "A nitrogen oxide consisting of linear unsymmetrical molecules with formula N<small><sub>2</sub></small>O. While it is the most used gaseous anaesthetic in the world, its major commercial use, due to its solubility under pressure in vegetable fats combined with its non-toxicity in low concentrations, is as an aerosol spray propellant and aerating agent for canisters of 'whipped' cream.", "chembl": "NITROUS OXIDE is a small molecule listed in the ChEMBL database and has reached clinical trial phase 3.0.", "wikipedia": "Nitrous oxide (dinitrogen oxide or dinitrogen monoxide), commonly known as laughing gas or nitrous, among others, is a chemical compound, an oxide of nitrogen with the formula N2O. At room temperature, it is a colourless non-flammable gas, and has a slightly sweet scent and taste. At elevated temperatures, nitrous oxide is a powerful oxidiser similar to molecular oxygen.\nNitrous oxide has significant medical uses, especially in surgery and dentistry, for its anaesthetic and pain-reducing effects, and it is on the World Health Organization's List of Essential Medicines. Its colloquial name, \"laughing gas\", coined by Humphry Davy, describes the euphoric effects upon inhaling it, which cause it to be used as a recreational drug inducing a brief \"high\". When abused chronically, it may cause neurological damage through inactivation of vitamin B12. It is also used as an oxidiser in rocket propellants and motor racing fuels, and as a frothing gas for whipped cream.\nNitrous oxide is also an atmospheric pollutant, with a concentration of 333 parts per billion (ppb) in 2020, increasing at 1 ppb annually. It is a major scavenger of stratospheric ozone, with an impact comparable to that of CFCs. About 40% of human-caused emissions are from agriculture, as nitrogen fertilisers are digested into nitrous oxide by soil micro-organisms. As the third most important greenhouse gas, nitrous oxide substantially contributes to global warming. Reduction of emissions is an important goal in the politics of climate change.\n\n"}
