Cyanogen is the chemical compound with the formula 2. It is a toxic gas with a pungent odor; the molecule is a pseudohalogen. Cyanogen molecules consist of two CN groups – analogous to diatomic halogen molecules, such as Cl2, but far less oxidizing; the two cyano groups are bonded together at their carbon atoms: N≡C−C≡N, although other isomers have been detected. The name is used for the CN radical, hence is used for compounds such as cyanogen bromide. Cyanogen is the anhydride of oxamide: H2NCCNH2 → NCCN + 2 H2Oalthough oxamide is manufactured from cyanogen by hydrolysis: NCCN + 2 H2O → H2NCCNH2 Cyanogen is generated from cyanide compounds. One laboratory method entails thermal decomposition of mercuric cyanide: 2 Hg2 → 2 + Hg22Alternatively, one can combine solutions of copper salts with cyanides, an unstable copper cyanide is formed which decomposes into copper cyanide and cyanogen. 2 CuSO4 + 4 KCN → 2 + 2 CuCN + 2 K2SO4Industrially, it is created by the oxidation of hydrogen cyanide using chlorine over an activated silicon dioxide catalyst or nitrogen dioxide over a copper salt.

It is formed when nitrogen and acetylene are reacted by an electrical spark or discharge. Cyanogen is NCCN. There are less stable isomers. Isocyanogen is NCNC, diisocyanogen is CNNC, diazodicarbon is CCNN. Paracyanogen is a polymer of cyanogen, it can be best prepared by heating mercuric cyanide. It can be prepared by heating silver cyanide, silver cyanate, cyanogen iodide or cyanuric iodide, it can be prepared by the polymerization of cyanogen at 300 to 500 °C in the presence of trace impurities. Paracyanogen can be converted back to cyanogen by heating to 800 °C. Based on experimental evidence, the structure of this polymeric material is thought to be rather irregular, with most of the carbon atoms being of sp2 type and localized domains of π conjugation. Cyanogen was first synthesized in 1815 by Joseph Louis Gay-Lussac, who determined its empirical formula and named it. Gay-Lussac coined the word "cyanogène" from the Greek words κυανός and γεννάω, because cyanide was first isolated by the Swedish chemist Carl Wilhelm Scheele from the pigment "Prussian blue".

By the 1850s, cyanogen soap was used by photographers to remove silver stains from their hands. It attained importance with the growth of the fertilizer industry in the late 19th century and remains an important intermediate in the production of many fertilizers, it is used as a stabilizer in the production of nitrocellulose. In 1910 a spectroscopic analysis of Halley's Comet found cyanogen in the comet's tail, which led to public fear that the Earth would be poisoned as it passed through the tail; because of the diffuse nature of the tail, there was no effect when the planet passed through it. Like other cyanides, cyanogen is toxic, as it undergoes reduction to cyanide, which poisons the cytochrome c oxidase complex, thus interrupting the mitochondrial electron transfer chain. Cyanogen gas is an irritant to the eyes and respiratory system. Inhalation can lead to headache, rapid pulse, vomiting, loss of consciousness and death, depending on exposure. Lethal dose through inhalation ranges from 100 to 150 milligrams.

Inhalation of 900 ppm over a period of 10 minutes is considered lethal. Cyanogen produces the second-hottest-known natural flame with a temperature of over 4,525 °C when it burns in oxygen.

National Sanitary Surveillance Agency

Brazilian Health Regulatory Agency is a regulatory body of the Brazilian government, created in 1999 during President Fernando Henrique Cardoso's term of office. It is responsible for the regulation and approval of pharmaceutical drugs, sanitary standards and regulation of the food industry; the agency bills itself as "an independently financially autonomous" regulatory body. It is administered by a five-member collegiate board of directors, who oversee five thematic directorates, assisted by a five-tier oversight structure. Since September 2018 the agency is headed by William Dib. Brazil is the world's largest consumer of pesticides; these pesticides are used in the production of soy and corn. The number of approved pesticides increased "rapidly" between 2015 and 2019. RT reported in 2019 that ANVISA had relaxed pesticide regulations and that the approval process had been accelerated as within the first seven months of the year 262 new pesticides were approved, 82 of them classified as "extremely toxic".

Teresa Cristina, the agriculture minister, noted that "there is no general liberation" of new pesticide registrations and no reason for concern when pesticides are used as instructed. Regulation of therapeutic goods Epidemic Intelligence Service World Health Organization

Eight Great Yakṣa Generals

The Eight Great Yakṣa Generals, or the Eight Yakṣa Generals are guardian deities in Buddhism. They are guardian of the north and king of the yakṣas. In East Asia, they are variously known as the Eight Great Yakṣas, the Eight Great Heavenly Kings, the Eight Brothers of Vaiśravaṇa; the term yakṣarākṣasa has been used as a general term to denote the many classes of spirits in Indian mythology, combining the words yakṣa and rākṣasa. According to Buddhist mythology, Vaiśravaṇa is the chief of these beings, long ago dwelt together with them in the realm of darkness; when Vaiśravaṇa converted to Buddhism, the many demonic spirits under his jurisdiction assumed the role of devotees to the Buddha. Malevolent beings, their conversion led to their deification as benevolent guardian deities. Among the many yakṣas under Vaiśravaṇa's rule, the Eight Great Yakṣa Generals are ranked at the top of the hierarchy. Always at Vaiśravaṇa's command, these deities command 36,000 yakṣas that serve their king and are said to protect those who venerate them.

A similar list may be found among the Twenty-Eight Great Yakṣa Generals. Their names are given in the Commentary on the Mahāvairocana Abhisaṃbodhi Tantra as follows: Twelve Heavenly Generals
