Equilíbrio QuímicoUFTM · 2013MédioEntre para guardar nos favoritosO incêndio na boate Kiss, em Santa Maria (RS), ocorrido no início deste ano [2013], trouxe à tona uma série de questões sobre a segurança dos estabelecimentos e também sobre o atendimento a vítimas de grandes incêndios. Uma delas é por que foi preciso trazer dos Estados Unidos uma substância tão simples – uma vitamina B injetável – para atender os pacientes que, segundo exames, foram intoxicados com cianeto?
O gás cianídrico liberado na queima da espuma, utilizada para melhorar a acústica da casa noturna, intoxicou a maior parte das vítimas, segundo perícia.
“É descaso e ignorância”, resume o toxicologista Anthony Wong, diretor do Ceatox (Centro de Assistência Toxicológica do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo). Segundo ele, é inadmissível que o país não tenha a substância e que seu uso não seja difundido entre médicos e socorristas, como acontece em outras partes do mundo.
A hidroxocobalamina, que faz parte do complexo B, é usada em altas concentrações como antídoto para o cianeto. O gás, o mesmo que já foi usado no extermínio de judeus nos campos de concentração nazistas, é subproduto da queima de diversos componentes usados na indústria, como o plástico, o acrílico e a espuma de poliuretano. Segundo os peritos que investigam o incêndio em Santa Maria, essa última foi usada no isolamento acústico da boate.
Capaz de matar em poucos minutos, o cianeto bloqueia a cadeia respiratória das células, impedindo que o oxigênio chegue aos órgãos e tecidos. Quando usada logo após a exposição, a hidroxocobalamina salva vidas. “O efeito é tão rápido que parece até milagroso”, conta Wong. Mas isso não é algo que os médicos aprendem na escola: “São poucas as faculdades que oferecem curso de toxicologia e, nas que tem, a matéria é opcional”.

Informações adicionais:
• O gás cianídrico é o cianeto de hidrogênio (HCN) no estado gasoso.
• A fórmula estrutural da hidroxocobalamina é:
• A massa molar da hidroxocobalamina é aproximadamente igual a 1,3 × 10³g/mol.
O cianeto de hidrogênio em solução aquosa é um ácido muito fraco. O hidróxido de potássio é uma base muito forte. O produto iônico da água, Kw, a 25 ° C, é igual a 1 × 10–14. Logo, as soluções aquosas de cianeto de potássio, nessa temperatura, apresentam2593B4F1-E9 Matemática

Quem ama inventa
Quem ama inventa as coisas a que ama...
Talvez chegaste quando eu te sonhava.
Então de súbito acendeu-se a chama!
Era a brasa dormida que acordava...
E era um revoo sobre a ruinaria,
No ar atônito bimbalhavam sinos,
Tangidos por uns anjos peregrinos
Cujo dom é fazer ressurreições...
Um ritmo divino? Oh! Simplesmente

Batendo juntos e festivamente,

Ó! meu pobre, meu grande amor distante,
Nem sabes tu o bem que faz à gente

(Alto Xingu Indians in Central Brazil.Sebastião Salgado/Amazonas Images)Sebastião Salgado’s blue eyes have seen a bit of everything in this world – and this might not even be an exaggeration. For the past eight years in particular, the 69-year-old Brazilian photographer has travelled to more than 30 isolated regions of the world, collecting images of dozens of remote tribes, endangered animals and unusual landscapes.The Genesis project is a singular photographic journey that began in 2004 and ended in 2012, at a cost of one million Euros a year. The result will be shown in magazines, books, a documentary by Wim Wenders and a series of exhibitions around the world, each displaying some 250 black-and-white photos.The first exhibition will open in London on April 11, with former Brazilian President Lula – Salgado’s long-time friend – as special guest. “We want to create a little movement around these photos to provoke a debate on what we need to preserve,” he says. Salgado defends environmental causes through his organization, Instituto Terra. Even after travelling to so many exotic places, Salgado, now living in Paris, still takes vacations in Brazil. Here are excerpts from a conversation Salgado had with Folha, with new details about his travels, photographic techniques and new environmental projects.• Coldest tripI visited the Nenets, in the Yamal peninsula, in northern Siberia, Russia. They are a nomadic tribe who raise reindeer in extreme Arctic conditions. When I went there it was spring and weather ranged between -35ºC and -45ºC. I didn’t wash myself for 45 days. They don’t take baths because there is no water. The only way to get water is to break off a piece of ice and warm it in a pot.• Frozen equipmentI used a Canon, an EOS1 Mark III, a very powerful machine. The problem was the batteries. In the Siberian temperatures, they quickly lost power. On average, I take 2,500 shots per battery, but this time I could only take 300-400 photos before the battery stopped working. I would put it inside my clothes, my assistant would give me another one, I would take 300 more pictures and, when that battery ran out energy, I would take out the other one and it would work again.• Going digital for the first timeI started Genesis with film and changed to digital. The airport X-Ray scanners degrade the quality of film, and so I decided to change to digital and was quite surprised. Quality was better than the one I had with negatives in medium format. I turned off the screen on the back of the camera, and used my camera as I have always done. When I came back to Paris, I printed contact sheets and edited the photos using a magnifying glass, because I don’t know how to do it in the computer.• Stone AgesI met tribes that are still living in the Stone Ages, with working tools such as stone hammers. There were clans of about 10 people living in treetops. They had already seen white people before. They looked towards the direction I had come from and the chief asked me whether I was part of the white people clan that usually came from that direction. Because, for them, the world is all made of clans.• Brazilian arrowsI met the Zo’e tribe, in Brazil, who were first discovered 15 years ago and live in a state of total purity. You see the guy working with an arrow. He warms it, put some weight on it, a straight feather if he wants a quicker arrow, a rounder one to have it slower. It is the same science as for rockets. And he’s got the same problem as in Cape Canaveral, to recover his rockets. If his ballistic calculations are wrong, he loses his arrow. He takes only 10 arrows with him when he goes hunting, no more than that.• Activist or photographer?Photography is my life. When I am taking photos, I am in a deep trance. When I have my camera and am travelling with the Nenets, it’s my life, morning to night. I have taken incredible photos, but my life is also the environment and Instituto Terra.(www.worldcrunch.com.

The only way to get water is to break off a piece of ice and warm it in a pot.• Frozen equipmentI used a Canon, an EOS1 Mark III, a very powerful machine. The problem was the batteries. In the Siberian temperatures, they quickly lost power. On average, I take 2,500 shots per battery, but this time I could only take 300-400 photos before the battery stopped working. I would put it inside my clothes, my assistant would give me another one, I would take 300 more pictures and, when that battery ran out energy, I would take out the other one and it would work again.• Going digital for the first timeI started Genesis with film and changed to digital. The airport X-Ray scanners degrade the quality of film, and so I decided to change to digital and was quite surprised. Quality was better than the one I had with negatives in medium format. I turned off the screen on the back of the camera, and used my camera as I have always done. When I came back to Paris, I printed contact sheets and edited the photos using a magnifying glass, because I don’t know how to do it in the computer.• Stone AgesI met tribes that are still living in the Stone Ages, with working tools such as stone hammers. There were clans of about 10 people living in treetops. They had already seen white people before. They looked towards the direction I had come from and the chief asked me whether I was part of the white people clan that usually came from that direction. Because, for them, the world is all made of clans.• Brazilian arrowsI met the Zo’e tribe, in Brazil, who were first discovered 15 years ago and live in a state of total purity. You see the guy working with an arrow. He warms it, put some weight on it, a straight feather if he wants a quicker arrow, a rounder one to have it slower. It is the same science as for rockets. And he’s got the same problem as in Cape Canaveral, to recover his rockets. If his ballistic calculations are wrong, he loses his arrow. He takes only 10 arrows with him when he goes hunting, no more than that.• Activist or photographer?Photography is my life. When I am taking photos, I am in a deep trance. When I have my camera and am travelling with the Nenets, it’s my life, morning to night. I have taken incredible photos, but my life is also the environment and Instituto Terra.(www.worldcrunch.com.
