“…Massive myocardial necrosis after exposure to hydrogen sulfide (at >500 ppm for more than 40 min) confirmed through postmortem autopsy 9) and two victims without autopsy, one of whom died following massive cardiogenic pulmonary edema and the other died of acute cardiac infarction two months after exposure to the gas has been described previously 10) . Later two victims also presented abnormal ECG with elevated ST segment in the left precordial leads 10) . One surviving case has shown abnormal ECG such as a posterolateral myocardial ischemic changes, which had returned to normal gradually 11) .…”

“…Os casos de intoxicação por H 2 S são mais acentuados principalmente no setor industrial. Segundo Gregorakos et al (1995), as autópsias realizadas em funcionários que morreram em um acidente envolvendo vazamento de sulfeto de hidrogênio revelaram que os corpos possuíam edemas pulmonares, miocardite, hemorragia na mucosa gástrica, além do cérebro e da parte posterior do intestino apresentar a cor esverdeada e alguns casos de ataque cardíaco.…”

31 RESUMONeste trabalho de revisão foram avaliados os principais métodos utilizados para o tratamento de emissões atmosféricas contendo H 2 S, descrevendo suas vantagens e desvantagens. Buscou-se encontrar tecnologias mais adequadas para o tratamento do H 2 S emitido por reatores anaeróbios. Uma análise qualitativa dos vários métodos indicou que a utilização de absorção química com solução redox de ferro (III) reúne o maior conjunto de vantagens para o tratamento do H 2 S emitido por este tipo de reatores, como a possibilidade da reutilização da solução de ferro evitando gastos com reposição de reagentes e geração de um coproduto (enxofre elementar) que pode ser comercializado ou retornado ao meio ambiente em forma de insumos agrícolas.Palavras-chave: Sulfeto de hidrogênio. Tratamento de gases. Reatores anaeróbios. ABSTRACTIn this review it was assessed the main methods used for the treatment of H 2 S in atmospheric emission, describing its advantages and disadvantages. It was attempted to find more appropriate technologies for the treatment of H 2 S emitted by anaerobic reactors. A qualitative analysis of the several methods stated that the use of chemical absorption with iron redox solution (III) gathers the largest number of advantages for the treatment of H 2 S issued by these kind reactor, as the possibility of reusing the iron solution avoiding spending on reagents replacement and also generating a byproduct (elemental sulfur) which can be sold or returned to the environment in shape of agricultural inputs.Keywords: Hydrogen sulfide. Gas emissions treatment. Anaerobic reactors. INTRODUÇÃOA poluição atmosférica vem preocupando cada vez mais a sociedade, pois afeta diretamente a qualidade de vida de cada um. Os sistemas, de transporte e produção de energia, envolvidos na agricultura e processos industriais são grandes responsáveis pelas formas de poluição atmosférica que provêm do homem.

“…The respiratory system, the circulatory system and the nervous system may be severely affected by H 2 S exposures [1,2]. Manifestations of cardiac diseases induced by H 2 S poisoning have been well demonstrated, including angina attack, myocardial infarction, arrhythmias and heart failure [3,4]. The prognosis is extremely poor and the best therapy has not yet been determined.…”

Most cases of acute hydrogen sulfide (H₂S) poisoning in China are caused by sewage processing. With the rapid development of urbanization in China, H₂S poisoning is showing an increasing trend. Here, we report a case of survival from severe H₂S poisoning. A 40-year-old worker was found in the underground sewer lines. He was unresponsive with bilaterally dilated pupils and had poor oxygen saturation. After intubation, he was transferred to the intensive care unit. He developed respiratory failure, acute myocardial infarction,ventricular arrhythmia and left ventricular function impairment, requiring artificial ventilation with highly concentrated oxygen, hyperbaric oxygen treatment and drug therapy. Consequently, he completely recovered from the respiratory and cardiac failure. Cases of survival after severe H₂S intoxication have been rarely reported. Such exposures may bring about severe myocardial impairment, which is most likely to benefit from angiotensin-converting enzyme inhibition and β-blocker.
