An interesting case of characteristic methanol toxicity through inhalational exposure

Abstract

Methanol poisoning is rare but carries high risk of morbidity and mortality. Most of the cases witnessed in emergency are due to consumption of adulterated alcohol. Here we are reporting a very rare case of methanol poisoning through inhalational exposure leading to putamen necrosis and decreased visual acuity. He had dyselectrolytemia and metabolic acidosis which was successfully managed with early intervention. Its importance lies in the fact that inhalational methanol poisoning is an entity which if picked up early can prevent long-term neurological sequelae.

Risk mitigation of biodiesel production through the replacement of methanol by ethanol in the production process

“…Coma and death can occur in cases of significant exposures. Occupational exposure occurs mainly by inhalation of vapors …”

“…7,10 Also in this research, a specific work about the risks of exposure to methanol in biodiesel plants was found. 8,11 However, this study focused on the health of the worker subjected to inhalation of high rates of this product, and not to other issues such as fire and explosions. In addition, the study does not propose a solution to reduce the risks associated with the use of methanol.…”

“…In Brazil, most biodiesel producers use methanol in their production process . In this sense, it is pointed out that the use of methanol poses several health and safety risks, such as fire, explosions, and serious effects to human health …”

“…6 In this sense, it is pointed out that the use of methanol poses several health and safety risks, such as fire, explosions, and serious effects to human health. [7][8][9] An alternative to these risks would be the substitution of methanol with ethanol. However, the substitution is not simple since the use of ethanol has a lower yield in the production of biodiesel and other operational problems, which ends up increasing the cost of production.…”

Methanol-induced parkinsonism and cerebral vasculopathy due to perfume inhalation

“…Its illegal oral consumption is the most commonly reported route of toxicity in the literature 1. Methanol poisoning is thought to cause severe morbidities such as vision loss, metabolic alterations and irreversible neurological dysfunction, and it may even lead to mortality 2. We are reporting an unusual presentation of incidental methanol intoxication through the inhalation of homemade perfume during the manufacturing process.…”
