What are toxic substances in production?
Thread Content
One definition is that a substance is toxic if the amount that enters the human body exceeds 50g, as this amount can cause disruptions in the body’s normal functions. Is such a definition scientific? Is 50g really too much? Please give me your guidance.
Highly toxic substances are those that can cause severe damage to the body or lead to death even in amounts of less than 50 grams entering the human body, such as fluorine, hydrofluoric acid, phosgene, and carbonyl fluoride. Toxic substances are those that can cause damage to the normal functions of the human body when an amount of ≥50g enters the body, such as carbon dioxide, ammonia, carbon monoxide, vinyl chloride, methanol, ethylene oxide, carbon disulfide, hydrogen sulfide, etc.
Is 50g defined in too abstract a manner? In production, many toxic substances have lethal doses well below 50g; it’s necessary to distinguish between highly toxic substances and those that are only moderately toxic. What the original poster is referring to seems to fall within the category of moderately toxic substances
