Which fumigant has a low relative toxicity?

• A. Methyl bromide
• B. Hydrogen cyanide
• C. Carbon tetrachloride
• D. Phosphine

Answer: (C)

Carbon tetrachloride is recognized for having a relatively low toxicity compared to the other listed fumigants. This characteristic makes it less harmful to humans and non-target organisms when used properly. Toxicity levels are crucial when selecting a fumigant, as lower toxicity generally means that the material is safer to handle and poses fewer risks during application and exposure. Methyl bromide, hydrogen cyanide, and phosphine, on the other hand, are classified as having higher toxicity levels. Methyl bromide is well-known for its acute toxicity and negative environmental impacts, particularly regarding ozone layer depletion. Hydrogen cyanide presents significant health risks and can be lethal in low concentrations. Phosphine, while effective as a pest control agent, is also highly toxic and requires stringent safety measures during handling and application. Understanding the toxicity profiles of these fumigants is essential in the context of agricultural safety, pest control efficacy, and regulatory compliance. Carbon tetrachloride's lower relative toxicity allows for its use in applications where safer handling practices are prioritized.
