Which fumigant is known to accumulate in body tissues?

Methyl bromide is known to accumulate in body tissues, making it unique among the options provided. When it enters the body, it can persist in various tissues due to its lipophilic nature, which allows it to dissolve in fats and cellular membranes. This accumulation can lead to both acute and chronic health effects, including neurotoxic effects, as higher concentrations build up over time.

In contrast, other fumigants like chloropicrin, sulfuryl fluoride, and phosphine do not exhibit the same level of tissue accumulation. Chloropicrin primarily affects the respiratory system and is rapidly metabolized and excreted. Sulfuryl fluoride is also less likely to accumulate as it is rapidly eliminated from the body after exposure. Phosphine is metabolized quickly and does not have the same potential for tissue retention. Understanding these differences is crucial for assessing the risks associated with fumigant exposure and ensuring safety measures are properly implemented.
