What is one of the major concerns with using methyl bromide as a fumigant?

Methyl bromide has garnered significant concern primarily due to its environmental impact, particularly its role in ozone depletion. When released into the atmosphere, methyl bromide contributes to the thinning of the ozone layer, which is crucial for protecting life on Earth from harmful ultraviolet (UV) radiation. The environmental risks associated with methyl bromide prompted international agreements, such as the Montreal Protocol, to phase out its use due to its harmful effects on both human health and ecosystems.

While methyl bromide does have high volatility, low toxicity compared to other fumigants, and a relatively short exposure time required for effective fumigation, these factors do not overshadow the pressing environmental concerns linked to its application. The emphasis on sustainable practices and the protection of the ozone layer makes the environmental impact of methyl bromide a significant issue in its usage as a fumigant.
