What environmental contaminant risk associated with leafy greens is noted to be a cumulative concern with daily intake of bok choy?

Heavy metals, such as cadmium, from contaminated soil.

When making any produce item a cornerstone of the daily diet, food safety considerations become more critical due to cumulative exposure over time. Like all leafy greens, bok choy has the potential to accumulate heavy metals, with cadmium specifically being mentioned as a contaminant that can be absorbed if the vegetable is grown in soil with environmental contamination. While this is a risk for any daily produce item, making bok choy a constant feature increases the cumulative burden of exposure. Sourcing from trusted local vendors or choosing organically grown options is suggested as a proactive measure to secure higher quality and minimize exposure to such environmental risks.
