Data from: Global soil pollution by toxic metals threatens agriculture and human health

This dataset includes the attachments related to the research conducted by
Hou et al., titled "Global soil pollution by toxic metals threatens
agriculture and human health". Our study involved the compilation of
a comprehensive global dataset on soil contamination by arsenic, cadmium,
cobalt, chromium, copper, nickel and lead, sourced from investigations
encompassing sampling locations across various climate zones, geological
formations, and land usage patterns. Subsequently, advanced machine
learning methodologies were employed to identify regions with exceedance
of agricultural and human health thresholds. This research underscores the
critical impact of soil pollution on global food security and the
imperative alignment with Sustainable Development Goals.
