Boston College Global Observatory on Planetary Health stated that only 20% of approximately 325,000 existing synthetic substances have published toxicology data. [^1]

A study by the Global Observatory of Access to Skin Health (SkinObservatory) determined that 42.6% of the 136 countries surveyed reported changes in the prevalence and/or severity of skin diseases related to climate change. [^2]

The filing dates for these reports are October 3 and October 2, 2026, respectively. [^1][^2]
