Toroku arsenic disease

The Toroku region experienced severe arsenic contamination from mining operations, affecting air, water, and soil quality throughout the surrounding valleys.

Between 1920 and 1962, the Sumitomo Metal Mining Company operated a refinery that released arsenic-containing emissions, leading to multiple deaths and widespread illness.

Medical examinations of Toroku residents since 1974 have shaped Japan's understanding of industrial pollution impacts on community health.

Annual health screenings continue for affected residents, focusing on symptoms involving the sensory nervous system, skin conditions, and respiratory problems.

The Toroku case led to significant legal proceedings when residents pursued action against Sumitomo Metal Mining Company for environmental contamination.
