UK watchdog waited three years to investigate cancer-causing pollution at Teesside plant

Britain's environment watchdog knew a Teesside chemical plant was releasing harmful benzene gas in 2023 but did not investigate until 2026. Benzene can cause cancer, and the WHO says no amount is safe. Emissions rose from 13 tonnes in 2022 to 17 tonnes in 2024. A Greenpeace scientist called the delay a "travesty." The watchdog is now considering legal action.
