According to Japanese media reports earlier this month, on June 29th, a steam eruption of up to tens of meters occurred at an excavation site for a geothermal power plant in Lanetsu cho, Hokkaido, and high concentrations of arsenic were found in water samples taken near the site. Mitsui Petroleum Exploration Company, which is responsible for excavation, announced on the 18th of this month that it will "strive to control steam outbursts by mid August.". It is reported that large forests around the excavation site are changing color, and the company is investigating the impact on the environment.

According to Japanese media, regarding issues such as "continuous steam spewing from an excavation site in Lanetsu cho, Hokkaido, Japan, and high concentrations of arsenic detected from nearby water samples," Mitsui Oil Exploration Company, responsible for the excavation, stated on the 21st that "about 2000 liters of sewage leaked to areas outside the construction site while using pipelines to transfer arsenic containing sewage around the site.". At that time, the steam and other eruptions had caused discomfort in 17 people's bodies.
Arsenic is the main component of arsenic, commonly known as arsenic, and is a toxic element present in nature. Previous studies have shown that long-term exposure to arsenic may increase the risk of lung cancer, bladder cancer cancer, skin cancer and other cancers.
