Groundwater testing at the site of Tokyo's planned new wholesale market in Toyosu has found the presence of two toxic chemicals at levels that exceed environmental standards, the Tokyo Metropolitan Government said Thursday.

Benzene and arsenic were both detected around an area scheduled to handle fruit and vegetables in the market, which has been built to replace the aging Tsukiji fish market.

The results showed the level of benzene reached 0.014 milligrams and 0.011 milligrams per liter at two locations, exceeding the environmental standard of 0.01 milligram.
