Environmental monitoring showed no excessive levels of pollutants in the air outside the exclusion zone set up around the blast site, but found excessive levels of cyanide in water.
Cyanide was detected in 33 of 44 water monitoring sites. Six sites inside the exclusion zone contained cyanide 0.94 to 36.8 times more than levels officially regarded as safe.
Cyanide was also found in underground water near the blast site but the levels were not excessive, the report said.
Han Fengqun, a 56-year-old who was rescued 65 hours after the blast, is in a stable condition after 10 days in intensive care, said a doctor in charge of his treatment. Han owned a convenience store near the warehouse.
