Changyi Petrochemical recently commissioned a third party to monitor air pollutants and noise around its plant, and released the data on the national company information platform for the public. Commissioning a professional institute has helped to reach a true, precise and integral result, which has helped the company better understand its pollutant emissions and related environmental impact so as to standardize pollutant management. The monitoring information covers fumes, wastewater and noise. The fumes include sulfur dioxide, nitric oxide and particulate matter. The wastewater involved chemical oxygen demand, PH and ammonia nitrogen. The noises were monitored during daytime and nighttime.
