Characteristics of heavy metals discharge from typical plants in Hechi city

摘要

This research paper uses Hechi heavy metals industrial pollution as a case study to analyze the industrial pollution emission characteristics of heavy metals from the variety of pollutants, temporal spatial distribution and industrial emissions between 2011 and 2013. By analyzing five kinds of heavy metals that also serve as environmental pollutants (Zn, Cd, Pb, Cu and As), the results show that Zn in water and soil is the leading pollutant and is found in the greatest degree. It is followed by Pb found in the atmosphere. The results also show that the center of the industrial park about 500m away from the annular zone should focus on monitoring heavy metal pollutants.
