Urbanization Associated with Heavy Metal Pollution
A Review of Threats to Drinking Water Source Quality of Changchun City, in NE China.
Shihan Zhang, MLWS 2022
Changchun is a typical city that experienced significant urbanization constructions in the past
decades. With the continuous economic development, the expansion of the city, and the
improvement of people's living standards, the heavy metals pollution of drinking water resources
in Changchun will rapidly increase. Drinking water is an essential and fundamental requirement
for supporting human living. However, heavy metal acclamation in the drinking water resources
can affect the drinking water quality and threaten Changchun residents. Comparing the data of
Xinlicheng reservoir and Shitoukoumen reservoir indicates the urbanization affected by heavy
metals pollution from point and nonpoint sources. The second Songhua river also suffers the
heavy metals pollutants from urban sewage and industrial wastewater. In addition, the heavy
metal sediment in the Second Songhua river might also come from the sediment transport from
other cities through the river basin. This paper lacks primary data to support the evidence, which
might result from the reliance on secondary data sources. This study is limited to the published
literature on the topics of interest outlined earlier. Therefore, the Changchun government needs
particular policies to address the problem of heavy metal pollution while simultaneously
balancing the rise of urbanization and environmental harm.
