Lead Contamination Analysis in Falun
Budget: $2 – $8 USD
1. Task
In this assignment, you work with similar scenario as in Exercise Overlay analysis:
The city of Falun is known for the thousand-year-old mining operations in the
Falu Mine, now a UNESCO World Heritage Site. It is estimated that there are
ten million tons of mining waste in and around the city of Falun. As a result of
the millennium-long mining activities, many square miles around the urban area
contain high levels of metals, particularly lead. The map below shows areas
where lead concentrations in the soil exceed 300 and 700 mg/kg TS, respectively.
Considering the scenario above, you need to produce the following:
a) Calculate the size of the area (in square kilometers), where lead concentrations exceed
than 300 mg/kg TS
b) Create a map showing the area of the city of Falun, where lead concentrations exceed
300 mg/kg TS. Information on the size of the area should be incorporated as part of this
map.
c) Calculate how many inhabitants are resided in areas where lead concentrations exceed
300 mg/kg TS
d) Create a map showing population distribution in the area where lead concentration
exceeds 300 mg/kg TS. Information on the number of inhabitants resided in the area
should be incorporated as part of this map.
e) Create a map showing all buildings located in the area where lead concentration 300
mg/kg TS exceed 300 mg/kg TS
