Abstract [en]

A large part of the center of the city of Uppsala is located on postglacial

clay. This clay often contain sulfur, this in the form of sulfide, and thus it

is generally called sulfide clay (or sulfidlera in Swedish). The amount of

sulfide in the clay varies from location to location. When the sulfide-rich

postglacial clay comes in contact with the air it oxidizes and can give rise

to acid leachate and leaching of heavy metals that were bound to the

sediments. The knowledge of this has made the interest of sulfide content

in soils greater in recent years, this during for example excavations on

building sites. The aim of this project is therefore to summarize and

present data related to sulfide-rich sediments in a perspicuous way, and

thus make it easier to survey the measures that could be necessary to take

into consideration for construction work in the city of Uppsala. A lot of

the data is taken from the archive of Bjerking AB, but some of the

information on sites with sulfide rich clay is taken from Miljökontoret.

Using the computer program MapInfo, the locations with sulfide rich

soils has been marked on a map of Uppsala and additional information

about for instance layering, NNP and pH is connected to these markings.
