Zusammenfassung |
In August and September 2002, concentrations of heavy metals (copper, lead, and
zinc) were 21-74% more than in previous years in Lithuanian rivers. Such a sudden increase
in heavy metal pollution reduces the value of any water body for fishing or recreation and
poses a potential risk to the environment and to human health. Droughts in the summer of
2002 led to forest and peat bog fires all over Lithuania and may have caused the increase
in concentrations of heavy metals detected in Lithuanian rivers in August 2002. The fires
could have changed the pH in the top layers of the soil, overcome geochemical barriers in
the soil and enabled heavy metals to migrate from the soil to the groundwater and from
river bottom sediments to the surface water.
