IN THE LOWER CATCHMENT OF JIU RIVER BASIN, ACCORDING TO THE WATER FRAMEWORK
DIRECTIVE (2000/60/EC)

ABSTRACT. – Surface water pollution with heavy metals in the lower catchment of
Jiu river basin, according to the Water Framework Directive (2000/60/EC). The
Water Framework Directive establishes a single transparent, effective and
coherent water policy by defining a strategy to combat pollution by requiring
specific action programs.
Chemical pollution of surface water presents a threat to the aquatic environment
with acute and chronic toxicity to aquatic organisms, accumulation in the
ecosystem and losses of habitats and biodiversity, as well as a threat to human
health (art.1 from Directive 2008/105/EC regarding the environmental quality
standards for water policy).
The purpose of this study is to evaluate the chemical status for surface water
bodies in the lower catchment of Jiu river basin. The assessment was made taking
into account the water impact of four heavy metals: cadmium (Cd), nickel (Ni),
mercury (Hg) and lead (Pb).
Keywords: Water Framework Directive (WFD), chemical status, heavy metals.
