Electomagnetic

field can influence all
organisms. Effects depend on
intencity

of the
field.

The most popular artificial sources of
electromagnetic fields in the environment
include:



broadcasting antennas
of cellular telephony
base stations



base stations antennas
of different systems
for land mobile
radiocommunications



overhead lines



There

are

many
sources

of
pollution

in



The

Odra River
area
.
Mainly

matallurgy

and


heavy industry.
There

are

about

1700


potential

sources

of
pollution



and
about

700


significantly

Surface water quality monitoring
observations indicate a clear improvement in
water quality in the water courses situated in
Wrocław
. This is due to the collapse of
industry responsible for water contamination
and due to reduction in the amount of
sewage discharged from the sources of
pollution that still exist. This is also stems
from substantial investment efforts made to
modernise

the existing wastewater treatment
plants and to erect new ones.

city falls into the 3rd quality class
(satisfactory), and in some cases into the 2nd
class (good quality).



Floods

results

of
the

analyses

made

by

Regional

Chemical and
Agricultural

Station

shows

that

the

content

of
phosphorus
,
potassium

and
magnesium

soils

with

very

low

content

of
the

above

macroelements

represent

beetwen

20% and
40% of
all

arable

land.
The

content

od heavy
metals

has

decreased

in

last

5
years
.



Waste
is

one of
the

biggest

environmental

problems

in

Wrocław.
It

is

coused

by
the

very

high waste
production

level

and
low

recycling
level
.
