Exposure of Iran among the vast Siberia
territories in the north, the Mediterranean Sea in the West,
Arabian deserts in the southwest and Indian lands in the East
has been affected its weather within the certain period of years.
Over the past decades, dust phenomena have caused many
problems for the residents of South and South West regions of
the country. Since the Karun River as the largest and the most
watery rivers of Iran enjoyed of a great strategic importance in
the region its hygiene conservation is considered the most
significant affair. This study was conducted to evaluate changes
in several important water quality parameters including
turbidity, EC, TDS, temperature and PH affected by dust
phenomenon and determine their violations of domestic and
international standards. To determine changes in these
parameters 11 sampling stations were determined. All
measurements were carried out during 153 days in which
Ahvaz City suffered from dust phenomenon. Measurement
results indicate that all the parameters have been significant
changes due to the impact of dust phenomena. And the amount
of three parameters including EC, TDS and Turbidity was
beyond the standard levels while two parameters including
temperature and pH were placed in the range of standard
levels
