Description:
This research has been done in the marine waters of Bushehr province in Persian Gulf in the
geographical district of 52° 06ʹ to 52° 34ʹ E to 27° 23ʹ
to 27° 46ʹ N conducted from the far east
south of Boushehr province (Nayband headland) to the western south of Kangan (Berkeh
choopan) located in the Persian Gulf using local fiberglass floats in 16 stations in spring, summer,
fall and winter in 2011.
The present study seeks to protect/monitor environmental conditions stemming from the effect of
“special economic region-pars energy” on the biological resources of Persian Gulf. This research
follows the similar research which had been done before (in 2006) by the oil research institute.
All the results which determine the progress have been compared with the results of the performed
results by the oil research center. They were also compared with the national standards
(organization of environmental protection) and global standards (global health organization and
American environmental agency).
Thus, physiochemical factors such as temperature, salinity, acidity, dissolved oxygen, tarnishing
and chemical oxygen seeking were recorded and measured. Nutrient materials such as silicate,
phosphate, nitrate, ammonia, sulfides and organic carbons were investigated. The environmental
conditions of the investigated waters were reported normal compare to the whole region. Small
variation was reported around the exhausting wastewaters.
The deposition of the investigated regions has had sandy graining. The organic materials were
also allowed.
The concentration of Nitrite, nitrate, ammonia, phosphate, silicate and sulfide is sometimes lower
than the allowed level. But, there had been observed large amount of increase of phosphate and
sulfide compare to the previous studies. The issue of the increase of phosphate has been seen in
other studies. (Izadpanahi et al, 2005, 2009)
Other organic and mineral contaminants (heavy metals) were investigated as well. It can be
concluded from the changes of the concentration per year that metals such as mercury, lead,
cadmium, zinc, chromium, nickel were increasing through the year in water and precipitation
phases.
Other metals such as iron and copper have had experienced the same progress with steeper
gradient.
Comparing the measured values with the allowed limits in different regions of the region (nonindustrial,
industrial, inside the development region) indicate the comprehensive development in
the whole region.
The total concentration of oil hydrocarbons, aliphatic hydrocarbons and aromatic multi cyclic
hydrocarbons were also investigated.
The obtained results suggest that fortunately the investigated region is appropriate in normal
circumstances from the pollution viewpoint.
Aerobic and anaerobic bacteria, plankton, benthos were investigated as well. The concentration
of aerobic bacteria had no significant differences with each other except in spring p=0.001 and
summer p=0.041
Anaerobic bacteria had no significant relation with each other in water phase and sediment phases.
(P=0.05) The concentration of phytoplankton and zooplanktons were similar in different seasons
of the year. They were lower than the other studies. Comparisons of the abundance of benthos
with other regional studies inside the Persian Gulf suggest that the habitat of such creatures was
not destroyed due to the industrial activities so far.
High difference or small differences of the measured values of many parameters (specially
contaminants) shows the effectiveness of the mainstream of the water of Persian Gulf on
developing contaminants inside the region (Siraf seaport to Kangan seaports)
