| description | A study has been conducted for spilled crude oil in sand reservoir 2x2x1m3 each
contains 1200 l water from Garmat Ali River, crude oil was poured in each reservoir as
follows: 1.2, 2.4 and 3.6 l in the first three reservoirs respectively while the fourth was
left without oil as control. The four reservoir were exposed to climate under the sun and
wind, the changes in the spilled oil layers were investigated as well as some
environmental parameters for water underneath which are temperature, salinity and
dissolved oxygen. Moreover, petroleum hydrocarbons were measured after certain
intervals of 7, 12, 22 and 60 days of exposure. Spilled oil layers reduced with time as
petroleum hydrocarbons dissolved in the water for reservoir with oil in which
concentrations of dissolved petroleum hydrocarbons increased directly with thickness of
oil spill compared with control reservoir. After a week of exposure dissolved petroleum
hydrocarbons measured were 833.96 , 1564.33 and 2031.48 μg/l in the reservoir 1,2 and
3 respectively compared with 53.04 μg/l in the control reservoir. These levels were
decreased with time in which they reached to 355.22, 623.65 and 1549.21 μg/l in the
reservoirs 2 , 3 and 4 respectively after 60 days of exposure. Results were explained on
the basis of biodegradation, photo-oxidation due to increase temperature and decrease
dissolved oxygen accompanied the exposure, in which temperature increased directly
while dissolved oxygen decreased with exposure time and thickness of spilled oil. More
over, salinity is increased with time to be 1.57, 2.41, 2.34, 2.49 and 2.61 ‰ during
exposure times 1 hour, 7, 12, 17 and 22 days respectively in the reservoir No. 4. As
thickness of oil slick increased the salinity is increased to become 2.12, 2.22 and 2.61‰
in the reservoirs 2 , 3 and 4 respectively after 22 days of exposure to natural conditions |
