Oxygen depletion changes color
KUWAIT CITY, April 10: The Environment Public Authority (EPA) said the change in the sea water color and the soil in the western Doha area was a result of the low percentage of dissolved oxygen in the water due to the lack of currents because the area is almost landlocked.
The EPA said in a press statement a team from the EPA inspected the coast yesterday morning in response to a report about marine pollution in the western Doha area near the chalets following which samples were collected for laboratory tests.
The sources explained the cause of change in the color of water and soil which has turned black was due to physical and chemical properties, as this color results from an increase in hydrogen sulfide from microbial disintegration due to the increase in organic materials in the absence or low levels of dissolved oxygen in the water due to the lack of currents.
The sources added that this process is known as ‘anaerobic’ that are carried out by microorganisms “anaerobic bacteria”, which reduces sulphates and this process results in the emission of hydrogen sulfide gas.
The EPA also carried out an inspection tour of the Sulaibiya Industrial Zone in coordination with the Public Authority for Industry and the Ministry of Interior - Environmental Police. A number of factories were inspected, to ensure compliance with special environmental and engineering requirements and controls.
