Environmental Impacts of Petroleum Pollution in South of Iran
摘要
The Persian Gulf coastline and South of Iran is one of country’s most important oil producer locations, affecting an area over 5000 km2. There are rocky valleys and mountains, dam reservoirs, agricultural lands, large permanent rivers and seasonal streams, environmentally sensitive areas (ESAs), deserts, the Persian Gulf coastline, commercial ports, and aquaculture farms in this area. Oil leakage from oil transmission lines caused by corrosion can cause pollution in any of the mentioned ecosystems. The development of an action plan for environmental emergencies suitable for each climate is an important issue in pollution risk management. Pipeline oil spills may be transferred to different ecosystems by draining into permeable soil layers or via flowing into the bedrock or river surface. Although a large amount of the leaked oil can be removed through proper planning and availability of machines and equipment to deal with oil pollution in aqueous and land environments, some of the pollutants will inevitably be absorbed by soil texture. Therefore, local oil and gas company needs to have a soil remediation program. Considering the differences in soil texture and usage, several sites have been selected in various areas to which the removed soil contaminated with petroleum substances will be transferred for remediation. Once the soil remediation process is finished and the soil that was polluted reaches the permissible level, it is returned to its original location. This chapter has reviewed some cases of oil pollution in various environments, discussed oil pollution hazards, and then introduced the various soil remediation sites used by a local oil and gas company.
