Investigating the Impact of Oil Mulching with Petroleum Products on Water Quality

March 15, 2025

This article investigates the impact of oil mulching with petroleum products on water quality. Oil mulch, composed of heavy petroleum byproducts, has the potential to contaminate water resources with heavy metals and hydrocarbons. The study examined oil mulch samples from various regions in Khuzestan Province over short-term, medium-term, and long-term periods, as well as samples from the Abadan refinery under laboratory conditions simulating natural environments with a 24-hour contact time with water. The results revealed that oil mulch does not significantly increase water pollution in terms of heavy metals, and the levels of hydrocarbons detected were below permissible limits. The study concludes that while oil mulch may contribute to minor increases in certain pollutants, it does not pose a significant threat to water quality in terms of heavy metals and hydrocarbons.
