What is it about?
This paper summarizes studies of sediment pollution due to oil and gas production. The goal is to highlight potential environmental risks associated with produced water management, including long-term contamination of sediments.

Why is it important?
The main pollutants in sediments resulting from oil and gas production are heavy metals, salts, naturally occurring radioactive materials (NORMs), oil and grease (O&G), benzene, toluene, ethylbenzene and xylene (BTEX), total petroleum hydrocarbon (TPH), and polycyclic aromatic hydrocarbon (PAHs). These pollutants reach sediments and water resources via pipeline leaks, truck spills, improper waste disposal, and underground injection. Methods to decrease contaminant risks in sediments include surface capping, bioremediation, and phytoremediation.
Perspectives
I believe this review article helps researchers and environmentalists to recognize the main contaminants in sediments from oil and gas industries, the major sources for the contaminants, and the most important methods for the removal.
