Coal is an important energy source for the development of modern society. The processing and utilization coal have brought significant economic benefits people, but at same time, a large amount coal-based solid waste produced. tar slag one many types waste. contains number PAHs (Polycyclic Aromatic Hydrocarbons) that are carcinogenic to humans therefore categorized as hazardous There historical stockpile slag, if not properly handled, it will cause great harm people environment; therefore, disposal slags hot issue scholars study. In this paper, toxic in were removed by subcritical extraction, extracts raffinates tested using infrared spectroscopy, GC-MS (gas chromatography–mass spectrometry), PY-GC-MS (Pyrolysis Gas Chromatography–Mass Spectrometry). results showed after three extractions 60 °C, there obvious aromatic hydrocarbon absorption peaks extracts, intensity hydrocarbons was significantly reduced. first extract, mainly aliphatic dominated; relative content 28.68%, 56.56%. second ethers 37.11%, 18.5%. third dominated, 81.78%. Only substance, benzaldehyde, detected substance included national list. After residue transformed from can be used directly, which convenient recycle future.

Polycyclic aromatic hydrocarbons (PAHs) are persistent organic pollutants that pose significant environmental and health risks due to their widespread distribution carcinogenic properties. Developing efficient environmentally friendly extraction methods for PAHs from complex matrices like bottom sediments is essential advancing pollution monitoring mitigation efforts. The influence of temperature time parameters water in a subcritical state on the widespread, contrasting physicochemical properties polycyclic sediment samples Lena River with varying initial pollutant content was studied. It shown optimal naphthalene 240°C 20 minutes, phenanthrene fluoranthene – 30 benzo(a)pyrene 250°C benzo(g,h,i)perylene 260°C 40 minutes. Under these conditions, proportion extracted varies 76% 85%. A comparison conducted widely used PAH based use toxic solvents standard techniques. established efficiency can be ranked as follows: ultrasound > saponification method. In this case, value coefficient during 1.23-1.29, - 1.35 1.34, ultrasonic method 1.10 1.08.
