What is BTEX soil?

Abstract. BTEX is a general designation of benzene, toluene, ethylbenzene and xylene, which has been received wide attention because of its high biological toxicity. To investigate its environmental behavior in soil would help to understand its environmental fate and to evaluate its risks to ecosystems and human health …

What is BTEX analysis?

OI Analytical’s BTEX/GRO Analysis System is the total package for analyzing Benzene, Toluene, EthylBenzene, and Xylenes (BTEX), as well as gasoline range aromatics, and aliphatics in water, soil, and solids based on USEPA methods.

Does petrol have toluene?

Toluene is a seven-carbon aromatic hydrocarbon compound that is a minor component (∼5%) of all gasoline. Toluene is a colorless, flammable liquid that is about 15% lighter than water.

Is BTEX carcinogenic?

Health standards for BTEX Benzene is a known carcinogen (cancer causing). The ambient air quality objectives to protect human and environmental health are 3 ppb for benzene, 100 ppb for toluene and up to 200 ppb for xylene—based on the ambient concentrations of these chemicals being averaged over a yearly period.

Is petroleum hydrocarbon a VOC?

Petroleum contains a wide variety of volatile organic compounds (VOCs). Due to their low boiling points, VOCs can be emitted to the atmosphere and immediately contaminate the air.

What is BTEX compound?

BTEX refers to the chemicals benzene, toluene, ethylbenzene and xylene. These compounds occur naturally in crude oil and can be found in sea water in the vicinity of natural gas and petroleum deposits. Other natural sources of BTEX compounds include gas emissions from volcanoes and forest fires.

How do BTEX gases affect health?

Prolonged (chronic) exposure to BTEX compounds can affect the kidney, liver and blood systems. Long-term exposure to high levels of the benzene compound can lead to leukemia and cancers of the blood-forming organs.

Is BTEX flammable?

It is a highly flammable liquid that is colorless and has a gasoline like odor that is often described as slightly sweet.
