Monoaromatic hydrocarbons (benzene, toluene, ethylbenzene and xylene), known as BTEX for short, cause various adverse health effects such as asthma, dizziness, fatigue, eye, nose and throat irritation and nausea.
Among the BTEX compounds, xylenes are highly reactive and cause ozone formation and thus climate change. BTEX has been measured extensively worldwide in recent years. There are two main sources of BTEX emissions in the air. The first of these are fuel or gas stations, vehicle maintenance facilities and many small factories and workshops-like facilities. The second is road traffic. Generally, high benzene concentrations are found on roadsides, tunnels and inside cars. Benzene and toluene are the dominant monoaromatic compounds. There is a tight correlation between BTEX concentration and road traffic flow. There are limitations in this regard in the European Union directives.
Accurate and reliable BTEX tests are very important for companies that manufacture a large number of products, from paints and adhesives to leather products and plastics. Performing these analyzes is a critical step in preventing exposure and contamination that can affect human health and the environment. On the other hand, it is also important in terms of complying with the legal regulations in force. These tests and analyzes are the key to keeping BTEX emissions at the desired levels. A wide variety of test methods are applied for BTEX compounds, including gas chromatography or photoionization detector. By identifying BTEX contamination, businesses can take critical steps for improvement.
