Benzene is also known as benzene. It is often a colorless liquid. Benzene, which is very poorly soluble in water, mixes quickly with air. It is a highly flammable substance. Benzene can be found naturally in air, water and soil. Benzene is the simplest member of the class of organic compounds called aromatic hydrocarbons.

Benzene is used in various fields in industry. Used in plastic production, nylon components and synthetic detergent production. In addition, benzene is used as a starting material in paint production, in the production of insecticides and in aircraft fuel.

Benzene is widely available in the environment. This is due to various industrial plants. The benzene level in the air increases by evaporation from the exhausts of motor vehicles, the emissions of burning coal and oil, and from service stations. Another source of benzene in the air is cigarette smoke. Benzene in the air reacts with other chemicals and decomposes in a short time. It can accumulate in the soil with precipitation.

Benzene affects human health depending on the amount and duration of exposure. Prolonged exposure to benzene results in detrimental effects on tissues that make up bone marrow and blood cells. It also increases the risk of infection and breaks the body's resistance to cancer. Benzene causes blood cancer as a carcinogen.

In a research conducted in 1990, benzene was found in some soft drinks. Benzene was subsequently recognized as a carcinogenic substance. The amount of benzene is particularly high in dietary drinks and in beverages where vitamin C is high. This is due to the low amount of sugar. In the United States in 1998 and in Europe in 1999, cola drinks were picked up due to benzene contamination. According to the directives of the European Union, the benzene limit in drinking water was determined as 1 ppb.

Benzene determination is also performed in laboratories within the scope of chemical tests. During the studies, the standards prepared by local and foreign organizations are complied with.
