Benzene in General Environment

Andrzej Starek

Benzene is a primary industrial chemical and a ubiquitous environmental pollutant. Benzene occurs naturally as a component of petroleum and natural gas and also as a gas emissions from volcanoes and forest fires. There are number of petroleum products that contain benzene and are used in several industrial and household applications. For example, benzene is present in gasoline. Its the maximum content in gasoline was limited in 1998 to 1% v/v.

The general population is commonly exposed to benzene via respiratory tract. The main sources are traffic exhausts and cigarette smoke. Benzene exposures to the general population have been reduced by lowering its contents in gasoline and prohibiting smoking in public places. To improve air quality in the European Union set a limit value of 5 µg/m3 for benzene in 2008. The knowledge on the metabolism of benzene is basis for investigation of biomarkers of exposure to benzene.

Application of water treated with low-pressure, low-temperature glow plasma (nanowater) in food and cosmetic technology

Piotr Tomasik, Zdzisław Oszczęda

This review presents a current state of knowledge on water
treated with low-pressure, low-temperature glow plasma of low
frequency. This water is also known as nanowater. Its physical
and physicochemical characteristics is briefly presented followed
by the presentation of the effects of that water upon the plant
and animal production and application of nanowater in food
and cosmetics technologies.
