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.

The impact of stochastic resonance as a complement to physiotherapy in the reeducation of locomotion in patients with multiple sclerosis

Mateusz Bartczyk, Andrzej Suchanowski, Marta Woldańska-Okońska, Jakub Świderski

Patients with multiple sclerosis most often pay attention to gait with a broad base with deteriorating balance when initiating locomotion or changing direction. The use of the stochastic resonance method enforces mechanical vibrations, which are characterized by the variability of rhythm, amplitude and direction of vibrations, which enforces postural adjustment regulated by the CNS (Central Nervous System) analysis and response to stimuli that disturb the body’s balance.
