BENZENE - MEASUREMENT OF PPB LEVELS ACCURATELY IN REAL TIME

摘要

Exposure to benzene has been shown to cause bone marrow damage which can lead to acute myeloid leukaemia (AML). There is also evidence that exposure to benzene can cause damage to the reproductive organs. Many techniques have been used to measure total hydrocarbon levels, measurement of benzene against a background of other BTEX gases is much more difficult. This difficulty in measurement has meant there has been a reluctance to reduce allowable levels of benzene in the atmosphere. The current long and short term exposure levels can be seen as a direct result of the lack of simple to use techniques capable of accurately measuring lower concentration levels.
