Sensors2002, 2(9), 374-382;https://doi.org/10.3390/s20900374

23 September 2002

Benzene is a carcinogen with a maximum permitted exposure limit in the atmosphere of 16.25μg m-3 (5 ppb). There is a need for an inexpensive instrument for measuring benzene concentrations, particularly in urban areas. We have shown that thin films o...
