To test your work area for naphthalene, you can use a portable gas detector that is capable of detecting naphthalene vapors. You can purchase or rent a gas detector from a reliable supplier. Make sure to follow the instructions on how to use the gas detector properly.
To determine the amount of naphthalene in your body, you can undergo a blood, urine or breath test. These tests can detect the presence of naphthalene in your system and the results can indicate how much of the substance is in you. If you suspect that you have been exposed to naphthalene, you should seek medical attention immediately.<|im_end|>
