What type of sampling method is used to obtain precise measurements of a worker's exposure to air contaminants?

1. General survey sampling

2. Personal sampling

3. Environmental quality sampling

4. Fixed-location sampling

The correct answer is: Personal sampling

Personal sampling is the most appropriate method for obtaining precise measurements of a worker's exposure to air contaminants. This method involves collecting samples of the air that the worker is directly exposed to, typically through the use of personal air sampling pumps and filters. This allows for accurate and specific measurement of an individual's exposure levels. Option A, general survey sampling, involves taking a sample from a random selection of the population and may not accurately reflect the exposure levels of a specific worker. Option C, environmental quality sampling, may provide information about the overall air quality in a specific area, but does not specifically measure an individual's exposure. Option D, fixed-location sampling, only measures air contaminants at a specific location and may not accurately reflect the levels that a worker is exposed to throughout their day.
