ppb

the ppb level in the water was surprisingly high.

we need to measure the ppb of nitrogen in the soil.

the ppb concentration of the contaminant was below the limit.

the analysis showed a significant increase in ppb values.

ensure the ppb readings are accurate and consistent.

the ppb standard for drinking water is strictly enforced.

we are monitoring ppb levels daily for quality control.

the ppb detector provides precise measurements.

the ppb range was determined by laboratory testing.

the ppb threshold was exceeded in several samples.

the ppb data was compiled into a comprehensive report.
