This Chapter provides broad review on emission testing of new and in-use vehicles, particularly in the United States. Under a mandate from the U.S. Congress, the U.S. Environmental Protection Agency (US EPA or EPA) sets emissions standards for vehicles. All of EPA's emission regulations ...
A DriveOn Emissions Inspection, is your fleet’s environmental report card. It’s a test performed on a vehicle’s engine to determine the volume and type of pollutants it’s emitting. The process involves measuring the amount of pollutants released from the exhaust pipe when the vehicle is ...
These studies indicate that increased attention should be given to ongoing blood serum testing to estimate population exposure to PFAS. Also critical is the transfer of PFAS from mother to child during the nursing period. Fromme et al. determined a median value of 40 pg/mL breast milk for ...

Telecommunication workers who spend time at a short distance from the active equipment, for the purposes of testing, maintenance, installation, etcetera, may be at risk of much greater exposure than the general population. Many times base stations are not turned off during maintenance, but the po...
The same testing procedure for each mobile service was repeated five times at different times of the day and on different days. We found small variations in terms of the service data and signaling traffic, the power consumption of the 4G connection and CPU, and the 4G signaling duration. Comp...
