PAHs appear to be the critical exposure for IUGR, but PAHs were not measured by the national monitoring system used for exposure estimation by Bobak (2000).
The continuous monitoring system for dust exposure has shown that the concentrations of chromium-containing dusts in the workplace air decreased at a rate of 17% from 1970 to the early 1990s in the mine, the ferrochromium works and the stainless steel melting shop.
The lack of a proper air quality monitoring system to track human exposure is a major limitation.
The extent of esophageal acid exposure was determined using the ambulatory Digitrapper MK III pH monitoring system (Synectic Medical, LTD, Sweden).
For all these reasons, with the aim of identifying and quantifying the environmental exposure, Blickling Hall was monitored between August 2012 and October 2014 using an extensive monitoring system, which is described in detail below.
The passive sampler we employed for the determination of NO2 exposure was simple, did not restrict daily activities and exhibited a good correlation with the state monitoring system.
Geographic information systems and sensor-based technologies will enable greater precision in environmental and personal exposure monitoring, integrating previously unavailable data into research.
In most developing countries, where proper drug monitoring system during pregnancy does not exist, it is difficult to know the magnitude of drug exposure in pregnancy.
To estimate potential exposure to Cd from vehicle emissions, we obtained traffic count data for 2000 from the California Highway Performance and Monitoring System (California Department of Transportation 2007).
A solid monitoring system is essential.
