Sustainable sampling of native bromeliads for environmental monitoring

By analysing the leaves of bromeliads, the availability of chemical elements in the atmosphere can be assessed. However, sampling steps affect the reliability of using such plants for environmental quality studies. This paper describes a novel and sustainable sampling methodology for conservation units, in which small discs (6 mm diameter) of bromeliad leaves could be taken without removing ...

Area Monitoring: Diffusion Sampling

Indoor and outdoor gas hazards that exist in open areas are usually monitored using diffusion-type sensors. A diffusion sensor has no active sample-drawing system; diffusion sensors rely on the ambient air movement and pressure to deliver the sample to the sensing element. Diffusion-type sensors are a reliable and cost-effective way to monitor open area gas hazards. When installing diffusion ...

Table of Statistical Corrections According to Feller for the BioCapt® Microbial Impactor in Microbial Air Sampling

Abstract This application note uses the principle that, as the number of viable particles — colony forming units (CFUs) — impact on an agar plate increases, the probability that viable particles will enter unoccupied space decreases. The values within Tables 1 and 2 are shown at flow rates of 25–50 LPM and 100 LPM. BioCapt microbial impactors are used on all Particle ...
