Two different types of passive samplers were compared:XAD-2 resin and carbon-based foam.The results show that active and passive sampling gives comparable results for the sampling of atmosphericpesticides.
📌 3 Key Takeaways
🎯
Objective & Hypothesis:Passive and active samplers were compared for the monitoring of pesticides in the atmosphere during fieldcampaigns undertaken in Alsace (northeastern France).
📊
Key Findings & Data:Two different types of passive samplers were compared:XAD-2 resin and carbon-based foam.The results show that active and passive sampling gives comparable results for the sampling of atmosphericpesticides.
💡
Conclusion & Impact:It is assumed that passive sampling could be used as a low-cost and simple alternative due to thenumber and quantities of pesticides detected, and the use of carbon-based foam as a passive sampler permits thedetection of more molecules than those detected by the XAD®-2 resin, which remains the most efficient samplerfor adsorbing more volatile pesticides, mecoprop-p, carbendazim, fluroxypyr, and isoproturon, among others.Thus, NMC@SiC was found to be a better adsorbent than XAD®-2 resin for the collection of a wide range ofpesticides in the air.The calculated sampling rates varied between 0.43 and 6.14 m3 d−1 for the XAD®-2 resin and between 0.08and 6.80 m3 d−1 for the NMC@SiC foam and are of the same order of magnitude and comparable to theliterature values.
