Pesticides in the United States are frequently used to control pests in many settings from residential homes to agricultural crops. Most pesticides, when used in accordance with their manufacturer's label are relatively safe, and will naturally degrade once exposed to the environment, however, these natural degradative processes can be hindered when introduced indoors. Furthermore, it has been shown that pesticides can easily bond to surface dislodgeable residues (SDRs) commonly known as dust. There are various methods that can be used to characterize the presence and exposure of pesticides indoors. Wipe sampling is one of the important methods commonly used to measure pesticides on surfaces due to its simple and inexpensive nature, however, several methods exist for wipe sampling and each method has varying steps involving different wiping material, pre-treatment of wipes, wetting solvent, surface type, collection pattern, and storage.
The purpose of this literature review is to summarize concisely the methods from eighteen recent studies that used surface wipes to sample for pesticides from indoor environments. This report details the methods applied to perform the literature review, provide general wipe sampling information from government agencies, discuss other related surface sampling methods, provide a brief summary of wipe sampling methods applied in each study, and compare the methods applied to provide considerations for those seeking to use surface wipes for sampling pesticides.
Overall, it would seem that there are more variations than similarities between wipe sampling methods from the literature reviewed. Similarities included the use of isopropyl alcohol (IPA) as the wetting solvent and how wipe samples were stored after collection. The differences in wiping materials, pre-treatment of wipes, surface types, and collection patterns still demonstrate the need for a standardized method. Until a standardized method is established, poor comparisons of study results will continue and knowledge gaps will remain.
