Only one wipe sample, taken from a baking sheet in the SC laboratory where treated plant material was dried, had a detectable level of AB-PINACA.
Wipe samples were collected from floors, interior window sills, ductwork, furniture, and appliances using the American Society for Testing and Materials (ASTM) D 6480-05 procedures, "Wipe Sampling for Settled Asbestos" (ASTM, 2010) and analyzed by TEM by the independent laboratory.
To further analyze these results, a graph of the surface-lead concentrations (wipe sample measures) versus direct lead-paint concentrations (XRF measures) from these studies was plotted (Figure 1).
For wipe samples, the solvent used in the wipe sample and the method of extraction may also influence the comparability of results.
To investigate the relationship between the hand samples and wipe samples, the mean of the geometric means of the two wipe sample locations for each home for every sampling date was taken and the ratio of this value to the mean of the geometric means of the hand sample locations for each home was calculated (Table 4).
The descriptive statistics for all LWW wipe sample data collected at baseline are given in Table 1.
Surface wipe samples were collected within treated rooms on days -1, 1, 2, 3, 5, 7, 9, and/or 11 from nontargeted surfaces (i.e., areas not directly sprayed with the pesticide).
Investigators took wipe samples weekly for four weeks by wiping the entire area with a laboratory wipe.
The 2001 formative data collection took place in the participants' home when at least one child in the target age range was present and consisted of an interviewer-administered questionnaire of fixed-response and open-ended questions, collection of wipe samples, and observations of the residence and neighborhood.
OEH staff then took a dust wipe sample from the miniblinds to determine if lead found on the surface of the plastic slats could be easily removed and ingested via the child's hand-to-mouth behavior.
Recovery of chlorfenvinphos generally ranged from 75 to 150%, suggesting that each wipe sample was extracted well.
In addition to the floor wipes, one wipe sample was taken from an outside wall in Whitney Pier (outside NOCO) facing the steel plant site.
