“…In various wood samples, PCP has been most commonly determined by solvent extraction and chromatographic analysis [ 17 , 38 , 44 , 45 , 46 , 47 , 48 , 49 , 50 ], resulting in low detection limits due to preconcentration. Such methods are destructive, but have been used on wooden art objects in Belgium [ 51 ] and Germany [ 22 ], where small fragments were removed for analysis.…”

Non-Destructive Detection of Pentachlorophenol Residues in Historical Wooden Objects

Wood is a natural polymeric material that is an important constituent of many heritage collections. Because of its susceptibility to biodegradation, it is often chemically treated with substances that can be harmful to human health. One of the most widely used wood preservatives was pentachlorophenol (PCP), which is still present in museum objects today, although its use has been restricted for about forty years. The development of non-destructive methods for its determination, suitable for the analysis of valuable objects, is therefore of great importance. In this work, two non-destructive solid-phase microextraction (SPME) methods were developed and optimized, using either headspace or contact mode. They were compared with a destructive solvent extraction method and found to be suitable for quantification in the range of 7.5 to 75 mg PCP/kg wood at room temperature. The developed semi-quantitative methods were applied in the wooden furniture depot of National Museum of Slovenia. PCP was detected inside two furniture objects using headspace mode. The pesticide lindane was also detected in one object. The indoor air of the depot with furniture was also sampled with HS SPME, and traces of PCP were found. According to the results, SPME methods are suitable for the detection of PCP residues in museum objects and in the environment.

“…Currently, PCP detection and quantification methods include gas chromatography (GC), high performance liquid chromatography (HPLC) and gas chromatography-mass spectrometry (GC-MS) (Bartelt et al 1998;Crespin et al 1999;Oubina et al 1997;Crespyn et al 2002). However, few studies were conducted to quantify PCP in vitro using the aryl hydrocarbon receptor (AhR) and fluorescent quantitative PCR (qPCR) technique.…”

Developing a qPCR method to quantify AhR–PCP–DNA complex for detection of environmental trace-level PCP

Pentachlorophenol (PCP), a widely-used aseptic or biocide, is known as an environmental toxicant involved in endocrine disruption even at a trace level. In order to reliably and efficiently quantify environmental trace-quantity PCP, this study developed a novel PCP detection method using the aryl hydrocarbon receptor (AhR) and fluorescence quantitative PCR (qPCR). DNA probe with AhR binding sites was synthesized by PCR before added into AhR-PCP complex. After AhR-PCP-DNA complex was digested with exonuclease, copy number of DNA probe was determined using fluorescence qPCR. To calculate PCP concentration in samples, a standard curve (PCP concentration versus Ct value) was constructed and the detection range was 10(-13) to 10(-9) M. PCP detection limit was 0.0089 ppt for the AhR-PCP-DNA complex assay and 8.8780 ppm for high performance liquid chromatography, demonstrating that the method developed in this study is more sensitive. These results suggest that AhR-PCP-DNA complex method may be successfully applicable in detection and quantification of environmental trace-level PCP.

“…Recently, various alternative methods for the determination of PCP in wood were proposed. With many of them, such as the Curie-point pyrolyzer, 5 FT-IR spectroscopy, 6 or the photon activation analysis, 7 on-site use is not possible. Detection of PCP with mobile GC-MS, GC-ECD, or ion mobility spectrometry 8 still requires the homogenization of the wood sample, being both a time-consuming and destructive procedure.…”

“…The determination of PCP in wood is conventionally done by using expendable and time-consuming wet-chemical procedures. Usually the wood is homogenized before PCP is extracted from the matrix with organic solvents or supercritical fluid extraction and detected by gas chromatography (GC) coupled with mass selective (MS) or electron capture detectors (ECD). − These technical laboratory procedures are indeed very sensitive, but they are time-consuming, expensive, and can only be handled by trained workers in well-equipped analytical laboratories.…”

The still-remaining high amounts of pentachlorophenol (PCP), used as wood preservative, in buildings and in waste wood are a potential risk for humans and the environment. To ensure a fast and selective measurement of PCP, a screening tool was developed, which is not only sensitive, but, unlike conventional methods, it requires no added chemicals, is simple, cost-effective, mobile, and capable of on-site operation. The instrument combines light-induced thermodesorption sampling followed by an external cavity diode laser based photoacoustic detector. Measurements on wood samples proved that the system can determine PCP to as low as a concentration of 10 microg/cm2 within minutes without destruction of the sample. The system was calibrated with reference to the concentration of PCP impregnated on the wood surface. It is demonstrated that measurements are not influenced by moisture content of the wood samples.
