“…Generally, the results of this consecutive‐year monitoring suggested that PCP contamination in the studied foods from retail outlets in GD generally declined over the study years because of its restricted use in industry and prohibition in cultivation and aquaculture (Ge et al., 2007; Hong et al., 2005; Xiao et al., 2012; Zheng et al., 2011).…”

“…PCP and its sodium salt (Na‐PCP) are commonly used as bactericides, fungicides, herbicides, algaecides, defoliants, and wood preservatives (Ge et al., 2007; Gulcan et al., 2008; Hilton et al., 1970; Lamparski et al., 1978; Li et al., 2012; Piskorska‐Pliszczynska et al., 2016; Ryan et al., 1985; Tang et al., 2007; Xiao et al., 2012; Zheng et al., 2011; Zhou et al., 2017). In particular, they were extensively sprayed in the aquatic system in southern China from the early 1960s to the early 1990s to kill snails, which are the intermediate hosts of schistosomes, for schistosomiasis control (Hong et al., 2005; Tang et al., 2007; Xiao et al., 2012; Zheng et al., 2012; Zhou et al., 2017). Consequently, PCP and its derivatives have caused serious and extensive contamination of environmental media in China, especially the sediment, due to the lack of degradation in deposits.…”

As a persistent organic pollutant, pentachlorophenol (PCP) has serious impacts on human health. However, its presence in animal source food products sold in the Guangdong Province (GD) of China, and the resultant dietary exposure have not been elucidated. To address this gap, 3,100 samples from seven food categories, including beef, pork, mutton, offals, broilers, hen eggs, and farmed freshwater fish, marketed throughout four geographical regions of GD, were collected from 2015 to 2018. Gas chromatography coupled with mass spectrometry was employed to detect PCP levels in these food matrices. PCP was found in all food categories, but the average contamination levels were low, ranging from 0.40 µg/kg wet weight (ww) (hen eggs) to 5.85 µg/kg ww (offals). However, higher concentrations of PCP were detected (P < 0.05) in animal source food from the North region. Additionally, a temporal declining trend was observed in this four‐year consecutive survey. The estimated human dietary exposure of PCP to population groups, including the general population and subgroups (male and female, children, and adults), was found to be far below the permissible daily intake (3 µg/kg body weight). Therefore, the health impacts of PCP should be correspondingly low for local residents, based on current toxicological knowledge. Regional exposure patterns varied due to different extents of contamination in the four areas, and pork, broilers, and freshwater fish were the major sources of dietary PCP exposure. Practical Application As a persistent organic pollutant, pentachlorophenol (PCP) has serious impacts on human health. However, its presence in animal source food products sold in Guangdong Province of China, and the resultant dietary exposure have not been elucidated. In this study, we conducted an in‐depth investigation on the occurrence of PCP in major foodstuff categories, including beef, pork, mutton, broilers, offals, hen eggs, and farmed freshwater fish, marketed in all 21 prefecture‐level divisions of Guangdong Province, in order to provide integral insights for regulatory authorities.

Japanese schistosomiasis was endemic in Dongting Lake, the second largest freshwater lake in China. The technical sodium pentachlorophenate (Na-PCP) was widely used during the period between the early 1960s and early 1990s to kill oncomelania, the intermediate host of Schistosomes. However, polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) also contaminated the environment of Dongting Lake due to trace impurities of Na-PCP. In this study, 13 species of freshwater fish were collected from Dongting Lake and analyzed in wet and dry seasons. Temporal (wet and dry season) variations in PCDD/Fs in fishes from Dongting Lake were observed. The concentration of PCDD/Fs was considerably higher in the wet season than in the dry season and in areas in China where Na-PCP was not applied. The higher level of PCDD/Fs in the wet season may be attributed to the use of Na-PCP in the past and to the increase in the migration of PCDD/Fs from sediments to water in the wet season. The results indicate that the risk of PCDD/Fs contamination is connected with prior consumption of fishes that live in the Na-PCP application area. However, there was no difference in the concentrations of polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) between the wet and dry seasons.
