“…In a specific case, Sonne et al (2014) reported that PCBs could be the reason for vitamin D metabolism changes in Greenland sled dogs. Because of their potential health effects and possible biosentinel capacity for human exposure, the systematic monitoring of OCPs and PCBs in domestic cats and dogs is essential (Backer et al, 2001; Braouezec et al, 2016; Brits et al, 2018; Dirtu et al, 2013; Dorne and Fink-Gremmels, 2013; Gonzalez-Gomez et al, 2018; Norrgran Engdahl et al, 2017; Ruiz-Suárez et al, 2016; Severe et al, 2015; Storelli et al, 2009).…”

“…Pet animals live in the same environments as humans and are exposed to the same pollutants and generally through the same routes. Therefore, many studies have suggested that wild and domestic animals are sensitive indicators of environmental pollutants and public health hazards (Gonzalez-Gomez et al, 2018; O’Brien et al, 1993; Reif, 2011). Ali et al (2013) performed the first study of organohalogenated contaminants in the serum and hair samples of cats and dogs and compared them with human serum in the same region in Pakistan.…”

“…Also, the exposure of companion animals to some chemicals may be even higher than in humans. It has been reported that pets respond to POPs and other toxic chemicals in the same ways as humans (Ali et al, 2013; Brits et al, 2018; Gonzalez-Gomez et al, 2018; Norrgran Engdahl et al, 2017; O’Brien et al, 1993). However, some researchers reported that the sentinel capacity of household pets is questionable.…”

“…Because, plasma levels of OCPs and PCBs are generally observed lower than humans, pet animals have higher metabolizing capacity of chlorinated pollutants and formulations of pet and human foods are very different (Kunisue and Tanabe, 2009; Ruiz-Suárez et al, 2015, 2016). Despite the different claims, because of their high prevalence and potential health effects, OCPs and PCBs should be monitored periodically (Ali et al, 2013; Backer et al, 2001; Gonzalez-Gomez et al, 2018; Reif, 2011).…”

The aim of this study was the determination of plasma concentrations of organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) in cats and dogs and evaluation of their prevalence and possible effects. The concentrations of nine OCPs, such as α-hexachlorocyclohexane (HCH), β-HCH, γ-HCH, hexachlorobenzene (HCB), aldrin, 2,4'-dichlorodiphenyltrichloroethane (2,4'-DDT), 4,4'-DDT, 2,4'-dichlorodiphenyldichloroethylene (2,4'-DDE) and 4,4'-DDE and 16 PCBs (PCB-28, -52, -70, -74, -81, -99, -101, -118, -138, -153, -156, -170, -180, -183, -187 and -208) were evaluated in the plasma samples of pet cats ( n = 15) and dogs ( n = 21). The concentrations of OCPs ranged from 1.12 ng g lipid weight (lw) to 7.65 ng g lw in cats and from 1.25 ng g lw to 6.79 ng g lw in dogs. In addition, mean PCB levels were 0.58-5.66 and 0.52-6.62 ng g lw in cats and dogs, respectively. β-HCH, γ-HCH and PCB-138 levels were significantly higher in dogs ( p < 0.05). As far as could be determined, OCPs and PCBs were detected in the plasma samples of domestic cats and dogs in Turkey for the first time. Their concentrations were similar to those reported in earlier studies abroad. However, in contrast to other research, the levels of some OCPs were higher in dogs than in cats. It is concluded that, because of their high prevalence and potential health effects in animals and humans, OCP and PCB levels should be monitored systematically in domestic cats and dogs.

“…OPFR concentrations have been reported in indoor air, dust and wipe test samples from electronic equipment and window protection film (Cao et al, 2019;Brandsma et al, 2014;Stapleton et al, 2011Stapleton et al, , 2009Vykoukalov a et al, 2017). OPFR levels have also recently been reported in dog hair (Gonz alez-G omez et al, 2018). Generally, OPFRs in dust from homes and other indoor environments are dominated by tris(2-butoxyethyl) phosphate (TBOEP), followed by the chlorinated OPFRs (Wei et al, 2015).…”

Flame retardants (FRs), such as brominated flame retardants (BFRs) and organophosphorus flame retardants (OPFRs), are diverse groups of compounds used in various products related to the indoor environment. In this study concentrations of eight polybrominated diphenyl ethers (PBDEs), two alternative BFRs and ten OPFRs were determined in indoor dust (n ¼ 20) and pet cat hair (n ¼ 11) from South Africa. The OPFRs were the major FRs, contributing to more than 97% of the total FR concentration. The median Ʃ 10 OPFRs concentrations were 44,800 ng/g in freshly collected dust (F-dust), 19,800 ng/g in the dust collected from vacuum cleaner bags (V-dust), and 865 ng/g in cat hair (C-hair). Tris(1-chloro-2propyl) phosphate (TCIPP) was the dominant OPFR in the dust samples with median concentrations of 7,010 ng/g in F-dust and 3,590 ng/g in V-dust. Tris(2-butoxyethyl) phosphate (TBOEP) was the dominant OPFR in Chair , with a median concentration of 387 ng/g. The concentrations of Ʃ 8 PBDEs were higher in F-dust than in V-dust. BDE209 was the dominant BFR in all three matrices. Bis(2-ethylhexyl)-3,4,5,6tetrabromo-phthalate (BEH-TEBP) and 2-ethylhexyl-2,3,4,5-tetrabromobenzoate (EH-TBB) showed notable contributions to the BFR profile in cat hair. A worst-case dust exposure estimation was performed for all analytes. The estimated TCIPP daily intake through dust ingestion was up to 1,240 ng/kg bw for toddlers. The results indicate that OPFRs are ubiquitous in South African indoor environment. Indoor dust is a major source of human exposure to environmental contaminants. This can for example occur through hand-to-mouth contact of toddlers, and is an important route of exposure to currently used FRs accumulated on dust particles. The presence of FRs, in particular high concentrations of OPFRs, suggests that children and indoor pet cats may have greater exposure to FRs than adults.

Pets as Sentinels of Human Exposure to Neurotoxic Metals

Pets as Sentinels, Forecasters and Promoters of Human Health

View full text Add to dashboard Cite

The idea that animals may be used as sentinels of environmental hazards pending over humans and the associated public health implications is not a new one. Nowadays pets are being used as bioindicators for the effects of environmental contaminants in human populations. This is of paramount importance due to the large increase in the worldwide distribution of synthetic chemicals, particularly in the built environment. Companion animals share the habitat with humans being simultaneously exposed to and suffering the same disease spectrum as their masters. Moreover, their shorter latency periods (due to briefer lifespans) enable them to act as early warning systems, allowing timely public health interventions. The rise on ethical constraints on the use of animals and, consequently, on the sampling they can be subjected to has led to the preferential use of noninvasive matrices, and in this case we are looking into hair. This chapter focuses in three non-essential metals: mercury, lead, and cadmium, due to their ubiquitous presence in the built environment and their ability of affecting the mammal nervous system. There is a fairly short amount of studies reporting the concentrations of these metals in pets' hair, particularly for cats. These studies are characterized, and the metal concentrations corresponding to different parameters (e.g., age, sex, diet, rearing) are described in order to provide the reader with a general vision on the use of this noninvasive matrix on the studies conducted since the last two decades of the twentieth century.
