Determination of plasma concentrations of organochlorine pesticides and polychlorinated biphenyls in pet cats and dogs

Abstract

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.

“…In the case of gender, there was no difference between females and males, except total OCPs and total PAHs. This result was similar to that reported in our previous study performed on cats and dogs (Yavuz et al., 2018).…”

“…In addition, all PCBs were detected in dog plasma samples (0.52–6.62 ng/g lipid), and 10 of 16 PCBs were detected in cats (0.58–5.66 ng/g lipid). These results were similar to those reported in previous studies performed on cats and dogs in different countries, such as Pakistan, France, UK, Spain and Japan (Yavuz et al., 2018).

“…In the case of gender, there was no difference between females and males, except total OCPs and total PAHs. This result was similar to that (Yavuz et al, 2018). could be a causative factor in several disorders, such as cancer, metabolic disorders, immune suppression, growth failures, cardiovascular diseases, and congenital deformities in humans and animals, even at very low concentrations.…”

Pets, Genuine Tools of Environmental Pollutant Detection

“…In contrast to other results in which levels of organochlorine pesticides in plasma (OCP) were higher in cats, the results of the study conducted by Yavuz et al [198] in 15 cats and 21 dogs revealed much higher levels of OCP (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 among canine companions.…”

“…Hexachlorobenzene is a long-lived organochlorine compound the benzene ring of which is a closed conjugated system (Yavuz et al, 2018), making chlorine difficult to replace. The more substituted chlorine is, the greater its toxicity and resistance to degradation will be.…”
