“…Chlorpyriphos, an OP, inhibits acetyl choline esterase enzyme in a way that has cross generational implications (Anway et al, 2005) and it severely affects birds (Mitra et al, 2011). In order to monitor the pesticide residue in birds, the metabolic studies are required not only to identify the primary metabolites but also their accumulation and distribution within the body (Katagi and Fujisawa, 2021). Eng et al (2017) have reported the impairment of migration ability in white-crowned sparrow, a seed eating bird, after exposure to low (10% LD 50 ) and high dose (25% LD 50 ) of chlorpyriphos.…”

The continuous use of pesticides to improve agriculture has not only affected the crop but also altered the food chain and worst affected the non-target organisms. Birds utilizing agricultural landscapes for feeding get exposed to these chemicals through ingestion of sprayed soils, treated granules or seeds and prey items. Raptors like owls are the most likely victims of pesticide exposure as they are at the top level of food chain. In present study, excreta samples of barn owl and spotted owlet were collected from three locations and tested for presence of pesticide residues using gas chromatography. The organophosphate residues of dichlorvos, monocrotophos, phorate, malathion, quinalphos, profenophos, ethion were not reported in excreta of both owl species but the residues of chlorpyriphos (0.037 ppm) were detected in spotted owlet samples collected from village Barnhara only. The pyrethroid residues cyhalothrin, permethrin, cypermethrin were also found to be absent or below detectable limit in samples collected from different locations. The feeding habits of birds attribute to the level of contamination in predatory birds. Although the level of chlorpyriphos residues excreted out from the body of spotted owlet does not reflect the actual level of exposure to this bird but gives an indication of their being at the risk of exposure in the environment.

“…242 Additionally, the metabolic bioactivation of pesticides into more reactive compounds is another cause of avian toxicity. According to Katagi et al 's reviewed data on the bioactivation of pesticides in avian species, 243 several bioactivation pathway of pesticides produce higher avian toxicity, as summarized in Fig. 28.…”

“…Pollution threatens wildlife species all around the globe through a diversity of effects. At high enough concentrations, chemical pollution can be acutely toxic, causing direct mortality (Katagi & Fujisawa, 2021). At sub-lethal levels, pollutants may cause physiological harm both individually (Dietz et al, 2019), and when interacting with one another.…”

Anthropogenic pollution may disrupt wildlife physiology and impact their behaviour and survival. Potentially compounding this threat are immunomodulatory properties of pollutants that increase susceptibility to, and ability to withstand, infection. Of particular concern is avian influenza virus (AIV), which in its low-pathogenic form is endemic in many wild bird populations, notably waterfowl and shorebirds, and in its high-pathogenic form poses a threat to wildlife, livestock and people. While many pollutants are known to have immunomodulative properties, little is known about how these pollutants affect AIV infection risk specifically. We examined the concentrations of per- and polyfluoroalkyl substances (PFASs), which are considered immunomodulatory, and assessed their influence on avian influenza infection status in three reservoir species, red-necked stint (Calidris ruficollis, n=121), pacific black duck (Anas superciliosa, n=57) and grey teal (Anas gracilis, n= 62). Using data on viral prevalence (cloacal/oropharyngeal swabs) and seroprevalence (AIV anti-nucleoprotein antibodies), we found no significant effect of PFASs pollution (total PFASs ranging from <0.01-1290 ng/g in red-necked stint, <0.01-600 ng/g in pacific black duck and 0.3-200 ng/g in grey teal) on infection status in any of our three species. This may be due to relatively low pollutant concentrations, but we cannot rule out the possibility of population culling through a synergy of pollution and infection stressors. We therefore recommend further studies on infection incidence in more polluted species.
