“…Free-ranging avian species are one of the most significant indicators for assessing the quality of environmental pollution and are non-targeted victims as they are frequently exposed to different contaminants in various directions [7,8]. In India, very little research has been done regarding pollutants and their effects on wild birds [2,15,16].…”

Massive quantities of unadvisable synthetic pesticides are used in modern agricultural industries in order to increase productivity to convene food demands. Wild birds are an excellent bio-indicator of environmental contaminations as pesticides and heavy metals are intentionally highly hazardous pollutants. Considerably, raptorial birds (owls) attract consumers in the food chain and food web because they have wider forager and foraging grounds. In the current investigation, owl pellets were used as a viable tool and novel approach to detecting environmental contaminants. In total, 30 pellets comprising five species were collected from selected farmlands, and 11 metals (Cr, Mn, Co, Mo, Se, V, Cu, Ni, Pb, Zn, and Fe) were analyzed using inductively coupled plasma mass spectrometry (ICP-MS). Undeniably, the Brown Fish Owl showed more metal accumulation than the Barn Owl, Spotted Owl, Indian Eagle Owl, and Mottled Wood Owl. Among the species, the levels of metals such as Manganese (Mn), Molybdenum (Mo), Vanadium (V), Copper (Cu) and Zinc (Zn) varied significantly (p < 0.05). Nonetheless, the research revealed that the agroecosystem was contaminated with heavy metals. The present outcome highlights that the management of the environment, especially the agroecosystem, must be examined with a careful assessment of contaminants, and it is a vital resource for human and other related wildlife faunal communities.

“…Considerably, owls are peak and predominant consumers in the food web, and have substantial foraging grounds. It is anticipated they will accumulate a higher concentration of toxic materials (pesticides and heavy metals) as they are present in the foraging grounds [7].…”

“…In contrast, developed nations such as Europe or USA (3 kg/ha) or other Asian countries like China, South Korea, Taiwan, and Japan have more than 10 kg/ha consumption (Abhilash & Singh, 2009 ; De et al, 2014 ). Despite India's low per-hectare pesticide consumption, widespread pesticide contamination in food commodities (Arisekar et al, 2019 ; Bakore et al, 2004 ; Prakash et al, 2004 ; Samidurai et al, 2019 ; Sharma, 2021 ), soil (Agnihotri et al, 1996 ; Devi et al, 2015 ; Joseph et al, 2020 ; Singh et al, 2007 ), and water (Duttagupta et al, 2020 ; Kurakalva & Aradhi, 2020 ; Lari et al, 2014 ) have been identified. Between 2010 and 2015, pesticide use in India increased by around 50% (Bose et al, 2021 ).…”

Chemical pesticides in the hydrogeological system are a global concern as they pose a severe threat to humans and other organisms. In agriculture, around 4.12 million tonnes of pesticides were used globally in 2018, which is 50% more than in the 1990s. Various pesticides detected in the hydrogeological system of India since the 1990s have been documented and reviewed to understand the prevalence, source, history and degradation pathways. This review contributes to a better understanding of existing pesticide pollution and the state of hydrogeological resource deterioration. Small to excess levels of pesticide residues were detected in groundwater, surface water, soil, and sediments. Pesticides that were most commonly and predominantly found in the hydrogeological system were HCHs, DDTs, endosulfan, heptachlor, drins (aldrin, dieldrin, endrin), chlordane etc. β and γ-HCH isomers among HCHs, whereas p,p ′-DDT and p,p ′ - DDE among the DDTs were detected most prevalently. In many regions, pesticide residue levels in water have exceeded the maximum residue limits of WHO and BIS, while those in soils and sediments have exceeded the threshold effect level and probable effect level. Higher pesticide residues were detected in the water resources of rural agricultural areas compared to peri-urban or urban areas. A positive correlation of pesticide residues between water resources and soil has been observed in some regions, suggesting a similar contamination source. Diagnostic ratios of pesticides reveal their source, history and degradation pathways. Diagnostic ratios observed in various studies conducted in India suggest historical as well as recent use of banned pesticides. Strengthening current policies and regulations, monitoring pesticide use, changes in pesticide application practices, awareness among farmers, and the use of prominent removal techniques are necessary to tackle pesticide contamination in India.

“…In addition, coastal cities in these states house various heavy industries with the prevalence of harbor activities in their estuarine regions. Impacts on environment and public health associated with pesticide usage has been widely reported from Kerala ( Khuman et al, 2020 , Tholkappian and Rajendran, 2011 ) and Tamil Nadu ( Jeyakumar et al, 2014 , Rajendran et al, 2005 , Samidurai et al, 2019 , Srimurali et al, 2015 ).…”
