“…Although the penetration of rodenticides into the trophic chain is a known fact (Plaza et al, 2019;Ruiz-Suarez et al, 2014;Sanchez-Barbudo et al, 2012;Seljetun et al, 2019), it is still surprising that residues of at least one of these compounds have been found in almost 15% of the birds in this series. More than one compound was found in 8 of the individuals (from 2 to 4 compounds).…”

“…If we take as a reference the list of substances included in the monitoring programs for residues in food for human consumption, at least 200 chemicals should be considered as worrisome in the European Union (EC, 2019a). Unfortunately, the excessive use of these agricultural pesticides causes their penetration into ecosystems and can compromise the health and even survival of many biological species (Encarnacao et al, 2019;Klich et al, 2020;Krief et al, 2017;Plaza et al, 2019). Also, deliberate abuse of pesticides to poison wildlife occurs throughout the world (Bille et al, 2016;Fajardo et al, 2012;Hernandez and Margalida, 2008;Motas-Guzman et al, 2003;Ntemiri et al, 2018;Ogada, 2014;Ruiz-Suarez et al, 2015).…”

• Validation of a method for the simultaneous quantification of 360 toxic chemicals in whole blood • One-step acetate buffered micro QuEChERS using acidified acetonitrile yielded recoveries N70%. • Only 250 μl of sample and quantification at the sub-ppb level makes it suitable for biomonitoring. • Verified in a series of 36 barn owls and 112 common kestrels, which test positive for 3-25 pollutants

“…, 2017a, 2017b, Plaza et al . 2019). In this sense, further research should evaluate how microorganisms affect the different age classes of vultures and whether they can be transmitted vertically (through the egg), producing reproductive failure, especially in order to understand effects on the demographic rates and population dynamics of threatened vulture species.…”

The effects that microorganisms (bacteria, viruses and fungi) have on their hosts remain unexplored for most vulture species. This is especially relevant for vultures, as their diet consists of carcasses in various stages of decomposition, which are breeding grounds for potentially pathogenic microorganisms. Here we review current knowledge of bacterial, viral and mycotic microorganisms present in wild vultures. We consider their potential to cause disease in vultures and whether this poses any population‐level threats. Furthermore, we address the question of whether vultures may act as disease spreaders or mitigators. We found 76 articles concerning bacterial, viral and mycotic microorganisms present in 13 vulture species, 57 evaluating bacteria, 13 evaluating viruses and six evaluating mycotic microorganisms. These studies come from all continents where vultures are present, but mainly from Europe and North America, and the most studied species was the Griffon Vulture Gyps fulvus. We found that vultures are colonized by zoonotic pathogens, and even host‐specific human pathogens. Some recorded bacteria showed multi‐antibiotic resistance, especially those that can be associated with anthropogenic food subsides such as supplementary feeding stations. We found evidence that vulture health can be affected by some microorganisms, producing a wide array of clinical alterations that have the potential to influence mortality risk and fitness. We did not find clear scientific evidence that vultures play an epidemiological role spreading microorganisms to humans and other species. However, there is evidence that vultures could prevent the spread of infectious diseases through their removal of decomposing organic material. The evaluation of vulture exposure to microorganisms is of fundamental importance to design better conservation policies for this threatened group, which may serve a key role as ecosystem cleaners.

Agriculture residues and domestic effluents are contaminants that reach aquatic ecosystems leading to toxic effects to environment and human health. These contaminants impacting mainly developing countries, due to precarious treatment of effluents and lack of legislation in the use of pesticides. Perequê River (South of Brazil) is impacted by pesticides (mainly glyphosate) and domestic effluents. The aims of this study were to analyze the concentration of glyphosate in water and sediments of Perequê River; and to evaluate the sublethal effects of the river contamination in Astyanax altiparanae using biomarkers. A sampling of water, sediment and fish were carried out in Perequê River (November/2016). The samples were collected in two sites, site 1 (S1) that is located on agriculture area and water catchment point; and site 2 (S2) located on the area with a domestic effluents influence. Water and sediment samples were used to glyphosate quantification. Fish were collected and tissues (brain, muscle, liver) were used to biochemical and genetic biomarkers. Glyphosate were quantified in S1, which is impacted by agriculture. Alterations in the liver biomarkers were not observed between the sites. However, the decrease in the AChE activity was observed in the S2, showing that the mixture of contaminants (urban and agriculture contaminants) can lead to anticholinesterasic effects. The sublethal effects observed can be a threat of environmental and human health.
