“…Of the 622 birds sampled, 469 were above 4 ppm; and 38/41 birds at site QS1, which had the highest Pb levels, were above this threshold. Our mean levels (17.1 ppm) were above all but one of 29 seabird studies reviewed by Vizuete et al (), and above all 4 species of raptor studied by Dauwe et al (). We hope that future studies will sample bird blood in our region because toxicity thresholds are better understood in blood than in feathers (Williams et al ).…”

Heavy metal pollution is widespread in China, particularly in its mining regions. Mercury (Hg) concentrations in birds from Guizhou Province were recently reported to be above adverse effect levels, even in nonmining areas. We sampled birds to investigate whether Hg might be a threat near lead (Pb), zinc (Zn), and tin (Sn) mines in Guangxi Zhuang Autonomous Region. We measured concentrations of 8 metals/metalloids in feathers of 627 resident birds representing 60 species sampled across 14 sites on 5 rivers. We found that Hg concentrations (mean ± standard deviation, 1.27 ± 2.02 ppm) were lower than in the recent Guizhou study. Mercury had the fewest correlations with other metals/metalloids; the mined metals (Pb, Sn, Zn) had the most such correlations. Levels of cadmium (Cd; 1.12 ± 2.64 ppm), arsenic (As; 4.78 ± 17.11 ppm), and Pb (17.18 ± 24.49 ppm) were closer to thresholds of adverse effects or relatively high compared to other studies. With the exception of a few hot spots for Hg, Cd, and As near mines, metal/metalloid levels were fairly evenly distributed among sites, consistent with the regional occurrence of mineable ore deposits. It appears that Hg is not threatening to all avian species in China, although it may be problematic for some species near Hg mines. In addition to Hg, however, other metals/metalloids may pose wildlife health hazards. Environ Toxicol Chem 2020;39:371-380.

“…The environment is exposed to different anthropogenic pollutants generated by industrial, domestic and agricultural activities, which increase the level of pollutants derived from natural sources (Richard et al., 2017; Vizuete, Pérez‐López, Míguez‐Santiyán, & Hernández‐Moreno, 2018). Metals such as arsenic (As), mercury (Hg), cadmium (Cd), copper (Cu), chromium (Cr), lead (Pb), iron (Fe), manganese (Mn) and zinc (Zn) do not degrade and these metals could easily accumulate throughout the trophic chain and persist in nature (Borchert, Leaphart, Bryan, & Beasley, 2019; Burger, Mizrahi, Tsipoura, Jeitner, & Gochfeld, 2018; Vizuete et al, 2018); at the same time, As, Cd, Pb and Hg have no established biological functions and are considered as contaminants (Hejna et al., 2018). The presence of HMs has been registered in tissues of wild birds (Bond & Robertson, 2015; Burger et al., 2018; Majidi, Bahramifar, & Ghasempouri, 2015; Sepúlveda & Gonzalez‐Acuña, 2014), including the Andean condor (Di Marzio et al., 2018; Plaza et al, 2019; Wiemeyer et al., 2017).…”

Genomic data reveal international lineages of critical priority Escherichia coli harbouring wide resistome in Andean condors (Vultur gryphus Linnaeus, 1758)

et al. 2020

Critical priority pathogens have globally disseminated beyond clinical settings, thereby threatening wildlife. Andean Condors (Vultur gryphus) are essential for ecosystem health and functioning, but their populations are globally near threatened and declining due to anthropogenic activities. During a microbiological and genomic surveillance study of critical priority antibiotic‐resistant pathogens, we identified pandemic lineages of multidrug‐resistant extended‐spectrum β‐lactamase (ESBL)‐producing Escherichia coli colonizing Andean Condors admitted at two wildlife rehabilitation centres in South America. Genomic analysis revealed the presence of genes encoding resistance to hospital and healthcare agents among international E. coli clones belonging to sequence types (STs) ST162, ST602, ST1196 and ST1485. In this regard, the resistome included genes conferring resistance to clinically important cephalosporins (i.e., CTX‐M‐14, CTX‐M‐55 and CTX‐M‐65 ESBL genes), heavy metals (arsenic, mercury, lead, cadmium, copper, silver), pesticides (glyphosate) and domestic/hospital disinfectants, suggesting a link with anthropogenic environmental pollution. On the other hand, the presence of virulence factors, including the astA gene associated with outbreak of childhood diarrhoea and extra‐intestinal disease in animals, was identified, whereas virulent behaviour was confirmed using the Galleria mellonella infection model. E. coli ST162, ST602, ST1196 and ST1485 have been previously identified in humans and food‐producing animals worldwide, indicating that a wide resistome could contribute to rapid adaptation and dissemination of these clones at the human–animal–environment interface. Therefore, these results highlight that Andean Condors have been colonized by critical priority pathogens, becoming potential environmental reservoirs and/or vectors for dissemination of virulent and antimicrobial‐resistant bacteria and/or their genes, in associated ecosystems and wildlife.

“…A contaminação gerada pelos metais pesados fez com que os governantes, refletindo anseios da sociedade, repensassem as leis ambientais para minimizar a exposição aos contaminantes, seja por processos naturais ou atividades antrópicas (Alipour, et al, 2016). O arsênio (As), cádmio (Cd), chumbo (Pb), cobre (Cu), cromo (Cr), ferro (Fe), manganês (Mn), mercúrio (Hg) e zinco (Zn) são metais que não se degradam no ambiente, dessa forma, acumulam-se ao longo da cadeia trófica permanecendo na natureza por mais tempo, com influência direta no habitat, na cadeia alimentar e em processos fisiológicos e migratórios de aves silvestres (Alipour, et al, 2016;Vizuete, et al, 2018).…”

O chumbo é um metal não essencial tóxico encontrado em diversas formas químicas, portanto, pode causar poluição atmosférica, terrestre e aquática. A principal fonte de chumbo se deve a ação antrópica, através da utilização de munições à base de chumbo, pesca, combustível, mineração, incineração de lixo e atividade industrial. O objetivo da presente revisão é demonstrar o conhecimento atual sobre as fontes de contaminação por chumbo, os sinais clínicos e lesões observadas em aves silvestres, diagnóstico e tratamento, impactos na biodiversidade e medidas de prevenção. Para a realização do estudo, foi utilizado pesquisa de artigos nas bases científicas PubMed, portal de periódicos CAPES, SciELO e Google Acadêmico, no recorte temporal de 2015 a 2020. A partir dos estudos elencados, observou-se que os animais são frequentemente encontrados com alterações subclínicas, clínicas ou mortos em seus habitats naturais. A literatura afirma que os efeitos do chumbo no organismo variam de acordo com a dose, tempo de exposição e via de intoxicação, logo, as consequências na saúde das aves silvestres são inúmeras. Concluiu-se que a substituição do chumbo por outros componentes, alterações em normativas e conscientização sobre seu descarte, resultam em ganhos na conservação da natureza e melhoria da biodiversidade.
