“…Chromium levels at Civic Square in Goiânia are similar to the ones obtained in Pakistan with falcon feathers (1.98 mg/kg dry weight) (Movalli 2000). However, higher chromium concentrations were found in a study by Connell et al (2002) with European White Herons in Hong Kong (0.9 mg/kg dry weight), and in a study with wild pigeons in South Carolina (0.63 mg/kg) (Burger et al 1997). Research with sparrowhawks (Accipiter nisus) in Belgium, which included the analysis of several feathers other than from the wing and tail, revealed average Cr concentrations varying from 1.42 to 3.56 mg/kg (Dauwe et al 2003).…”

“…Studies on feathers of other birds, such as those of wild pigeons in South Carolina (USA), reported on manganese levels ranging from 3.6 to 6.1 mg/kg (Burger et al 1997) and from 1.7 to 22.6 mg/kg dry weight in the European White Swaileh and Sansur (2006) Herons from Hong Kong (Connell et al 2002). Furthermore, analysis of external feathers on the wing and tail of sparrowhawks (A. nisus) from Belgium revealed average Mn concentrations from 7.28 to 9.62 mg/kg (Dauwe et al 2003).…”

This study quantifies metal concentrations in washed and unwashed feathers of feral pigeons (Columba livia). The material was collected in two different sites: Goiânia (capital of Goiás State), with high anthropic activities, and Jataí (a city in Goiás), with low anthropic activities. Results revealed that metals such as Pb, Cr, and Cd were deposited in the feathers originating from air and soil (exogenous process). Other metals such as Cu, Fe, Mn, and Zn, which are part of the tissue constitution of a living being, were absorbed through the pigeons' diet (endogenous process). There was a statistically significant difference between mean values of Cd, Pb, and Cr in the three collection sites. The order of metal concentrations were Civic Square > Zoo > Jataí, which shows highest levels of metal contamination in anthropic environments. Significant differences between Cd, Pb, and Cr in washed and unwashed feathers suggest that metal concentrations are directly related to exposure time due to exogenous sources. We concluded that it is possible to quantify and monitor metal levels in the environment by analyzing the feathers of urban feral pigeons. Furthermore, unwashed feathers were especially efficient to investigate endogenous and exogenous absorption of the metals in our study.

INTRODUCCIÓNEl plomo (Pb) es el metal pesado que históricamente más problemas sanitarios y de contaminación ha causado en el mundo [1][2][3][4] . A pesar de las muchas medidas adoptadas en contra de su utilización en las últimas dos o tres décadas 1,2,[4][5][6] , su pertinaz presencia en el aire, suelo, agua y alimentos sigue considerándose todavía un factor de riesgo de primera magnitud, en especial para niños 1,3,5 y para algunos animales silvestres 4,6,7 . No en vano, hasta principios del siglo XX fue, tras el hierro, el segundo metal más empleado, y RESUMENLa munición y los pesos empleados en actividades recreativas como la caza, el tiro y la pesca deportiva han sido fabricados tradicionalmente con plomo. En España la caza y el tiro son responsables de la dispersión en la naturaleza de cerca de 6.000 toneladas anuales del metal pesado, mientras que podemos estimar en 100 las aportadas por pescadores deportivos a las zonas acuáticas. Las pocas medidas legales que varios países han adoptado en contra del uso del plomo en esos deportes se han basado en las pruebas irrefutables que indicaban que cada año fallecían intoxicadas millones de aves, que ingerían inadvertidamente esos pequeños objetos de plomo hallados abandonados en sus hábitats naturales. En este trabajo se discute si el enfoque conservacionista que se ha dado hasta ahora al problema resulta adecuado, y si las evidencias de los daños sobre los seres humanos son o no suficientes para extender todavía más esas medidas de prohibición, en especial teniendo en cuenta que en niños se considera que no hay dosis de exposición segura. Se concluye que en algunos aspectos los datos ya existen, aunque en otros los estudios tóxico-epidemiológicos son todavía escasos, sugiriendo que al tema se le ha prestado poca atención. En cualquier caso, resulta preocupante constatar que el principio de precaución no se ha aplicado para solucionar un problema cuyos efectos sanitarios serán más a largo plazo que inmediatos.Palabras clave: Perdigones de plomo.

ABSTRACT Is Lead Used in Sports (Hunting, Shooting and Angling) an Underestimated Public Health Problem?Ammunition and fishing weights used in recreational hunting, shooting and fishing sports have been made traditionally with lead. In Spain, for example, hunters and shooters are responsible for the dispersion of some 6.000 tonnes of the heavy metal yearly, into wetland and dryland areas, and an estimated 100 tonnes are contributed by anglers to the aquatic zones. The few legal measures that several countries have adopted banning the use of the lead in these sports are based on the irrefutable proof that every year millions of birds were poisoned lethally, due to the inadvertent ingestion of lead shot and sinkers found in their habitats. We analyzed whether the present conservationist approach to the problem is suitable, and if the evidence of damage to human beings is, or is not, sufficient to warrant even more prohibitive measures, especial...

This article discusses a framework and tools for evaluating ecological resources and the effects of cleanup on hazardous waste sites, particularly those with ecological buffer lands. Environmental professionals are faced with assessing the risks of contamination to humans and ecological receptors (organisms and ecosystems) at hazardous waste sites. While exposure assessment has focused largely on human receptors, environmental managers have recently taken a broader view, recognizing the intrinsic value and aesthetic importance of ecological resources and services, and of including a range of stakeholders in remediation decisions. The assessment process involves understanding exposure pathways from source to receptor, and determining how best to interdict these pathways. Environmental characterization and exposure assessment, indicator and biomarker identification, and biomonitoring and surveillance are the major components of ecological assessments. Using the Department of Energy as a case study, this article offers a framework for ecological exposure assessment, recognizing that humans are important components of ecosystems and, like other biota, are exposed to contaminants that move through environmental media. O c 2007 Wiley Periodicals, Inc. INTRODUCTIONIncreasingly, the public has become concerned about environmental contamination from industrial, utility, urban, and agricultural sources. Governmental agencies and private industries that own contaminated lands face the often costly burden of remediating these lands to reduce current or future risk and to render the land usable. The U.S. Department of Energy (DOE) is faced with the task of cleaning up contamination left from the Cold War and the production of nuclear weapons. This daunting task involves some 113 sites in 34 states that contain chemical and radiological wastes (Crowley & Ahearne, 2002; DOE, 2001). DOE and other federal agencies are relinquishing some land that is no longer required for the agency's mission to other uses, and protecting the ecological resources on others. Many hazardous waste facilities have extensive buffer lands that hold important ecological resources. For example, approximately 79 percent of DOE land has been undisturbed for over 50 years because it served to buffer the nuclear production facilities 71A Framework for Analysis of Contamination on Human and Ecological Receptors at DOE Hazardous Waste Site Buffer Lands (DOE, 2001). The approaches and tools needed to examine the human and ecological risks, particularly on buffer lands, are varied and range from qualitative assessments to sophisticated geographical information system (GIS) models with predictive value.The objectives of this article are (1) to present the context for incorporating ecosystem exposure and ecological risk into future land-use planning, (2) to review tools and approaches needed to select appropriate future land uses, and (3) to weigh options at DOE sites for important buffer lands. Although human health risk considerations (both public and occupati...
