Este estudo teve como objetivo verificar a relação entre diferentes níveis de plumbemia e o repertório de habilidades sociais, problemas de comportamento e competência acadêmica de crianças e adolescentes. Participaram 155 crianças e adolescentes, com idade média de 13,10 anos, pertencentes a três grupos: alta plumbemia (superior a 10μg/dl), baixa plumbemia (inferior a 5μg/dl) e que viviam em ambiente similar, mas livre da contaminação por chumbo (grupo de comparação). Foram utilizados os instrumentos SSRS-BR e o IHSA-Del-Prette, respondidos pelos participantes e seus professores. Identificou-se comprometimento no repertório comportamental, acadêmico e social, associado ao nível de plumbemia. Esses resultados evidenciam os riscos associados à exposição ao chumbo. São discutidas explicações para alguns resultados contraditórios, levantando-se hipóteses e questões para novos estudos.

This study investigated the children s intellectual development with high and low blood lead level with the parenting styles in the respective interactions with these children. The WISC-III and IEP (Parenting Styles Inventory) were used. Were studied 40 children, with ages among 7 to 13 years old, and 40 parents, who lived in a risk spot near the contamination area. The children were divided into two groups: G1 – 20 children with blood lead level above 10µg/dl; and G2 – 20 children with blood lead level lower than 10µg/dl. The results indicated damages on WISC-III for the children with Pb-S than10µg/dl and prevalence of practices educational negatives were found in both groups, with statistical difference (5%). The environmental stimulation can minimize the damages caused by the lead poisoning, and the parent s positive educative practice can contribute as modulator of the lead s effect.

To understand the implications of lead contamination contributes to more effective public politics to eliminate exposure to the metal and orientation of interventions that minimize their effects. In this paper we intended to evaluate the effects of lead contamination in children, with the Teste de Desempenho Escolar (TDE). In Study 1, transversal, aimed to evaluate the influence of blood lead levels in 28 participants of both sexes, of seven to fifteen years, divided into two groups according to the level of contamination. In Study 2, longitudinal study aimed to evaluate the effects of contamination on the school ,performance of 10 children at an interval of four years. Results showed significant underperformance for children with higher levels of contamination and that the level of academic performance remains significantly lower than expected for the series in which they find themselves. The data seem to indicate the deleterious effects of lead contamination in school performance.

The lead contamination in children has been the subject of research in the field of public health. This study evaluated the academic performance of 102 children from first to fourth grade. The subjects were divided into two groups. The first group was composed of 34 children without lead poisoning or with poison at levels lower than 5 µg/dl. The second group was composed of 68 children with blood lead levels between 10 and 40 µg/ dl. The instruments used to evaluate the academic performance were anamnesis and a scholarly performance test called Teste de Desempenho Escolar, TDE. The results indicated better academic performances from the second group with significant differences in arithmetic, reading and general scores. In a comparison between genders, the girls had better performances than the boys. These results were consistent with the parents’ perception in anamnesis. Although other variables were present, the data showed great academic damage for children with higher leadpoison. These outcomes require political policies to control contamination and intervention in this population.

Millions of houses and apartments built before 1978 have paint that contains lead. Chips, dust, and fumes from this paint can be very dangerous if they are not handled properly. Lead is particularly hazardous to unborn babies, infants, and young children. Volunteers in painting and housing-rehabilitation programs often work in homes that contain lead paint. The work they perform can create a lead hazard if they disturb this paint and produce paint chips or dust. Volunteers Opening Doors is a video program for these volunteers. It explains how volunteers can protect housing residents,themselves, and their families from lead poisoning by using the five keys to lead safety: 1. Protect residents and their belongings. 2. Prepare the work area. 3. Protect yourself from dust and debris. 4. Work wet. 5. Work clean.

In an age of medical advances and specialization, Jean-Martin Charcot (1825-1893) helped found the discipline of neurology and in 1882 was appointed the first professor of Diseases of the Nervous System in France. As an investigator with broad interests and vast knowledge Charcot contributed to several other disciplines. An early mentor and dominant figure in Charcot's formative years was Pierre Rayer (1793-1867), famous for his seminal contributions to the study of the kidney, who gifted Charcot with his passion for clinical pathological correlations and likely a yearning for the study of kidney diseases. Famous for the clarity and incisiveness of his formal teaching presentations, Charcot lectured on the kidney at the Faculty of Medicine in Paris in 1877. Translated into English and published as a book titled Lectures on Bright's Disease, they became widely accessible and quoted in the literature through the present. In addition, at a time that he was already concentrating on the study of neurological disorders, Charcot maintained his life-long interest in the kidney and published original studies on the pathological changes of the kidney in gout and experimental lead poisoning, as well as supporting a study of hysterical ischuria by his students.

La intoxicación por ingestión de munición de plomo en aves silvestres es conocida en España desde finales del siglo pasado. Elevadas densidades de perdigones de plomo en diversos humedales de importancia internacional producen tasas de ingestión de perdigones cercanas al 70% en especies como el ánade rabudo (Anas acuta) y el plumbismo llega a ser una de las principales causas de mortalidad de la amenazada malvasía cabeciblanca (Oxyura leucocephala). El plumbismo también ha sido descrito en diversas especies de aves rapaces y se ha comprobado que la exposición al plomo es elevada en las especies más carroñeras y oportunistas. La contaminación de la carne de caza también ha sido objeto de estudio, debido a que en España se da la particularidad de cocinarla en escabeche, lo que incrementa la transferencia de plomo de la munición a la carne. Por el momento, la única acción llevada a cabo para reducir el riesgo de exposición al plomo de la munición en aves y humanos ha sido la prohibición desde 2001 del uso de perdigones de plomo en humedales protegidos. En esta revisión se hace un repaso a los estudios llevados a cabo en España sobre la contaminación por el plomo de la munición y el efecto que están teniendo las medidas hasta el momento adoptadas para reducir este riesgo.

Environmental indicators have been proposed as a means to assess ecological integrity, monitoring both chemical and biological stressors. In this study, we used nestling bald eagles as indicators to quantify direct or indirect tertiary-level contaminant exposure. The spatial and temporal trends of polychlorinated biphenyl (PCB) congeners were evaluated in nestling plasma from 1999–2014. Two hexa-chlorinated congeners, PCB-138 and 153, were detected with the highest frequency and greatest concentrations throughout Michigan. Less-chlorinated congeners such as PCB-52 and 66 however, comprised a greater percentage of total PCB concentrations in nestlings proximate to urbanized areas, such as along the shorelines of Lake Erie. Toxic equivalents were greatest in the samples collected from nestlings located on Lake Erie, followed by the other Great Lakes spatial regions. Nestling plasma samples were also used to measure concentrations of the most heavily-used group of flame retardants, brominated diphenyl ethers (BDEs), and three groups of alternative flame retardants, non-BDE Brominated Flame Retardants (NBFRS), Dechloranes, and organophosphate esters (OPs). BDE-47, 99 and 100 contributed the greatest to total BDE concentrations. Concentrations of structurally similar NBFRs found in this study and recent atmospheric studies indicate that they are largely used as replacements to previously used BDE mixtures. A variety of Dechloranes, or derivatives of Mirex and Dechlorane Plus, were measured. Although, measured at lesser concentrations, environmental behavior of these compounds may be similar to mirex and warrant future research in aquatic species. Concentrations of OPs in nestling plasma were two to three orders of magnitude greater than all other groups of flame retardants. In addition to chemical indicators, bald eagles have also been proposed as indicators to identify ecological stressors using population measures that are tied to the fitness of individuals and populations. Using mortality as a population vitality rate, vehicle collisions were found to be the main source of mortality with a greater incidence for females during white-tailed deer (Odocoileus virginianus) hunting months and spring snow-melt. Lead poisoning was the second greatest source of mortality, with sources likely due to unretrieved hunter-killed, white-tailed deer carcasses, and possibly exacerbated by density-dependent effects due to the growing population in Michigan.
