“…Em 1984, a CETESB (Companhia de Tecnologia e Saneamento Ambiental), ligada à Secretaria do Meio Ambiente do governo do estado de São Paulo, deu início a um intensivo programa de controle da poluição na área desse pólo 6 . Desde então, alguns estudos foram realizados para identificar e determinar os níveis de contaminação no ar, na água, nos sedimentos e na biota 1,2,6,7 . O papel dos sedimentos em um cenário impactado tem sido reconhecido, particularmente devido à sua capacidade de concentrar os metais-traço presentes na água 8 .…”

Recebido em 22/3/05; aceito em 28/6/05; publicado na web em 20/1/06 SPATIAL AND SEASONAL VARIABILITY OF TRACE-ELEMENT CONCENTRATIONS IN SEDIMENTS FROM THE SANTOS-CUBATÃO ESTUARINE SYSTEM, SÃO PAULO, BRAZIL. Multi-element analyses of sediment samples from the Santos-Cubatão Estuarine System were carried out to investigate the spatial and seasonal variability of trace-element concentrations. The study area contains a rich mangrove ecosystem that is a habitat for tens of thousands of resident and migratory birds, some of them endangered globally. Enrichments of metals in fine-grained surface sediments are, in decreasing order, Hg, Mn, La, Ca, Sr, Cd, Zn, Pb, Ba, Cu, Cr, Fe, Nb, Y, Ni and Ga, relative to pre-industrial background levels. The maximum enrichment ranged from 49 (Hg) to 3.1 (Ga). Mercury concentrations were greater in the Cubatão river than in other sites, while the other elements showed greater concentrations in the Morrão river. Concentrations of Mn were significantly greater in winter and autumn than in summer and spring. However, other elements (e.g. Cd and Pb) showed the opposite, with greater concentrations in summer and spring. This study suggests that seasonal changes in physical and chemical conditions may affect the degree of sediment enrichment and therefore make the assessment of contamination difficult. Consequently, these processes need to be considered when assessing water quality and the potential contamination of biota.

“…Branco and Piaçabuçu rivers, and by the installation of shantytowns and inhabitations not attended, till the present, by a sewage collection system; also SVCE receives contributions from multiple contamination sources (LAMPARELLI et al, 2001;SANTOS-FILHO et al, 1993).…”

“…Investigations conducted in 1970's and 1980's indicated that the SVCE waters and sediments were not strongly polluted (CETESB, 1981), whereas recent studies detected moderated to high levels of contamination, especially in sediments and biota (AGUIAR et al, 2008;LAMPARELLI et al, 2001;HORTELLANI et al, 2005;SANTOS-FILHO et al, 1993). Sampaio et al (2008) Although pollution in SVCE and its contributors has increased along the recent decades, fishing and extraction of invertebrates are still made by the local population; for them, fishes and seafood constitutes the main source of proteins, and risks may occur due to consumption of contaminated food (PEREIRA et al, 2002).…”

“…The concentration of contaminants, including metals, in fish tissues is commonly reported as dependant of age, feeding habits and position in the food chain (TRUCCO et al, 1990). The contaminants accumulated in the biota may be further transferred to the man through the consumption of contaminated seafood (TAVARES and CARVALHO, 1992;SANTOS-FILHO et al, 1993;METIAN et al, 1998). Afterwards, short-and long-term effects may occur, and normally involve cellular, biochemical (enzymes regulation), physiological and behavioral disturbances, reproductive disorders, cognitive disturbances and even cancer (STORELLI, 2008;LIAO and PING, 2003;GOYER et al, 2004).…”

“…A study of the cities in the Serra Gaúcha region (20), as well as two studies (48,52) that did not specify the region, analyzed data from Brazil using information systems. The population studied comprised 9,971 individuals, with variation between groups: children (5, 108) (17,31,36,38), adolescents (25) (40), rural workers (1,590) (20,27,28), adults (2,740) (15,25,26,33,51), and search through reports of the rural population (475) (29). Regarding the population of the studies that report on notifications of intentional poisonings and suicides in adults, a total of 242,338 cases (30,34,48,49,59) is comprised.…”

Brazil is among the biggest pesticide consumers in the world, with its population severely exposed to tons of such substances, both because of environmental contamination and occupational use. The health consequences of pesticide exposure are well-documented, but still sparse regarding Brazilian population. This study systematically reviewed the Brazilian studies published that address the relationship between exposure to pesticides and health problems in the Brazilian population. Also, information about pesticide use in Brazil is provided. The included studies showed that exposure to pesticides has a relevant impact on the health of the Brazilian population, regardless of age and gender, and on workers in rural areas or not. Most poisoning events seem to result from the continuous use of pesticides, whether occupationally or environmentally, characterizing a public health problem. The major consequences reported in literature were damage to the central nervous system, cancer, deleterious effects on rural workers' health, intoxications, malformations, and endocrine changes. These findings point out the need to understand the impact of chronic exposure to pesticides on severely exposed people and highlight the importance of creating public policies to protect them and avoid disease occurrence.
