“…Toledo é um município com intensa atividade agrícola e, embora as nascentes estudadas sejam urbanas, o município é cercado por áreas com uso estritamente agrícolas (Figura 3), podendo ocorrer, portanto, o carreamento de partículas, para os a uentes, contendo fertilizantes fosfatados contaminados com Pb ou outras fontes fertilizantes contaminadas (Freitas et al, 2009;Gonçalves Jr et al, 2014). Sendo essa uma das possíveis explicações para a elevação dos níveis deste metal nesses corpos hídricos, diversos autores, tais como Hat eld (1993), Hat eld et al (1995) e Sperling (1996, evidenciam que a poluição oriunda da atividade agrícola é considerada do tipo difusa, de difícil identi cação, monitoramento e, consequentemente, de difícil controle e remediação.…”

“…Desta forma, tem-se procurado integrar a administração da água com a de outros recursos naturais e as atividades antrópicas, procedendo-se o manejo integrado de bacias hidrográ cas, considerado como a integração de todos os fatores (biológicos, físicos, culturais e socioeconômicos) envolvidos na complexa relação entre os componentes naturais e antrópicos (Drew, 1986 (Gonçalves Jr. et al, 2014).…”

RESUMOOs recursos hídricos deterioram-se diariamente com a inserção de contaminantes, sejam orgânicos ou inorgânicos. Dentre a poluição de fontes inorgânicas, a contaminação por metais é preocupante, pois alguns apresentam-se tóxicos mesmo em pequenas quantidades, causando bioacumulação e biomagni cação na cadeia tró ca. A presente pesquisa objetivou avaliar os teores de metais e parâmetros físicos e químicos no Arroio Marreco e na Sanga Panambi, cujas nascentes são localizadas na área urbana de Toledo-PR, a m de avaliar os possíveis impactos causados a esses cursos hídricos. Para tal, foram realizadas determinações mensais quanto aos teores de metais (Cu, Zn, Fe, Mn, Cd, Pb e Cr), bem como determinações quanto aos parâmetros físicos e químicos (turbidez, o pH, e sólidos dissolvidos totais) em 5 pontos amostrais de dois a uentes com nascentes urbanas de Toledo, PR. Os resultados foram submetidos a comparação com os limites máximos estabelecidos pela CONAMA 357/05, para águas doces de classe 2. Os elementos Cd e Pb atingiram, respectivamente, concentrações de 6,0 e 2,2 vezes superior ao permitido, indicando inserção e contaminação ambiental, possivelmente por atividades agrícolas e urbanas próximas. Além disso, valores obtidos para a turbidez também estão em desacordo com a legislação, se apresentando 1,5 vezes maior aos 100 UNT permitidos. Conclui-se que as más condições dos trechos em estudo são devidas a exposição de ambos corpos hídricos a impactos ambientais negativos causados por atividades antrópicas.

Among the inorganic sources of pollution, contamination with metals are worrying because some metals are presented toxic even in small amounts, causing bioaccumulation and biomagnication in the food chain. e present research aimed to evaluate the levels of metals and physical-chemical parameters in the Marreco and Panambi rivers, whose fountains are located in the urban area of Toledo -PR, in order to evaluate the possible impacts caused to these water sources. In order to do this, monthly determinations were performed on the metal content (Cu, Zn, Fe, Mn, Cd, Pb and Cr), as well as determinations on the physico-chemical parameters (turbidity, pH and total dissolved solids) in 5 points sample 1 Curso de Engenharia Ambiental, Pontifícia Universidade Católica do Paraná -PUCPR, Campus Toledo, PR, Brasil.

“…The metals occur naturally in the soil, however, elements such as Cadmium (Cd), Lead (Pb), Arsenic (As) and Selenium (Se) have unhealthy effects on various components of the biosphere (KabataPendias and Pendias, 2001); among these effects, the bioaccumulation and biomagnification is worth mentioning due to the risks they present to living organisms, being ways to concentrate the contaminants over time and even the food chain. For example, organisms presented in a contaminated soil can be exposed to various contaminants absorbing them slowly, reaching levels up to 100,000 higher in their tissues, as in aquatic organisms, leading these levels along the food chain (Souza et al, 2014;Gonçalves Jr. et al, 2014).…”

“…In this scenario, Gonçalves Jr et al (2014) presented several papers and case studies demonstrating the increasing number of cases of contamination in Brazilian soils. Also, one must take into account the toxic effects of these metals representing risks to living organisms, reducing plant growth, causing disturbing various metabolic processes that leads to yield losses, absorption and loss of commercial products quality Gonçalves Jr. et al, 2014).…”

The aim of this work is to identify the main sources of contamination of soils, their effects on organisms also presenting alternatives for remediation and decontamination of these contaminated environments. The soils have in their composition organisms that are naturally present, as well as the presence of contaminants in increasing proportion when compared to the world industrialization and modernization of agriculture; therefore, increase in evolution brings with it a bigger totality of compounds, resulting in worrying rates in the soils of Brazil, such as trace elements (Cadmium, Lead, Arsenic, Mercury, Copper) and compounds organic (pesticides) and inorganic (waste fossil fuels). In many instances, this contamination can decimate forms of life in the soil. With that, remediation and decontamination of these soils becomes a fundamental need for the current economic models, making bioremediation and phytoremediation techniques consist in a feasible alternative for remediation and decontamination of soil, presenting performances satisfactory in removal and stabilization of contaminants.

The exposome depicts the total exposures in the lifetime of an organism. Human exposome comprises exposures from environmental and humanistic sources. Biological, chemical, and physical environmental exposures pose potential health threats, especially to susceptible populations. Although still in its nascent stage, we are beginning to recognize the vast and dynamic nature of the exposome. In this review, we systematically summarize the biological and chemical environmental exposomes in three broad environmental matrices—air, soil, and water; each contains several distinct subcategories, along with a brief introduction to the physical exposome. Disease‐related environmental exposures are highlighted, and humans are also a major source of disease‐related biological exposures. We further discuss the interactions between biological, chemical, and physical exposomes. Finally, we propose a list of outstanding challenges under the exposome research framework that need to be addressed to move the field forward. Taken together, we present a detailed landscape of environmental exposome to prime researchers to join this exciting new field.
