“…This is particularly important when assessing risk to the ecosystem characterized by frequent chemical inputs (as the case of the agroecosystems). For instance, exposures to PPPs are not dependent on constant but on pulsed concentrations, the peak and duration of which depend on the interactions between the PPPs and the soil [40, 41]. The current study removed the upper sward before collecting the soil to test, according to the proposed guidelines.…”

The Italian legislation on contaminated soils does not include the Ecological Risk Assessment (ERA) and this deficiency has important consequences for the sustainable management of agricultural soils. The present research compares the results of two ERA procedures applied to agriculture (i) one based on the “substance-based” approach and (ii) a second based on the “matrix-based” approach. In the former the soil screening values (SVs) for individual substances were derived according to institutional foreign guidelines. In the latter, the SVs characterizing the whole-matrix were derived originally by the authors by means of experimental activity.The results indicate that the “matrix-based” approach can be efficiently implemented in the Italian legislation for the ERA of agricultural soils. This method, if compared to the institutionalized “substance based” approach is (i) comparable in economic terms and in testing time, (ii) is site specific and assesses the real effect of the investigated soil on a battery of bioassays, (iii) accounts for phenomena that may radically modify the exposure of the organisms to the totality of contaminants and (iv) can be considered sufficiently conservative.

“…Alguns pesticidas podem estar presentes no ar, trazendo riscos a saúde humana. [10][11][12] A elevação da temperatura e a influência do pH nos princípios ativos podem afetar tanto a sua solubilidade quanto a volatilidade destes compostos. 13 De acordo com Utzig e Sottoriva, a mobilidade dos agrotóxicos depende das características pedológicas e do próprio composto, das condições climáticas e topográficas da região.…”

. In present times, the Brazil is in the middle of the largest pesticide consumers worldwide, which demands proper control of environmental contamination. This study evaluated herbicides, acaricide, insecticides and fungicides in water and sediment carried-out from Lageado Tacongava hydrographic basin, Rio Grande do Sul, Brazil. For analysis, a QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe), and/or SPE (Solid-Phase Extraction) using HPLC (High Performance Liquid Chromatography) with MS (Mass Detector) was optimized. As result, the Linearity R 2 > 0.99; Recuperation between 78 a 117%; and RSD < 20% for the 70 compounds simultaneously analyzed. The Acetamiprid, Azoxystrobin, Bendiocarb, Fenamidone, metribuzin, Pendimethalin, pyridaben, Thiophanate-methyl and Truflumizole found in water, and Acetamiprid, Azoxystrobin, Bendiocarb, boscalid and thiophanate-methyl in sediment, at concentrations from 0.1 µg kg -1 to 39.6 µg kg -1 . Standard of pesticide residues in water and sediment studies are needed to evaluate such contamination. Regional samplings standard, as was done here, will be useful in a future water resources contamination mapping.Keywords: pesticides; QuEChERS; HPLC-HRMS; sediment; water resources. INTRODUÇÃOA produção agrícola brasileira tem tido grande destaque em um contexto mundial. 1 O crescimento da produção é acompanhado pelo incremento da utilização de agrotóxicos, sem um controle mais efetivo do seu consumo. Isto pode implicar em um aumento dos impactos sobre os ecossistemas aquáticos e a biota do solo. 1 O Brasil é o quinto maior país em área territorial (equivalente a 47% do território sul-americano). A Organização das Nações Unidas para Agricultura e Alimentação (FAO) o considera essencialmente agrícola, apresentando área cultivada de aproximadamente 75 milhões de hectares. 2 Por sua grande extensão territorial, diferentes produtos são cultivados no país, de acordo com o clima. No Rio Grande do Sul, uma das culturas mais exploradas é a dos grãos. Estima-se que a área plantada prevista com grãos na safra de verão 2015/2016 no estado tenha ficado estável, podendo atingir 7,352 milhões de hectares, com avanço de apenas 0,74% ante 2014/15. 3 O país é um dos maiores consumidores de pesticidas, com uma forte expansão nos ultimos 40 anos, um aumento de 700%. Nos úl-timos 5 anos, uma média de 300 mil toneladas de agrotóxicos foram comercializadas. O estado do Rio Grande do Sul possui um destaque neste consumo estando na 4 o posição (12% do total) em 2015. 4 A aplicação incorreta e excessiva de pesticidas pode causar desequilíbrios ambientais com efeitos agudos e crônicos nos organismos vivos. 5 A magnitude dos efeitos depende da toxicidade da substância, da dose, do tipo de contato e do organismo. 6 Alguns destes compostos são reconhecidamente persistentes, permanecendo no ambiente por muito tempo sem sofrer alteração. 7 Assim, os dados referentes à qualidade da água nos rios brasileiros podem ser considerados críticos.O ministério da saúde definiu por meio do decreto 4.074 de 04 de janeiro...

“…The model allows users to define in a GIS environment thousands of gridded or scattered receptors located close to the ground, far from buildings, on horizontal or near-horizontal terrain, and thousands of complex sources with hundreds of vertices and holes. This scenario is common in agricultural processes [23,24,[29][30][31][32][33][34], in case of emissions from water bodies [35], from contaminated soils and during accidents [36,37], in mining and quarries [38,39]. This aspect makes CAREA potentially useful for many studies requiring the simulation of the concentrations and of the deposition of substances emitted by areal sources [26].…”

This work originates from an epidemiological study aimed to assess the correlation between population exposure to pesticides used in agriculture and adverse health effects. In support of the population exposure evaluation two models implemented by the authors were applied: a GIS-based proximity model and the CAREA atmospheric dispersion model. In this work, the results of the two models are presented and compared. Despite the proximity analysis is widely used for these kinds of studies, it was investigated how meteorology could affect the exposure assessment. Both models were applied to pesticides emitted by 1519 agricultural fields and considering 2584 receptors distributed over an area of 8430 km 2 . CAREA output shows a considerable enhancement in the percentage of exposed receptors, from the 4% of the proximity model to the 54% of the CAREA model. Moreover, the spatial analysis of the results on a specific test site showed that the effects of meteorology considered by CAREA led to an anisotropic exposure distribution that differs considerably from the symmetric distribution resulting by the proximity model. In addition, the results of a field campaign for the definition and planning of ground measurement of concentration for the validation of CAREA are presented. The preliminary results showed how, during treatments, pesticide concentrations distant from the fields are significantly higher than background values.
