“…Tanabe and Kawata (2004) used LC-MS/MS for analyzing atrazine in water using two types of solid-phase extraction and determined the LoD as 1.6 lg L -1 ; in other words, this value is almost 23 times greater than that obtained in the present study, which used DAI. In the same study, Tanabe and Kawata (2004) obtained a retention time of 13.3 min, whereas in the present study, the retention Jacomini et al (2009) analyzed residues of ametrine in surface water through LC/MS-MS and found 0.02 lg L -1 as the LoQ, which is also lower than that found in the present study. However, the recovery obtained was 51.2 % with a CV of 6.9 %.…”

A rapid and sensitive method using liquid chromatography coupled with mass spectrometry triple quadrupole direct aqueous injection for analysis of atrazine and ametrine herbicides in surface waters was developed. According to the validation method, water samples from six different locations in the Piracicaba River were collected monthly from February 2011 to January 2012 and injected into a liquid chromatographer/dual mass spectrometer without the need for sample extraction. The method was validated and shown to be precise and accurate; limits of detection and quantification were 0.07 and 0.10 µg L(-1) for atrazine and 0.09 and 0.14 µg L(-1) for ametrine. During the sampling period, concentrations of atrazine ranged from 0.11 to 1.92 µg L(-1) and ametrine from 0.25 to 1.44 µg L(-1). After analysis of the herbicides, Danio rerio were exposed a range of concentrations found in the river water to check the induction of micronuclei and nuclear abnormalities (NAs) in erythrocytes. Concentrations of atrazine and ametrine >1.0 and 1.5 µg L(-1), respectively, induced MN formation in D. rerio. Ametrine was shown to be more genotoxic to D. rerio because a greater incidence of NAs was observed compared with atrazine. Therefore, environmentally relevant concentrations of atrazine and ametrine found in the Piracicaba River are dangerous to the aquatic biota.

“…Entre os herbicidas utilizados no Brasil, destaca-se o ametryn, que pertence à classe das triazinas e é utilizado em pré e pós-emergência no controle de mono e dicotiledôneas de plantas daninhas em diversas culturas (Jacomini et al, 2009). Devido ao grande uso do ametryn na cultura da cana-de-açúcar, esse herbicida tem sido aplicado, repetidas vezes, em diferentes solos sem o conhecimento básico de suas interações com estes.…”

“…Devido ao grande uso do ametryn na cultura da cana-de-açúcar, esse herbicida tem sido aplicado, repetidas vezes, em diferentes solos sem o conhecimento básico de suas interações com estes. Isso tem levado ao uso incorreto do herbicida quanto às doses aplicadas, tendo como consequência a contaminação do solo e das águas superficiais em regiões canavieiras (Queiroz & Lanças, 1997;Monquero et al, 2008;Jacomini et al, 2009). …”

RESUMO -O conhecimento dos fatores que influenciam a lixiviação dos herbicidas no solo possibilita o uso seguro do produto do ponto de vista ambiental, além de ser fundamental para que se façam recomendações tecnicamente corretas. Objetivou-se com este trabalho avaliar a lixiviação do ametryn em quatro solos brasileiros, com diferentes características físico-químicas, e comparar o método cromatográfico com o biológico em estudos de mobilidade desse herbicida. Os substratos avaliados foram: Latossolo Vermelho-Amarelo (LVA) pH 5,40 e pH 6,11, Latossolo Vermelho-Amarelo húmico (LVAh) pH 4,8 e pH 6,24, Latossolo Vermelho (LV) pH 5,00 e pH 6,06 e Latossolo Amarelo (LA) pH 6,30 e 10 profundidades na coluna (0-5, 5-10, 10-15, 15-20, 20-25, 25-30, 30-35, 35-40, 40-45 e 45-50 cm), mais uma testemunha de cada substrato sem aplicação do herbicida, com quatro repetições. Os substratos foram colocados em colunas devidamente preparadas para estudos de mobilidade. A espécie Cucumis sativus foi utilizada como bioindicadora da presença do ametryn. Concluiu-se que os teores de matéria orgânica e pH dos solos avaliados foram as características que mais interferiram na mobilidade do ametryn e que o ensaio biológico se mostrou eficiente como indicador da lixiviação desse herbicida nas colunas. Comprovou-se que o método biológico por bioensaios pode ser utilizado como método preliminar ou complementar ao método instrumental, visando à confirmação de resultados e, ou, redução de custos e tempo das análises.Palavras-chave: herbicida, impacto ambiental, características do solo, bioensaio, cromatografia líquida.

“…It was observed that in the sugarcane region of northeastern Brazil, as well as in other regions of the country, this herbicide was applied on a large scale, on different soil types, without the basic knowledge of its interaction with them. The incorrect use of this tool, especially for what concerns the applied dose, leads to the contamination of soil and surface water in sugarcane cultivated regions (Queiroz and Lanças, 1997;Monquero et al, 2008;Jacomini et al, 2009). …”

Ametryn Leaching in Soils from the Sugarcane Region in Northeastern Brazilian

-Ametryn is one of the most widely used herbicides in the sugarcane culture. Little is known about the interactions between this herbicide and the attributes of soils in the sugarcane region of northeastern Brazil. This knowledge, before recommending herbicide, will minimize the negative effects on the environment, particularly on water resources, and will ensure weed control efficacy. In this work, ametryn leaching potential was estimated through bioassays and chromatography, in five soils from the sugarcane region in northeastern Brazil: Quartzarenic Neosol (Entisol); Red Argisol (Ultisol); Ferrihumiluvic Spodosol (Spodosols); Red-Yellow Acrisol (Oxisol) and Haplic Cambisol (Inceptisols). To achieve this, columns were prepared with samples of the respective soils. On top of these columns ametryn was applied and, 12 hours later, a 60 mm rainfall was simulated. After water draining (72 hours after herbicide application), the columns were longitudinally opened to withdraw samples of each soil, every 5 cm. On some of these samples, ametryn quantification was performed by high-performance liquid chromatography and, on the others, biological assays were performed to confirm the results. Ametryn mobility was influenced by the physical-chemical characteristics of soils, mainly by organic matter content, texture and cation exchange capacity (CEC). However, this cannot be considered for Ferrihumiluvic Spodosol, whose cementing characteristics restrict the infiltration of water and organic compounds. Increased leaching ametryn occurred in Quartzarenic Neosol (Entisol), with higher herbicide concentration in the 5 to 10 cm depth layer, in relation to the 0 to 5 cm surface layer, indicating possible agronomic efficiency loss and higher risk of groundwater contamination.Keywords: herbicide, liquid chromatography, bioassay, mobility. RESUMO -O ametryn é um dos herbicidas mais utilizados na cultura da cana-de-açúcar, e pouco se conhece sobre as interações desse herbicida com os atributos dos solos da região canavieira do Nordeste brasileiro. Esse conhecimento antes da recomendação do herbicida permite minimizar os efeitos negativos ao ambiente -em especial, aos recursos hídricos -e garantir a eficiência no
