“…Segundo o Decreto nº 4.074 de 4 de janeiro de 2002 [40] , os três órgãos competentes para o registro de agrotóxicos são: Ministério da Saúde (MS), Ministério da Agricultura, Pecuária e Abastecimento (MAPA) e Ministério do Meio Ambiente, através do IBAMA. e no século XVII começaram a empregar o sulfato de nicotina que era extraído das folhas de tabaco [34] .…”

“…Tal crescimento leva à utilização de maiores quantidades de agrotóxicos, gerando preocupação com os alimentos consumidos em grande quantidade e in natura [34] . É importante destacar que menos de 0,1% dos agrotóxicos que são aplicados atingem o alvo, enquanto o restante pode alcançar outros ambientes, como as águas subterrâneas e superficiais, solo e ar [50] .…”

“…Outro fator preocupante é a contaminação ocupacional que pode ser imediata [34] e pode trazer comprometimentos à saúde que variam em função do estado nutricional, idade e sexo do indivíduo. Existem dois tipos principais de intoxicações por agrotóxicos: a Intoxicação Aguda, na qual os sintomas surgem rapidamente, de forma leve, moderada ou grave, dependendo do tempo de exposição e da toxicidade dos agrotóxi-cos, e é caracterizada por fraqueza, vômitos, convulsões, contrações musculares, dores de cabeça, dificuldade respiratória, sangramento nasal; e a Intoxicação Crônica, que surge tardiamente, em função de exposições repetidas e gera danos, na maioria das vezes, irreversíveis [38,72] .…”

ResumoA presente revisão tem como objetivo reunir em um único manuscrito informações desde a produção agrícola do morango até os aspectos negativos que podem influenciar e atingir o meio ambiente ou gerarem preocupações com a saúde dos trabalhadores rurais e consumidores que tenham contato direto com o meio ambiente ou que consomem o morango in natura. O morango é uma das culturas que lideram, desde o ano de 2002, o ranking dos alimentos mais contaminados por resíduos de agrotóxicos no Brasil. A cromatografia líquida moderna é uma das técnicas analíticas mais desenvolvidas e empregadas para determinação de resíduos de agrotóxicos em alimentos. Palavras-chaveCLAE; agrotóxicos; morango. Strawberry: food, environmental and sanitary concerns, monitored by modern liquid chromatography AbstractThis review aims to present information in a single manuscript initiating with the agricultural production of strawberries and concluding with the negative aspects that influence environment or generate concerns about the health of farm workers and consumers who have direct contact with the environment or, even the consumers of fresh strawberries. Strawberry crops are those that leads, since the year 2002, the ranking of the foods most contaminated with pesticide residues in Brazil. Modern liquid chromatography is one of the most developed analytical techniques and is thus often employed for the determination of pesticide residues in foods.

Discrimination of soils managed with different sources of fertilization and plant species in organic and conventional farming through near‐infrared spectroscopy and chemometrics

BACKGROUND: The combination of near-infrared (NIR) spectroscopy and chemometrics can be used to group or discriminate soils based on spectral response. In this study, we conducted discrimination and classification analyses on soils managed with different sources of fertilization and plant species grown in organic and conventional farming systems. RESULTS: Principal component analysis explained 96% (PC1) and 3% (PC2) of the data variability and separated the soil samples of organic and conventional management systems. The wavenumbers that contributed most to the separation of the management systems were in the range of 3600 and 7300 cm −1 , especially the absorption peaks of 3700 and 4600 cm −1 (characteristic of C H and N H combinations), and 5200 and 7000 cm −1 (typical of O H combinations). Machine learning analysis using k-nearest neighbor and random forest algorithms was efficient in classifying soil samples according to management system with an accuracy of 97.8% and can therefore be used for future classification studies.CONCLUSION: Based on the results, we strongly recommend the use of NIR spectroscopy associated with chemometrics for discriminating soils grown with Malus domestica, Musa spp., Oryza sativa and Solanum tuberosum L. under organic and conventional management systems through spectral response.

Aquatic environmental pollution may cause biodiversity loss. Thus, monitoring studies are very important because fish health reflects both quality and sustainability of the environment, as well as of the individuals that live there. In the present report, genetic biomarkers (piscine micronucleus test; comet assay with blood, liver, and kidney cells) were used in specimens of Astyanax sp. to analyze the contamination level of the Cangüiri Farm through biomonitoring. The Cangüiri Farm, the old school farm of the Federal University of Paraná, is inside the Iraí River Environment Preservation Area, created in 1996 to preserve the sources of public water supply in Curitiba and metropolitan area. We verified that the fishes collected within the Cangüiri Farm area presented high damage levels, showing more environment contamination when compared to the specimens collected in the Costa Ecologic Park, used as reference in the present report. The results indicate that the Cangüiri Farm, which is inside an environment protection area, created especially for the protection of the fountainhead for water supply, may be contaminated. These toxic residues, which were remarkably persistent in the environment, are possibly derived from agricultural activities in the wider area. Thus, we suggest the analysis of the area with other biomarkers and for a longer time period.
