Summary There is concern about the health problems caused by pesticides in humans, which has led some grape producers to adopt organic procedures in their vineyards, and a certain amount of these grapes are directed to winemaking. Despite the approval awarded to this organic grape production by the certified organizations, there has been a demand to carry out a survey to determine the physicochemical composition of the wine derived from these products. Some of these wines were made from a single grape variety and others from more than one. For this survey, the samples consisted of five bottles of each type of wine, acquired from wineries and supermarkets in the Serra Gaúcha region, RS, Brazil. The analyses were carried out by physicochemical methods:...

Acephate and methamidophos residues in greenhouse and in field grown tomatoes

Horticultura Brasileira

Trevizan,Luiz Roberto P.; Baptista,Gilberto C. de; Papa,Geraldo.

Increasing horticultural production under protected cultivation requires more detailed studies about the occurence of pesticide residues, due to the special and peculiar environment under controlled conditions, in which some pests, that are of little concern in the field, become important. The insecticide acephate and its methamidophos metabolite residues were evaluated in greenhouse-grown tomatoes and compared to an open-field tomato crop. The treatments: (a) check; (b) one application of 75 g a.i. acephate.100 L-1 water; (c) one application of 150 g a.i.100 L-1 water; (d) four applications of 75 g a.i.100 L-1 water were evaluated. Fruit, leaf and soil samples were taken at (-1), zero, 1, 3, 7, 14, 21 days after the last or only application. The...

Nos últimos anos o Brasil atingiu um grande destaque no cenário agrícola internacional, consolidando-se como um dos maiores produtores de commodities agrícolas como soja, milho, café, açúcar, entre outras. Como efeito do modelo agrícola adotado pela maioria dos produtores, visando aumento da produtividade e aumento da área cultivada, o Brasil também tornou-se um dos maiores consumidores de agrotóxicos do mundo (KUGLER, 2012), uma vez que este insumo é imprescindível neste modelo de agricultura. Com o aumento no consumo de agrotóxicos as preocupações com os resíduos destas substâncias em alimentos ganham evidência e tornam- se cada vez mais frequentes. No Brasil várias iniciativas têm sido implementadas com o intuito de garantir níveis seguros de resíduos...

Abstract; Physicochemical and ecotoxicological measurements were employed to appraise the water quality of the Corumbataí River raw water (RW) intake, and that of its filtered (FW) and treated (TW) waters, processed by the Water Treatment Plant (WTP) of Piracicaba (SP, Brazil) during 2010. Some herbicides: ametrine, atrazine, simazine and tebuthiuron, were measured, with levels ranging from 0.01 to 10.3 microgram-g L-1. These were lower than those required to produce ecotoxicological effects to aquatic life based on published literature. Similarly, trihalomethanes, such as chloroform and bromodichloromethane produced as a result of the WTP process were also shown to be present in concentrations that would neither harm environmental nor human health....

The paper investigates the Turkish consumers' willingness to pay for a label that guarantees that pesticide residues in foods do not cause health problems. Contingent valuation survey was conducted to 1005 randomly selected households to elicit tomato purchasing behavior under alternative prices and residue scenarios. A tobit model was used to estimate a demand model. To determine the probability of purchase, a probit model was estimated.

Deltamethrin residues applied in different formulations in staked cucumber and the actions of insecticides on the pickleworm control

Horticultura Brasileira

Baptista,Gilberto C de; Trevizan,Luiz Roberto P; Franco,André A; Silva,Renato A da.

Pesticide residues, especially in vegetables and fruits, are a reason for concern with respect to the health of consumers and workers that need to return to areas that have been treated with these agrochemicals. The objectives of this experiment were to (a) study the behavior of deltamethrin residues from different formulations on cucumber fruits; and (b) correlate insecticide contents in the fruits with pickleworm control. Treatments were as follows: (a) control; (b) three 30 mL applications of deltamethrin 25 EC 100 L-1 water (emulsifiable concentrate formulation); (c) three 7.5 mL applications of deltamethrin 100 EC 100 L-1 water (emulsifiable concentrate); and (d) three 3.75 mL applications of deltamethrin 200 CS 100 L-1 water (concentrate suspension)....

Pesticides in “PERA” orange samples (N = 57) from São Paulo City, Brazil were assessed and the pesticide intake contribution was estimated for chronic risk assessment. Seventy-six pesticides were evaluated by the gas chromatography multi-residue method, including isomers and metabolites (4.332 determinations). The mean recoveries at the limit of quantification level were in the range of 72-115% and the relative standard deviation for five replicate samples was 1-11%. The limits of detection and quantification ranged from 0.005 to 0.4 mg.kg−1 and from 0.01 to 0.8 mg.kg−1, respectively. Pesticides were found in 42.1% of the samples at levels ranging from 0.06 to 2.9 mg.kg−1. Of the contaminated samples, 3.5% contained residues (bifenthrin and clofentezine)...

Influence of repeated applications of glyphosate on its persistence and soil bioactivity

PAB

Andréa,Mara Mercedes de; Peres,Terezinha Bonanho; Luchini,Luiz Carlos; Bazarin,Sheila; Papini,Solange; Matallo,Marcus Barifouse; Savoy,Vera Lucia Tedeschi.

Pesticide degradation studies are essential to evaluate its impact in the environment and on non-target organisms. The effect of repeated soil applications of the herbicide glyphosate on its dissipation and on soil microorganisms was studied by radiometric and microbial techniques. Results indicated fast dissipation of the [14C]-glyphosate or [14C]metabolites extractable residues (half-life of 0.92±0.29 month), but increasing half-lives of total mineralization ranging from 2.2 to 3.4 months as the number of applications increased from 1 to 4. No significant correlation was found between 14CO2 production and dehydrogenase activity.

ABSTRACT Neonicotinoids are a relatively new generation of insecticides that have been used for control of pests such as aphids, leafhoppers and whiteflies. This paper presents for the first time a determination of residues of four neonicotinoid insecticides (acetamiprid, thiamethoxam, thiacloprid and imidacloprid) in Chilean honey using QuEChERS extraction and UHPLC-MS/MS analysis. The limits of detection and quantification found for all analytes ranging from 0.34 to 1.43 μg kg-1 and from 0.30 to 4.76 μg kg-1, respectively. The extraction using QuEChERS method provided recoveries over 79% and the precision showed coefficient of variation lower than 20%. These data are in agreement with the international criteria that recommend general recovery limits of...

Organochlorine pesticides in residues in waters from the coastal area of Dar es Salaam and their effect on aquatic biota

OceanDocs

Mwevura, H.; Othman, O.C.; Mhehe, G.L..

Water samples were collected from Msimbazi and Kizinga rivers in Dar es Salaam and from the coastal marine environment receiving waters from these rivers during both the wet season and the dry season and analysed for various organochlorine pesticide residues using GC-ECD. The pesticides p,p’-DDE, p,p’-DDT, dieldrin and g-HCH were the only organochlorines detected at significantly greater concentrations above detection limits. There was a marked difference on the frequency of pesticide residue detection during the two seasons. All the wet season samples and 37.5% of the dry season samples contained p,p’-DDE at concentrations ranging from 0.05 to 0.45mg/l and 0.08 to 0.20mg/l respectively. p,p’-DDT was detected in 25% of the dry season samples at a...
