A mathematical model to estimate the volume of grey water of pesticide mixtures. Repositório Alice
PARAIBA, L. C.; PAZIANOTTO, R. A. A.; LUIZ, A. J. B.; MAIA, A. de H. N.; JONSSON, C. M..
Abstract: We propose a model to estimate the grey water footprint of crops by calculating the volume of water necessary to dilute pesticide mixtures reaching freshwaters. The model requires short-term toxicity data from aquatic organisms based on EC50 values, soil pesticide half-life and soil sorption coefficient values, and does not require maximum concentration limit acceptable in water. The lixiviation rate and runoff rate of each pesticide was estimated by attenuation factor and by Soilfug model, respectively. The usefulness of the proposed model was illustrated by estimating the volume of grey water required to dilute the 17 most widely used herbicides in sugarcane crops of Brazil. The grey water footprint corresponding to the recommended agronomic...

A simple approach to integrate the ecotoxicological and chemical data for the establishment of environmental risk levels BABT
Cesar,Augusto; Abessa,Denis Moledo de Souza; Pereira,Camilo Dias Seabra; Santos,Aldo Ramos; Fernández,Nuria; Choueri,Rodrigo Brasil; DelValls,Tomas Angel.
In this work, multivariate and numeric methods were used to integrate the chemical and ecotoxicological data obtained for the sediments from the Santos Estuarine System, and for the vicinity of the discharges of the Submarine Sewage Outfall of Santos, in order to establish more accurately the environmental risks, identify the priority areas and thus provide guidance to control the programs and public policies. For both the datasets, the concentrations which exceeded numeric sediment guidelines tended to be associated to toxicity. For the estuary, this trend was corroborated by the correlations between the toxicity and Cu and PAHs levels, whereas for the sewage outfall region, this was observed through the correlation between the toxicity and Hg contents....

A simple HPLC method for the determination of halcinonide in lipid nanoparticles: development, validation, encapsulation efficiency, and in vitro drug permeation BJPS
Lopes,Clarissa Elize; Langoski,Gisele; Klein,Traudi; Ferrari,Priscileila Colerato; Farago,Paulo Vitor.
ABSTRACT Halcinonide is a high-potency topical glucocorticoid used for skin inflammation treatments that presents toxic systemic effects. A simple and quick analytical method to quantify the amount of halcinonide encapsulated into lipid nanoparticles, such as polymeric lipid-core nanoparticles and solid lipid nanoparticles, was developed and validated regarding the drug's encapsulation efficiency and in vitro permeation. The development and validation of the analytical method were carried out using the high performance liquid chromatography with the UV detection at 239 nm. The validation parameters were specificity, linearity, precision and accuracy, limits of detection and quantitation, and robustness. The method presented an isocratic flow rate of 1.0...

Action de l'acétate de tributyle-étain sur les oeufs et les larves D de deux mollusques d'intérêt commercial : Crassostrea gigas (Thunberg) et Mytilus galloprovincialis (Lmk) ArchiMer
Robert, Rene; His, Edouard.
The Tributyl tin acetate, a component of certain antifouling paints, has deleterious effects on eggs and D shaped larvae from Crassostrea gigas at 5 p.p.b. (HIS & ROBERT, 1980). Here we have tested concentrations as low as 1 p.p.b. on eggs and on 24 hours old larvae both from Crassostrea gigas and Mytilus galloprovincialis. The same results are got ; this product kills embryos and larvae in a few days ; it prevents growth of 24 hours old larvae exposed to this toxic. Mussels larvae seem to be less sensitive.

Acute intoxication by deltamethrin in jundia: emphasis on clinical, biochemical and haematological effects. Repositório Alice
GALEB, L. do A. G.; GANECO, L. N.; FREDIANELLI, A. C.; WAGNER, R.; FAM, A. L. P. D'A; ROCHA, D. C. C.; KIRSCHNIK, P. G.; PIMPÃO, C. T..
Deltamethrin (DM) is a synthetic pyrethroid pesticide highly toxic to aquatic organisms. Because of its lipophilic feature it can be highly absorbed by the fish gills, which partially explains the high sensitivity of these animals to DM exposure in concentrations up to a thousand times lower than in mammals. This study compared clinical, biochemical and haematological observations between DM intoxicated and nonintoxicated fish. The experiment involved five exposure conditions (control and four concentrations of DM) and was executed in triplicates with 4 animals per set (n=60). The first behavior changes represented by rapid operculum movement and irregular or on the surface swimming were observed shortly after exposure to the concentrations of 0.5, 1.0 and...

Acute Toxicity by Water Containing Hexavalent or Trivalent Chromium in Native Brazilian Fish, Piaractus mesopotamicus: Anatomopathological Alterations and Mortality. Repositório Alice
CASTRO, M. P.; MORAES, F. R. de; FUJIMOTO, R. Y.; CRUZ, C. da; BELO, M. A. de A.; MORAES, J. R. E. de..
This study evaluated the toxicity of hexavalent and trivalent compounds of chromium to the pacu, Piaractus mesopotamicus, in acute exposures of 96 h through mortality and histopathological responses. Hexavalent otassium dichromate was more toxic than trivalent compounds of chromium chloride, chromium oxide and chromium carbochelate. Sufficient mortalities occurred only with potassium dichromate to yield an LC50 value at 124.2 mg L-1. Hexavalent chromium caused reversible and irreversible lesions, which may affect organ functionality. Histopathological evaluation showed that trivalent chromium caused lesions of lower severity. Pacu subjected to different concentrations of chromium carbochelate showed no histopathological changes in the kidneys, liver, skin...

Acute toxicity of nitrite to matrinxã, Brycon cephalus (Günther, 1869), (Teleostei-Characidae) Ciência Rural
Avilez,Ive Marchioni; Aguiar,Lucia Helena de; Altran,Alexandre Eneas; Moraes,Gilberto.
Nitrite leads to many physiological and hematological disturbances followed by lethality. This work reports the lethal concentration of nitrite to juvenile matrinxã. Experiments were done at 24ºC, pH 6.7-7.0 under natural photoperiod. Fish were exposed to 0.2- 0.5- 1.0 and 2.0mg L-1 of nitrite N-NO2 for 96h. The 96-h LC50 of nitrite-N was calculated by the trimmed Spearman-Karber method (0.86±0.05mg L-1; 0.57-1.30 to 95%CI) and it was concluded that matrinxã is very sensitive to environmental nitrite. Therefore, care must be taken to prevent accumulation of nitrite in intensive culture systems of matrinxã.

Age and time exposure-related toxicity of fenthion to male and female Anastrepha fraterculus (Wied.) (Diptera: Tephritidae) Anais da SEB
Humeres,Eduardo; Da Cruz,Ivana B.M.; Oliveira,Alice K. de.
Effect of age, sex and time exposure of Anastrepha fraterculus (Wied.) to toxicity of fenthion was evaluated. The age of the flies was important to the appearance of the first intoxication symptoms; males and females of reproductive ages (30 and 60 days-old, respectively) were less susceptible to insecticide than flies in the remainder ages (four and 120 days-old). The effect of body weight on insect intoxication was not detected. LT 50 biossay with fenthion (varying from 3-7 minutes) showed a lower susceptibility of males than females at all ages. Adults of both sexes and 30 days-old submitted to continuous and discontinuous exposure to fenthion did not show toxic cumulative effect of the insecticide. The statistical analysis suggests a possible general...

Batista,Michelli Fernandes; Moscheta,Ismar Sebastião; Bonato,Carlos Moacir; Batista,Marcelo Augusto; Almeida,Odair José Garcia de; Inoue,Tadeu Takeyoshi.
Aluminum (Al) toxicity is one of the most limiting factors for productivity. This research was carried out to assess the influence of Al nutrient solution on plant height, dry weight and morphoanatomical alterations in corn (Zea mays L.) roots and leaves. The experiment was conducted in a greenhouse with five treatments consisting of Al doses (0, 25, 75, 150, and 300 µmol L-1) and six replications. The solutions were constantly aerated, and the pH was initially adjusted to 4.3. The shoot dry matter, root dry matter and plant height decreased significantly with increasing Al concentrations. Compared to the control plants, it was observed that the root growth of corn plants in Al solutions was inhibited, there were fewer lateral roots and the development of...
