Developmental Toxicity Assessment of a Chlorothalonil-Based Fungicide in a Native Amphibian Species
(Springer, 2020-04)
The toxicity of a commercial formulation of the fungicide chlorothalonil in sensitive stages of the native amphibian Rhinella arenarum (Ra) was assessed by means continuous treatments from embryo and larval development and ...
Determination of toxic and potentially toxic elements in rice and rice-based products by inductively coupled plasma-mass spectrometry
(Elsevier, 2019-06-30)
A study was undertaken to quantify the concentration of toxic and potentially toxic elements in samples of rice, rice crackers, rice noodles, infant cereals and rice vinegar available in the Argentine market. The determination ...
Synergy between Diazinon and Nonylphenol in toxicity during the early development of the Rhinella arenarum toad
(Springer, 2016-02)
Diazinon is an extensively applied organophosphate pesticide, and nonylphenol is one of the major degradation products of nonylphenol polyethoxylates which are commonly used as surfactant in pesticide formulations. Both ...
Not all toxic butterflies are toxic: high intra- and interspecific variation in sequestration in subtropical swallowtails
(2017-12)
Many herbivorous insects make use of plant secondary metabolites by consuming and storing
these toxic compounds in their body tissue or integument, thereby obtaining chemical defense against their
natural enemies. ...
Riparian strips as attenuation zones for the toxicity of pesticides in agricultural surface runoff: Relative influence of herbaceous vegetation and terrain slope on toxicity attenuation of 2,4-D
(Elsevier, 2021-09)
Pesticides reach aquatic ecosystems via surface runoff becoming one of the main contributors to their deterioration. Among the strategies to mitigate these impacts, the use of riparian strips is recommended, but the knowledge ...
Toxicity and genotoxicity assessment in sediments from the Matanza-Riachuelo river basin (Argentina) under the influence of heavy metals and organic contaminants
(Academic Press Inc Elsevier Science, 2017-01)
The aim of this study was to investigate the parameters of chemical extraction associated with the detection of toxicity and genotoxicity in sediment sample extracts. Quantitative analysis of metals and polycyclic aromatic ...
Comparative toxicity of endosulfan and diazinon on the embryo-larval development of the South American toad, Rhinella arenarum
(Inderscience, 2017-03)
The toxicity of endosulfan and diazinon were comparatively analyzed on the early development of the South American toad, Rhinella arenarum. Pesticides varied greatly in their effects on survival, with concentration-, time- ...
Fulminant streptococcal toxic shock syndrome
(Royal College of Physicians of Edinburgh, 2018)
We present a case of a previously healthy 37-year-old male who developed fever, nausea, vomiting, diarrhoea, and hypovolaemia. Within 5.5 h he presented with tachycardia, tachypnoea, became hypotensive and displayed a ...
Insecticidal and Insect-repellent Activities of Essential Oils from Verbenaceae and Anacardiaceae Against Rhizopertha dominica
(Natural Products Inc., 2009-09)
Essential oils extracted from leaves of Aloysia polystachya and A. citriodora (Verbenaceae) and from leaves and fruits of Schinus molle var. areira (Anacardiaceae) were tested for their repellent and toxic activities against ...
