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 ...
Joint toxicity of copper and diazinon during embryonic and larval development of the common South American toad, Rhinella arenarum
(Taylor & Francis Ltd, 2016-06)
Copper (Cu) and diazinon are two widely distributed pollutants; they coexist in agro-ecosystems and cause toxicity to wild biota. This study proposes to analyse the joint toxicity of binary mixtures of Cu and diazinon on ...
Mixture toxicity of copper and nonylphenol on the embryo-larval development of Rhinella arenarum
(Springer Heidelberg, 2020-02)
Copper and nonylphenol are two commonly found chemicals in the aquatic environment, particularly in the distribution area of the amphibian Rhinella arenarum. The current work evaluated the lethal toxicity of equitoxic and ...
Joint Probabilistic Analysis of Risk for Aquatic Species and Exceedence Frequency for the Agricultural Use of Chlorpyrifos in the Pampean Region, Argentina
(Society of Environmental Toxicology and Chemistry, 2019-04-15)
The Pampa Húmeda region in Argentina is characterized by soybean, wheat, andmaize production, with intensive application of agrochemicals such as herbicides and insecticides. We used a joint probabilistic approach to analyze ...
In vitro effect of agriculture pollutants and their joint action on Pseudokirchneriella subcapitata acid phosphatase
(Pergamon-elsevier Science LtdOxfordInglaterra, 2007)
Accelerated eutrophication and toxicity in tropical reservoir water and sediments: an ecotoxicological approach
(Springer, 2018-05-01)
The aim of this study was to jointly show the results of three independent ecotoxicological studies performed to investigate pollutants in three Brazilian tropical reservoirs undergoing accelerated eutrophication. In order ...
Análise da influência de elementos de vedação na rigidez de juntas parafusadas em tração utilizando o software Excel
(Universidade Estadual Paulista (Unesp), 2018-11-28)
Some applications of bolted joints require that there is no possibility of loosening and subsequent leakage, such as pressure vessels and pipes containing toxic or hazardous materials. For this type of application, gaskets ...
Do the joint effects of size, shape and ecocorona influence the attachment and physical eco(cyto)toxicity of nanoparticles to algae?
(2020-03-15)
We systematically investigated how the combinations of size, shape and the natural organic matter (NOM)-ecocorona of gold (Au) engineered nanoparticles (ENPs) influence the attachment of the particles to algae and physical ...
