Effects of the herbicide glyphosate on biological attributes of Alpaida veniliae (Araneae, Araneidae), in laboratory
(Pergamon-Elsevier Science Ltd, 2010-02)
In the past decades there has been increasing interest in the study of arthropod predators as effective potential natural enemies to be used in the biological control of agricultural pests. In Argentina, transgenic soybean ...
Single and Combined Effects of Cypermethrin and UVR Pre-Exposure in the Microalgae Phaeodactylum Tricornutum
(Springer, 2021-09)
Coastal marine microalgae are exposed to anthropogenic pollutants, including pesticides from aquaculture/agriculture/household uses. Some microalgae species, such as Phaeodactylum tricornutum, can induce and accumulate ...
Genotoxic effect of a binary mixture of dicamba and glyphosate-based commercial herbicide formulations on Rhinella arenarum (Hensel, 1867) (Anura, Bufonidae) late-stage larvae
(Springer Heidelberg, 2016-06)
The acute toxicity of two herbicide formulations, namely, the 57.71 % dicamba (DIC)-based Banvel® and the 48 % glyphosate (GLY)-based Credit®, alone as well as the binary mixture of these herbicides was evaluated on ...
Are the damaging effects induced by the imazethapyr formulation Pivot® H in Boana pulchella (Anura) reversible upon ceasing exposure?
(Academic Press Inc Elsevier Science, 2018-02)
In the present study, the damage recovery capabilities of Boana pulchella tadpoles after acute exposure (96 h) to 0.39 mg/L concentration of the imazethapyr (IMZT)-based herbicide formulation Pivot H (25% IMZT LC50 value) ...
Effect on the growth and development and induction of abnormalities by a glyphosate commercial formulation and its active ingredient during two developmental stages of the South-American Creole frog, Leptodactylus latrans
(Springer Heidelberg, 2016-12)
We evaluated the acute lethal and sublethal effects of technical-grade glyphosate (GLY) and the GLY-based commercial formulation Roundup ULTRA MAX® (RU) on two Gosner stages (Gss) 25 and 36 of the South-American Creole ...
Do Larvae and Ovipositing Chironomus riparius (Diptera: Chironomidae) Females Avoid Copper-Contaminated Environments?
(TAYLOR & FRANCIS INC, 2009)
Studies on the avoidance behavior of aquatic organisms to contaminants have confirmed that such behavior can be relevant in field situations. However, almost all toxicity tests involve the forced exposure of organisms to ...

This study proposes short-term sublethal assays for the tropics using the fish Poecilia reticulata. Assays were evaluated under realistic exposure scenarios by simulating a runoff over an agricultural area sprayed with ...
Ecotoxicological assessment of the anticancer drug cisplatin in the polychaete Nereis diversicolor
(2017-01-01)
Anticancer drugs are designed to inhibit tumor cell proliferation by interacting with DNA and altering cellular growth factors. When released into the waterbodies of municipal and hospital effluents these pharmaceutical ...
Toxicity of the insecticide chlorpyrifos to the South American toad Rhinella arenarum at larval developmental stage
Chlorpyrifos (CPF) is an insecticide widely used for pest control in the fruit-productive region of North Patagonia, Argentina, where it is found in superficial waters. The aim of this study was to establish the toxic ...
