Ecotoxicological effects of commercial herbicides on the reproductive system of aquatic arthropod Limnocoris submontandoni (Hemiptera: Naucoridae)

Braz. j. biol; 84 (), 2024
Abstract Worldwide, conventional agriculture makes extensive use of pesticides. Although the effects of herbicides are relatively well known in terms of environmental impacts on non-target organisms, there is very little scientific evidence regarding the impacts of herbicide residues on aquatic arthropod...

Exposure to the herbicide atrazine induces oxidative imbalance, morphological damage and decreased survival in juvenile fish

Biosci. j. (Online); 39 (), 2023
Synthetic herbicides have been intensively used in weed control, although often involved in environmental contamination, critically affecting non-target species. However, never was investigated the effect of commercial formulation using atrazine on developing juvenile fish exposed for 35 days. Juveniles ...

Exposure of Artemia salinato glyphosate and bioremediation by isotherapy

Artemia salina, an ecotoxicity bioindicator, isa microcrustacean belonging to the order Anostraca. Glyphosate is an herbicide widely used to control weeds. However, its intoxication can cause serious damage to human health and the balance of the environment, given its effects as an endocrine dis...

Environmental parameters modulate lead chloride toxicity on Artemia salina

Different environmental conditions can influence the effects of toxic agents on living beings. Recently, a series of experiments performed in Artemia salina submitted to different kinds of intoxication have shown that both, isotherapic and succussed watercan change Artemia salina ́s bio resilience at di...

Mercury chloride toxicity attenuation of the Brine Shrimp Artemia Salinaafter treatment with Mercurius corrosivusas isotherapic

Isotherapics preparedfromtoxic substances have been described as attenuation factors for heavy metal intoxicationin aquatic animals. Herein, Artemia salinaand mercury chloride were usedas a model to identify treatment-related bioresilience. The aim was to describe the effects of Mercurius cor...

Ecotoxicología ¿Cómo afecta a las comunidades faunísticas de las playas del Pacífico de Guatemala?

Cienc. tecnol. salud; 9 (1), 2022
La ecotoxicología estudia los efectos de los contaminantes químicos producidos por acción antropogénica en los diferentes ecosistemas. Las playas, son un ecosistema de interés, ya que en estas ocurre una gran cantidad de sedimentación y por lo tanto tienen la capacidad de acumular significativas co...

New Insights into the Gametogenesis of Biomphalaria glabrata (Mollusca, Gastropoda, Pulmonata): Implications for Histopathological Assessment

Abstract The reproductive system has a fundamental role in population dynamics and several reproduction strategies have been shaped by the environment over time. Many environmental pressures are generated by releasing pollutants, as endocrine disruptors, that can affect the reproductive system of individ...

Evidence of mutagenic and lethal effects of herbicides on Amazonian frogs

Acta amaz; 50 (4), 2020
Os anfíbios são ótimos bioindicadores porque são sensíveis à poluição química, indicando alterações ecossistêmicas pela presença de ou pela exposição a compostos químicos. Aqui nós relatamos evidências do impacto de herbicidas, incluindo glifosato, em anfíbios em uma localidade na Amaz...

Different diets with and without inclusion of antimicrobial additives alter the toxicity of swine manure to springtails and earthworms?

Biosci. j. (Online); 36 (3), 2020
The objective of this study was to measure the impact on part of soil fauna of application of non-stabilized (fresh) manure from post-weaning pigs fed diets, formulated with or without the use of dual-purpose wheat (15% inclusion), and with or without the use of antimicrobial growth-promot...

Efeitos das nanopartículas de Óxido de Zinco (NPs ZnO) em alguns aspectos da sobrevivência, reprodução e desenvolvimento de Biomphalaria glabrata (Say, 1818) (Gastropoda: Pulmonata)

A nanotecnologia representa uma tendência chave na ciência e tecnologia do século XXI. As nanopartículas de óxido de zinco (NPs de ZnO) estão entre as mais utilizadas devido a sua capacidade de refletir, absrover e dispersar a radiação ultravioleta. A partir da sua larga utilização em fotoprote...
