“…Results from this study showed a concentration and time-dependent increase in nuclear abnormalities in C. gariepinus exposed to atrazine, butachlor and glyphosate. It was similar to the findings of Nwani et al (2020) who reported an increase in micronucleus frequency in C. gariepinus exposed to three commercial herbicides. Cavas (2011) reported a significant increase in the frequencies of MN and DNA strand breaks in the erythrocytes of Carassius auratus exposed to sub-lethal concentrations of commercial atrazine formulation.…”

“…Atrazine is an endocrine disruptor that can cause hormone imbalance (EPA 2012); while glyphosate is a neurotoxin, which acts by inhibiting acetylcholinesterase (USEPA 2011). The observed LC50 values of the three pesticides varied with those from previous studies ofNwani et al (2020) who reported LC50 values of 4.84mg/l and 54.74mg/l for butachlor and atrazine pesticides exposed to C. gariepinus and Ayoola (2008a) who reported LC50 value of 1.50mg/l for glyphosate exposed to Nile tilapia.Plate 4.

Pesticides from agricultural run-off pose a severe threat to non-target organisms, such as fishes. This study was carried out to evaluate acute toxicity and histological and genotoxic effects (erythrocytic nuclear abnormalities) of lethal and sub-lethal concentrations of three commonly used pesticides: Atrazine, Butachlor and Glyphosate on the African mud catfish (Clarias gariepinus). Fishes were exposed to the pesticides for 96h periods to determine their LC50 and the sub-lethal effect at various concentrations (1/10th, 1/100th , 1/1000th 96h LC50) over 28 days. The 96h LC50 values were 7.63mg/l, 0.7mg/l and 15.97mg/l for atrazine, butachlor and glyphosate, respectively. Histological sections of the liver of C. gariepinus exposed to the three pesticides showed mild vascular congestion but no necrosis in the tissue. There was a significant (p<0.5) dose-dependent increase in micronuclei and nuclear abnormalities in the erythrocytes of exposed C. gariepinus compared to the control by 28 days. The study confirmed that C. gariepinus are at risk of adverse effects from exposure to pesticides. Discharge of agricultural run-off around water bodies should be prevented or prohibited to avoid adverse effects on aquatic life.

“…Ainda, conforme demonstrado por Shahjahan et al (2019), a velocidade, sensibilidade e confiabilidade do teste de MN, no sangue periférico de peixes, é usado intensivamente para a avaliação de contaminantes em ambiente aquático. Esses resultados são confirmados posteriormente por Nwani et al (2021), que aprovam o uso do teste de MN, tanto na avaliação da toxicidade de poluentes quanto no monitoramento de ecossistemas aquáticos. Portanto, os biomarcadores tornam-se ferramentas eficazes na estimativa de efeitos ecotoxicológicos, tanto em em estudos de campo, quanto de laboratório (BONIFACIO; HUED, 2019).…”

O uso de agrotóxicos no mundo, com vista a aumentar a produção de alimentos, deve ser acompanhado de protocolos de análise e monitoramento ambiental. O teste de micronúcleo (MN) utiliza peixes como modelo, porque eles respondem à contaminação das águas com reações rápidas mesmo em baixas concentrações. Essa pesquisa teve por objetivo identificar em periódicos publicados, entre janeiro de 2000 a junho de 2021, através de palavras-chave pré-estabelecidas, artigos que usaram o protocolo de MN em peixes e determinar a existência de relação entre o uso de agrotóxicos e a ocorrência de alterações genotóxicas em eritrócitos de peixes, por meio de uma revisão integrativa. Como resultado permaneceram 149 artigos. A espécie Channa punctatus teve a maior (11,4%) frequência. Experimentos controlados foram os mais frequentes. O marcador MN é eficiente para avaliar o potencial genotóxico em peixes expostos à inúmeros agrotóxicos, porém sem uma padronização nos testes.

The reduction in agricultural production due to the negative impact of insects and weeds, as well as the health and economic burden associated with vector-borne diseases, has promoted the wide use of chemicals that control these “enemies.” However, the use of these synthetic chemicals has been recognized to elicit negative impacts on the environment as well as the health and wellbeing of man. In this study, we presented an overview of recent updates on the environmental and health impacts of synthetic pesticides against agro-pest and disease vectors while exhaustive reviewing the potentials of natural plant products from Zanthoxylum species (Rutaceae) as sustainable alternatives. This study is expected to spur further research on exploiting these plants and their chemicals as safe and effective pesticide entities to minimize the impact of their chemical and synthetic counterparts on health and the environment.
