Garlic and Chlorella Biomodulate Lead Toxicity on Manganese Homeostasis in Carassius gibelio Bloch

Abstract

Environmental pollution negatively affects the aquatic ecosystems. Heavy metals are considered dangerous toxic elements for aquatic biota, as metallic elements or as salts which exhibit great stability. Among these, lead is toxic for all aquatic biotic components. Our research investigated the manganese distribution in tissue of Prussian carp fishes after lead intoxication, highlighted also the lead detoxifying potential of active principles from garlic and chlorella (powder). For our experiment 120 Prussian carp fingerlings, weighing 22-25g each, for 21 consecutive days, were divided according to the following treatments: C group (without treatment), E1 group (75ppm Pb in water as Pb(NO3)2 x �H2O), E2 group (75ppm Pb in water+2% freeze-dry garlic in feed), E3 group (75ppm Pb in water+2% freeze-dry chlorella in feed). At the end of the experimental period, tissue samples (gills, muscle myotomers�epaxial, heart, skin and scales, intestine, liver, brain, gonads, kidney) were collected after euthanasia with clove oil. Manganese concentration was analytical performed using AAS (atomic absorption spectrometry). Using fish as bioindicators of lead experimental contamination allowed us to obtain valuable informations about its ability to substitut/remove bioactiv minerals from animal tisssues. In the same time, we could emphasize the efficiency of natural antioxidants or chelators of edible plants (such as garlic) or algae (such as chlorella), to alleviat the lead impact on homeostasis of trace elements from tissues.

Natural Antioxidants can Improve Microplastics-Induced Male Reproductive Impairment in the African Catfish (Clarias Gariepinus)

“…Applications of microalgae supplementation have been developed recently; for instance, Chlorella vulgaris has established to develop, immunity, aquatic remedy, stress enhancement, and disease resistance in fish (Nicula et al, 2018;Mekkawy et al, 2020;Sahin et al, 2014). C. vulgaris used as feed supplementation alleviated the negative effect of chlorpyrifos (CPF) exposure and maintained the growth performance and biochemical parameters (Abu-Srea et al, 2018) ,also, C. vulgaris modulated the expression of genes encoding antioxidant enzymes and stress immune-related genes (Zahran et al, 2020) in the Nile tilapia.…”

“…Like other substances, also Aloe ferox can determine the occurrence of acute or chronic diseases, depending on the dose, the administration duration, and the reaction of the body. [34] One of these plants' side effects is hepatic and renal insufficiency. In literature is described a case of a 47 years old man from Soweto, South Africa who developed acute oliguric renal failure and liver dysfunction after ingestion of an herbal remedy.…”

“…Uranium mining activity continues to be a major source of radioactive environmental pollution by producing huge amounts of low radioactive wastes heaped around the mining galleries and large quantities of wastewaters [1]. It is also present in the sea-water and it can contaminate the fish [2]. The radioactive pollution is also faced by other countries such as Serbia in the spa waters [3], Greece in the Axios River's case [4] and Italy in the building materials [5].…”
