Abstract Pesticides and heavy metals are considered as potent contaminants in aquatic environment. Both sourced into the ecosystems by various types of anthropogenic well natural practices. Such contamination drastically affect normal activity associated living organisms particularly fish. pesticides toxicity cause several negative effects on fish growth, physiology, immune response, reproduction, embryonic larval development different histopathology major organs including gill, kidney, liver, gonads, intestine. Besides, consumption contaminated poses a serious health concern to consumers. Considering these issues, current review is designed investigate toxic aspects fishes along with their possible sources, types, mode action role medicinal herbs mitigate toxicity.

Chitosan was hydro-thermally extracted from grey shrimp carapaces and characterized using various techniques (degree of deacetylation (DD), viscosity, thermogravimetric analysis (TGA), scanning electron microscopy (SEM), surface area (BET)). It then used for Cu(II) removal in a batch system, achieving maximum capacity 89 mg/g under standard conditions. Both pseudo-first-order pseudo-second-order nonlinear kinetic models described the adsorption ions on chitosan well, with better fit model at low concentrations, while equilibrium data suggested that Langmuir suitable describing 123 mg/g. A response methodology central composite design were to optimise evaluate effects six independent parameters: initial concentration, pH, concentration (S/L), temperature (T), contact time (t), NaCl efficiency by synthesised chitosan.

Abstract Background Pollution with heavy metals (HMs) is time- and concentration-dependent. Lead zinc pollute the aquatic environment, causing severe health issues in animals. Materials methods Nile tilapia, predominant cultured fish Egypt, were experimentally exposed to 10% of LC 50 lead nitrate (PbNO 3 ) sulfate (ZnSO 4 ). Samples collected three different periods, 4, 6, 8 weeks, addition a trial treat experimental infected Aeromonas hydrophila , an antibiotic (florfenicol). Results Liver enzymes linearly upsurged time-dependent manner response HMs exposure. ALT was 92.1 IU/l AST 82.53 after eight weeks. In eighth week exposure, hepatic tissue, levels glutathione peroxidase (GPx), catalase (CAT), metallothionein (MT) increased 117.8 U/mg prot, 72.2 154.5 respectively. On exposure HMs, gene expressions some cytokines downregulated compared control.

This study investigated the level Labeo rohita Mystus seenghala from River Jhelum district Khushab, Punjab, Pakistan. concentration calcium, magnesium, iron, nickel, copper, arsenic, cadmium, zinc, chromium, manganese, cobalt, lead gills, liver, muscle tissues these fish was measured using inductively coupled plasma-mass spectrometry. Then, extent contamination possible risks were assayed. Our findings indicate significant variations elemental metal concentrations among different organs between species, reflecting their diverse feeding habits habitats. risk assessment based estimated daily intake, weekly maximum permissible target hazard quotient, index or total index, cancer revealed consumers fish. emphasizes need for continuous monitoring, as new data insights are crucial understanding mitigating risks.

Metal pollution is a major environmental concern worldwide, especially in Egypt. The aquaculture industry uses widespread artificial feeds to stimulate fish production, leading metal accumulation the aquatic environment. Heavy concentrations (HMCs) sediments, water, and tissues were studied study effect of levels on heamatological, biochemical, immunological aspects farmed as well human health. Results declared that HMC water sediment significantly different between El-Sharkia Kafr El-Sheikh fishponds (T-test, p < 0.05). This was supported by index sediment, indicating (ES fishponds) more contaminated than (KES fishponds). Also, HMCs increased cultivated ES KES fishponds.
