Heavy metals accumulation in some important fish species cultured in commercial fish farm of Natore, Bangladesh and possible health risk evaluation

Emerging contaminants, Journal Year: 2023, Volume and Issue: 9(4), P. 100254 - 100254

Published: Aug. 2, 2023

Heavy metal contamination in aquatic environment is a serious concern throughout the world. Metal are responsible for accumulation of metals within fish body. And, consumption these contaminated possess threat to associated consumers. In this current study, five commonly cultured freshwater fishes (rui, Labeo rohita; mrigal, Cirrhinus mrigala; silver carp, Hypophthalmicthys molitrix; bata, and sarpunti, Puntius sarana) were collected from commercial farm Natore district, Bangladesh analyze levels edible portion (flesh), assess human health risk. Several heavy such as zinc (Zn); cadmium (Cd); chromium (Cr); arsenic (As); lead (Pb); nickel (Ni) analyzed by flame atomic absorption spectrophotometer. Besides, target hazard quotient (THQ), index (HI) lifetime cancer risk (TR) also estimated assessing concentrations Zn, Cd, Cr, As, Pb Ni different species found 6.36 ± 1.48 13.31 1.33; 0.017 0.01 0.049 0.02; 0.654 0.04; 0.015 0.033 0.01; 0.534 0.11 0.08 0.05, respectively. All values recommended level except Cr C. mrigala. The THQ, HI TR all indicated that no resulting those fishes. Therefore, study revealed area might be free hence, safe consumption.

The Egyptian Journal of Aquatic Research, Journal Year: 2024, Volume and Issue: 50(2), P. 169 - 182

Published: May 31, 2024

Biomarkers play a pivotal role in monitoring the ecological integrity of aquatic environments. They offer valuable insights into impacts pollutants and environmental stressors on health ecosystems. By assessing changes biomarker levels or activities, scientists can effectively identify quantify exposure to effects contaminants. This review illustrates different types classes biomarkers their application understanding how affect organisms at molecular, cellular, organismal levels. In addition, integrating with assessments is discussed, emphasizing importance considering multiple biological organization monitoring. Additionally, this discusses recent advancements research through development novel biomarkers, integration omics technologies, bioinformatics, real-time monitoring, assessments, risk assessment management.

Detection of Arsenic, Chromium, Cadmium, Lead, and Mercury in Fish: Effects on the Sustainable and Healthy Development of Aquatic Life and Human Consumers

Sustainability, Journal Year: 2023, Volume and Issue: 15(23), P. 16242 - 16242

Heavy metals are among the most important pollutants that threaten aquatic environment when their concentrations exceed certain limits. Some of these and metalloids beneficial necessary for fish, but others, such as arsenic (As), chromium (Cr), cadmium (Cd), lead (Pb) mercury (Hg), non-essential toxic. In reviewing recent relevant literature, 4 different continents, 13 countries, more than 50 fish species were analyzed in terms As, Cr, Cd, Pb Hg concentrations. According to comparative results, it was found Tercan Dam Lake, Turkey, highest concentration Cr detected Capoeta umbla (2.455 mg/kg), As Ctenopharyngodon idella (0.774 mg/kg) species.

Fish as a Sustainable Biomonitoring Tool in Aquatic Environments

Published: Jan. 1, 2024

Biomonitoring involves the use of biological organisms to detect or measure presence various toxic substances rather on land in water. Fish resides aquatic environments and its position at top food chain has made it a useful tool for biomonitoring. They can easily accumulate pollutants that are bio-available environment, most especially their gills. The composition, abundance, distribution fish species give potential indication condition environments. Other such as crustaceans, zooplankton, macro micro invertebrates also be used because they ubiquitous. is principally dictated by effects land-based activities, which affect water quality composition. Humans other hand exposed bio-accumulated when plants consumed from polluted In lieu this, therefore essential sustainably biomonitor environments, either with tool.
