The Effects of Heavy Metals on Aquatic Animals

  title={The Effects of Heavy Metals on Aquatic Animals},
  author={Jina Khayatzadeh and Abbasi},
Heavy metals consist less than one percent of living mass organisms, and their different density cause to some disorders. Surface waters and also acidic rains can transfer these metals to oceans via washing polluted environment. Heavy metals naturally exist in very little amount in watery places. Metals pollution of the sea is less than other types of watery pollution but its effects on marine ecosystems and humans are very extensive. Industrial wastes in aquiculture cause toxic effects in… 

A Review on the Effects of Heavy Metals on Aquatic Animals

The development of industries and the uncontrolled increase of population, the development of agricultural areas and the use of fertilizers and pesticides have caused industrial and municipal

Bioaccumulation of Cadmium in Freshwater Fish: An Environmental Perspective

This review briefly addresses the Cd emission sources, uptake and impacts of Cd on freshwater fish and bioaccumulation nature of CD by emphasizing the CD accumulation affinity in freshwater fish tissues.

Evaluation of Heavy Metals Concentration and Its Consumption Risk in Trout Fish (Oncorhynchus Mykiss)

The average concentration of Copper, Iron, Zinc, Nickel and Magnesium in muscle tissue of rainbow trout compared to international standards, is slightly lower than that at current consumption rates, long-term health risks to consumers is realized.

Heavy Metals Assessment in the Macrophytes of Viroi Lake

Macrophytes are considered as important component of the aquatic ecosystem since they serve as food source for aquatic invertebrates and can act as efficient accumulator of heavy metals. Current

Bioaccumulation of cadmium in fish and human health risk assessment

Cadmium is a toxic heavy metal and can cause harm to both aquatic organisms and human being. Several anthropogenic activities result in the release of Cd in the environment. It eventually goes to the

Determination of the Toxicity Cause by Trace Metals on Zebrafish (Danio rerio) Embryo

Water quality deterioration due to inorganic and organic pollutant is a serious issue and the presence of toxic trace metals cause a serious threat to the aquatic ecosystem. Fish embryos have gained

Impact of metal pollution, food availability, and excessive fishing on Rhabdosargus haffara stock (family: Sparidae) in Timsah lake

The results revealed that haffara stock at lake Timsah is overfished, and the estimated precautionary target reference points advised the reduction of fishing effort by about 30–50 %.

Heavy metal exposure and behavioral assessment of vultures in a captive environment

Heavy metals are a heterogeneous group of metals that can cause detrimental biological disruptions in vultures. Heavy metals play a threatening role and affect vulture populations around the globe.



Effect of Environmental Pollution by Phenol on Some Physiological Parameters of Oreochromis niloticus

Phenolic compounds are common water pollutants and include wide variety of organic chemicals. In Egypt, effluents of oil refineries contain phenol and the receiving waters are therefore subjected to

Analysis of heavy metals in water, sediments and fish samples of Madivala lakes of Bangalore, Karnataka.

Heavy metal (Pb, Cd, Cr, Ni ) concentration in water sediments and fish was analysed from Madivala lake in the month of June 2008. There was an appreciable increase in metal concentrations in going

Heavy Metals in Eleven Common Species of Fish from the Gulf of Aqaba, Red Sea

The muscles, livers, gills, gonads, and stomachs of eleven common fish species collected at three sites in the northern Gulf of Aqaba, were analyzed for the heavy metals Cd, Co, Cr, Cu, Fe, Mn, Ni,

A review on phytoremediation of heavy metals and utilization of its byproducts.

The mobility, bioavaliability and plant response to presence of soil heavy metals, classifies the plants according to phytoextraction mechanism and discusses the pathway of metal in plants.


The aim of the present investigation was to determine the effect of heavy metal pollutants such as cadmium, chromium, nickel and lead in aquatic system on common carp (Cyprinus carpio L.) by using a

Effect of transplantation on heavy metal concentrations in commercial clams of Lake Timsah, Suez Canal, Egypt

Ruditapes decussatus and Venerupis pullastra are commercially fished clams with a wide distribution in the shallow inshore waters of Lake Timsah, Egypt. They are usually contaminated with heavy


Cercarial shedding by infected snails was significantly reduced in the presence of heavy metals and by 6 wks shedding had ceased at the highest metal concentrations, indicating a significant interaction between heavy metal exposure and infection.

Effect of water pollution on expression of immune response genes of Solea aegyptiaca in Lake Qarun

The differential expression of the immune genes, that is, GARP and SIMP genes, as a result of pollution influence was further confirmed by RT-PCR, with the up-regulation of these genes in the liver of the collected fish.

Accumulation and Depuration of Heavy Metals in The Hard Clam (Meretrix meretrix) under Laboratory Conditions

Heavy metal accumulation and depuration may alter the effectiveness of Meretrix meretrix as a biomonitoring organism for water quality assessment. Therefore, this study was conducted to evaluate the
