Marine Invertebrates as Bioindicators of Heavy Metal Pollution
Atmosphere, earth and water compose the environment. The presence of heavy metals in the environment has grown because of their large employment in some industrial and agricultural activities. Although these metals are terrestrial products, they flow into the sea through effluents and sewage or are directly discharged from industries placed on the seawater front. It should be considered that me...
متن کاملSpermatogenesis and karyotypes of three species of water striders (Gerridae, Heteroptera).
Although they are of economic importance, there have been few cytogenetic studies of the Gerridae (Heteroptera) in Brazil. We examined spermatogenesis (meiosis and spermiogenesis) and nucleolar behavior in three species of the family Gerridae. Brachymetra albinerva and Halobatopsis platensis were found to have a chromosome complement of 2n = 25 (24A + X0) and Cylindrostethus palmaris 2n = 29 (2...
متن کاملWater striders (family Gerridae): mercury sentinels in small freshwater ecosystems.
To circumvent some of the previous limitations associated with contaminant-monitoring programs, we tested the suitability of the water strider (Hemiptera: Gerridae) as a mercury sentinel by comparing total mercury concentrations in water striders and brook trout (Salvelinus fontinalis) from a variety of stream sites in New Brunswick, Canada. There was a strong association between the two variab...

Abstract Heavy metals have raised one of the most important problems in ecology and organisms life especially human being and animals. A variety of indicators including tissues of fish, birds and sediment have been used recently to measure the aquatic pollution with heavy metals. The aim of this study was to search the published articles in Iran a...
