Evaluation of bioaccumulation of lead metal pollutant in two biotic and abiotic compartments of the Caspian Sea coastal sediments
Bioaccumulation of heavy metals in food chains is one of the most important environmental and health problems of aquatic ecosystems. The aim of the present study was to evaluate the amount of lead metal uptake by Gammarus sp. And sedimentation took place in the coastal region of Sisangan in the Caspian Sea. In this study Gammarus sp. As the predominant benthic in soft sediments as a biological ...
متن کاملBiogeography of planktonic and benthic cyanobacteria in coastal waters of the Big Island, Hawai'i.
Cyanobacteria are biogeochemically significant constituents of coral reef ecosystems; however, little is known about biotic and abiotic factors influencing the abundance and composition of cyanobacterial communities in fringing coral reef waters. To understand the patterns of cyanobacterial biogeography in relation to coastal environmental factors, we examined the diversity of planktonic and be...
متن کاملMercury in coastal watersheds along the Chinese Northern Bohai and Yellow Seas.
The concentration of total mercury [Hg] in waters, sediments and biota (carp and crabs) as well as the concentration of methyl mercury [MeHg] in biota from upstream (surface water systems) and downstream (coastal and estuarine systems) areas within coastal watersheds along the Chinese Northern Bohai and Yellow Seas were investigated. In most waters tested, the [Hg] could have adverse effects on...
متن کاملPhytoplankton Community and Physical-Chemical Characteristics of Seawater in the Bandar Abbas Coastal Water, Persian Gulf: An Environmental and Process Perspective
Seawater ecosystems are controlled by multitude various abiotic and biotic factors. These factors also affect the activities of coastal human communities and installations including coastal desalination plants. This research investigated a point environmental (physical and chemical) and biological (phytoplankton) parameters of Bandar Abbas coastal water in 3 depth layers of 1, 5 and 10 m carrie...
متن کاملScale characteristics of the bloom event: A case study in the Iranian coastal waters of the Southern Caspian Sea
Nutrient enrichment in water and sediments due to excessive anthropogenic activities in recent years has caused excessive algal growth in the Caspian Sea. The current study was conducted to determine the abundance of phytoplankton community, the dominant species and chlorophyll-a [Chl-a] concentration during algal blooms in the Iranian coastal waters of Caspian Sea through four seasons from 201...
