Evaluation of Heavy Metal Pollution in Anzali Wetland, Guilan, Iran
Background: Evaluation of heavy metals as toxic pollutants in environment has a significant importance in environmental pollution studies. surficial sediments of water resources have a high potential in releasing heavy metals to the upper water environment, hence sediment analysis presents guidelines to the authorities for monitoring the environmental systems. Methods: In this study, total an...
متن کاملEvaluation of Heavy Metal Dust Pollution and their Origin in the Atmosphere of Kuhdasht, Lorestan Province
Dust is one of the environmental hazards in arid and semi-arid regions of the world. In some areas, under the influence of human activities, dust is contaminated by heavy metals. In this study, the dust of 10 stations in the Kuhdasht region of Lorestan province in four seasons of spring, summer, autumn, and winter, as well as adjacent surface soils (a total of 40 dust samples and 10 surface soi...
متن کاملSpeciation Studies and Toxicity Assessment of Complex Heavy Metal Mixtures
The MicrotoxTM bioassay and polarographic techniques were used together to identify specific oxidation states and toxicity of metals. The bioassay is based on light reduction by bioluminescent bacteria upon exposure to toxicants. In polarography, a mercury drop substrate’s potential is changed, and the substance of interest is electrochemically reduced. Reduction current is proportional to its ...
متن کاملEvaluation of heavy metal pollution in sediments, water and macrobenthos of Hur Al-Azim wetland (Khuzestan)
Background and Objectives: Chemical storage of water cannot provide complete information about the extent of bioavailability of metals in the environment, while the study of this storage in the chain of water, sediment and macrobenthos can make the rate of rotation and storage risk more visible in ecosystems. Hur Al-Azim wetland is located in the west of Khuzestan Province. Large parts of it ha...
متن کاملDevelopmental phytotoxicity of metal oxide nanoparticles to Arabidopsis thaliana.
Phytotoxicity is an important consideration to understand the potential environmental impacts of manufactured nanomaterials. Here, we report on the effects of four metal oxide nanoparticles, aluminum oxide (nAl(2)O(3)), silicon dioxide (nSiO(2)), magnetite (nFe(3)O(4)), and zinc oxide (nZnO), on the development of Arabidopsis thaliana (Mouse-ear cress). Three toxicity indicators (seed germinati...
