Dissolved organic carbon (DOC) is critically important in the chemistry of freshwater. It complexes heavy metals, making them less bioavailable to aquatic organisms, and absorbs and attenuates UVB radiation, undergoing degradation and alteration in the process. This study examined changes in metal toxicity to the freshwater green alga Pseudokirchneriella subcapitata in high- and low-DOC natural...
Cave Drip Water-Related Samples as a Natural Environment for Aromatic Hydrocarbon-Degrading Bacteria
Inactivation of bacteriophage MS2 by reactive oxygen species (ROS) and triplet excited state of dissolved organic matter ((3)DOM*) produced by irradiation of natural and synthetic sensitizers with simulated sunlight of wavelengths greater than 320 nm was investigated. Natural sensitizers included purified DOM isolates obtained from wastewater and river waters, and water samples collected from S...
Groundwater aquifers as one of the main sources of water supplies are faced with different risks such as level dropping due to lack of precipitation, and natural and non-natural pollutants. Thus, it is extremely necessary to monitor ground water quality. In the present study, the concentration of cations, anions, and some toxic metals was evaluated in 21 rural water supplies in Qorveh plain in ...
