Research ArticleOpen accessEvery word in the titleACCUMULATION OF RADIONUCLIDES BY PYLAISIELLA MOSS (PYLAISIA POLYANTHA) UNDER URBOECOSYSTEM CONDITIONST. V. Varduni, T. M. Minkina, E. A. Buraeva et al.Contamination of environment by radionuclides in territories under urboecosystem conditions is actual problem. The search of new express methods for radioactivity determination of environment is important task of research. In present work it was shown that mosses are bioindicators of radioactive contamination, because they accumulate radioactive substances in high concentrations. Using of bryoindication methods are promising techniques for the assessment … …American Journal of Applied Sciences, Vol. 11, Issue 10 · 1 Dec 2014 · 6,450 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLimnological Studies on the Wetland Lake, Al-Asfar, with Special References to Heavy Metal Accumulation by FishGehan H. Fahmy, Adel A. FathiProblem statement: Al-Asfar Lake is one from the important shallow wetland lakes. It is located on the eastern region of Saudi Arabia, Al-Hassa Province.
