Accumulation of metals in plant tissues, and occasionally, different cells of the same tissue, may be highly non-uniform (Seregin and Kozhevnikova, 2008). Easy-to-use histochemical methods may greatly help to investigate the distribution and accumulation of metals within and among plant tissues, and also provide information on their subcellular localization (Seregin and Kozhevnikova, 2011).
Boreholes satellite image. 2.2. Analysis of water Samples directed to heavy metals determination were filtered through a < 0, 45 µm pore-size membrane filters. The pH of the filtrate was set to 2 ± 0, 2 with the ultrapure HNO 3 (Merck 65%) and stored at 4 C° until the analysis.

Cadmium is one of the most toxic heavy metals in the freshwater environment (IPCS, 1992). According to USEPA, (2005) the limit values of cadmium for aquatic life range between 0.00066-0.002 mg/L. According to done measurements, the cadmium concentration was higher than the above mentioned values in all the stations.

Cadmium was an exception to this rule, with concentrations in reservoirs and at localities being quite similar. Iron was another exception, with the result that some reservoirs had a slightly higher concentration than their fed localities, although this was not always the rule.
