قابلية الطحلب الأخضر Scendesmusdimorphus على المراكمة الحيوية لبعض العناصر الثقيلة و تأثيرها على أشكال خلاياه و محتوياتها

الملخص EN

The study was conducted to know the ability of the green alga Scendesmusdimorphus to accumulate four heavy elements were copper, lead, cadmium and nickel in four concentrations (5, 10, 15 and 20) mg / L for every one and then observed the effects of these elements on the shape of the cell and its internal structures by using the scanning electron microscopy technique.

The results were showing that the copper ion was the least severe effect on the form and content of algae as compared with the rest of the other elements, while cadmium was the most affect among the elements that were added.

The results of the absorption spectrum that the order of absorption of elements in terms of concentration was cadmium (0.78%) of the dry weight, followed by the copper percent (0.33%) of the dry weight, the nickel and its concentration (0.18%) of the dry weight while the lead element was the least accumulation, Its concentration was ( 0.10%) of dry weight.
