Review of 15 Years of Research on Sediment Heavy Metal Contents and Sediment Nutrient Release in Inland Aquatic Ecosystems, Turkey

Turkey’s inland water ecosystem consists of 33 rivers (177.714 miles), 200 natural lakes (906.118 ha), 159 reservoirs (342.377 ha) and 750 ponds (15.500 ha). Sedimentological studies conducted on inland water ecosystems during the last 15 years in Turkey can be categorized into two main topics. The first group of studies is concerned with heavy metal levels in sediment, with especial reference ...

Studies of Radioactive Contaminations and Heavy Metal Contents in Vegetables and Fruit from Lublin, Poland

This paper presents studies of the level of some gamma radioactive elements and heavy metals in fruits, vegetables and plants from Lublin. Potassium K isotope was the most prevalent element in the examined samples. It concentrated mainly in aboveground parts of some vegetables, for example in parsley and carrots haulm and in leaves of red beet and leek (from 1135 to 1940 Bq/kg). Considerably lo...

Determination of Heavy Metal Contents in Samples of Medicinal Herbs

The heavy metals Cd, Pb, Zn, Ni and Mo were determined in 27 samples of medicinal herbs taken from various places in Bielsko Biata and the neighbouring area. Samples were digested by the wet method in a microwave oven. Flame AAS and differential pulse polarography (anodic and stripping voltammetry) were used for determination of these metals. Oriental tobacco (CTA-ATL-1) as the certified refere...

Assessment of Heavy Metal Contents of Some Indian Medicinal Plants

The present study was carried out to quantitatively analyze the levels of six potentially toxic heavy metals viz., arsenic (As), lead (Pb), cadmium (Cd), mercury (Hg), chromium (Cr) and nickel (Ni) in ten important Indian medicinal plants. The air dried powdered plant materials were subjected to microwave assisted wet digestion for the preparation of test samples. The samples were analyzed by u...
