Abstract

This study investigates aberrations caused by barium and vanadium on meristematic cells of Lens culinaris Medik. Barium and vanadium ions at various concentrations (0.05?M, 0.1?M, 0.25?M, 0.5?M, and 1.0?M) were exposed to the seeds of the plant at fixed time interval (12?h). After seedlings, with a microscopic examination images were captured about the root tips. Those images showed that several abnormalities occurred on the plant such as chromosome breakings, chromosome dispersion, bridge chromosome, chromosome adherence, ring chromosome. Variety and number of abnormalities were counted and compared to each other statistically. The results show an increase in abnormalities caused by for both ions with increasing treatment time. Chromosome adherence and chromosome breaking have reverse relationship in which number of occurrence for one of them decreases with increase on other one. Fish bone and chromosome adherence have a positive relationship in which number of one increases with the raise in other's number. Exposed metals have caused formation of ligands with proteins which can prevent the persistence of metal ions in DNA protein cross-links that are involved in DNA formation process.

Barium

56 Ba 137.327000000 Barium

See more Barium products. Barium (atomic symbol: Ba, atomic number: 56) is a Block S, Group 2, Period 6 element with an atomic weight of 137.27. The number of electrons in each of barium's shells is [2, 8, 18, 18, 8, 2] and its electron configuration is [Xe] 6s2. Barium Bohr ModelBarium is a member of the alkaline-earth metals. The barium atom has a radius of 222 pm and a Van der Waals radius of 268 pm. Barium was discovered by Carl Wilhelm Scheele in 1772 and first isolated by Humphry Davy in 1808. Elemental BariumIn its elemental form, barium is a soft, silvery-gray metal. Industrial applications for barium include acting as a "getter," or unwanted gas remover, for vacuum tubes, and as an additive to steel and cast iron. Barium is also alloyed with silicon and aluminum in load-bearing alloys. The main commercial source of barium is the mineral barite (BaSO4); it does not occur naturally as a free element . The name barium is derived from the Greek word "barys," meaning heavy.

Vanadium

23 V 50.941500000 Vanadium

See more Vanadium products. Vanadium (atomic symbol: V, atomic number: 23) is a Block D, Group 5, Period 4 element with an atomic weight of 50.9415. Vanadium Bohr ModelThe number of electrons in each of Vanadium's shells is 2, 8, 11, 2 and its electron configuration is [Ar] 3d3 4s2. The vanadium atom has a radius of 134 pm and a Van der Waals radius of 179 pm. Vanadium was discovered by Andres Manuel del Rio in 1801 and first isolated by Nils Gabriel Sefström in 1830. In its elemental form, vanadium has a bluish-silver appearance. Elemental VanadiumIt is a hard, ductile transition metal that is primarily used as a steel additive and in alloys such as Titanium-6AL-4V, which is composed of titanium, aluminum, and vanadium and is the most common titanium alloy commercially produced. Vanadium is found in fossil fuel deposits and 65 different minerals. Vanadium is not found free in nature; however, once isolated it forms an oxide layer that stabilizes the free metal against further oxidation. Vanadium was named after the word "Vanadis" meaning goddess of beauty in Scandinavian mythology.
