Determination Of Mercury Levels In Edible Tissues Of Various Fish Samples From Sır Dam Lake, Özlem Turgay
Determination Of Mercury Levels In Edible Tissues Of Various Fish Samples From Sır Dam Lake, Özlem Turgay
Turkish Journal of Biology
Mercury (Hg) levels in Cyprinus carpio (carp) (n: 20) and Siluris glanis (wels) (n: 13) from Sır Dam Lake, Kahramanmaraş, were measured during 2002 and 2003. The fish samples were obtained from fishermen. Hg levels ranged from 0.03 to 0.18 µg/g dry weight in carp samples and from 0.16 to 0.38 µg/g dry weight in wels samples. Even though no high levels of Hg were determined in the fish, a possible hazard may occur in the future depending on the agricultural and industrial development in this area.
Comparative Genotoxic Potential Of Mercury And Cadmium In Soybean, Girjesh Kumar, Priyanka Rai
Comparative Genotoxic Potential Of Mercury And Cadmium In Soybean, Girjesh Kumar, Priyanka Rai
Turkish Journal of Biology
Genotoxic effects of two heavy metals viz. mercury (Hg) and cadmium (Cd) on somatic and gametic cells of soybean were investigated. Seeds were treated with different doses of these heavy metals. Treatments with Hg and Cd not only reduced the frequency of dividing cells but a wide spectrum of chromosomal abnormalities were also recorded. Pollen fertility was found to be significantly correlated with meiotic irregularities found in the metal treatment sets. It was found that both of these heavy metals are capable of inducing chromosomal aberrations, but Hg is much more genotoxic than Cd, since it induces greater abnormalities.
