Mutagenic effects of mercury pollution as revealed by micronucleus test on three Amazonian fish species.
Genotoxic effect of mercury pollution over Amazonian fish species was evaluated by using the micronucleus test (MNT). Distinct mean frequencies of micronuclei (MN) were observed in three trophically distinct characin fish species collected in two riverine environments in the Amazon Basin: the Madeira (polluted area) and the Solimões (unpolluted area) rivers. Mean frequencies of MN observed in P...
متن کاملFlood volcanism in the northern high latitudes of Mercury revealed by MESSENGER.
MESSENGER observations from Mercury orbit reveal that a large contiguous expanse of smooth plains covers much of Mercury's high northern latitudes and occupies more than 6% of the planet's surface area. These plains are smooth, embay other landforms, are distinct in color, show several flow features, and partially or completely bury impact craters, the sizes of which indicate plains thicknesses...
متن کاملMercury toxicity
Mercury is a metal found in elemental, organic, and inorganic forms in the nature. This substance is present in the composition of earth crust, soil, air, and even in some tissues of plants and sea animals. Each year nearly 3400 tons of mercury compounds are released in the environment, which 95% settle in the soil, 3% in the oceans, and 2% in the atmosphere. Different industrial products li...
متن کاملEvaluating Total Mercury and Methyl Mercury Contents in Canned Tuna Fish of the Persian Gulf
Due to hygienic risks of mercury residues in food and marine originated supplements, measuring total mercury and methyl mercury contents of canned tuna as a highly consumable marine food product is essential. In this study, 40 canned Tuna fish (from Persian Gulf) were collected in 2015 and then flame atomic absorption spectrometer (FAAS) and thermo gas chromatography mass spectrophotometry were...
متن کاملEquation of State for Mercury
An analytical equation of state by Song and Mason is developed to calculate the PVT properties ofmercury. The equation of state is based on the statistical-mechanical perturbation theory of hard convexbodies and can be written as a fifth-order polynomial in the density. There exists three temperaturedependentparameters in the equation of state; the second virial coefficient, an effective molecu...
