Separation of heavy metal from water samples--The study of the synthesis of complex compounds of heavy metal with dithiocarbamates.

The toxicity and persistence of heavy metal (HM) ions may cause several problems to marine organisms and human beings. For this reason, it is growing the interest in the chemistry of sulphur donor ligands such as dithiocarbamates (DDTC), due to their applications particularly in analytical chemistry sciences. The aim of this work has been the study of heavy metal complexes with DDTC and their application in separation techniques for the preconcentration and/or removing of heavy metals from the water solutions or the water ecosystems prior to their analysis.

First survey of atmospheric heavy metal deposition in Kosovo using moss biomonitoring.

Bryophytes act as bioindicators and bioaccumulators of metal deposition in the environment. The atmospheric deposition of Cd, Cr, Cu, Fe, Hg, Ni, Mn, Pb, and Zn in Kosovo was investigated by using carpet-forming moss species (Pseudocleropodium purum and Hypnum cupressiforme) as bioindicators. This research is part of the European moss survey coordinated by the ICP Vegetation, an International Cooperative Programme reporting on the effects of air pollution on vegetation to the UNECE Convention on Long-range Transboundary Air Pollution.

Polymorphism of UGT1A1*28 (TA)7 and liver damage in hepatitis B virus-positive patients in Albania.

Hepatitis B virus (HBV) is the infectious agent of both acute and chronic hepatitis. HBV exists in multiple genotypic variants that differ in their capacity to become persistent chronic infections and in their clinical manifestations, including hepatocellular carcinoma. The 8 genotypes (A-H) of HBV show a specific worldwide geographic distribution and are correlated with different disease course, severity, and response to therapy.

4-Nitro-phenyl 2-bromo-2-methyl-propano-ate.

In the title compound, C(10)H(10)BrNO(4), the planes of the carboxyl-ate and nitro groups are rotated by 60.53 (13) and 6.4 (3)°, respectively, to the benzene ring.

3-Benzyl-3-hy-droxy-2-phenyl-3H-indole 1-oxide.

The asymmetric unit of the title compound, C(21)H(17)NO(2), contains two crystallographically independent mol-ecules of similar geometry. The indole ring systems form dihedral angles of 8.30 (5) and 9.
