To evaluate the marine heavy metal pollution, Hg, Zn, Pb, Cd, Cr of bivalves and fishes collected from cultivating areas and natural catching along Lianyungang coastal waters were analyzed. Results show that Hg, Zn, Pb, Cd were present in the marine organisms except Cr below the detection limits. The content of Pb of bivalves from cultivating areas and that of bivalves and fishes from natural catching exceeded the standards, while the rest was below the prescribed legal limit, indicating that Pb has become the potential health risks. Anthropogenic activities may have introduced significant amounts of Pb into the marine environment.

The aim of this paper was the application of statistical analysis including principal component analysis to evaluate heavy metal pollution obtained by moss technique in the air of Ha Noi and its surrounding areas and to evaluate potential pollution sources. The concentrations of 33 heavy metal elements in 27 samples of Barbula Indica moss in the investigated region collected in December of 2016 in the investigated area have been examined using multivariate statistical analysis. Five factors explaining 80% of the total variance were identified and their potential sources have been discussed.
