Heavy Metals Pollution

The problem of urban soil pollution has become increasingly prominent. Finding out the source of contamination of the replaced soil, analyzing the potential threat of contaminated soil to human health and ecological environment are the focus and the premise of the urban land replacement work. This paper selected typical region in eastern coast of Jiaozhou Bay, and research of replaced soil was carried out from the analysis of heavy metals pollution and ecological risk assessment. The results show that in the study site the quality of soil environment is poor, and there is a certain degree of heavy metals pollution; Pb,Ni and Cu are the main contribution factors of the ecological risk.

Active Compounds

The occurrence and distribution of 110 pharmaceutically active compounds (PhACs) were investigated in snow near Jiaozhou Bay (JZB), North China. All target substances were analyzed using solid phase extraction followed by liquid chromatography coupled to tandem mass spectrometry.A total of 38 compounds were detected for the first time in snow, including 23 antibiotics, eight hormones, three nonsteroidal anti-inflammatory drugs, two antipsychotics, one beta-adrenergic receptor and one hypoglycemic drug. The total concentration of PhACs in snow ranged from 52.80 ng/L to 1616.02 ng/L. The compounds found at the highest mean concentrations included tetracycline (125.81 ng/L), desacetylcefotaxime (17.73 ng/L), ronidazole (8.79 ng/L) and triamcinolone diacetate (2.84 ng/L). The contribution of PhACs in the vicinity of JZB to the PhACs in the snow is far greater than the contribution of those transmitted over a long distance. PhACs are mainly derived from drugs applied to local humans and animals. Based on the individual risk quotient (RQ) values, tetracycline poses high risks to the relevant aquatic organisms (algae and invertebrates). The rational application and scientific management of PhACs is an effective approach to reduce the ecological risks in JZB.
