The main formation condition and harmfulness of the acidic mining waste water's were analyzed in this paper. The treatment technology of the acid mine drainage's was briefly introduced. The research development of acid mine drainage was summarized in recent years. It was the fact that developing the efficient, cheap, safe and easy treatment technology of acid mine should be necessary and inevitably and some success management experiences of acidic waste water were applied in acidic mining wastewater.

Abstract. Cardiopulmonary health implications resulting from exposure to secondary organic aerosols (SOA), which comprise a significant fraction of ambient particulate matter (PM), have received increasing interest in recent years. In this study, alveolar macrophages were exposed to SOA generated from the photooxidation of biogenic and anthropogenic precursors (isoprene, α-pinene, β-caryophyllene, pentadecane, m-xylene, and naphthalene) under different formation conditions (RO2 + HO2 vs. RO2 + NO dominant, dry vs. humid). Various cellular responses were measured, including reactive oxygen and nitrogen species (ROS/RNS) production and secreted levels of cytokines, tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6). SOA precursor identity and formation condition affected all measured responses in a hydrocarbon-specific manner. With the exception of naphthalene SOA, cellular responses followed a trend where TNF-α levels reached a plateau with increasing IL-6 levels. ROS/RNS levels were consistent with relative levels of TNF-α and IL-6, due to their respective inflammatory and anti-inflammatory effects. Exposure to naphthalene SOA, whose aromatic-ring-containing products may trigger different cellular pathways, induced higher levels of TNF-α and ROS/RNS than suggested by the trend. Distinct cellular response patterns were identified for hydrocarbons whose photooxidation products shared similar chemical functionalities and structures, which suggests that the chemical structure (carbon chain length and functionalities) of photooxidation products may be important for determining cellular effects. A positive nonlinear correlation was also detected between ROS/RNS levels and previously measured DTT (dithiothreitol) activities for SOA samples. In the context of ambient samples collected during summer and winter in the greater Atlanta area, all laboratory-generated SOA produced similar or higher levels of ROS/RNS and DTT activities. These results suggest that the health effects of SOA are important considerations for understanding the health implications of ambient aerosols.

Formation Conditions

It is well known that scale layer on work roll forms in hot sheet rolling of steel and scale layer on work roll plays an important role for hot rolling process. The formation conditions of scale layer on work roll are slightly known qualitatively and are hardly understood quantitatively. In order to investigate quantitatively the conditions of scale formation, three steels with different Si content are used and the slip rolling is carried out at a constant roll speed changing the scale thickness of steel workpiece and the reduction. The formation conditions of scale layer on work roll are examined quantitatively by observation of work roll surface after slip rolling. The experiments are carried out at constant rolling conditions of a velocity ratio of 20, a rolling speed of 50 m/min and a furnace temperature of 800 °C, changing the rolling reductions of 0.3, 0.5 and 1.0 mm and scale thickness of workpiece. The colza oil is used as base oil. The emulsion concentration is 3.0%. The emulsion temperature is controlled at 40 °C. Scale layer on work roll forms easily with increasing rolling reduction and decreasing scale thickness of workpiece for three steels A, B and C. In order to estimate quantitatively the formation condition of scale layer on work roll, parameter α which is given by a ratio of the rolling reduction to scale thickness of workpiece is proposed. Scale layer on work roll forms when values of parameter α become same for each steels. Values of parameter α become larger in order of steels A, B and C and it can be understood that scale layer on work roll forms easily in order of steels A, B and C. When FeO layer in scale of the steel surface adheres on work roll surface, it is expected that scale layer on work roll forms easily and strongly by transformation from FeO to Fe3O4, considering that the chemical composition of scale layer on work roll is Fe3O4.
