Concentration distributions of heavy metals and polycyclic aromatic hydrocarbons (PAHs) were determined in sediments taken in the Oyster Grounds. Average concentrations in fine fraction (<63 ?m) of the sediments of Cd, Cu, Hg, Pb, and Zn were 0.14, 21.8, 0.23, 49.2, and 118 ?g g?1, respectively. Average ?PAH concentration was 1.82 ?g g?1. Vertical gradients within the sediment cores varied for all compounds and did not exhibit any one particular trend, probably because of bioturbation and extensive fishery in this highly productive area. A highly significant north to south trend appeared for Cd: average values increased from 0.06 ?g g?1 in the northern part to 0.42 ?g g?1 in the southern. Most of the PAHs showed an opposite gradient: average ?PAH values decreased from 2.53 ?g g?1 in the north to 1.24 ?g g?1 in the southern part of the Oyster Grounds. Heavy-metal levels in Oyster Ground sediments were 5 to 10 times lower than in other North Sea sedimentation areas (e.g. the Wadden Sea and the German Bight) and in the river Rhine. The yearly sediment deposition in the muddy part of the Oyster Grounds was used to calculate the yearly load of the various heavy metals and PAHs. It was estimated that less than 0.03 to 0.3% of the total heavy-metal input to the North Sea reaches the sediments of the Oyster Grounds. 5 pp., 4 figs, gr. 8. …

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - In recent years, the technology of cryogenic comminution has been widely applied in the field of chemical engineering, food making, medicine production, and particularly in recycling of waste materials. Because of the increasing pollution of waste tires and the shortage of raw rubber resource, the recycling process for waste rubber products has become important and commercially viable. This technology has shown a great number of advantages such as causing no environmental pollution, requiring low energy consumption and producing high quality products. Hence, the normal crusher which was used to reclaim materials, such as waste tires, nylon, plastic and many polymer materials at atmospheric 12 temperature is being replaced by a cryogenic crusher. ¿ In the cryogenic crusher, the property of the milled material is usually very sensitive to temperature change. When a crusher is in operation, it will generate a great deal of heat that causes the material temperature increased. Once the temperature increases over the vitrification temperature, the material property will change and lose the brittle behavior causing the energy consumption to rise sharply. Consequently, the comminution process cannot be continued. Therefore, it is believed that the cryogenic crusher is the most critical component in the cryogenic comminution system. The research on the temperature increase and energy consumption in the cryogenic crusher is not only to reduce the energy consumption of the crasher, but also to reduce the energy consumption of the cryogenic system.…
