Volatile organic compounds (VOCs) are main type of indoor pollutants which are found in many workstation materials.
At the material-material interface (interface between layers), for the same VOC, concentrations in the materials are proportional to the partition coefficients, while the gas phase concentrations are the same at the interface for both materials.
Mass balance was applied for VOCs in materials, at the interfaces and in the chamber[10,11].
The source material is homogenous, and the initial concentration is uniform in the materials. 5.
P.Zhang, An improved mass transfer based model for analyzing VOC emissions from building materials.

In addition, each of the methods is usually preceded by the stage of mechanical preparation of the raw materials, where the techno-genic waste is crushed.
The modern technologies and equipment make it possible to recover useful metals and minerals partially or fully from the technogenic raw materials.
Materials and Methods The dump nickel slags from the Rezhsky, Ufaleysky and South Ural metallurgical plants were used in present study.

High temperature oil water will cause the oil drops splashing, water mist spray fire if there is high or burning oil drops from splashing out, can cause personal injury, or ignition of combustible materials nearby causes the fire spread,as a result the nozzle working pressure is too high, the droplet diameter is larger and other factors Through the experiment in the process of observation, we found the selection coefficient is1.3 when the applicator has splash phenomenon, the pan around the ground floor there is a trace of oil splash.
