Abstract

Vapors of chemicals or minerals in solution, and/or volatile liquids, emanating from a land surface (such as a sanitary landfill) are collected. A first generally cylindrical container encloses the volume of air above an area of land surface, and includes a top surface having an inverted cone shape with a downwardmost point formed by the cone apex. A second generally cylindrical container interfits with the top, inverted cone, first container. The second container is adapted to contain ice, or a like cooling solid or liquid. The second and first containers are of good heat conducting material so that the second container cools the top of the first container. Thus vapors emanating from the land surface condense on the top of the first container, roll down the interior surface thereof to the cone apex, and the condensate drips into a collecting vessel disposed within the first container, below the cone apex. A cover of heat insulating material is placed on top of the first container, and completely surrounds the second container to insulate it from the environment. The insulating cover, and first and second containers are preferably of opaque material, and are dimensioned and shaped so that they nest for ease of transportation. The collected condensate is analyzed to determine the mineral and chemical composition thereof.
