Abstract

The invention relates, inter alia, to the use of a coating agent containing chitin and/or chitosan for forming a skin (22, 23) on the surface of a body (14, 15, 16, 17a, 17b, 17c, 17d) that emits or transmits harmful substances or odorous substances, in order to absorb and/or collect the harmful or odorous substances and/or to prevent the emission of harmful or odorous substances from the body and/or to prevent transmission of the harmful or odorous substances through the body.
