射线，波和粒子从材料，技术过程或工业设备到环境的传输。在环境技术中，术语“排放”是指通常污染空气和/或水，放射性辐射，光束或热辐射以及噪声和振动的固体，液体和气体物质。这些排放可能对人类，动物和动物产生负面影响。排放导致排放。定义排放限值可实现排放控制。例如，带有内燃机的工业车辆产生噪声和废气形式的排放物。污染物浓度通过废气净化器降低。

          Transmission of rays, waves, and particles from materials, technical processes, or industrial equipment into the environment. In environmental technology the term "emission" designates solid, liquid, and gaseous substances that usually contaminate air and/or water, the transmission of radioactive radiation, light beams or heat radiation as well as noise and vibrations. These emission can have negative effects on humans, animals, and plats. Emissions lead to immission. Defining emission limit values results in immission control. For example, industrial trucks with combustion engines produce emissions in form of noise and exhaust gas. The pollutant concentration is reduced by means of exhaust gas purifiers.
