Amounts released from industry types not covered byPRTR (e.g. construction)  2. Amounts released from small enterprises (20 or lessemployees per enterprise)  3. Amounts released when the amounts used or producedare less than 1 t (or 0.5 t) per facility  4. Amounts released from mobile sources (e.g. vehicles)  5. Other amounts released (e.g. households)
