Exceedance days are defined as days with black smoke (BS) 24-hour average concentrations above 125 ?g/m 3 ; Total Suspended Particles (TSP) 24-hour average above 120 ?g/m 3 ; PM10 24-hour average above 50 ?g/m

Number and set of cities and measuring methods vary from year to year, and this may cause much of the inter-annual variation. The increase after 1996 is mainly due to the introduction of PM10 data into the statistics. Only for the most recent years monitoring data on fine particulates (PM10) are available to a significant extent, which are shown separately at the right-hand side of the diagram.
It will keep weeds away; protect the plants by keeping the soil cool; decrease evaporation and reduce soil compaction. Be creative and use materials like: pebbles, bark chippings, gravel, cocoa shells, decorative pine cones, marbles, broken crockery, grass clippings or leaf mould. But avoid mulching too close to the stems to avoid the plant rotting in winter.
