SMOG-BUST­ING CON­CRETE, THE NETHER­LANDS

Hong Kong Tatler - - Features -

Dutch re­searchers have dis­cov­ered that con­crete, when in­fused with ti­ta­nium diox­ide, sucks ni­tro­gen ox­ides out of the air. When they paved a city street with the spe­cial con­crete, lev­els of the tox­ins were halved. They are now de­vis­ing ways to add ti­ta­nium diox­ide to common items, such as roof tiles, car ex­te­ri­ors and even cloth­ing, to re­duce air­borne pol­lu­tants.
