n Clean Air Journal = Tydskrif vir Skoon Lug - President's message




For the past two years the NACA Journal has been silent. This was due to the attempt to provide our members with the NACA Magazine, a combination of the traditional journal content and more contemporary air quality matters. The financial outset proved not viable and I am pleased to welcome back our trusted Journal. This publication covers feedback from the 2009 Annual Conference and the 2009 winning papers.
