Popis:	In this paper, the effect of humidity and dust trapped in avalanche region on leakage current of bulk micro-MEGAS detector is studied. Pyralux PC1025 layers of DuPont are introduced in bulk technique and micro-MEGAS detector with pillars of 300{\mu}m in diameter is fabricated. Leakage current is tested in air with different humidity. Silicon carbide powder and PMMA (polymethyl methacrylate) powder are added as dust to avalanche region. Leakage current with and without powder is tested in air and results are depicted in the same figure. Test results indicate that leakage current increases with both storage humidity and test humidity, and also increases when powder is introduced in avalanche region. Comment: 4 pages, 5 figures
