The present paper deals with the performance evaluation of Bambusa arundinacea with ten different fire retardants cum preservative compositions to offer protection against fire and bio-deterioration. The performance of treated bamboo against fire is tested by flame penetration test, inflammability test and rate of burning test as per Indian standards. Bambusa arundinacea treated with only five compositions passed all fire retardant tests. These compositions are Ammonium Sulphate + Ammonium Phosphate + Boric acid + Borax, Ammonium Sulphate + Ammonium Phosphate + CCB, Ammonium Sulphate + Ammonium Phosphate + ZnCI2 + CCB, Ammonium Sulphate + Ammonium Phosphate + ZnCl2 + Borax and Magnesium Pyrophosphate + Magnesium Phosphate + Borax + Boric acid.

Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzo-p-furans (PCDFs) are unintentionally formed during inefficient combustions and as a by-product. Due to their resistance to degradation and their toxic effect on health, PCDD/Fs are listed by the Stockholm Convention as persistent organic pollutants (POPs). Once released into the atmosphere, most of them are adsorbed to air particles and transported away from sources in atmosphere. India signed the Stockholm Convention India agreeing thereby to reduce and eliminate the use of POPs. The German agency for Technical Cooperation helped develop facilities for monitoring POPs at a national level in Delhi. This paper presents the data generated during a training assignment for Central Pollution Control Board officials at the German laboratory. Air borne particulate matter (HCDF (21%)>hexa-chlorodibenzofurans (13%)=OCDF (13%)> HCDF (12%) and other individual congeners contribute less than 5%. High chlorinated congeners contributed with more than 80% for ∑PCDD/Fs I-TEQ. Rough estimates of tolerable daily intake (TDI) shows low health risk of exposure to ∑PCDD/Fs with inhalation of 0.098 pg I-TEQ kg -1 day -1 for adult and 0.152 pg TEQ kg -1 day -1 for children, which is much lower than World Health Organization recommended TDI for dioxins.
