Estimation of Polycyclic aromatic hydrocarbons is done in the current study because of its carcinogenicity and mutagenic property. Biodiesel has received the maximum attention in the recent years but the main advantage of using neat biodiesel/Biodiesel blended with diesel as a fuel are its renew ability, better quality exhaust gas emission, easy availability and its biodegradability. Blending low levels of biodiesel with conventional diesel fuel is an important option for displacing imported petroleum consumption and reducing harmful emissions. Low blends of biodiesel can be defined as blends containing 5% and below. Even low blends of biodiesel provide a greater lubricity than standard diesel fuel alone. These blends usually consist of 2% biodiesel mixed with 98% diesel (B2). Any blend of up to 5% biodiesel is considered an additive volume (B5 is 5% biodiesel/95% diesel). Some of the obvious benefits to biodiesel blending are the increased fuel lubricity and reduction in emissions. Biodiesel can be blended with petroleum diesel at any percentage however only B20 (20% biodiesel, 80% petroleum) and higher qualify for fuel credit. Biodiesel can also be used in its pure form (B100), but may require certain engine modifications to avoid maintenance and performance problems. In present investigation an attempt has been made to synthesis biodiesel from Castor, blending of diesel with biodiesel in different ratio and estimation of Polycyclic Aromatic Hydrocarbons (16 according to EPA). The order of PAHs generation by using different kind of fuels were Diesel > Castor (25:75) > Castor (35:65)> Castor (45:55). Ace Naphthalene was the individual PAH found in higher concentration in almost fuels and ranging between 5.2 ng/
