In the present investigation, an attempt for the reduction of six hazardous air Pollutants (HAPs) from diesel exhaust by different blends of diesel and biodiesel has been made. The synthesis of biodiesel has been done from Jetrofa, Linseed Castor and Karanja oils which are commonly used in the Indian market. Blending of diesel with biodiesel was done in different ratios (20 to 40 %) for the estimation of carcinogenic HAPs from the exhaust of a Honda engine (EBK 2010AC Model). The order of HAPs emission from engine exhaust by using diverse blends were Diesel>Jatropha-diesel>Linseed-diesel>Castor-diesel> Karanja-diesel. The maximum reduction of HAPs was established in the following ratio 40% (Biodiesel):60% (Diesel). B(a)P and Chrysene were the two individual aromatic hydrocarbons (AHCs) found in higher concentration in almost all blending fuels, ranging between 50 ng/µl to 101.1 ng/µl. The emission of almost all AHCs reduces by Blending of Diesel with Biodiesel. This was the first comprehensive information which showed the reduction of carcinogenic pollutants from diesel exhaust.

The efficiency of the study of polycyclic aromatic hydrocarbons (PAHs) as markers of many environmental and hydrological processes is disclosed. On the example of the interaction between sea and river water the flows of substances and problems of their detection in media, as well as the laws of fractionation during phase transitions at geochemical barriers (GCB) are presented. The authors have collected an extensive database for almost all types of natural environments. Own research was conducted at specialized water testing sites (springs, a mud volcano, brine of a lake, the Northern Dvina River, water of Black and White Seas, water bodies of the Moscow Region and Albena region (Bulgaria), etc. This allowed substantiating the optimal markers and creating effective methods for identifying a complex of hydrological processes.
