“…The mean concentration of Σ 16 PAHs in soils of the CentralHimalayas region was greater than those in soils of Changbai Mountain and mountains of Western Canada, but less than those in soils of European mountain areas and subtropical Atlantic areas (Ribes et al, 2003a;Choi et al, 2009;Quiroz et al, 2010;Zhao et al, 2015) ( Table S1). Unlike that in other studies conducted in Nepal, the mean concentration of Σ 16 PAHs in soils of Nepal was greater than that in soils of Sagarmatha National Park, but less than that in soils of Kathmandu (Aichner et al, 2007;Guzzella et al, 2011), as well as Agra, Delhi, Kurukshetra, and other cities located in the north of India ( Masih and Taneja, 2006;Agarwal et al, 2009;Kumar et al, 2013). These results indicated that sources of PAHs might be present in the vicinity of the area.…”

“…In this study, the mean concentration of Σ 16 PAHs in soils of the TPC was approximately 3-fold greater than region background concentrations for the Qinghai-Tibetan Plateau (Tao et al, 2011;Wang et al, 2013), but similar to those in the southeastern TPC, which is considered to receive PAH input via the Indian monsoon (271 ng/g dm) (Yang et al, 2013). The pattern of concentrations of Σ 16 PAHs in soils from the study area was significantly different from that in other areas affected by human activities, such as the traffic-affected and coal-related area of Dalian and densely populated area in Agra, where 4-ring and HMW-PAHs were dominant in soils (Masih and Taneja, 2006). LMW-PAHs were also dominant in soils from mountain areas of Canada, southeast areas of the TPC, and the Qinghai-Tibetan plateau (Choi et al, 2009;Wang et al, 2013;Yang et al, 2013).…”

“…The contributions of different PAHs to the TEQ decreased in the order: BaP (62.5%) N DBA (19.2%) N BbF (6.2%) N BaA (4.3%) N InP (3.1%) N BkF (1.6%). The TEQ concentrations were significantly lower than those in soils at a semi-dried area of India (Masih and Taneja, 2006), and also lower than those of agricultural area in Delhi and Shanghai (Agarwal et al, 2009;Jiang et al, 2011a); but higher than those in the soil from unpolluted areas of Spain (Nadal et al, 2004).…”

Thirty-one topsoil samples were collected from the area of the Yanshan petrochemical industries to comprehensively determine the spatial distribution, the possible sources and the potential risks of legacy Persistent Organic Pollutants (POPs) in a typical petrochemical industrial area. The total concentration of 16 PAHs, predominantly originated from the local emission from fuel combustion, ranged from 35.29 to 6120.22 ng/g with a mean value of 906.11 ng/g. Organochlorine Pesticides (OCPs) originated mainly from the recent inputs and their total concentrations varied from 4.13 to 7215.24 ng/g with a mean of 336.13 ng/g. Polychlorinated Biphenyls (PCBs) were associated with the usage of commercial products and the total concentrations of 125 congeners ranged from 2.21 to 4008.47 ng/g with a mean of 486.12 ng/g. Residential Total Lifetime Carcinogenic Risk (TLCR) value, higher than the target excess individual lifetime risk (1 × 10 −6), was calculated to be of 22.6% for PAHs, 16.1% for OCPs and 6. 5% for PCBs respectively. Occupational TLCR, higher than the target excess individual lifetime risk was of 9.7% for PAHs, 6.5% for OCPs and 0% for PCBs respectively. In all sampling sites, non-carcinogenic risks expressed as Total Hazard Quotient (THQ) for PAHs, OCPs and PCBs were always below 1. As a consequence, the carcinogenic and non-carcinogenic risks due to exposure to POPs in soil were very low even in such a typical petrochemical industrial area. In the study, the management and the risk assessment of POPs in a petrochemical industrial area close to a metropolis, were evaluated comprehensively.

“…Motor vehicles are one of the utmost common modes of transportation in numerous countries around the world (Satyarthi et al, 2009;Masih and Taneja, 2006). Some south Asian countries also falls into the same category where we have over one million buses which account for 17% of all the motor vehicles.…”

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.
