Persistent Organic Pollutants (POPs) in water can reach levels below ppt (ng L−1), representing a challenge for risk assessment using long-term exposure. Therefore, sampling devices to monitor trace of organic compounds are suitable due their sensitivity and low detection limits. In this work, the field calibration monitoring POPs, such as Polycyclic Aromatic Hydrocarbons (PAHs) pesticides, dri...

The potential of five low-cost and globally available sorbents, including three raw waste products – tire crumb rubber (WTCR), coconut coir fiber (CCF) blast furnace slag (BFS) two modified materials biochar (BC) iron coated (FeBC) were evaluated for removing a mixture polycyclic aromatic hydrocarbons (PAHs): pyrene (PYR), phenanthrene (PHE), acenaphthylene (ACY) naphthalene (NAP) from simulate...

Models capturing the growth of polycyclic aromatic compounds (PACs) and nanoparticles in combustion have always faced a large degree uncertainty due to paucity detailed direct experimental validation. In particular, data on molecular structures, chemical composition, size, cross-linking, aliphatic chains is still very limited. past few years, we developed an atomistic code, SNapS2, that models ...

ABSTRACT. The aim of this investigation was to assess the presence 16 PAHs (naphthalene, acenaphthylene, acenaphthene, fluorene, anthracene, phenanthrene fluoranthene, benz[a]anthracene, pyrene, chrysene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[a]pyrene, dibenzo[a,h]anthracene, benzo[ghi]perylene, and indeno[1,2,3-cd]pyrene with symbols Nap, Ace, Ane, Flu, Ant, Phe, Flt, BaA, Pyr, Chr...

Emissions of PAH, nitro-PAHs, and oxy-PAHs from a diesel engine fueled with diesel-biodiesel-ethanol blends need to be controlled reduced, as they are unregulated emissions harmful the environment human health. The objective this work was investigate effect ethanol concentration on when diesel–biodiesel–ethanol blends. Ethanol added biodiesel–diesel Diesel B7 two ternary blends, B7E3 B7E10, 3% ...

Concentration levels of 16 polycyclic aromatic hydrocarbons (PAHs) consisting of naphthalene, acenaphthylene, acenaphthene, fluorine, phenantherene, anthracene, fluor?anthene, pyrene, benzo(a)anthracene, chrysene, benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(a)p?yrene, dibenzo(a,h)ant?hracene, indeno(1,2,3-cd) pyrene and benzo(g,h,i)perylene were measured in water and sediment samples col...
