Four selected plants (corn, groundnut, cow pea, and mungbean) were tested for their ability to germinate and grow in an acidic soil contaminated with phenanthrene or pyrene, two typical polycyclic aromatic hydrocarbons (PAHs). The growth of corn root was the least sensitive to, but its germination rate was the lowest in the presence of, contaminants. Among the legumes, the growth of groundnut root was better than others. Corn and groundnut were selected to further test their ability to tolerate a mixture of phenanthrene and pyrene in the acidic soil. The presence of both PAHs led to a greater decrease in the lengths of shoot and root of groundnut than phenanthrene or pyrene alone, but the lengths of shoot and root of corn were decreased to a similar extent as when phenanthrene or pyrene was present alone. The growth of corn root was also better than that of groundnut root when they were grown in oil-contaminated soil. Based on these results, we conclude that corn is the most suitable to be grown in PAH-contaminated acidic soil.

The World Health Organization has classified air pollution as a carcinogen, and polycyclic aromatic hydrocarbons (PAHs) are major components of air particulates of carcinogenic concern. Thus far, most studies focused on genotoxic high molecular weight PAHs; however, recent studies indicate potential carcinogenicity of the non-genotoxic lower molecular weight PAHs (LMW PAHs) that are found in indoor and outdoor air pollution as well as secondhand cigarette smoke. We hypothesize that LMW PAHs contribute to the promotion stage of cancer when combined with benzo[]pyrene (B[]P), a legacy PAH.

Polycyclic aromatic hydrocarbons (PAHs) are primarily generated through the incomplete combustion or pyrolysis of organic materials in various industrial processes. Foods may become contaminated with environmental PAHs found in air, soil, or water, or through industrial food processing methods such as smoking, roasting, drying, and grilling. The Ministry of Health and Welfare in Taiwan has established maximum levels for benzo[a]pyrene (BaP) and indicative values for BaP as well as PAH4 (the sum of benz[a]anthracene, chrysene, benzo[b]fluoranthene, and benzo[a]pyrene) in foods as operational guidelines.

Firefighters are exposed to a variety of hazardous substances during firefighting activities. Fire smoke contains polycyclic aromatic hydrocarbons (PAHs) some of which have been shown to cause cancer in humans. To assess dermal exposure of firefighters during real-life firefighting, a whole-body dosimetry method was applied to determine the PAH that settles on the skin despite firefighters wearing personal protective equipment (PPE).

We present a six-step cascade that converts 1,3-distyrylbenzenes (-stilbenes) into nonsymmetric pyrenes in 40-60% yields. This sequence merges photochemical steps, ,-alkene isomerization, a 6π photochemical electrocyclization (Mallory photocyclization); the new bay region cyclization, with two radical iodine-mediated aromatization steps; and an optional aryl migration. This work illustrates how the inherent challenges of engineering excited state reactivity can be addressed by logical design.
