The aromatic hydrocarbons having a chain shape are generally referred to as aliphatic arenes, and common aliphatic aromatic hydrocarbons are toluene, ethylbenzene, styrene, and the like.
In October 2018, researchers reported low-temperature chemical pathways from simple organic compounds to complex polycyclic aromatic hydrocarbon(PAH) chemicals.
Whereas the other three piles were dead, dark and stinky, and the PAH's-- the aromatic hydrocarbons-- went from 10,000 parts per million to less than 200 in eight weeks.
With the help of big radiotelescopes, polycyclic aromatic hydrocarbons- large carbon-containing molecules- could be observed in abundance in interstellar space but why they exist and how they can form in interstellar conditions is still unclear.
Based on the EFSA estimates, the intake of aromatic hydrocarbons(MOAH) is at a level of around 20% of that observed for MOSH- in other words, between 0.006 and 0.06 mg per kilogram bodyweight and day.
Although early samples from water runoff into the Hudson and East Rivers showed some elevated levels of polychlorinated biphenyls(PCBs), dioxin, asbestos and metals, recent results find non-detectable levels of asbestos, and PCBs and polycyclic aromatic hydrocarbons(PAHs) and metals below the level of concern.”.
