The title compound, C(19)H(11)NO, is stabilized by one intra-molecular C-H⋯O hydrogen bond. The compound can be synthesized in good yield (49%), by transformation of functional groups [starting with 5-(fluoren-9-ylidenemeth-yl)furan-2-carbaldehyde]. The flourene and furan ring systems are nearly coplanar, with a dihedral angle of 6.36 (7)°.
Flourene and phenanthrene are organic compounds with high hydrophobicity and toxicity. Being recalcitrant in nature they are accumulating in the environment at an alarming concentration, posing serious threat to living beings. Thus in the present study, microorganisms were screened for their ability to degrade these contaminants at high concentrations in least period of time. Two out of fifteen...

In the oil-rich Niger Delta, hydrocarbon pollution and oil spillages, gas flaring and sundry anthropogenic activities constitute sources of polycyclic aromatic hydrocarbons (PAHs), with food contamination playing a major role in human exposure. In this study we assessed PAH levels in wild and cultivated edible mushroom species consumed by the general population from the oil producing Niger Delt...
Oil spills are one of the environmental pollutions that commonly occur along coastal areas. Tar-balls products come from oil spill pollution. In this study, tar-ball pollution was monitored at 10 points coastline Marintaman Beach in Sipitang, Sabah, Malaysia. This research determined physical characteristics, composition, and concentration Polycyclic Aromatic Hydrocarbons (PAHs) tar-balls. The ...
Aim: The aim of this study is to generate and investigate oral bioaccessibility based on the health risk polycyclic aromatic hydrocarbon (PAHs) in fly ash from waste tyres petroleum products Rivers State, Nigeria.
 Study Design: Crude oil, crude oil asphalt, artisanal diesel, refined engine samples were collected incinerated. different analyzed with GC-MS.
 Place Duration Study: State...
It is known that many soil fungí synthesize brown, large aromatic polymers (fungal melanins), chemically related to soil humic acids (Martin and Haider, 1971; Schnitzer and Neyroud, 1975). Since the chemical constituents (or at least, their degradation products) and the physicochemical properties of fungal melanins are comparable to those of humic acids, it is possible that fungal metabolism ma...
