In this study, phenol was adsorbed by commercial coconut shell charcoal (CSC), which is inexpensive, commercially available, non-toxic, and environmentally friendly. The measurements, namely the density functional theory (DFT) calculation, the energy-dispersive X-ray spectroscopy (EDS), and Fourier-transform infrared spectroscopy (FTIR), were conducted to characterize the features of the CSC.

The Camellia tamdaoensis Hakoda et Ninh contains many useful phenolic compounds for human health, among them, flavonoids showed many biological activities such as antibacterial, antiinflammatory. In this study, we used the recovery extract method to collect concentrated solutions with high flavonoid content from golden tea leaves, in which ethanol served as solvents at the temperature of 70°C for 1 hour.

In this study, nine ferulic and caffeic acid-based 1,2,4 and 1,3,4 oxadiazole molecular hybrids were synthesized and their cytotoxic activity was evaluated mainly against Glioblastoma (GBM) cell lines. Compounds 1 and 5 exhibited the highest inhibitory activity against three different GBM cell lines (LN229, T98G, and U87), without toxicity to healthy human mesenchymal stem cells (hMSC). In addition, their cytotoxicity was also evaluated against three additional cancer cell lines and more inhibitory results were found than GBM cell lines.

Erodium genus contains several medicinal traditionally used and pharmacologically explored. However, Erodium guttatum has not been well valorized. Therefore, the aim of the present study was to evaluate the antibacterial and antioxidant activities of E. guttatum extracts in addition to their toxicity. To achieve the objectives of this study, methanol and aqueous extracts of E. guttatum were prepared.

Toxicity of metal cations and phenolic compounds to the bioluminescent fungus Neonothopanus gardneri
The current bioluminescent assay, which uses a fungus of the Omphalotus lineage, fills a gap covering all the representative species of bioluminescent fungi. Among the compounds tested here, Cd(II) showed the highest toxicity, followed by 4-nitrophenol, phenol and Cu(II).

Vegetables and fruits are vital constituents of human diet, as it provides necessary minerals and nutrients to human body to carry out biological reactions and provide protection against various diseases and injuries. Solanum lycopersicum (tomato) is consider as cash crop in Asian countries and are fine source of vitamin C, potassium, folate, vitamin K, and other bioactive compounds including, phenolics, flavonoids, carotenoids, and alkaloids. Similar to other crops, tomato quality and yield is also affected by pests. Globally, approximately 37.8% of tomato yield is spoiled due to pests.

Chemical inducers facilitate broad-spectrum of induced resistance against plant pathogens and thus reduced the toxicity of the chemicals used in excess by the farmers for the management of plant diseases. Banana soft rot incited by Pectobacterium carotovorum subsp. Carotovorum (Pcc) cause huge economical loss to the farming if infected at an early stage. In the present study, chemical inducers viz., salicylic acid, potassium silicate, potassium sulphate, fosetyl aluminium, humic acid @ 1000 ppm and COC 3g/lit + streptocycline 300ppm (check) were tested against Pccunder glass house conditions.

Phenol is a toxic hydrocarbon for nervous system, kidneys, liver, muscles and immune system. It is also mutagenic and possibly carcinogenic. Phenol containing- pollutants are dangerous and spread worldwide in the industrial effluents.The present study aimed to isolate a potent microorganism able to degrade phenol, as well as to evaluate the nutritional and environmental conditions that lead to its maximum degradation. A yeast isolated from petroleum-contaminated soil on MSM supplemented with phenol as sole carbon source, was identified by 28S rDNA sequencing.

Vanillin, a type of phenolic released during the pre-treatment of lignocellulosic materials, is toxic to microorganisms and therefore its presence inhibits the fermentation. The vanillin can be reduced to vanillyl alcohol, which is much less toxic, by the ethanol producer Saccharomyces cerevisiae.

Phenol and its components are extremely toxic and can easily be isolated from different industrial sewage such as oil refinery, petrochemical industry and mines, especially chemical factories causing pollution in water bodies. Rivers and oceans are contaminated on a large scale with these toxic compounds. In the past, physicochemical method was used for the elimination of phenol and its compounds, but today, bioremediation is preferable.

In this work, the Golden Flower Tea extract (GFTE) which is extracted from the Golden Flower Tea was used as a model drug. It is one of the precious medicinal herbs because it contains over 400 chemical compositions (saponin, phenolic compounds, amino acids, folic acid, proteins, vitamins B1, B2, C, E, fatty acids, and many natural nutrients) and non-toxic.

There is lack of information regarding; the toxicological and pathological consequences of phenol stressed Clarias gariepinus; as well as; the susceptibility of the stressed fish to disease occurrence. Static renewal bioassay was experimentally conducted to evaluate the toxic effects of phenol on the African catfish C. gariepinus. Ninety-six-hour acute toxicity tests revealed that the median lethal concentration of phenol (LC50) is 35 mg/L by immersion.

despite this disparity in the quantity of environmental releases, dioxins and furans have dominated the debate over regulatory controls of the effluents from pulp and paper plants that use chlorine bleaching because chlorinated phenols and volatile organochlorines are estimated to be very much less toxic.

Human UDP-glucuronosyltransferase 1A (UGT1A) isoforms are endoplas-mic reticulum (ER)-resident type I membrane proteins responsible for the detoxification of a broad range of toxic phenolic compounds. These pro-teins contain a C-terminal stop transfer sequence with a transmembrane domain (TMD), which anchors the protein into the membrane, followed by a short cytosolic tail (CT).

However, cellular uptake of aglycones has been suggested to occur in their native form by passive diffusion. Absorbed polyphenols can directly undergo phase II metabolism as phenolic structures are generally unfavorable substrates to the cytochrome P450s (phase I metabolism). At nutritional doses, almost all polyphenols are conjugated to form O- glucuronides, sulfate esters and O-methyl ethers, by glucuronidation, sulfation and methylation, in the gut mucosa and later in the liver or kidney.

Carmago et al. (1992) found that the rivers nearer industrial discharge point have adverse impact to the environment as well as to macrobenthic communities. Toxic contaminants from surface runoff, sewage discharges and industrial discharge have caused negative impacts towards the freshwater macrobenthic communities. The presence of substance chemical such as ammonia, chlorine, cyanide, metals, PCBs, pesticides and phenols would caused a decline pattern on the number of species and changes in the species composition.
