In the petroleum refining and petrochemical industries, the initialism BTX refers to mixtures of benzene, toluene, and the three xylene isomers, all of which are aromatic hydrocarbons. The xylene isomers are distinguished by the designations ortho – (or o –), meta – (or m –), and para – (or p –) as indicated in the adjacent diagram.
Hash oil or cannabis oil is an oleoresin obtained by the extraction of cannabis or hashish. [1] It is a cannabis concentrate containing many of its resins and terpenes – in particular, tetrahydrocannabinol (THC), cannabidiol (CBD), and other cannabinoids. Hash oil is usually consumed by smoking, vaporizing or eating. [2]
Benzene in soft drinks has to be seen in the context of other environmental exposure. Taking the worst example found to date of a soft drink containing 87.9 ppb benzene, [5] someone drinking a 350 ml (12 oz) can would ingest 31 μg (micrograms) of benzene, almost equivalent to the benzene inhaled by a motorist refilling a fuel tank for three ...
A case of environmental contamination is defined as 'serious' if >25 m 3 soil or >100 m 3 groundwater is contaminated above the intervention value. The values presented below are from Annex 1, Table 1, "Groundwater target values and soil and groundwater intervention values".
These include BTEX compounds (benzene, toluene, ethylbenzene, and xylene found in gasoline), and solvents including trichloroethylene and tetrachloroethylene. Ammonia can also be stripped from wastewaters and liquid digestates (often requiring pH adjustment prior to stripping).
Cannabis irradiation is a process used in the cannabis industry to remove or inactivate microbial contaminants (mold, fungus, etc.) from cannabis meant for human consumption, using various forms of radiation.
In particular, benzene, toluene, ethyl benzene and the xylenes are of great environmental interest due to their availability to organisms. This availability, also influenced by volatility and reactivity , impacts on biodegradation and bioremediation in water and soil environments, with even dissolved components within pore water considered ...
Many compounds found in oil are highly toxic and can cause cancer (carcinogenic) as well as other diseases. [23] Studies in Taiwan link proximity to oil refineries to premature births. [26] Crude oil and petroleum distillates cause birth defects. [27] Benzene is present in both crude oil and gasoline and is known to cause leukaemia in humans. [28]
