Tph speciation
SpletTotal petroleum hydrocarbon (TPH) is a mixture of various oil substances composed of alkane, alkene, cycloalkane, and aromatic hydrocarbons (benzene, toluene, ethylbenzene, xylene, etc.). In this study, we investigated 92 groundwater wells around 36 gas stations to evaluate distribution characteristics of petroleum hydrocarbons. Splet23. nov. 2024 · There are total of 4 types of speciation i.e. allopatric, parapatric, peripatric and sympatric speciation. However, artificial speciation is also included sometimes. Allopatric speciation occurs when speciation via geographical separation takes place whereas sympatric speciation occurs when speciation occurs without geographic isolation.
