Composite Microbial Preparations: Soil and Groundwater Environmental Standards in Asian Countries
Complex bioformulations for the degradation of PAHs, which contain over 100 chemical substances.
The number of environmental regulatory substances for soil and groundwater in Japan is small, and among them, the regulation of substances derived from petroleum products is extremely limited. Not only in Asian countries but also in other countries overseas, substances derived from petroleum products are regulated, and TPH (Total Petroleum Hydrocarbons) is naturally included, along with standards set for BTEX (Benzene, Toluene, Ethylbenzene, Xylene) and PAHs (Polycyclic Aromatic Hydrocarbons). However, in Japan, although oil contamination countermeasure guidelines have been established, they primarily address issues related to oil odor and oil film, and there are no established standards for TPH or PAHs. (Benzene is regulated under the Soil Contamination Countermeasures Act, but Toluene, Ethylbenzene, and Xylene are not included.) On our website, we introduce examples of PAHs decomposition tests using the composite microbial agent 'Oppenheimer FormulaTM'. [Test Examples] ■ Decomposition test of PAHs contained in diesel oil ■ PAHs decomposition tests using various microbial agents *For more details, please feel free to contact us.

basic information
**About PAHs** ■ PAHs (Polycyclic Aromatic Hydrocarbons) - A general term for hydrocarbons formed by the condensation of aromatic rings that do not contain heteroatoms or substituents. - Also referred to as condensed ring hydrocarbons, with over 100 chemical substances present. ■ Properties - Lipophilic, poorly soluble in water, easily adsorbed by soil, and non-volatile. - Several types of PAHs are carcinogenic, mutagenic, and teratogenic. ■ Causes of Contamination - Found in deposits of oil, coal, and tar. - By-products of the combustion of fossil fuels and biomass fuels. *For more details, please feel free to contact us.*
