In 1998, sampling of airborne particles equal or less than 10 m (PM10), were made every four days (in average), during 24 h, in the southwest of the Metropolitan Zone of the Valley of Mexico. The correlation between PM10 and extracted organic matter (EOM) was significant (r=0.81, p<0.0001), suggesting that...
The influence of type of reactor (CSTR, completely stirred tank reactor and airlift) and type of influent (lithoautotrophic medium, lithoautotrophic medium plus acetate and lithoautotrophic medium plus complex wastewater) on exopolymeric substances produced by a nitrifying sludge (proteins, carbohydrates and lipids) as well as its relationship with sludge settleability was...
When contaminants such as hydrocarbons have contact with soil, one possible environmental fate is sequestration, which consists of “trapping” the hydrocarbon within the soil matrix. Soil organic matter (SOM) is a key soil component which controls the fate of hydrocarbons in soil. However, there are no standardized methods to accurately...
