Environmental chemistry is a new field of study in many chemistry departments and only three published summaries of environmental laboratory experiments are available (1–3). While these laboratory manuals contain excellent experiments for the training of students in environmental monitoring, relatively few standardized procedures have been published for broader issues such as the measuring of f...

The term “pollutant emergent” refers to any type of contaminant originated from previously undetected or products that were not problematized in health and environment [1]. In this group of pollutants has a product for veterinary use, personal care products, and pesticides. The pharmaceuticals in the aquatic environment should be highlighted by reaching the environment through discharges or exc...

To offset the detrimental effects of urbanization on groundwater recharge, stormwater managers are focusing on infiltrating much of the runoff from a site that was generated because of development. For this to be effective, tools are required to predict the potential for contamination resulting from this infiltration for many site conditions, because infiltration should be stressed in areas whe...

We collected urban soil samples impacted by polycyclic aromatic hydrocarbons (PAHs) from a sorbent-based remediation field trial to address concerns about unwanted side-effects of 2% powdered (PAC) or granular (GAC) activated carbon amendment on soil microbiology and pollutant biodegradation. After three years, total microbial cell counts and respiration rates were highest in the GAC amended so...

The source profile for soil in Hong Kong is important both for determination of the main air pollutant source in Hong Kong and for assessment of the impact of Asian dust storms on Hong Kong. Soil associated with different rock types have been sampled, and the concentrations of 19 chemical elements, Na, Al, Si, Ti, V, Cr, Mn, Fe, Co, K, Ca, Ni, Cu, Zn, Pb, Rb, Sr, Y and Zr, have been determined ...

Peroxidase enzymes can enhance the rate and extent of contaminant binding to soil organic matter and immobilize the contaminant within the soil matrix, and thus prevent its transport into the subsurface. This study focused on evaluating the binding of phenol, dichlorophenol, and naphthol, individually and as mixtures, on two sandy loams belonging to the Haynie series. U-ring-14 C-labeled target...

The effects of urbanization on soil structure can be extensive. Infiltration of rain water through soils can be greatly reduced, plus the benefits of infiltration and biofiltration devices can be severely jeopardized. Our research group (along with others), have been studying disturbed urban soils for several decades, both in the laboratory and in the field. The effects of compaction on infiltr...

The effects on the environment of pollution, particularly that caused by various industrial activities, have been responsible for the accelerated fluxes of organic and inorganic matter in the ecosphere. Xenobiotics such as phenol, phenolic compounds, polycyclic aromatic hydrocarbons (PAHs), and heavy metals, even at low concentrations, can be toxic to humans and other forms of life. Many of the...

Most widely used nonpoint source models associate pollutant loads almost exclusively with land use via pollutant export coefficients and some kind of runoff coefficient. Not surprisingly, the range of management options suggested by such models’ simulations are largely linked to changes in land use. This problem is addressed by developing models of dissolved phosphorus DP mobility for specific ...

environmental pollution by various pollutants is one of the most important problems of this century. at least 20 elements, including chromium have been classified in toxic metals group, that half of them are released in the environment in excessive amounts of standards. chromium is a toxic pollutant that is widely spread in the environment and exists in cement and concrete. the aim of this stud...
