Article Abstract
In previous studies, statistical method using distribution of detergent power and that of resistance of soil against washing was applied to analyze detergency of oily soil and solid particle soil. In this paper, this method was applied to an analysis of detergency of mixed soil. Artificially soiled cloth prepared by aqueous dispersion method was used as a mixed soil sample. Four-time consecutive washing tests were conducted under the same washing condition in Terg-O-Tometer using two kinds of detergent solution and distilled water. Change of removal efficiencies due to repetitive washing was used to determine the two distributions. Result shows that detergent power can be expressed as cumulative distribution function. In washing simulation using the cumulative distribution functions, the predicted removal efficiencies corresponded with experimental values. Moreover, the effect of soil aging on distribution of soil resistance against washing was found to move the distribution curve toward high resistance. These results show that the method using two statistical distributions can be applied to the detergency of mixed soil.

Soil drivers of fungal, bacterial and plant diversity in contaminated Southern Californian sites: Implications for dryland bioremediation.

University of California Riverside, Department of Environmental Sciences and Environmental Toxicology Graduate Program, Riverside, CA, USA.
This exploratory study surveyed seven contaminated brownfields and Superfund sites in Southern California to identify locally adapted species tolerant of mixed organic and metal contamination under arid and semi-arid conditions. Five novel native plants, including Brickellia californica, Baccharis salicifolia, Baccharis sarothroides, Eriogonum fasciculatum, and Heterotheca grandiflora were identified as hyperaccumulators of copper (Cu), alongside a non-native species from the Asteraceae family, Helminthotheca echioides. Additional metal-accumulating plants (including native plants) for lead (Pb), chromium (Cr), arsenic (As), and nickel (Ni) were identified, and warrant further evaluation for their phytoremediation potential.

This study presents the first attempt on plant biomonitoring of the polycyclic aromatic hydrocarbons (PAHs) pollution in East Kolkata Wetland (EKW), a Ramsar site in India, using Alternanthera ficoidea (L.). A polluted site, Captain Bheri (CB) and a control area, Kansabati River Basin (KRB) are chosen to compare the severity of the PAHs pollution of the wetland by examining wetland sediment and wetland plant parts (leaf, root, stem, rhizobium).

1,2,3-Trichloropropane (1,2,3-TCP) is a suspected human carcinogen and a persistent emerging contaminant in groundwater and drinking water. 1,2,3-TCP was historically used as a solvent for cleaning and maintenance, paint and varnish removal, and degreasing, but its sources also include chemical manufacturing processes and application of soil fumigants. The California Department of Public Health (CDPH) has established a state maximum contaminant level (MCL) of 0.

In recent years, the use of waste materials for soil stabilization has gained attention due to their environmental and economic advantages. Kevlar, a synthetic, high-strength fiber commonly used in telecommunications, becomes a significant source of industrial waste at the end of its service life. In this study, the potential utilization of waste Kevlar material for improving clay soils against freeze-thaw effects was investigated using computed tomography (CT) and scanning electron microscopy (SEM) imaging techniques.

Phosphogypsum is an acidic solid waste mainly composed of CaSO₄-2H₂O by-products of the wet process phosphoric acid industry, which has the characteristics of high impurity content, poor stability of stockpiling, but can be utilized in a resourceful way. Phosphogypsum waste utilization can reduce environmental pollution, save resources and create economic value. In order to investigate the fatigue characteristics and the mechanism of dynamic strength change of cement-phosphogypsum-red clay under wet and dry cycles, the cumulative deformation characteristics and the rule of change of critical dynamic stress of the mixed materials were investigated by dynamic triaxial fatigue test, SEM and XRD test, and the mechanism of dynamic strength change was analyzed according to the microstructure and the chemical mineral composition of the mixed materials.
