The metal concentrations and isotopic compositions (13C, 207/206Pb) of urban dust, topsoil, PM10 samples were analyzed in a residential area near Donghae port, Korea, which is surrounded by various types industrial factories raw material stockpiled on empty land, to determine the contributions main pollution sources (i.e., Mn ore, Zn cement, coal, coke, topsoil). dust port approximately 85~112 ...

Soil organic carbon (SOC) fractions, along with soil properties, are greatly affected by forest management. In this study, three thinning treatments: control (conventional management mode), moderate thinning intensity and heavy thinning intensity, were applied in Chinese fir (Cunninghamia lanceolata) plantations in eastern China. The dissolved organic carbon (DOC), soil light fraction organic c...

A media consisting of isatin-Schiff bases and its inclusion complexes with β-cyclodextrine was developed to maximize the production of antibiotics Hexaene H-85 and azalomycine B by Streptomyces hygroscopicus CH-7. The media with β-cyclodextrine inclusion complex of isatin-3-thiosemicarbazone resulted in the maximum antibiotics concentration of 493 μg/cm for Hexaene H-85 and 191 μg/cm for azalom...

The spatial distribution of organic substrates and microscale soil heterogeneity significantly influence matter (OM) persistence as constraints on OM accessibility to microorganisms. However, it is unclear how changes in driven by factors such depth affect the relative importance substrate persistence. This work evaluated decomposition 13C 15N labeled water-extractable inputs over 50 days eithe...

The Peel–Harvey estuarine system in Western Australia's south-west is affected by poor water quality, algal blooms, and fish kills. Phosphorus (P) discharge from agricultural activities the main source of quality. catchment’s soils are naturally infertile, but P application has increased fertility. This paper draws on undertakes a meta-analysis 20 200 surface (0–10 cm) profile (to 100 cm depth)...

The efficacy of a photostable formulation of methoprene and two photostable juvenoids, fenoxycarb and pyriproxyfen, and their residual activity in inhibiting the emergence of adult cat fleas, Ctenocephalides felis (Bouché), was studied in topsoil. Nursery pots composed of clay, peat, and plastic, and wooden flats were used to hold soil samples. Treated soil samples were exposed to sunlight duri...

The magnetic susceptibility (MS) in soils is a fast and non-destructive technique that can be used to infer the concentration of magnetic minerals. The objective of this study was to analyze MS on topsoil and bulk core samples of cultivated Calcisols. Magnetic susceptibility was measured at two different frequencies to assess the variation of magnetic susceptibility when the frequency of the ap...

Tianjin urban/industrial complex is highly polluted by some persistent organic pollutants. In this study, the levels of 16 priority polycyclic aromatic hydrocarbons (PAHs) were tested in sediment, water, and suspended particulate matter (SPM) samples in 10 rivers in Tianjin. The total concentration of 16 PAHs varied from 0.787 to 1943 microg/g dry weight in sediment, from 45.81 to 1272 ng/L in ...

Establishing vegetation on roadsides following construction can be challenging, especially for relatively slow growing native species. Topsoil is generally removed during construction, and the surface soil following construction ("cut-slope soils") is often compacted and low in nutrients, providing poor growing conditions for vegetation. Nebraska Department of Transportation (NDOT) protocols ha...
