Distribution behaviour of trace and toxic metals in soil and sediments along the Thane Creek near Mumbai, India
The long biological half lives, non-bio-degradable nature and accumulative properties of trace and toxic heavy metals in aquatic environment has attracted great attention of environmental scientists and ecologist in recent years. Therefore, in the present investigation, we have selected Kalwa Bridge and Balkum sites along the Thane Creek to investigate pollution load due to trace and toxic heavy ...

Contaminated Soil Sampling Method
What is Contaminated Soil Sampling? Use of a proper contaminated soil sampling method is vital to obtain a representative sample of soil waste. A representative sample of soil waste is necessary to accurately characterize (hazardous or non-hazardous) your stabilized waste piles. If improperly conducted, valuable time and resources may be wasted by contractors, generators and consultants. The ...

Determination of heavy metals in roadside soil from Sapanca Area Highway, Turkey
This paper describes the determination of lead and nickel in soil samples from Kinali-Sakarya highway side, near Lake Sapanca. Lake Sapanca is the drinking water source for Sakarya city and its environment. This highway runs between Ankara and Istanbul and carries a heavy traffic volume. Soil samples were taken from different distances from the highway once every two months for a year. Three ...

Tests show surfactant-based technology effective in removing PFAS from soil and groundwater
In recent years, several major corporations, including M, DuPont, and Chemours (a DuPont spinoff ), have reached major settlements with municipal governments and other plaintiffs, agreeing to spend billions of dollars to remove PFAS from their pro- duction processes, products and the environment. A substantial amount of these settlement funds will go towards helping water treatment facilities to ...

Mapping Sand Unit Thickness for Construction Aggregate in North Carolina - Case Study
In August 2015, Pyramid Environmental was contracted to estimate the cubic yards of sandy soil valuable as a construction aggregate on the 230 acres of undeveloped land in North Carolina. Purpose The purpose of the electrical resistivity survey was to quantify the lateral extents and approximate depth of sandy soils near the ground surface. The client wanted to understand the potential of the ...

Assessing natural contents of hazardous metals in soils by different analytical methods and its impact on environmental legislative measures
A variety of analytical techniques are commonly used to assess natural metal concentrations in soils. Although the choice of the analytical procedure may appear to be an unimportant issue, through an example from the Po Plain we document that for specific hazardous metals the arbitrary choice between separate analytical techniques may have contrasting legislative implications. Comparative ...

Sampling and On-Site Analytical Methods for Volatiles in Soil and Groundwater - Field Guidance Manual
Abstract: Volatile organic compounds (VOCs) are among the most frequently identified contaminants in soil and groundwater samples obtained during the investigation of suspected hazardous waste sites. Because some VOCs and their degradation products are potentially mutagenic, carcinogenic, or teratogenic, their concentrations in these two matrices are key factors in the risk assessment process. ...

Feasibility of Soil Dust Source Apportionment by the Pyrolysis-Gas Chromatography/Mass Spectrometry Method
This study tested the feasibility of using pyrolysis (Py)-gas chromatography (GC)/mass spectrometry (MS) to obtain organic chemical species data suitable for source apportionment modeling of soil-derived coarse particulate matter (PM10) dust on ambient filters. A laboratory resuspension apparatus was used with known soils to generate simulated receptor filter samples loaded with 0.4 mg of ...

Specific PCR Assays for the Detection and Quantification of DNA from the Biocontrol Strain Trichoderma harzianum 2413 in Soil
Strain identification in situ is an important factor in the monitoring of microorganisms used in the field. In this study, we demonstrated the use of sequence-characterized amplified region (SCAR) markers to detect genomic DNA from Trichoderma harzianum 2413 from soil. Two primers (SCAR A1/SCAR A1c) were tested against DNA of 27 isolates of Trichoderma spp. and amplified a 990-bp fragment from T. ...

Impact of sedimentation on wetland carbon sequestration in an agricultural watershed
Received for publication January 9, 2008. Landscape redistribution of soil C is common within agricultural ecosystems. Little is known about the effects of upland sediment deposition on C dynamics within riparian wetlands. To assess sedimentation impact, we obtained profile samples of wetland soil and used the combination of 137Cs, 210Pb, and 14C chronological markers to determine rates of C ...
