supercritical fluid extraction (scfe) is a soil remediation technology. at present, only a few companies are using from this method, all of which are technical based on conventional methods of extraction such as soilex solvent extraction. because of the hard enforcement of environmental conservation law, using green technology seems imperative. this paper endeavors to carry out the feasibility ...

The final processing and disposal the waste occurs at Final Disposal Facility (TPA). Because rubbish heaps include a variety of contaminants produce air pollution, landfills can have an impact on environment's quality. This study intends to identify contrast outcomes analysis quality in residents' homes near Piyungan TPA location, which is 50 m, 350 650 1000 m from TPA, with standards according...

Widespread soil contamination threatens living standards and weakens global efforts towards the Sustainable Development Goals (SDGs). Detailed mapping is needed to guide effective countermeasures sustainable remediation operations. Here, we review visible infrared reflectance spectroscopy (VIRS) based detection methods in combination with machine learning. To date, proximal, airborne spaceborne...

ROBERT L. BUSH, JR.: Accumulation of fine particles onto three coniferous species. There is concern that airborne contaminants generated by applying sewage sludge to land for agricultural purposes may pose significant health risks to nearby residents. Polybrominated diphenyl ethers (PBDEs) have been shown to be both a persistent class of organic chemicals in sewage sludge and to accumulate in t...

To improve understanding of possible connections between airborne tungsten and public health, size and geography of airborne tungsten particles collected in Fallon, Nevada, and Sweet Home, Oregon, were compared. Both towns have industrial tungsten facilities, but only Fallon has experienced a cluster of childhood leukemia. Fallon and Sweet Home are similar to one another by their particles of a...

Emerging contaminants are distributed in to the environment from various anthropogenic activities. These Emerging contaminants (ECs) are mainly composed of products, such as pharmaceuticals, personal care products (PCPs), surfactants, plasticizers, pesticides etc. The present conventional system of waste treatment are not designed to treat these contaminants. Complex structure of these pollutan...

BACKGROUND During the Vietnam War, approximately 20 million gallons of herbicides, including ~10.5 million gallons of dioxin-contaminated Agent Orange, were sprayed by about 34 UC-123 aircraft that were subsequently returned to the United States, without decontamination or testing, to three Air Force reserve units for transport operations (~1971-1982). In 1996, observed dioxin contamination led...

Photoreactivation was observed in airborne Mycobacterium parafortuitum exposed concurrently to UV radiation (254 nm) and visible light. Photoreactivation rates of airborne cells increased with increasing relative humidity (RH) and decreased with increasing UV dose. Under a constant UV dose with visible light absent, the UV inactivation rate of airborne M. parafortuitum cells decreased by a fact...
