Interaction profile for lead, manganese, zinc, and copper.

Environmental toxicology and pharmacology

Roney N, Colman J.
PMID: 21782753
Environ Toxicol Pharmacol. 2004 Dec;18(3):231-4. doi: 10.1016/j.etap.2004.01.008.

This interaction profile discusses and evaluates the evidence for joint toxic action among lead, manganese, zinc, and copper. The interaction profile recommends how to incorporate concerns about possible interactions or additivity into public health assessments of hazardous waste sites...

Organic interference of solidified/stabilized hazardous wastes.

Environmental monitoring and assessment

Eaton HC, Walsh MB, Tittlebaum ME, Cartledge FK, Chalasani D.
PMID: 24254184
Environ Monit Assess. 1987 Sep;9(2):133-42. doi: 10.1007/BF00394346.

Liquid hazardous waste disposal in landfills is usually allowed only after solidification/stabilization. Although various procedures are commonly practiced, little is known about the mechanism(s) of the processes. A particular problem is the interference of organics. Small amounts of organics...

Detection of metal contamination in wild asparagus near a waste disposal site.

Environmental monitoring and assessment

Brandt CA, Rickard WH.
PMID: 24193895
Environ Monit Assess. 1996 Dec;43(3):201-16. doi: 10.1007/BF00394449.

Estimating contaminant distributions in environmental media is necesary to evaluate human and ecological hazards. Because of uncertainties in release histories and transport, traditional sampling and statistical techniques applicable to the experimental sciences may not be suitable for exploratory studies...

COD and TOC analysis of leachate from a solidified organic waste.

Environmental monitoring and assessment

Faschan A, Tittlebaum M, Cartledge F, Eaton H.
PMID: 24226952
Environ Monit Assess. 1992 Sep;22(3):199-212. doi: 10.1007/BF00419569.

Several combinations of binders and absorbent additives were utilized to solidify a typical organic waste, API Separator sludge. The effectiveness of the materials was based on the waste leachability from the solidified samples. COD and TOC analyses were used...

Measurement of high-molecular-weight polycyclic aromatic hydrocarbons in soils by particle beam high-performance liquid chromatography-mass spectrometry.

Journal of the American Society for Mass Spectrometry

Pace CM, Betowski LD.
PMID: 24214357
J Am Soc Mass Spectrom. 1995 Jul;6(7):597-607. doi: 10.1016/1044-0305(95)00249-D.

Polycyclic aromatic hydrocarbons (PAHs) comprise a class of potentially hazardous com- pounds of concern to the U.S. EPA. The application of particle-beam (PB) liquid chromatography-mass spectrometry (LC-MS) to the measurement of high-molecular-weight PAHs was investigated. Instrument performance was evaluated...

Characterizing soils for hazardous waste site assessments.

Environmental monitoring and assessment

Breckenridge RP, Keck JF, Williams JR.
PMID: 24213742
Environ Monit Assess. 1994 Apr;30(2):113-38. doi: 10.1007/BF00545618.

This paper provides a review and justification of the minimum data needed to characterize soils for hazardous waste site assessments and to comply with the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). Scientists and managers within the regulatory...

Effect of aspect ratio and surface defects on the photocatalytic activity of ZnO nanorods.

Scientific reports

Zhang X, Qin J, Xue Y, Yu P, Zhang B, Wang L, Liu R.
PMID: 24699790
Sci Rep. 2014 Apr 04;4:4596. doi: 10.1038/srep04596.

ZnO, aside from TiO2, has been considered as a promising material for purification and disinfection of water and air, and remediation of hazardous waste, owing to its high activity, environment-friendly feature and lower cost. However, their poor visible light...

Hydrolysis and recycling of urea formaldehyde resin residues.

Journal of hazardous materials

Liu M, Wang Y, Wu Y, Wan H.
PMID: 29775883
J Hazard Mater. 2018 Aug 05;355:96-103. doi: 10.1016/j.jhazmat.2018.05.019. Epub 2018 May 16.

Urea formaldehyde (UF) resin residues generate many poisonous chemicals during traditional disposal technologies for organic hazardous wastes. In this study, hydrothermal hydrolysis was developed to decompose, remove, and recycle cured UF resin. Under 140 °C and 2 h of...

Fuel oil generated from the cogon grass-derived Al-Si (.

Heliyon

Sangpatch T, Supakata N, Kanokkantapong V, Jongsomjit B.
PMID: 31463407

This research investigated pyrolysis as a potential method to manage plastic waste in Sichang Island, Thailand. Pyrolysis was chosen to convert waste plastic into fuel oil using Al-Si catalysts derived from cogon grass. The study consisted of three stages....

A Facile Method for the Removal of dsRNA Contaminant from In Vitro-Transcribed mRNA.

Molecular therapy. Nucleic acids

Baiersdörfer M, Boros G, Muramatsu H, Mahiny A, Vlatkovic I, Sahin U, Karikó K.
PMID: 30933724

The increasing importance of in vitro-transcribed (IVT) mRNA for synthesizing the encoded therapeutic protein in vivo demands the manufacturing of pure mRNA products. The major contaminant in the IVT mRNA is double-stranded RNA (dsRNA), a transcriptional by-product that can...

Emission characteristics and vapour/particulate phase distributions of PCDD/F in a hazardous waste incinerator under transient conditions.

Royal Society open science
