Postoperative Atrial Fibrillation and Long-Term Risk of Stroke After Isolated Coronary Artery Bypass Graft Surgery

Umberto Benedetto, Mario Gaudino, Arnaldo Dimagli, Stephen Gerry et autres

Background: Postoperative atrial fibrillation (pAF) after coronary artery bypass grafting is a common complication. Whether pAF is associated with an increased risk of cerebrovascular accident (CVA) remains uncertain. We investigated the association between pAF and long-term risk of CVA by performing a …

Soil properties affect the toxicities of 2,4,6-trinitrotoluene (TNT) and hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) to the enchytraeid worm Enchytraeus crypticus

Roman G. Kuperman, Ronald T. Checkai, Michael Simini, Carlton T. Phillips et autres

The authors investigated individual toxicities of 2,4,6-trinitrotoluene (TNT) and hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) to the potworm Enchytraeus crypticus using the enchytraeid reproduction test. Studies were designed to generate ecotoxicological benchmarks that can be used for developing ecological soil-screening levels for ecological risk assessments of …

Toxicities of TNT and RDX to Terrestrial Plants in Five Soils with Contrasting Characteristics

Michael Simini, Ronald T. Checkai, Carlton T. Phillips, Jan E. Kolakowski et autres

Abstract : This study was designed to produce scientifically defensible benchmark data for the development of ecological-based soil screening levels for 2,4,6-trinitrotoluene (TNT) and hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) for terrestrial plants. The physical and chemical properties of different soils may alter the bioavailability and …

Toxicities of TNT and RDX to the Earthworm Eisenia fetida in Five Soils with Contrasting Characteristics

Michael Simini, Ronald T. Checkai, Roman G. Kuperman, Carlton T. Philips et autres

Abstract : Studies were designed to characterize soil physicochemical parameters that can affect the toxicities of 2,4,6- trinitrotoluene (TNT) or hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) to Eisenia fetida earthworms and also to generate ecotoxicological benchmarks for development of ecological soil screening levels (Eco-SSLs) for ecological …

Toxicities of RDX or TNT Freshly Amended or Weathered-and-Aged in Five Natural Soils to the Collembolan Folsomia candida

Carlton T. Phillips, Ronald T. Checkai, Roman G. Kuperman, Michael Simini et autres

Abstract : The toxicities of 2,4,6-trinitrotoluene (TNT) and hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) to Folsomia candida (Collembola) were investigated using an ISO 11267:1998 test. Studies were designed to identify and characterize soil physicochemical parameters that may affect the acute (adult mortality) and chronic (reproduction) toxicities …

Acute and Chronic Toxicities of TNT and RDX to the Enchytraeid Worm, Enchytraeus crypticus, in Natural Soils

Roman G. Kuperman, Ronald T. Checkai, Michael Simini, Carlton T. Philips et autres

Abstract : We investigated individual toxicities of 2,4,6-trinitrotoluene (TNT) and hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) to the potworm Enchytraeus crypticus using the Enchytraeid Reproduction Test (ISO 16387:2004). Studies were designed to identify and characterize the predominant soil physicochemical parameters that affect the acute (mortality) and …

Ecological Soil Screening Levels For Invertebrates at Explosives-Contaminated Sites: Supporting Sustainability of Army Testing and Training

Roman G. Kuperman, Ronald T. Checkai, Michael Simini, Carlton T. Phillips et autres

The Army Strategy for the Environment applies an ecosystem approach to managing natural resources on Army installations. It incorporates the principles of sustainability across the Army into all functional areas. We conducted investigations to develop critical environmental data required for successful management …

Ecological Soil Screening Levels for Plants Exposed to Tnt: Supporting Range Sustainability for Training and Testing

Michael Simini, Ronald T. Checkai, Jan E. Kolakowski, Roman G. Kuperman et autres

Ecological Soil Screening Levels (Eco-SSL) are those screening concentrations of chemicals in soil that present an acceptable risk to ecological receptors. We investigated the ecotoxicity of TNT to the plant species alfalfa (Medicago sativa L.), Japanese millet (Echinochloa crusgalli L. (Beauv.)), and …

Toxicity of a New Polynitramine Energetic Material, CL-20, to the Enchytraeid Worm, Enchytraeus Crypticus, in a Sandy Loam Soil

Roman G. Kuperman, Ronald T. Checkai, Michael Simini, Carlton T. Phillips et autres

In this report, the toxicity of polynitramine energetic material, hexanitrohexaazaisowurtzitane (CL-20), to the soil invertebrate species, Enchytraeus crypticus, was investigated using the Enchytraeid Reproduction Test. The study was designed to develop eco-toxicological benchmark values for the ecological risk assessment of the potential …

Effect of Simulated Weathering and Aging of TNT in Amended Sandy Loam Soil on Toxicity to the Enchytraeid Worm, Enchytreaeus Crypticus

Roman G. Kuperman, Ronald T. Checkai, Michael Simini, Carlton T. Phillips et autres

The U.S. Environmental Protection Agency is developing Ecological Soil Screening Levels (Eco-SSLs) for the ecological risk assessment of contaminants at Superfund sites. Insufficient information for TNT to generate Eco-SSL for soil invertebrates has necessitated standardized toxicity testing to fill the data gap. …
