Different definitions of risk too easily lead to differences in the type and level of risk accepted by varying stakeholders involved in the remediation process and redevelopment of contaminated sites as a whole. This can be rooted in the way risk information is interpreted and evaluated: technical risk definitions are largely evidential and based on engineering or technical contents, whereas so...

Alkylphenol polyethoxylate (APEO) derivatives, such as nonylphenol monoethoxylate (NP1EO), nonylphenol diethoxylate (NP2EO), nonylphenol (NP) and octylphenol (OP), have been detected in the surface water, sediment, food and groundwater of numerous countries. Because groundwater is the main source of water for pig herds, the aim of this study was to measure the concentrations of APEO derivatives...

The aim of the present study was to investigate the effectiveness of whey proteins when mixed with hot-water extracts of Artemisia and Capparis spp. against lipid peroxidation induced by lead acetate in rats. Chemical composition and antioxidant activities of hot-water extracts of Artemisia and Capparis spp., ingested individually or mixed with whey proteins, were estimated and evaluated. Gluta...

Optimizing growth chamber conditions for Arctic lichen biocrusts will create new opportunities to assess and prioritize reclamation techniques given the challenges associated with conducting arctic field work. Our study is first examine optimizing survival of biocrusts, as measured by changes in cover. We assessed effects substrate crossed depth, sterilization, inoculation community composition...

Improved waste management at McMurdo Station, Antarctica beginning in the 1980s has been followed by decreases polycyclic aromatic hydrocarbon (PAH) and metal contamination adjacent marine sediments. However, determining effect of decreased on ecological indicators (macrobenthic fauna) is confounded concurrent changes climate cycles other physical forces. Between 2000 2013, there was a decrease...

In pesticide risk assessment, effect concentrations and dynamics of long-term community-level effects caused by pulse exposures remain to be investigated. This is because long-term experiments are exceptionally rare, and most of the previously investigated communities had low proportions of sensitive long-living species. The aim of the present study was to investigate the effect of a single pul...

Shiga toxin-producing Escherichia coli O157:H7 and Salmonella enterica serovar Typhimurium are important foodborne pathogens capable of forming single-species biofilms or coexisting in multispecies biofilm communities. Bacterial biofilm cells are usually more resistant to sanitization than their planktonic counterparts, so these foodborne pathogens in biofilms pose a serious food safety concern...

Long-term stable mixed chimerism is a rare and poorly understood phenomenon post hematopoietic stem cell transplantation. This study aims to shed light on whether the two hematopoietic systems in patients with mixed chimerism remain functional. Additionally, we investigate possible immunologic differences in these individuals compared to patients with only donor derived immune cells. Patients w...
