Mixtures of environmental contaminants and diabetes

Science of The Total Environment, 2023
Many studies have been published on the relationships between different environmental contaminants and diabetes. In these studies, the environmental contaminants have most often been evaluated one by one, but in real life we are exposed to a mixture of contaminants that interact with each other.The major aim of this study was to see if a mixture of ...

Rhamnolipid biosurfactant mixtures for environmental remediation

Water Research, 2008
This study investigated the efficiency of rhamnolipid biosurfactant and synthetic surfactant mixtures for improving the interfacial activity of the surfactant system against several light non-aqueous-phase liquids (LNAPLs). Since the rhamnolipid biosurfactant proved to be relatively hydrophilic, we hypothesized that mixtures of rhamnolipid ...

Bayesian variable selection for understanding mixtures in environmental exposures

Statistics in Medicine, 2021
Social and environmental stressors are crucial factors in child development. However, there exists a multitude of measurable social and environmental factors—the effects of which may be cumulative, interactive, or null. Using a comprehensive cohort of children in North Carolina, we study the impact of social and environmental variables on 4th end‐of ...

Activation of two environmental mixtures by plant S9

Mutation Research/Genetic Toxicology, 1989
Nitrated and ozonized pyrene mixtures were assayed for their mutagenic activity in the presence or absence of pea S9 using Salmonella typhimurium TA98 as the indicator organism. The plant enzymes increased the mutagenic response of these mixtures above that obtained in the absence of S9.

Pharmaceutical Mixtures: Still A Concern for Human and Environmental Health

Current Medicinal Chemistry, 2020
In the present work, recent data on the sources, occurrence and fate of human-use pharmaceutical active compounds (PhACs) in the aquatic environment have been reviewed. Since PhACs and their metabolites are usually present as mixtures in the environment at very low concentrations, a particular emphasis was placed onto the PhACs mixtures, as well as ...

Modeling mixtures interactions in environmental toxicology

Environmental Toxicology and Pharmacology
In the environment, organisms are exposed to mixtures of different toxicants, which may interact in ways that are difficult to predict when only considering each component individually. Adapting and expanding tools from pharmacology, the toxicology field uses analytical, graphical, and computational methods to identify and quantify interactions in ...

Nitro Compounds in Environmental Mixtures and Foods

1985
Nitropyrenes (NPs) are the most potent mutagens that have been detected in environmental pollutants such as airborne particulates (Tokiwa et al., 1981b), car exhaust emissions (Lee et al., 1980; Gibson et al., 1981; Pederson and Siak, 1981; Schuetzle et al., 1981), photocopies (Lofroth et al., 1980; Rosenkranz et al., 1980), wastewater from gasoline ...
