Ideally, a Systems Toxicology (ST) approach is aimed at by (eco)toxicologists, i.e. multidisciplinary area incorporating classical toxicological concepts with omics technologies, and the understanding of this through computational data sciences, chemistry, mathematics, physics modelling. As outlined in several public reports (e.g. from ECHA-European Chemical Agency EFSA-European Food Safety Aut...

Due to the use of a limited number of species and subchronic exposures, current ecological hazard assessment processes can underestimate the chronic toxicity of environmental contaminants resulting in adverse responses of sentinel species. Several incidences where sentinel species have responded to the effects of chronic exposure to ambient levels of environmental contaminants are discussed, in...

BACKGROUND Lead poisoning is a common environmental health hazard in developing countries. Incidences of lead poisoning are seen in all age groups, especially in adults working in lead-based industries, where many still remain unaware of the adverse effects of exposure to unusually high levels of lead. METHODS We report the case of an adult battery worker, who initially received symptomatic t...

An empirical modeling of road related and non-road related landslide hazard for a large geographical area using logistic regression in tandem with signal detection theory is presented. This modeling was developed using geographic information system (GIS) and remote sensing data, and was implemented on the Clearwater National Forest in central Idaho. The approach is based on explicit and quantit...

drought is a natural hazard that has significant impact on economic, agricultural, environmental, and social aspects. in the present study details analysis of rainfall data has been carried out for the years 1981-2011. standard precipitation index (spi) has been used to evaluate the precipitation deficit in the karun watershed of iran. the results indicated that 1981-82,82-83,83-84,84-85,88-89,...
