A global human health risk assessment for octamethylcyclotetrasiloxane (D 4 )

A New Method for Spatial Health Risk Assessment of Pollutants

Background: The area of contaminated lands exposed to the health risk of environmental pollutants is a matter of argument. In this study, a new method was developed to estimate the amount of area that is exposed to higher than normal levels of Cr, Mn, and V. Methods: Overall, 170 soil samples were collected from the upper 10 cm of soil in an arid area in central part of Iran in Semnan Provin...

Identification of metabolites of octamethylcyclotetrasiloxane (D(4)) in rat urine.

Octamethylcyclotetrasiloxane (D(4)) is an industrial chemical of significant commercial importance. In this study, its major urinary metabolites were identified. The urine samples described here were collected from male and female Fischer rats (F-344) administered [(14)C]D(4) i.v. The metabolite profile was obtained using an HPLC system equipped with a radioisotope detector. HPLC analysis was p...

Exposure Assessment to Environmental Pollutants in Human Health Risk Assessment Studies; Overview on New Approaches

Background & objectives: Because of human exposure to various environmental risk factors during the lifetime, the actual exposure estimation has been considered as one of the most important challenges for researchers and decision makers. Considering the contribution of environmental risk factors in the burden of diseases, this study aimed to provide new approaches in exposure assessment filed b...

Derivation of Assessment Factors for Human Health Risk Assessment

Vitamin D for health: a global perspective.

It is now generally accepted that vitamin D deficiency is a worldwide health problem that affects not only musculoskeletal health but also a wide range of acute and chronic diseases. However, there remains cynicism about the lack of randomized controlled trials to support the association studies regarding the nonskeletal health benefits of vitamin D. This review was obtained by searching Englis...
