A New Method for Mixed Matrix Composite Membranes Preparation Using Direct Spray‐Coating Technique

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT The development of membranes has evolved over the last years as an effective CO2 separation technology to fight the environmental impact of post‐combustion processes. In this regard, the upgrade of conventional polymers has been approached through different strategies to overcome their permeance‐selectivity trade‐off.

Subchronic Exposure to Arsenic and Nickel Triggers Nitrosative Stress and Histological Alterations in the Rat Liver

Journal of Applied Toxicology, EarlyView.
ABSTRACT Environmental exposure to heavy metals poses a threat to human health. Several studies documented harmful effects on the liver after arsenic and nickel exposure at concentrations beyond permissible limits. Nevertheless, the impact of a simultaneous exposure to both elements on hepatic biochemistry and histology remains unelucidated. Therefore,

Human Health Risk Assessment From Exposure to Toxic Metals in Soils and Leafy Vegetables in Smallholder Farms of Northeastern Brazil

Journal of Applied Toxicology, EarlyView.
ABSTRACT This study assessed human health risks associated with exposure to potentially toxic metals (PTMs) in soils and leafy vegetables cultivated in smallholder agricultural systems in Northeastern Brazil. Soil and vegetable samples were collected from 18 agricultural areas and analyzed for cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), nickel
