Comprehensive analysis of renal arsenic accumulation using images based on X-ray fluorescence at the tissue, cellular, and subcellular levels.

Exposure to arsenic (As) through drinking water results in accumulation of As and its methylated metabolites in several organs, promoting adverse health effects, particularly potential development of cancer. Arsenic toxicity is a serious global health concern since over 200 million people are chronically exposed worldwide. Abundant biochemical and epidemiological evidence indicates that the kidney is an important site of uptake and accumulation of As, and mitochondrial damage plays a crucial role in arsenic toxicity.

An integrated approach for assessing the migration behavior of chlorpyrifos and carbaryl in the unsaturated soil zone.

Chlorpyrifos (O, O-diethyl O-3,5,6-trichloropyridin-2-yl phosphorothioate) and carbaryl (1-naphthyl methylcarbamate) are often applied concurrently as insecticides in food production. The aim of this study was to research their migration behavior in a real environment. We researched the leaching of both pesticides by setting up field lysimeters on a farm with the typical soil used in fruit production today.

Arsenic absorption and excretion in chronically exposed developing toad Rhinella arenarum.

We assessed the toxicodynamics of As in developing Rhinella arenarum toad embryos and larvae exposed from fertilization to 0.01-10mgAsL. We determined As content in toad embryos and larvae by X-ray fluorescence spectrometry.
