The Orne River, a tributary of the Moselle River, was highly impacted by industrial activities for more than one century. Land use along the Orne River is highly contrasted, with local specificity from its source to its junction with the Moselle River. The intense industrial activity left behind tons of steelmaking wastes (SMW) on the land surface and within the Orne riverbed.

On the basis of the seasonal variation of planetary boundary layer heights, air mass back trajectory analysis, and year-long time-series data for Pb/Pb, Pb/Pb, Pb/Pb, and Nd/Nd from aerosols collected over a high-altitude station, we demonstrate that anthropogenic Pb transport to the glacierized catchment has a seasonal pattern. The Pb isotope data reveal that during winter, the thinned boundary layer traps up to 10 ± 7% more coal-derived Pb in the IGP.

- The Isotrace CNRS workgroup and the National Research Council of Canada have identified new trace elements and isotopic ratios in AQUA-1 drinking water that were not previously certified.
- They analyzed SLRS-6 river water for quality control and comparison with AQUA-1, as both were sampled from the same area but treated differently.
- The study provides mass fractions for multiple elements and isotopic ratios for strontium and lead, using ICP-MS techniques, with data categorized as consensus or indicative based on availability and uncertainty.
Background: In France, the prevalence of childhood lead poisoning is becoming rare since the avoidance of lead in paints in 1949 and the gradual replacement of water pipes. Chronic lead toxicity is well known and is well correlated to blood lead concentration.
Aim: Here we report a case of severe lead poisoning occurring in a young female child with a pica behavior.
The pollution of natural waters and sediments with metals derived from acid mine drainage (AMD) is a global environmental problem. However, the processes governing the transportation and transformation of AMD metals such as Cd in mountainous areas are poorly understood. In this study, the Cd isotopic composition and Cd concentration of river water and sediments (16 sampling sites) from an AMD-affected river in southern China were determined.
