Haze pollution by anthropogenic emitted particles is a frequent challenge for Beijing air quality in addition to the well-known dust storm events. Man-made air pollution is able to cause hazy conditions reducing the sight range. Since those air quali

Worldwide, West-Bengal is one of the areas most affected by elevated levels of arsenic in groundwater (50-3000 mu g/l). This groundwater does not only endanger humans owing to its use as drinking water. More and above that, irrigation of rice paddies

The aim of this study was to investigate the accumulation of arsenic (As) in and on roots of Zea mays (maize) and Helianthus annuus (sunflower) by means of synchrotron-based micro-focused X-ray fluorescence imaging (μ-XRF). Plant and soil samples we

The Cu–Au rich ores of the Concepcion del Oro mining district, located on the semi-arid Mexican Altiplano, have been mined for over 400 years. The residues of these activities were piled on the banks of the main stream that drains the area. The tai
