High lead exposure in two leaded bronze ingot foundry workers

BACKGROUND Awareness about lead poisoning in South Korea has increased; however, occupational exposures occurring in small-scale businesses have not been thoroughly investigated. We report two cases of high lead exposure in a leaded bronze ingot foundry. CASE PRESENTATION Two employees, a 54-year-old primary operator and a 46-year-old assistant, at a small-scale metalworking company who had b...

Chemical Investigation of Two Ancient Bronze Statuettes Found in Greece

Shocked molecular hydrogen from RNO 91

We report the detection of the H2 v=1-0 S(1) line at 2.122μm, from RNO91 in the L43 dark cloud, which is known to be a T Tauri star surrounded by a 1700AU disk structure (containing ices) and a weak outflow. The non-detection of the H2 v=2-1 S(1) line at 2.247μm suggests shock excitation rather than fluorescence. The emission is extended spatially up to 9 in the north-south direction. The line ...

Iron status of adolescent girls from two boarding schools in southern Benin.

Iron deficiency (ID) is the most prevalent micronutrient deficiency in the world, particularly in developing countries. Blood samples and a qualitative FFQ on Fe- and vitamin C-rich foods were obtained in 180 adolescent girls aged 12 to 17 years living in two boarding schools from south Benin. ID, defined as serum ferritin either 73 micromol/l or transferrin saturation<20%, was found in 32% of ...

Monte Carlo simulation of two 106Ru eye plaques in a new mathematical human eye model

  BEBIG Ruthenium-106 ophthalmic plaques have been used for treatment of uveal melanoma, retinoblastoma, melanoma of the iris and other special applications for many years. The plaques consist of a thin film of 106Ru, a beta emitter, encapsulated in pure silver. The present work proposes a new mathematical eye model for ophthalmic brachytherapy dosimetry. This new mod...
