Six samples were analyzed and the contents of the elements found were: 28.7 41.3 µg kg−1 for arsenic, 86.4 480.1 µg kg−1 for selenium and 32.6 52.4 µg kg−1 for antimony.
A total of 167 genes (209 probesets) were significantly differentially expressed in the metal-exposed cells; 62 of these genes were dysregulated in the arsenic-exposed cells and 105 in the cadmium exposed cells (Table 1 see Additional File 1: Arsenic-modulated genes, Additional File 2: Cadmium-modulated genes).
During decomposition, G. pulex as a ecosystem engineer facilitated significantly the enrichment of magnesium (250%), manganese (560%), cobalt (310%), copper (200%), zinc (43%), arsenic (670%), cadmium (100%) and lead (1340%) into small particle sizes.
We exposed zebrafish embryos at 0.25 1.25 hr postfertilization to 10 or 100 ppb arsenic for 24 or 48 hr.

4 Arsenic in drinking water: The highly toxic chemical which is used to make certain alloys used in the manufacturing industry, can get into the drinking water supply, particularly in ground water.
Most tubewells contain >50 μg L-1 arsenic in red areas and <50 μg L-1 in green areas.
