  • ASTM D6552 - 06(2011) standard practice for controlling and characterizing errors in weighing collected aerosols

    The weighing of collected aerosol is one of the most common and purportedly simple analytical procedures in both occupational and environmental atmospheric monitoring (for example, Test Method D4532 or D4096). Problems with measurement accuracy occur when the amount of material collected is small, owing both to balance inaccuracy and variation in the weight of that part of the sampling medium ...

  • Tracing CO2 elements in the ocean

    The surface waters of the vast Southern Ocean are suffering from 'marine anaemia' – a serious deficiency in the micronutrient iron. Just as iron deficiency negatively affects the health and productivity of humans and other land-based creatures, so it affects the phytoplankton (microscopic marine plants) existing in the oceanic realm. The environmental consequences of this condition restrict ...
