The environmental challenges require internationally accepted standards, in which limits and test methods are defined. Metrohm instruments and applications comply with a lot of international environmental standards. Substances introduced into the environment are distributed among the environmental compartments water, soil (sediment), and air, as well as among the organisms living in them (biosphere). Only if we know the type and quantity of these contaminants can we protect the environment and its ...

Air quality monitoring may involve measuring particle mass (PM), particle number concentrations (PN), particle size, or collecting particles for later chemical analysis. Air quality monitoring efforts are usually driven by governmental regulation, but may also be motivated by a neighborhood concern or scientific interest. These measurements are performed by researchers in industries or institutions, but they may also be performed by local advocacy groups. When combined with other information (such as weather data, ...

Brick kilns, as well as other plants such as ceramics manufacturers and fertiliser producers, are a major producer of hydrogen fluoride (HF) emissions. HF is highly reactive gas and seriously damaging to human health, so has strict emissions limits imposed by legislation. In addition to the effects to humans, emissions have been found to damage crops and fruit trees, as well as the general environment. The brick industry strives to reduce the amount of HF emissions and numerous projects have been carried out into ...
