Artikel 19

1. Parties shall endeavour to cooperate to develop and improve, taking into account their respective circumstances and capabilities:
a) Inventories of use, consumption, and anthropogenic emissions to air and releases to water and land of mercury and mercury compounds;
b) Modelling and geographically representative monitoring of levels of mercury and mercury compounds in vulnerable populations and in environmental media, including biotic media such as fish, marine mammals, sea turtles and birds, as well as collaboration in the collection and exchange of relevant and appropriate samples;
c) Assessments of the impact of mercury and mercury compounds on human health and the environment, in addition to social, economic and cultural impacts, particularly in respect of vulnerable populations;
d) Harmonized methodologies for the activities undertaken under subparagraphs (a), (b) and (c);
e) Information on the environmental cycle, transport (including long-range transport and deposition), transformation and fate of mercury and mercury compounds in a range of ecosystems, taking appropriate account of the distinction between anthropogenic and natural emissions and releases of mercury and of remobilization of mercury from historic deposition;
f) Information on commerce and trade in mercury and mercury compounds and mercury-added products; and
g) Information and research on the technical and economic availability of mercury-free products and processes and on best available techniques and best environmental practices to reduce and monitor emissions and releases of mercury and mercury compounds.
2. Parties should, where appropriate, build on existing monitoring networks and research programmes in undertaking the activities identified in paragraph 1.
