Global Pesticides Release Database
The Global Pesticides Release Database (GloPeRD) was established in recognition of the increasingly urgent needs of the national and international community for accurate and complete usage, emission and residue data for pesticides.
There is considerable evidence that persistent organochlorine pesticides circulate globally and accumulate in remote areas like the Arctic. Establishing the sources of pollutants and their emissions and residues are first steps towards reducing their levels in the environment. The analysis of emission trends is also important in developing ways to manage such chemicals more effectively.
This research is a contribution to the Canadian Arctic research through the Northern Contaminants Programme (NCP). The NCP was established to study the presence of contaminants in the Arctic ecosystem. The three main contaminants groups of concern are persistent organic pollutants (including organochlorine pesticides), heavy metals and radionuclides. Many of these contaminants have no Arctic sources and yet some are found at high levels in animals at the top of the Arctic food chain and in humans.
This research is also a contribution to the Global Emissions Inventory Activity (GEIA), a component of the International Global Atmospheric Chemistry core project of the International Geosphere – Biosphere Program.
The GloPeRD database includes the following:
- Surrogate data, in order to grid usage or emission data and to apportion the usage or emission data to each cell. For example, gridded population data sets have been used as surrogates to grid anthropogenic emissions of sulfur, nitrogen, and carbon [Dignon, 1992; Spiro et al., 1992; Kato and Akimoto, 1992; Akimoto and Narita, 1994; Benkovitz et al., 1996; Li et al., 1998]. Gridded cultivation intensity data sets in different scales were used as a surrogate (Li, 1999, 2001; Li et al., 1996; 1999) to map global and regional usage/emissions data of pesticides.
- Emission data, which is used in modelling to understand the sources, occurrence, and pathways of contaminants and to predict how their input and concentrations in the various environmental compartments may change in the future.
Specific data from the GloPeRD database is available and free by contacting the scientific authority, Dr. Yi-Fan Li.
