Environmental Risk from Organic Residues

Nitrogen mineralization from organic residues: research opportunities.

Research on nitrogen (N) mineralization from organic residues is important to understand N cycling in soils. Here we review research on factors controlling net N mineralization as well as research on laboratory and field modeling efforts, with the objective of highlighting areas with opportunities for additional research. Among the factors controlling net N mineralization are organic compositio...

Organic Contaminant Residues in Fishes from Nipigon Bay, Lake Superior

Three species of fish, caught at various distances from a kraft pulp ai:d paper mill effluent discharge in Nipigon Bay, were analyzed for organic contaminants. Fishes from all sites contained residues of polychlorinated biphenyls and DDE. Most samples were also contaminated with hexachlorobenzene and several samples contained phthalic acid esters. From sampling sites close to the mill discharge...

Dry Digestion of Organic Residues

Sustainable development closely links to the context of energy. Replacing fossil fuels with sustainably produced biomass or organic residues will not only be a way to cope with the depletion of fossil fuel resources but also to reduce the CO2 emissions into the atmosphere and therefore minimise the risk of global warming. A large variety of methods of biomass energy conversion are available tod...

Pesticide Residues and Organic Production

This study focused on studies of pesticide residues in organic product. With increasing health and environmental awareness, organic farming has become an integral part of the agricultural policy in many countries. It is the less harmful to human and environment. The target of organic farm is not high quantity of production, but is the high quality. The market value of organic products in Europa...
