Publisher's Synopsis
This volume of the IARC Monographs provides an evaluation of the carcinogenicity of ingested nitrate and nitrite, and the cyanobacterial peptide toxins, microcystin-LR and nodularins. These agents are linked environmentally through the runoff of agricultural fertilizers that increase nitrogen concentrations in surface water and groundwater and that could contribute to cyanobacterial growth in surface water. Moreover, nitrate and nitrite are added to meat and fish for preservation as color fixatives and as flavoring agents. An IARC Monographs Working Group reviewed epidemiological evidence, animal bioassays, and mechanistic and other relevant data to reach conclusions as to the carcinogenic hazard of these agents to humans.
