RT Report T1 Biological Monitoring of Environmental Contaminants (Plants) - Executive Summary A1 United Nations Environment Programme, K1 biological monitoring K1 pollutant K1 metal K1 marine environment SN 0 905918 290 YR 1986 FD 1986 LK https://wedocs.unep.org/handle/20.500.11822/28974 UL https://wedocs.unep.org/handle/20.500.11822/28974 NO A wide range of contaminants enter terrestrial, freshwater and marine habitats. Concentrations of specific contaminants can be measured by physicochemical methods; however, the response of plants to elevated concentrations is modified by other environmental factors such as moisture and nutrient status, by interactions between contaminants and by the physiological stage of the plants. The integrated effects of these factors and contamination are assessed by monitoring the plants directly. DS UN Environment Document Repository RD Sep 22, 2026
