Biology and Water Pollution Control
The Gm and In V allotypes of serum are inherited in Mendelian fashion and their existence imposes important constraints on current theories of immunoglobulin synthesis. The incidences of particular factors vary markedly with different population groups, a fact of anthropological interest. In medico-legal investigations allotypes can aid in cases of disputed parentage (both paternal and maternal...
متن کاملGlobal Gray Water Footprint and Water Pollution Levels Related to Anthropogenic Nitrogen Loads to Fresh Water.
This is the first global assessment of nitrogen-related water pollution in river basins with a specification of the pollution by economic sector, and by crop for the agricultural sector. At a spatial resolution of 5 by 5 arc minute, we estimate anthropogenic nitrogen (N) loads to freshwater, calculate the resultant gray water footprints (GWFs), and relate the GWFs per river basin to runoff to c...
