A further example of ecosystem services is the biologically mediated nitrogen cycling in soils. Nitrogen (N) is essential for plant growth, and plants convey many of the services derived from soils. Macro- and meso-invertebrates initiate decomposition of soil organic matter by fragmentation, ingestion...
Anthropogenic addition of reactive nitrogen (Nr) to the biosphere is increasing globally and some terrestrial ecosystems are suffering from a state of excess Nr for biological nitrogen (N) demand, termed N saturation. Here, we review the ecological risks in relation to N saturation and prospective...
The combined effects are estimated according to the hazard index (HI), which shows the health risks associated with the consumption of these bivalves and vegetable species. Therefore, continuous and excess consumption for a lifetime of more than 70 years has a probability of target cancer risk....
By 1982, the International Olympic Council had developed a test for the detection of excess levels of testosterone in athletes, known as the "Testosterone: Epitestosterone test". In this test, levels of testosterone vs/ epitestosterone are measured, and if the testosterone level is 6x that of ...
Gases are neither combustible nor toxic that contains refrigerant gases/liquids used for freezing and velocity energies, such as nitrogen, neon, and carbon dioxide. Toxic gases Gases lead to the expiration of the source or, if bitten, seriously damage anthropological well-being. Examples are fluorin...

The analysis was conducted in positive mode with the optimized capillary voltage of 1.5 kV and the desolvation and source temperatures of 400 ℃ and 150 ℃, respec- tively. The desolvation gas flow was 650 L/h. Nitrogen was used as the nebulizing and desolvation gas. The colli...
of biochemical oxygen demand caused water pollution; one in six is at high risk from nitrogen caused pollution, and one in four from phosphorous pollution (International Food Policy Research Institute & Veolia, 2015). In the whole South Asian region with a population of more than 1.7 billion ...
