Nutrient pollution, a form of water pollution, refers to contamination by excessive inputs of nutrients.It is a primary cause of eutrophication of surface waters (lakes, rivers and coastal waters), in which excess nutrients, usually nitrogen or phosphorus, stimulate algal growth. [1]
Compton's research focuses on non-point sources of nitrogen pollution, for example, land use and agriculture. [2] Her non-research based work for the EPA mostly consists of connecting these sources to their impacts, and quantify them in ways that people can understand.
Nitrogen dioxide poisoning is the illness resulting from the toxic effect of nitrogen dioxide (NO 2). It usually occurs after the inhalation of the gas beyond the threshold limit value. [1] Nitrogen dioxide is reddish-brown with a very harsh smell at high concentrations, at lower concentrations it is colorless but may still have a harsh odour.

The reports provide guidelines intending to give guidelines to reduce the health effects of air pollution. [2] The guidelines stipulate that PM 2.5 should not exceed 5 μg/m 3 annual mean, or 15 μg/m 3 24-hour mean; and that PM 10 should not exceed 15 μg/m 3 annual mean, or 45 μg/m 3 24-hour mean. [2]
Nitrogen dioxide is poisonous and can be fatal if inhaled in large quantities. [8] Cooking with a gas stove produces nitrogen dioxide which causes poorer indoor air quality. Combustion of gas can lead to increased concentrations of nitrogen dioxide throughout the home environment which is linked to respiratory issues and diseases.
Within the domain of workplace exposure monitoring, it is really important to follow certain standards and methods of doing things to make sure workers stay safe. [4] Particularly, these standards are naturally linked to the monitoring process, forming a strong foundation for safeguarding and protecting worker’s health. [ 11 ]
