MEA carbon dioxide scrubbing is also used to regenerate the air on submarines. Solutions of MEA in water are used as a gas stream scrubbing liquid in amine treaters. [21] For example, aqueous MEA is used to remove carbon dioxide (CO 2) and hydrogen sulfide (H 2 S) from various gas streams; e.g., flue gas and sour natural gas. [22]
Besides the identified input from human medicine, there appears to be diffuse pollution from pharmaceuticals used in other areas such as agriculture. Investigations in Germany, France and Scotland showed traces of PPCPs upstream of waste water treatment plant effluents to rivers. The noPILLS report found that "the whole medicinal product chain ...

The concept is also used in water supply and food production, and is generally understood as a series of treatment steps and other safety precautions to prevent the spread of pathogens. The degree of treatment required for excreta-based fertilizers before they can safely be used in agriculture depends on a number of factors.
The use of GMO crop plants engineered for herbicide resistance can also indirectly increase the amount of agricultural pollution associated with herbicide use. For example, the increased use of herbicide in herbicide-resistant corn fields in the mid-western United States is decreasing the amount of milkweeds available for monarch butterfly larvae.
As they are present in food consumed in human diets and in plants used in traditional medicine of several cultures, their role in human health and disease is a subject of research. [ 1 ] [ 5 ] [ 6 ] [ 7 ] : 104 Some phenols are germicidal and are used in formulating disinfectants.
