Aminomethylphosphonic acid is a popular herbicide, which is widely used corn and cotton. It is mainly used in the United States and its used has increased massively from 10,000 mg (150 gr) in 1992 to 80,000 mg (1,200 gr) in 2007.[citation needed] Its use has produced mainly watershed results. It has an extensive history of urban use and ha been shown to carry surface water (thus displacing it). It's even more popular with GM crops as it is even more resistant, with some rare side-effects.[1].

Environmental effects

Aminomethylphosphonic acid is considered to be less harmful to the environments compared to other Herbicides.[1]. It strongly sorbs to the minerals in soil, it has a shorter life-span compared to other herbicides and it has a lower toxicity to mammals, birds and other aquatic life.[1]

Uses

Mississippi

Agriculture in this region is dominated by the production of soya beans and cotton. The climate is sub-tropical, with summer temperature reaching as high as 37C. Rain fall hear exceeds 120mm per month. Water sample collected in this state had a measurable concentration of Aminomethylphosphonic acid with around 130 micro litres per litre of water. Concentrations were the lowest in the winter and at it's highest during April and may.[1][2][3].

Lowa

55% of all water collected in this region had a significant amount of Aminomethylphosphonic acid and 97% had a very siginificant amount of AMPA.[3]. The concentration in this region measured to as high as 250 micro litres. The usage in this region tripled from 2007 to 2008. [2]

Indiana

In 2004 this region had one of the the lowest amount of Aminomethylphosphonic acid, measuring as low as 4.6 microlitres. However, this increased significantly during 2007 and 2008. Predictions conclude the amount used from 2004 to 2007 increased by almost 10X.[2][3].
