Analyze the Herbicide Sulcotrione’s Impact on Consumers

In the U.S., China and Europe, sulcotrione is used as an herbicide for farming. Sulcotrione works to inhibit 4-hydroxyphenylpyruvate dioxygenase, better known as HPPD, in plants, the journal Herbicides, Theory and Applications explained. This triketone-type herbicide is commonly used on weeds and other unwanted vegetation to protect crop grasses like wheat, barley, and corn or maize.
Like many pesticides used in commercial farming operations, it is important that the chemicals designed for effectively killing invasive plants are not also harmful for human consumption, as they may be absorbed by food through the soil. Here are a few of the most prominent studies done of the herbicide and how it reacts with humans and the environment.
European Chemicals Agency study
In 2011, the European Chemicals Agency Committee for Risk Assessment adopted the opinion that sulcotriones fit the category of a substance that is a hazard to aquatic plant life and should be labeled as such.
"Sulcotrione therefore fulfills the criteria for classification as aquatic environmental hazard acute category 1, H400 and aquatic environmental hazard chronic category 1, H410." the ECHA report found after analyzing an array of data.
The chemical's degradability in varied PHs, its ecotoxicity, and bioaccumulation were considered when deciding that it should be labeled differently and concentration restrictions should be put in place.
During the course of researching the herbicide's effects, researchers concluded that there were no notable health detriments noticed to humans. Monkeys and rats passed the chemical quickly through their waste, mostly as urine.
The only area where danger was observed was in plants in a water ecosystem. The report explained that this was logical because, "the relative sensitivity of aquatic plants reflects the intended function of the substance (a herbicide)."
Other relevant studies
There are several other studies that also analyze sulcotrione's impact, some of which may have been used in the ECHA's decision.
A 2002 study from scientists at of the Korea Research Institute Chemical Technology looked at diuron, fluridone, or sulcotrione in relation to chlorophyll and carotenoid reduction. They found evidence that the stopping electron transport by limiting the amount of plastoquinone in plants is a reason for the herbicide's effectiveness.
Researchers from Université Blaise-Pascal in France found in 2009 with photochemical experiments that sulcotriones became more toxic to the environment than with itself and its metabolites alone. The researchers suggested that the material be used in further experiments.
Like many herbicides, sulcotrione can be harmful to the environment in certain circumstances, past the desired effects. This underscores the importance of pesticide standards testing and proper use of an herbicide, or there may be unintended negative consequences for the area around the farm.
