Answer:

Given below is the answer

Explanation:

Triazine class pesticide atrazine is chlorinated. It is used to control pre-emergence broadleaf weeds in turf, such as golf courses and residential lawns, as well as in crops including maize (corn), soybeans, and sugarcane. Atrazine is one of the most commonly used herbicides in American, Canadian[4, 4], and Australian agriculture, and Syngenta is its main manufacturer. When the EU discovered groundwater levels surpassing the regulatory limits in 2004 and Syngenta was unable to demonstrate how to prevent this or that these levels were safe, its usage was outlawed in the EU. 

Atrazine was shown to be the most frequently occurring pollutant, according to at least two important Canadian farm well investigations.

Atrazine was the most frequently found herbicide affecting water as of 2001.
