Health Effects
Drinking water standards for simazine have been developed for potential hematological (blood system) toxicity. Additional health protective benchmarks have been developed based on adverse health effects that are not specific to a single organ or system (i.e., reduced body weight).
Affected Organs & Systems:
Common Sources
- Simazine primarily enters the environment and drinking water sources through runoff and seepage from areas where it is used as an herbicide. It may also be released from sites where it is produced and stored.
How to Remove It
Water filters certified under the following NSF standards are effective at removing Simazine:
