How PARAQUAT affects humans.

Paraquat is considered the most poisonous herbicide widely in use. As an example: 345 different herbicides are approved for use in Germany and paraquat alone is rated "highly toxic".

Paraquat requires a special label with a skull and cross bone (the international symbol for danger) and the letter T+ for chemicals that can seriously damage a person's health in small doses and might be fatal. Other chemicals with this designation include arsenic or hydrogen cyanide.

Paraquat is highly acutely toxic and enters the body mainly by swallowing, or through damaged skin, but may also be inhaled. One spoon of concentrated paraquat can result in death.
