TCPyor3,5,6-trichloro-2-pyridinolis a cyclic hydrocarbon, specifically achlorinatedversion of2-pyridone.
Pesticides can be a precursor to TCPy. TCPy is a metabolite of the herbicidetriclopyr,[1]and of the insecticideschlorpyrifosandchlorpyrifos-methyl.A study in Massachusetts reported a correlation between exposure to TCPy and lowertestosteronelevels in men.[2]According to this source, exposure is "widespread" and of "potential public health importance".
