TCPy or3,5,6-trichloro-2-pyridinol is a cyclic hydrocarbon, specifically achlorinated version of2-pyridone.
Pesticides can be a precursor to TCPy. TCPy is a metabolite of the herbicidetriclopyr,[1] and of the insecticideschlorpyrifos andchlorpyrifos-methyl. A study in Massachusetts reported a correlation between exposure to TCPy and lowertestosterone levels in men.[2] According to this source, exposure is "widespread" and of "potential public health importance".
