Kampani ya Huisong Pharmaceuticals yalabadira mfundo za EPA ndipo ikupitirizabe kulamulira mosamalitsa kuyesa zotsalira za mankhwala ophera tizilombo m'Dipatimenti yathu ya Ubwino kuti zitsimikizire kuti zinthu zonse zotumizidwa ku US zilibe chlorpyrifos.
Chlorpyrifos yakhala ikugwiritsidwa ntchito kwa zaka zopitilira 40 ndipo idalembetsedwa kuti igwiritsidwe ntchito m'maiko pafupifupi 100 pa mbewu zopitilira 50.Ngakhale chlorpyrifos idayambitsidwa kuti ilowe m'malo mwa mankhwala ophera tizilombo a organophosphorus, pali kafukufuku wochulukirachulukira wosonyeza kuti chlorpyrifos ikadali ndi zotsatirapo zoyipa zomwe zimatha kukhala kwanthawi yayitali, makamaka kawopsedwe kamene kamafalitsidwa kwambiri mu neurodevelopmental toxicity.Chifukwa cha zinthu zowopsa izi, Chlorpyrifos ndi chlorpyrifos-methyl akhala akuyenera kuletsedwa ndi European Union kuyambira 2020. Momwemonso, kukhudzana ndi chlorpyrifos kungayambitse kuwonongeka kwa ubongo ku ubongo wa ana (wogwirizana ndi neurodevelopmental toxicity), California Environmental Protection Agency. adagwirizananso ndi wopanga kuti akhale ndi chiletso chokwanira pa kugulitsa ndi kugwiritsa ntchito chlorpyrifos kuyambira pa February 6, 2020.
