Danger |
H370 | P308+P311 P260 P264 P270 P321 P405 P501 |
Based on the human evidence: "late progressive polyneuropathy followed by pyramidal findings in a 20-year old agricultural laborer who ingested Isofenphos solution during his work" (HSDB (2003)). Also based on the evidence from animal studies including "delayed neuropathy" (EHC 63 (1986)). The effects on humans are classified into Category 2 as the priority rating of the referenced studies is 2, whereas the effects on experimental animals were observed at dosing levels within the guidance value ranges for Category 1 (nervous system), and thus classified into Category 1. |

Danger |
H372 | P260 P264 P270 P314 P501 |
Based on the evidence from animal studies: "toxic signs, such as salivation and muscle twitching, were observed," "hypoplasia of the testis were observed in several males; some exhibited foci of softening ("degeneration processes") in the brain stem" (JMPR 552, 1982), "pathological lesions, such as severe degeneration of the pathways in the spinal cord and axonal degeneration in the medulla oblongata and cerebellum, which are typical of delayed neuropathy" (JMPR 744, 1986). The effects on experimental animals were observed at dosing levels within the guidance value ranges for Category 1. |
