美国HSDB引用文献：

*A highly characteristic dermatitis confined to the scrotum, inguinal area, and nasolabial folds may follow moderate occupational exposure to paris green. The lesions begin with erythema, frequently become eczematous and weeping, & may start to heal with ... black scab. A sensitization reaction may be involved ... In less acute cases, hyperkeratosis, hyperhidrosis, or melanosis may occur. ... The hyperpigmentation is most marked on surfaces exposed to light. ... There may be a speckled depigmentation of pigmented areas giving the so called raindrop appearance. [R32]

*Sixty four workers in a malaria control unit sprayed Baytex, Temephos (both organic thiophosphates), and paris green in oil for 5-6 hr per day without use of protective clothing, face masks, or gloves. Fourteen members of the group, aged 24-42 yr with exposure in the range 1-8 yr, had macular involvement. Symptoms incl visual impairment, dislike of bright light, night blindness, black dots in front of the eyes, and blurring of vision. Visual acuity was reduced in 9 subjects. Macular degeneration was characterized by areas of perifoveal depigmentation, dull foveal reflex, and bilaterial lesions. [R33]

*TOXICITY PRIMARILY RESULT OF ARSENIC CONTENT. [R1]
