The image of the structure is wrong

It is missing one Chlorine atom on the lower right part of the image. 151.251.254.173 (talk) 07:00, 18 August 2022 (UTC)[reply]

contamination with PCBs

Some manufacturers of phthalo green blue shade, PG 7, are selling the pigment with problematic levels of PCB contamination. Several studies showed that PG 7 was, by far, the largest source of PCBs in paint currently. PCBs are also an issue with disazo pigments like PY 83 but phthalo green is typically much higher in contamination. Outdated literature claims that the PCB problem was rectified but certain nations do not currently have adequate quality control in place. I would add this to the article but I don't have the energy to find the articles and cite them. 107.77.192.142 (talk) 21:38, 24 December 2024 (UTC)[reply]
