Many black plastic kitchen items are made from recycled electronic materials that contain toxic flame retardants and other chemicals.
You probably don’t want any kind of plastics in the kitchen that might come into contact with heat. As a general rule.
That’s true if you are only concerned about microplastics.
What this article states however is that dangerous chemicals might leach out from many black colored plastics without any heat being applied. And it can be from things that you might not be able to control like restaurant takeout containers farming planters, and children’s toys.
I do think the type of plastic might also play a role, like if it’s PP, HDPE, etc. But I have yet to read the study quoted in the article.

FRs have also been documented to migrate from toys into artificial saliva (Brandsma et al., 2022). With migration rates determined from subjecting contaminated toys to artificial saliva to mimic mouthing by children, Brandsma et al. estimated children’s intake at up to 0.22 ng/kg bw/day for BDE-209, 0.88 ng/kg bw/day for 2,4,6-TBP, 0.03 ng/kg bw/day for TTBP-TAZ, and 2.28 ng/kg bw/day for TBBPA. These values were derived from the highest amount of migration detected, but may not represent the worst-case scenario, as Chen et al. (2019) detected greater migration using human volunteers.

Fossil fuels and petrochemicals are destroying our world! 🙁 Scientists talk about us living in the Anthropocene, maybe Anthropopetrocene would be more accurate.
