Peeled Red Onions, White Onions, Scallions, Shallots and Leeks left Overnight

Does the halacha of not eating onions which were peeled and left overnight apply to the following: red onions, white onions, scallions, shallots and leeks?

(A subscriber’s question)

Rav Belsky, zt”l said the halacha applies to both red and white onions and shallots, but not to leeks and scallions.

This Q&A is a follow-up to a previous Halacha Yomis titled Onions Overnight.
