Should I replace my plastic kitchen and personal care items?
What the experts say

Do not rush to replace
What it rests onHer stated risk formula, that risk equals hazard multiplied by exposure, applied through worked exposure calculations in adjacent product categories; and her analysis of methodological failures in microplastics detection.

Overview
Gomberg's case is strongest for repeated high-temperature contact with recycled black plastic, and for children. Wong's case is about the general adult population at ordinary exposures, and about the cost of an evidence-free swap: money, and in her life cycle argument, a worse environmental outcome. Neither is arguing about the other's population.
Where they agree
Both accept the detections. Wong states that we use too much plastic and that there are real concerns about the health impacts of microplastics; her objection is to the inference from detection to personal harm, and to the specific swap. Both would agree that ingredient transparency in consumer products is poor.
What would settle it
An exposure study rather than a content study: measuring what actually migrates from these products into food or skin under normal use, and comparing it with a reference dose.
The Chemosphere paper's own corrected exposure figure moved twice in the wrong direction for Gomberg's case, from 34,700 ng/day to 7,900 ng/day against a corrected reference dose of 420,000 ng/day, and a third independent measurement would settle more than another round of product testing.
