An analysis by two US researchers of scientific publications concerning consumer chemicals identified some 1 900 published papers ever and up to the end of 2017, screened down to 342 papers referring to specific chemicals, endpoints or applications. Numbers of publications increased considerably since 2006, increasing to 2014, and then maybe declining somewhat. The most frequently studied chemicals were phthalates, bisphenol-A and PBDEs (brominated flame retardants). Frequency of publications is stated as having “surged” following regulatory changes or exposure incidents (there is no statistical analysis to support this statement). The authors note that most of the identified papers address a small number of chemicals, and suggest that this leaves a knowledge gap for many other chemicals.
