List of prominent ECs categorized based on their current attention and potential concern

The table categorizes ECs into three groups: those currently in the spotlight (highlighted in blue), those with potential concern but less current attention (highlighted in purple), and contaminants of the past that are now emerging with renewed concern. Some ECs have been identified for control by various environmental regulatory agencies, including the Ministry of Ecology and Environment of the People’s Republic of China,³² the European Union,²⁹ and the US EPA.³⁷ It is important to note that this table provides only a selection of examples for each category, and there are many more ECs within each group.^{29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49}
