Thirty years of Ciência & Saúde Coletiva and the insertion of Environmental Health: progress and challenges.

The article takes stock of how Environmental Health is inserted and addressed in the Journal Ciência & Saúde Coletiva (C&SC). Initially, references are made to the editor's words on the 20th anniversary of the Journal on the privileged focus and statistics up to that date. Secondly, it describes some Environmental Health definitions. Then, it presents the results of an analysis performed in all the volumes published in the last ten years based on articles published on the theme yearly. Results indicated variations and even a decline in the percentage of publications dedicated to the field, from 7% to 3%, despite the aggravated environmental crisis on the planet and the call from associations and publications of the health sector that health needs a planetary focus in health policies due to climatic changes and biodiversity loss. The themes in the articles published reveal rich evidence production for current and future actions, in contrast to a poor research agenda still addressed in C&SC.
