Hello. I am a physician working on a masters dissertation thesis on the effects of open air defecation on health. There is, unquestionably, an environmental factor here, particularly related to the pollution of water. After years of doing medicine, it is really easy for me to find medical journals, but it seems like I can't find anything published in environmental sciences in peer-reviewed journals. When I google them it seems like everything I find are "regular" websites, and google scholar results are inclined towards showing medical related topics. What are some databases with good environmental journals? Is there something like NCBI but for environment? Thank you
