**Conflict of interest**

There is no conflict of interest issue with the coauthors in my previous publication on Lead Contamination in Zamfara State, Nigeria. That article titled, Environmental Effect of Lead Contamination on Mining Communities in Zamfara State, Nigeria - A Review, was a collaborative paper that I authored and invited them for additional inputs, suggestions and criticisms. We did it amicably in the year 2020 during the COVID-19 pandemic, when we were both less busy. The coauthors of that article are currently busy with their individual pursuits in their chosen areas of engagement. I hereby assure the audience that my relationship with each one of them is cordial and we both wish each other well. I very much appreciate each one of them for their complement to me on this project.
