The following topics are often considered outdated or at high risk of rejection unless they present innovative methodologies or groundbreaking findings:

1. Basic Heavy Metal Contamination Surveys

-Studies that only report total concentrations of heavy metals in soil, water, or sediments without:

-Advanced source apportionment

-Geochemical modeling

-Novel remediation approaches

-Large-scale or long-term datasets

2. Simple pH, EC, and Basic Soil Property Analyses

Papers that only describe basic soil properties without linking them to:

-Mechanistic geochemical processes

-Environmental risks

-Predictive modeling

3. Redundant Case Studies

Localized contamination assessments already extensively studied in similar settings (e.g., generic mining site pollution studies) lacking:

-Innovative sampling

-New analytical techniques

-Transferable findings
