Improved acidity estimation by integrating comprehensive dissolved metal(oid)s ...
Barroso, Ana Raquel; Cravotta III, Charles A.; Gomes, Patrícia; Antunes, Isabel Margarida Horta Ribeiro; Marinho Reis, A. PaulaThis study introduces a geochemical modeling approach using PHREEQC to improve the accuracy of acidity estimates in waters influenced by acid mine drainage (AMD). AMD, common in regions like the Iberian Pyrite Belt, is characterized by low pH and high concentrations of metals, sulfate and acidity. Conventional methods, such as net acidity, often underestimate actual acidity by excluding additional metal(oid) s ...
