Assessing the Environmental Safety of Corrosion Inhibitors in Iraqi Studies: A Predictive Analysis

Abstract

Corrosion inhibitors play a crucial role in mitigating the detrimental effects of chemical and electrochemical interactions over time. This phenomenon poses significant threats to structural integrity, strength, and has far-reaching economic implications across various industries such as construction, petrochemicals, mining, fertilizer, and energy units. The environmental repercussions, including toxic outflows and plant failures, underscore the need for comprehensive assessments. Despite the commendable contributions of Iraqi researchers in developing organic, inorganic, natural, and nano-corrosion inhibitors, there is a critical gap in considering potential side effects. This study explores a pioneering approach to evaluating the toxicity of corrosion inhibitors on both human health and the environment. Leveraging mathematical modeling and mechanisms, we present a mimic estimation of environmental factors influencing corrosion phenomena. The out-lab experimental calculations employ Quantitative Structure-Activity Relationship (QSAR) techniques, providing a structural-based predictive model for assessing the potential impact of chemicals before embarking on experimental complexities. Drawing from Iraqi journals, seven corrosion inhibitors with diverse chemical structures, experimental conditions, and publishing sources were selected. These compounds were subjected to scrutiny using online prediction websites that evaluate Embro-toxicity, Cardio-toxicity, and crop-toxicity. Each inhibitor underwent screening by specific toxicological web servers. The findings revealed that all studied compounds posed moderate to extremely unsafe risks to fetal health during pregnancy, potentially categorizing them as teratogens with elevated risks of preterm labor, miscarriage, or stillbirth. Additionally, none of the tested materials exhibited herbicidal activity.
