This study addresses the chemical and toxicological questions due to the wide use of chemical treatment programmes for industrial cooling water. First, natural problems encountered in cooling tower systems were presented and grouped into three categories: (i) scaling; (ii) corrosion and (iii) biofouling. Chemical solutions adopted in industrial plants were outlined for each one in order to minimize damage and categorized as shut-down, production loss, heat transfer reduction, upsets, etc. Above all, the purpose of the work was to identify the most dangerous chemicals normally used, which means sources of chemical risk for safety workers and their environment; thus, symptoms of exposure, prevention measures and protection tools are also described.
由于工业冷却水化学处理方案的广泛应用，本研究探讨了相关化学和毒理学问题。首先，介绍了冷却塔系统中遇到的自然问题，并将其分为三类：（i）结垢；（ii）腐蚀；（iii）生物污垢。针对每一类问题概述了工业工厂采用的化学解决方案，以尽量减少损害，并将其归类为停机、生产损失、传热减少、故障等。最重要的是，这项工作的目的是识别通常使用的最危险化学品，即安全工人及其环境面临的化学风险来源；因此，还描述了接触症状、预防措施和防护工具。
