Contamination Precautions for Chemicals Which May Be Used in Drinking Water Treatment
ABSTRACT
The present study aims to treat some aspects of environmental contamination under the focus of the principle of precaution, which is based on ideas and discussion about the concerns of society regarding ethics, the environment, water resources, the risk of contamination, and the uncertainties of technological applications in all areas of human knowledge. In the assessment of these scenarios it was decided to evaluate, under a critical view, the chemicals used in the treatment of drinking water, which could cause health problems, directly or indirectly, in the population. Some samples of commercial aluminium sulphate were analysed, concluding that there was a need for physical and chemical assessments to identify the origins of the raw materials used in its manufacturing process.
