BIOSENSORS FOR THE ENVIRONMENTAL POLLUTION DETECTION AND MONITORING

Abstract

The discharge of dangerous contaminants like pesticides, chemicals and heavy metals into the natural ecosystem is a worldwide issue. Therefore, it is important to identify fast-moving and recyclable contaminants. Biosensors are highly sensitive devices for detecting environmental pollution. Various biosensor types have been developed to detect environmental contamination. Biosensor is the most recent breakthrough in environmental pollution detection and monitoring. Biosensors are widely used in the detection of pesticides, heavy metals, surfactants, biological oxygen demand, phenolic compounds, pharmaceutical compounds, and pathogenic organisms. This paper mainly focuses on the principle, working, characteristics, and uses of biosensors, which are constructed for the detection of pollution.
