Passive sampling techniques in environmental monitoring

摘要: Monitoring pollutants in air, soil and water is a routine requirement the workplace, wider environment. Passive samplers can provide representative picture of levels over period time from days to months by measuring average concentrations which they have been exposed. Air monitors are widely used, for instance measure exposure workers volatile compounds, but also monitoring fate atmosphere. sampling devices now becomining increasingly used monitor rivers, coastal waters ground where contamination results sources such as domestic industrial discharges, use agrochemicals.
