The Effects of Organic Enrichment,The discharge of organic matter or nutrients is probably the commonest, the most fully documented and the best understood form of pollution. Indeed, organic enrichment is the classical form of pollution and there is a common tendency to speak of ‘pollution’ when organic enrichment is intended.作者: 燦爛 時(shí)間: 2025-3-26 11:44

This is essentially a ‘bioassay’ of the environmental contamination and, in allowing us to detect the change and, perhaps, estimate its intensity, the indicator has become a ‘bio-sensor’ for that pollutant or stressor.作者: FLAIL 時(shí)間: 2025-3-26 13:38 作者: 即席 時(shí)間: 2025-3-26 18:00
