Lakes and wetlands constitute a major portion of the total surface fresh water. In Tirupur, the industrialisation of the town and increase in the population, the river Noyyal and nearby wetlands face serious threat of pollution. As the wetland comes under the city corporation limit, a large human settlement is seen living in its banks and hence the wetland and river gets polluted and the quality of water gets considerably deteriorated. The objective of this study is to investigate the metal content in both biotic and abiotic component of Andipalayam lake and the Noyyal river at Tirupur, Tamilnadu. The samples were collected and analysed for metals like copper, zinc, iron and Manganese. The observation of the study reveals that the metal content of water and sediment at river Noyyal and Andipalayam lake was considerably higher. The accumulation in plankton and in tissues of various fishes (common Carp, Claris baitrachus, Tilapia, Macronis keteius etc) was also high.
