Study on the physico-chemical properties of water in the Pokkali wetlands of Ernakulam, Kerala, India

Abstract The Pokkali wetlands of Ernakulam District, Kerala, are incredibly nutrient-rich, biodiverse habitats that offer a wide range of benefits. There are important bird areas that lie under the Central Asian Flyway (CAF) and the Vembanad Ramsar site. An intensive study was carried out on the physico-chemical properties of water samples collected from the Pokkali wetlands of Ernakulam, Kerala, from 1 June 2016 to 31 May 2019. The water parameters, such as temperature (°C), pH, depth (cm), dissolved oxygen (DO) (mg/L), salinity (mg/L), turbidity (NTU), and electrical conductivity (μS cm−1) were analysed and recorded. The correlation between various parameters was analysed using the PAST software. The physico-chemical parameters of water have an influence on the biodiversity and ecology of the study area. Data collection about these aquatic parameters is essential to assess the status and biodiversity of the wetland ecosystem.
