Assessment of Physico-chemical Characteristics of Mangrove Region in the Krishnapatnam Coast, India

Biogeochemistry of the dissolved organic matter (DOM) in the estuarine rivers of Bangladesh–Sundarbans under different anthropogenic influences

“…Electrical conductivity (EC) ranged from 3.5 mS/cm at Mongla Port to 36.1 mS/cm at Dublar Char (mean = 20.6 mS/cm, σ = 14.0) ( Table 2 ). EC in this study was higher than the Sibuti mangrove forest (0.8–96.1 μS/cm) at Miri Sarawak of Malaysia ( Gandaseca et al., 2015 ), but comparable to the mangrove region (32.8–51.6 mS/cm) in the Krishnapatnam Coast of India ( Dattatreya et al., 2018 ). TDS varied from 1805.5 mg/L at starting point Mongla Port to 18025.0 mg/L at the Dublar Char (mean = 10473.3, σ = 7079.5) ( Table 2 ).…”

Spatial and temporal variations in physico-chemical characteristics of water in Gangavali and Aghanashini mangroves, Southwest coast, Karnataka

“…Priya et al (2019) [31] conducted research on the physico-chemical attributes of the Kodiakkarai coast and mangrove in Nagapattinam district, Tamil Nadu, India and recorded the nitrate levels ranging from 0.44 to 0.57 mg/l with the lowest during the summer and highest during the monsoon season. (2020) [29,12,22,3,14,9] made similar observations. Ravaniah et al (2010) [33] stated that the impact of seasonal rainfall may be responsible for the highest concentration of nitrate during the rainy season, while the low value during the summer months may be brought on by limited freshwater influx and more salinity.…”

“…The maximum was recorded in the month of March while the minimum was reported during the month of August in Gangavali mangrove. The existence of residential waste and the lack of regular tidal action, which would have had a flushing and diluting effect on dissolved components as well as bicarbonates, could have influenced the higher total alkalinity values found in summer regardless of the season (Dattatreya et al, 2018) [14] . The hardness of water in the present study ranged between 468-11800 mg/l.…”

“…Due to instability, physico-chemical properties are crucial to water quality criteria to monitor since they have a substantial impact on the quality of water resources (Vaghela et al, 2010) [43] . Several studies on physiciochemical parameters have been carried by many researchers on Indian mangroves (Prabu et al, 2008 [29,37,21,4,10,20,3,7,30,14,9] . The present work aim to study the seasonal and spatial variations in water quality and nutrient dynamics in Gangavali and Aghanashini mangroves, Southwest coast, Karnataka to create baseline data for the policy makers that would be valuable from the management point of view.…”

Frequency-Dependent Magnetic Susceptibility and Chemical Composition of Estuary Mangrove Sediment as Environmental Indicator of Ecosystem Degradation

“…Nonetheless, some studies have reported that mangrove forests in various parts of the world have degraded because of increased urbanization, which has resulted in increased anthropogenic activity in mangrove areas (Buajan and Pumijumnong, 2010; Defew, Mair, and Guzman, 2005). Many studies have been conducted on the physical-chemical properties of sediments and water quality in the mangrove environment, such as pH, salinity, biochemical oxygen demand (BOD), chemical oxygen demand (COD), and total phosphorus (TP) (Arumugam and Kumar, 2014; Arumugam and Gomathinayagam, 2015; Dattatreya et al ., 2018; Kurlapkar and Shaikh, 2014; Saseeswari, Kanimozhi, and Paneerselvam, 2015; Thirumurugan and Vijayakumar, 2016).…”
