2022, Environmental ResearchCitation Excerpt :Furthermore, the impact of total organic carbon (TOC) on the accumulation of different organic contaminants in the sediments was also examined from the estuaries. Previous investigations from both the study sites have focussed on metal contamination and OM source characterisation (Harji et al., 2008; Veerasingam et al., 2015a; Ankit et al., 2017; Mishra et al., 2019; Hussain et al., 2020; Bulbul et al., 2021); however no systematic study has been conducted on occurrence and spatial distribution of phthalate esters from both the estuaries. The assessment of pollution status of the estuaries will result in building management strategies as well as monitoring techniques for maintaining the ecosystem health.
Accumulation potential of heavy metals at different growth stages of Pacific white leg shrimp, Penaeus vannamei farmed along the Southeast coast of Peninsular India: A report on ecotoxicology and human health risk assessment
2022, Environmental ResearchCitation Excerpt :According to the Hakanson classification, all the sediment samples are under the low potential ecological risk category (Tables S13 and S8). Hussain et al. (2020) and Sachithanandam et al. (2020) reported low to moderate ecological risk at Astamudi Lake and Andaman Island (South India), which was much higher than that reported in the current study. This could be attributed to the toxic heavy metal concentration in the sediments (Cd, As, and Hg) and their toxic response factor.
Assessment of water quality in a tropical ramsar wetland of southern India in the wake of COVID-19
2021, Remote Sensing Applications: Society and EnvironmentCitation Excerpt :The Kallada river system is a confluence of three small tropical rivers such as the Kulathupuzha, the Chendurni and the Kalthuruthy, originates from Western Ghats. The Asthamudi Lake is permanently connected with the Arabian Sea, and the lake water is exchanged daily by tidal fluctuations (Hussain et al., 2020). The lake is one of the leading centres of marine fish production and landings along the Malabar coast (Thresiamma and Nair, 1980) and receives significant attention due to its rich and varied fishery resources and an annual production of 23000 t of fish (Kurup and Thomas 2001).
