“…Cu levels in the present study are below the maximum permissible limit (30 μg g −1 ) of WHO 1989 and Nauen 1983. Its content reported in the literature is in the range of 0.12-0.31 μg g −1 in fish species from Parangipettai (Raja et al 2009) and 20.48 μg g −1 from Poompuhar Coast, southeast coast of India (Prasath and Khan 2008). The present values are significantly lower than that of Poompuhar Coast, however, marginally higher than that of Parangipettai Coast.…”

Concentrations of Cu, Mn, Zn, Fe, Cr, and Pb were estimated using ICP-MS in nine commercially important and locally consumed fish species (Sarda orientalis, Scomberomorus commerson, Rastrelliger kanagurta, Sardinella longiceps, Paraplagusia bilineata, Cynoglossus lida, Cynoglossus macrostomus, Lepturacanthus savala, and Siganus javus) collected from coastal waters of Kalpakkam, eastern part of India. Their concentration (μg g(-1)) in the examined fish species ranged as follows: Cu (0.8-6.5), Zn (14.3-27.9), Mn (0.5-8.8), Fe (17.6-117.0), Cr (0.24-1.78), and Pb (0.18-2.29). Concentrations of most of the metals in the fish species studied were found to be safe for human consumption barring Mn.

“…It is worth mentioning here that the clay contents (\0.2%) observed during the present study (post-tsunami period) are significantly lower than the pre-tsunami period (4%) pointing that the top surface layer containing a relatively high amount of silt and clay has been transported from coastal bed to the adjoining land. Prasath and Khan (2008) have also reported similar trends during post-tsunami for Fe.…”

Studies on the variations of heavy metals in the marine sediments off Kalpakkam, East Coast of India

During the last two decades, the coastal environment of southeast India has experienced intense developments in industry, urbanization and aquaculture. Moreover, the 2004 mega tsunami has devastated this coast, thus affecting the coastal sediment characteristics. These two phenomena prompted a study to characterize the sediment, to understand the mechanisms influencing the distribution of heavy metals and to create baseline data for future impact assessment. Results showed that the coastal sediment was carpeted with a mosaic of sand and silty sand with a minor amount of clay. Heavy metal values showed maximum variation for Fe and minimum for Cd. Their average values showed the following decreasing trend:This study shows that the major source of metals at Kalpakkam coast are land-based anthropogenic ones, such as, discharge from industrial waste, agricultural waste, urban, municipal and slum sewage into the Buckingham canal, which in turn discharges into the sea through backwaters, particularly during northeast monsoon period. A clear signature of the role of backwater discharge increasing the concentration of a few metals in the coastal sediments during monsoon period was observed. Assessments of the degree of pollution, concentration factor (CF), geoaccumulation index (I geo ) and pollution load index (PLI) have been calculated. CF values and I geo indicated that the coastal sediment is moderately polluted by Cu and Cd. Increase in Cu, Pb and Zn concentration during the monsoon period (October-January) compared to the rest of the year was noticed. Factor analysis and correlation among the heavy metals concluded that Cr, Ni, Cd and Fe are of crustal origin, whereas, Cu, Pb and Zn are from anthropogenic sources. Organic carbon content in the sediment increased during monsoon period, pointing to the role of land runoff and backwater discharge in enhancing its content. The study also elucidates the impact of the recent tsunami in depleting metal content in the coastal sediment as compared to the pre-tsunami period.

“…Two studies had a strong statistical experimental design; one used a BACI design (Before After Control Impact) to examine the success of land use restoration on decreasing heavy metal concentrations in the tissue of M. cephalus (Huang et al 2008). The second study inspected changes in fish tissue heavy metals collected before and after a tsunami (Prasath and Khan, 2008).…”

Use of flathead mullet (Mugil cephalus) in coastal biomonitor studies: Review and recommendations for future studies

There has been a widespread world-wide use of flathead mullet, Mugilcephalus, in fish biomonitor studies within the coastal zone. This review summarises this research field, focusing on heavy metals, and considers the implications of the accumulated data. Differences in sampling methodology, tissues analysed and units of reported data provide challenges in assessing and benchmarking these biomonitor studies. The benthic feeding strategy of M.cephalus invariably increases exposure risk relative to middle or upper water column feeders, nevertheless contaminant accumulation via direct and indirect pathways was regulated sufficiently such that toxicants were below food guidelines in most coastal regions (32 of the 49 examined). Human health issues can arise if fish are consumed from heavily industrialised regions. Recommendations are provided for future biomonitoring studies, based on the results for M. cephalus but relevant for fish species more broadly, to provide more comparable data so that managers can benchmark against local conditions.
