“…Highest percentage of silt and lowest percentage of sand is observed in station 4. The results are comparable with Thangadurai et al 16 and Seshan et al 17 , who reported that the sediments of the Ennore Creek were mostly sandy silt and silty sand.…”

Marine pollution is a major concern of modern times as oceans have become a sink for various industrial effluents and domestic wastewater. Therefore there is a need to study in the physical and chemical behaviour, fate in the environment and potential to cause harm in the long run. The Stockholm convention on persistent organic pollutants is a global treaty aiming to protect human health and the environment from persistent organic pollutants. Persistent organic pollutants are linked to serious health effects in humans and other species including reproductive and developmental illness, immune suppression, nervous systems disorders and cancer and hormone disruption. Every living organism on earth now carries measurable levels of persistent organic pollutant chemicals in its tissues. Because of their particular characteristics, production or use of persistent organic pollutant chemicals anywhere threatens people and the environment everywhere. According to Hurst et al. 1 dioxinlike compounds belong to a class of compounds called polyhalogenated aromatic hydrocarbons and include congeners of polychlorinated dibenzo-p-dioxins, dibenzo-furans (PCDFs) and biphenyls (PCBs). Dioxin-like compounds are ubiquitous in the environment 2 and their presence is primarily the result of by-products of human activities including industrial 3 and other sources (e.g. waste incineration 4). Polycyclic aromatic hydrocarbons are among the most ubiquitous pollutants, with their concentration increasing due to the dependency of human communities to the fossil fuels 5. The present study aims at understanding the dioxin and furan contamination levels and

The present study is focused on determining the acute and chronic toxicity of nickel (Ni) to fish fingerlings, Mugil cephalus. The 96-h median lethal concentration (LC) for Ni was found to be 42.2 ± 3.9 mg L. Based on the chronic toxicity test for 30 days, "No Observed Effect Concentration", "Lowest Observed Effect Concentration" and "Chronic value" were found to be 2.9 ± 0.14, 4.7 ± 0.14 and 3.7 ± 0.14 mg Ni L, respectively. The activities of biomarker enzymes including esterase, superoxide dismutase and malate dehydrogenase showed differential expression and cellular anomalies like hyperplasia and detachment of bipolar cells from photoreceptor cells in the retina of eye of mullet. Cellular anomalies in the retina of fish eye affect the primary function of retina, which is to convert light energy into nerve impulses transferred to the brain via the optic nerve, leading to loss or poor vision.
