“…These variations in the marine environment are certainly brought about by the recent tsunami as similar type of variations in the physico chemical characters were observed in the coastal water quality off Nagapattinam coasts 15 . Many of the earlier works revealed that heavy metals were more concentrated in the tissues of marine animals than in seawater due to bio magnification [16][17][18] . The same trend was observed in the present study also.…”

Investigations on the accumulation of heavy metals (Zn, Cu, Fe, Mn, Co, Pb, Cd and Ni) in water, sediments and fish (Mugil cephalus) using Atomic Absorption Spectrophotometer at Poompuhar coast, lying along the southeast coast of India was studied before and after tsunami. Accumulation of heavy metals was observed in the order of Sediments > Fish > Water. In water, the order was found to be Mn > Fe > Zn > Cu > Ni > Cd > Co > Pb; Mn recorded a maximum of 506.9µ. L-1and Pb recorded a minimum of 0.006µ. L-1. In sediments, the order was Mn > Fe > Cu > Zn > Pb ≈Co ≈Cd ≈ Ni; Mn recorded a maximum of 851.1µg.g-1and a minimum of below detectable levels were found in Pb, Co, Cd and Ni. In fish, the order was found to be Fe > Zn > Mn > Cu > Ni > Co ≈ Pb ≈ Cd; Fe recorded a maximum of 529.13 µg. g-1and a minimum of below detectable levels were found in Pb and Cd.

“…Heavy metals such as lead and mercury are removed from waters very quickly after they enter the marine environment from sewer outfalls or rivers and associate with the sediments within several kilometers of the input site to the marine environment (10). Hence, only a fraction of the waste, storm, and river runoff would be expected to reach the basins.…”

The present anthropogenic lead fluxes into sediments from the Santa Monica, San Pedro, and Santa Barbara basins of Southern California are, respectively, 0.9, 1.7, and 2.1 micrograms of lead per square centimeter of sea bottom per year; the natural (prepollution) rates for these three basins were, respectively, 0.24, 0.26, and 1.0 microgram of lead per square centimeter per year. Studies of isotopic composition indicate that lead pollutants in coastal sediments are derived mainly from the combustion of lead additives in gasoline.

a Van Dorn sampler were made at two depths, 5 m and 16 m. Two or three dissolved gas sampling bottles were filled with water from each of the casts with the Van Dorn sampler. The dissolved gas concentrations in each sampling bottle were determined three or four times. These data, therefore, indicate a measure of the variability encountered in analysis of one sample bottle and from taking separate samples at a particular depth. The range of values was greater for separate samples from one depth than for several measurements from one sample bottle. With one exception, the mean values for both nitrogen and methane concentrations from all sample bottles from a given depth were judged to be statistically equivalent at the 95% confidence level according to the t test (Huntsberger, 1961). The exception, the nitrogen concentrations for Van Dorn cast number one, was higher than those of casts numbers two and three. The variations in dissolved methane concentrations were slightly greater than those in the nitrogen determinations. In all cases, however, the precision of the analyses was within ±7% of the average and generally within ±5%. ConclusionsThe data gathered by this study indicate that collection and storage of water samples in the dissolved gas sampling bottles is a method that maintains dissolved nitrogen and methane concentrations constant during storage. The overall method of collection, filling, storing, and analyzing is precise to within ±7% or less. The sampling bottles offer a convenient means of filling and transferring the water sample to the gas stripping chamber. When this method of sample collection and storage is used, the largest source of analytical error for this study was apparently the instrumentation. Literature CitedHuntsberger, D.
