“…The sediments have been dated by Cs ~37 and Pb 2~" (Johnston, 1980). Sediment was placed in solution by the method of Buckley and Cranston (1971). Chemical analyses were performed by flame atomic absorption spectrophotometry (TiO 2, CaO, MnO, FeO, and Zn) and by graphite furnace atomic absorption spectrophotometry for Pb.…”

Abstract. Empirical field evidence for changing chemical processes in soils caused by atmospheric deposition of pollutants consists of: (1) Long-term water quality data including total dissolved solids, concentrations of specific metals (e.g. Ca), and conductivity; (2) Cation exchange capacity and base saturation values for soils located on precipitation pH gradients; (3) Lysimeter studies; and (4) Chemical analysis of organic soils on precipitation pH and metal gradients. For well-drained organic soils, as precipitation pH decreases, metals are differentially leached at an accelerated rate (Mn > Ca > Mg >--Zn > Cd and Na > AI). Experimental field and laboratory lysimeter studies on soil columns yield similar results, with increases in leaching rates for soil solutions with pH = 3 up to 100 x values for soil solutions with pH = 5. Nearly 100% of the Pb from precipitation is accumulating in the organic soil layer or sediments. Zn is accumulating in soils and sediments where the pH's of precipitation, soil solutions, and surface waters are generally above 5 to 5.5. At lower pH values Zn and other chemically similar elements are desorbed/leached (net) at an accelerated rate.Chemical analyses of dated sediment cores from high and low altitude lakes, with drainage basins relatively undisturbed for the last 200 + yr, reveal that increased deposition of metals on a regional scale started in the northeastern United States as early as 1880, consistent with increased fossil fuel consumption. This suggests acidified precipitation as early as 1880. Cores from historically acidified lakes (pH < ~ 5.3 to 5.5) indicate that, as acidification of surface waters occurs (caused by acidic deposition), concentrations of Zn, Mn, and Ca decrease in the sediment. Apparently the metals are leached from the detritus prior to sedimentation. This conclusion results from data from experimental acidification of sediment cores and the general observation that precipitation pH is generally >--0.5 pH units lower than lake water pH. Accelerated leaching of soil in New England dates to earlier than 1900.

“…Because of the possibility of trace element loss due to volatilization at higher temperatures (Buckley and Cranston, 1971 ), all processing steps were done at temperatures below 120 degrees (C) and, when possible, in a closed system. The procedure involved the transfer of the particulate fraction from a centrifuge tube or filter split to a Parr Co. model 4745 acid digestion bomb with long-taper sealed teflon cups.…”

“…The mixture was refluxed with 10 ml of 37% HCl at 95 °C for 15 minutes [9]. The dig estate obtained was filtered through a 0.45 μm membrane paper, diluted to 100 ml with deionized water and stored at 40C for analyses [82,44]. All the digested soil samples were analyzed for concentration of chromium (VI), lead, copper, cadmium, iron, cobalt, magnesium, manganese, calcium, nickel, zinc, aluminium (Respective metal wave length calibration in nm) by using Atomic Absorption Spectrometer (VARIAN AA240, Austria) [83].…”

From the dawn of industrial revolution there has been a ceaseless development of technologies to support human comfort. These technologies besides leading to a better living, also causes hazardous effect to the society when not treated properly. One of the major developments in the industrial era is refining of leather. The heavy metals when released from these industries contaminate the surrounding. The study aims at getting more clear understanding about the contamination of the heavy metals in the water and soil samples which cause skin allergy risks for industry workers and habitants residing near the tannery zone .The research intents at reckoning the heavy metal contamination in 20 bore well water ,20 soil samples and 20 tannery workers (10 male and 10 Females) blood samples who were suffering from skin allergy taken from the zone in and around leather tanneries in Vellore district. The samples were tested by various methods to estimate approximate value of large number of heavy metals including Cu, Al, Zn, Cr, and Ni. Besides; various physical characteristics of the water were also tested. The comparison against the permissible standard was made and the results showed excessive deposition of toxic metals in the samples. Moreover, the blood samples of people around these areas where also tested for heavy metal contamination and surveyed number of people admitted in ESI hospital with skin allergy from year of 2014 to 2016 in the study area. These numbers showed a continuous hike when compared with the value evaluated in the earlier days.
