This study chooses the industrial wasteland after the relocation of a metal processing factory in Shenyang, Liaoning Province of China as the research object. Based on level three soil heavy metal quality standards of Soil Environment Quality Standard (GB15618-1995) in China, the pollution levels of four heavy metals (cadmium, lead, copper and zinc) in survey area are Cd> Cu> Zn> Pb; the Cd pollution is the most serious one, followed by Cu and Zn. The Pb content is low. Average comprehensive pollution index of Cd, Cu, Zn and Pb in soil of the wasteland is 17.33, which belong to Grade V severe pollution. The most polluted point is J-12, followed by J-11 and J-16. The land utilization risk assessment of the wasteland should be strengthened, and appropriate and necessary repair measures should be taken, such as planting accumulative or tolerant plants.

An integrated pollution assessment index approach was used to assess the application of heavy metal pollution indices in the Ngoua watershed in southwestern (SW) Cameroon. The concentrations of Pb, Cr, Cu, Ni, Zn, Mo, Fe and Al in most of the water samples exceeded the maximum allowable concentration recommended by the World Health Organization (WHO). The Heavy Metal Evaluation Index (HEI) shows strong correlations with the Heavy Metal Pollution Index (HPI), Metal Index (MI) and the degree of contamination (Cd), and gives a better assessment of the pollution levels. Selected samples from the 10 sampling stations were classified as high polluted in Cd, MI and HPI in relation to the respective critical values. These values show comparable results to those of the HEI and indicate that about 88% of the samples with above average values were classified as highly contaminated and the remaining samples (12%) with below average values were classified as moderately contaminated. The Enrichment Factor (EF) analysis and the pollution indices reveal that the water quality is mainly controlled by natural and geogenic processes with major anthropogenic input. The current level of heavy metal distribution in the water of the Ngoua catchment is an environmental and health concern and requires special attention.

This paper took the SongSan wastewater irrigation district of Liaoning Province, Anshan city as object of study. Base on the survey on the sewage irrigation situation, heavy metal concentration in rice grain and drinking water were measured through single pollution index evaluation and comprehensive pollution index evaluation (Nemerow index method). It could be served as the basis for environmental management and relevant laws and regulations. Experimental results showed that drinking water were not polluted by heavy mental. Sewage irrigation had a comparatively small impact on drinking water. According to the heavy mental determination results of grain crop seeds, it can conclude that the Cu and Pb content were above the national food quality standard. The pollution is serious, however, the content of Zn and Cd were below or close to the national food quality standard, which is in danger of exceeding the standard. Determined by comprehensive pollution index, it showed that the rice in the whole sewage irrigation is serious polluted by heavy mental. The heavy metal pollution presented the characteristics of extensive area-source pollution. Pollution intensity was strengthened and more difficult to be managed.

A survey and comprehensive assessment were conducted to investigate Cd, Cu, Ni, Pb, and Zn concentrations in 67 greenhouse leafy vegetables and the corresponding topsoil from the typical greenhouse vegetable cultivation area in southeastern China. The Cd concentrations in all soils exceeded the Chinese standard GB15618-1995, Cu, Ni, and Zn concentrations were slightly elevated, while the soils were not polluted by Pb. The single-factor pollution index showed that Cd in the soils reached “moderate pollution” levels and other metals were present at safe levels. The Nemerow integrated pollution index was more appropriate than the single-factor pollution index for assessing heavy metal pollution in the soils, and the results showed that Cd was the main pollutant in the studied region, especially in Chun’an, Fuyang, Lin’an, and Tonglu districts. All of the greenhouse vegetables analyzed were heavily polluted by Cd and Pb, moderately polluted by Ni and Zn, but not polluted by Cu. The Cd, Pb, and Ni concentrations in the vegetables exceeded standard GB2762-2005. The bioconcentration factors for the vegetables analyzed decreased in the order Cd>Zn>Cu>Pb>Ni. Lettuce (Spinacia oleracea) accumulated Cd more strongly than the other leafy vegetables analyzed, and tarragon (C. coronarium) accumulated Cu and Zn most strongly.

Abstract Upper Cretaceous sedimentary rocks are widely exposed around Trabzon, Giresun and Gümüşhane in the eastern Pontides. The sedimentary rocks are mainly composed of sandstones and marls, and the thicknesses of these rocks range from 170 m to 400 m. This paper focused on Late Cretaceous sandstones of Trabzon, Giresun and Gümüşhane regions to identify the concentrations, sources, deposition environment and conditions of certain heavy metal(loid)s (Zn, Pb, Cu, Ni, As, Co, Mo and V). Enrichment factor (EF), geo-accumulation index (Igeo), Pollution index (Pi), Pollution load index (Pln), Pb isotope and multivariate statistical analysis were performed to elucidate the pollution levels and sources. The mean concentrations of Zn, Pb, Cu, Ni, As, Co, Mo and V were 16.5, 10.8, 9.4, 13.2, 2.1, 4.4, 0.2 and 21 mg/kg, respectively in the Trabzon area, 35, 5.8,18.8, 102, 3.2, 18.6, 0.5 and 109 mg/kg, respectively in the Giresun area, and 36, 8.9, 14.7, 82, 3.9, 16.9, 0.3 and 106 mg/kg, respectively in the Gümüşhane area. In general, the evaluation indices exhibited that the sandstones were moderately polluted by As in the Trabzon area, and strongly polluted by Ni and As, moderately polluted by Co and V in the Giresun and Gümüşhane areas. The results of multivariate statistical analyses indicated that As and partly Pb might be originated from anthropogenic sources, whereas other metals were derived from geogenic origin. Lead isotopic analysis demonstrated two characterized signatures of the pollution sources in the sandstones, one related to geogenic origin and the other to coal, gasoline and pesticides. The sandstones were deposited in transition – marine environment under oxic – weak oxic conditions and paleoclimatic conditions ranged from arid to moist during Late Cretaceous period.

To understand the environmental quality and heavy metal(loid) pollution of farmlands in Shangdan Valley, the contents of macroelements (Na, K, Si, Mg, Ca, Al, Fe, Ti, P, S, Cl, Br) and heavy metal(loid)s (Cu, Pb, Zn, Mn, Ni, V, Co, Cr, As) were surveyed by the X-ray fluorescence method. The pollution degree and ecological risk of the heavy metal(loid)s were judged by the Nemerow synthetic pollution index, geo-accumulation index, and potential ecological risk index, and their sources were identified by the multivariate statistic method. The mean contents of nine heavy metal(loid)s in Shangdan Valley farmland soil exceeded their corresponding reference values. Soils were not contaminated with As, Cr, Mn, and Ni but were slightly contaminated with Co, Cu, Pb, V, and Zn. Their comprehensive pollution levels were moderate to serious. The ecological risk index of single heavy metal(loid) decreased in the sequence As > Pb > Co > Cu > Ni > V > Zn > Cr > Mn. The source analysis results indicated that Cu, Pb, Zn, and As were highly affected by anthropogenic inputs, e.g., metal smelting and agricultural activities, while Mn, Ni, Cr, and V were principally derived from a natural source. As for Co, it was affected by a mixture source of nature, fossil fuel combustion, and fertilizer.

Penelitian ini bertujuan untuk mengetahui  pencemaran kadar Nitrat (N) dan Posfat (P) di Beberapa Sub DAS Kalimantan Selatan berdasarkan metode Indek Pencemaran (Kep_MENLH/115/2003).Dari hasil penelitian diperoleh hubungan (r) antara variabel Baku Mutu (Y1) dan variabel (X) atau Posfat dan Nitrat  = 0,792. Perhitungan terhadap nilai R2-determinant diperoleh hasil sebesar 0,672. Hal ini berarti 67,2 % faktor Baku Mutu Air (Y) dipengaruhi oleh faktor Posfat dan Nitrat, sisanya sebesar 33,8 % dipengaruhi oleh variabel lain yang tidak dapat dijelaskan dalam persamaan. Rasio antara parameter P dan N (P = 0,577 : N = 0,062 = 9,30),  berada diantara 7 sampai 12.  Berarti variabel Posfat dan Nitrat bukanlah sebagai faktor pembatas terjadinya pencemaran. Hasil Perhitungan indeks pencemaran terhadap pareameter P dan N diperoleh nilai sebesar 9,30, masih memenuhi baku mutu untuk beberapa Sub-sub DAS (Riam Kanan, Tabanio, Sungai Naiyan, Sungai Satui, Sungai Kintap, Sebamban dan Sungai Kusan).This study aims to determine the pollution levels of nitrate (N) and phosphate (P) in South Kalimantan Several subzone based method Pollution Index (Kep_MENLH / 115/2003).The results were obtained relationship (r) between the variables Quality Standards (Y1) and variable (X) or Phosphate and Nitrate = 0.792. Calculation of the value of R2-determinant obtained yield was 0.672. This means that 67.2% factor Water Quality Standard (Y) is influenced by factors Phosphate and Nitrate, while the remaining 33.8% is influenced by other variables that can not be explained in the equation. The ratio between the parameter P and N (P = 0.577 N = 0,062 = 9.30), is between 7 to 12. It means that the variable Phosphate and Nitrate is not a limiting factor for contamination. Calculation results of the pollution index pareameter P and N obtained a value of 9.30, still meet quality standards for some sub-sub-basins (Riam Kanan, Tabanio, Naiyan River, River Satui, Kintap River, and the River Sebamban Kusan).

The article focuses on the study of change of containing heavy metals (zinc, copper, iron, cadmium, lead, arsenic) in the abiotic and biotic components of the Serepok river (Vietman) influenced by wastewater discharge from industrial areas. Heavy metal content was determined in the river water and bottom sediments in the four zones: above and within the boundaries of industrial regions Xoa Phu and Tam Thang and in two water reservoirs situated below the boundaries of those industrial areas. Tilapia Galilean ( Sarotherodon galilaeus ), Hemibagrus ( Hemibagrus ), and sazan ( Cyprinus carpio ) caught in these areas were the hydrobionts under study in which liver, gills, skeleton and muscles accumulation of heavy metals was detected. In the organs of fish caught in the river within industrial region, heavy metals concentration was 3-7 times higher. The greatest concentration of heavy metals was found in the liver and gills of fish caught in the boundaries of industrial regions, the least concentration was in the muscles. In most cases, significant correlation between heavy metal concentration in organs of fishes and in river water, bottom sediments has been revealed.

This study attempted to analyze the distribution and contamination status of heavy metals (Cu, Fe and Zn) along western coast of Bali Strait in Banyuwangi, East Java. Bali Strait is one of the many straits in Indonesia with high fisheries activities that could potentially contributed to high heavy metal pollution. There were five sampling areas from the north to south: Pantai Watu Dodol, Pantai Kalipuro, Ketapang Port, Pantai Boom and Muncar as the fish landing area. Heavy metal pollution in these locations comes from many different activities such as tourism, fish capture and fish industry and also domestic activities. Contamination factor (CF), geo-accumulation index (Igeo) and enrichment factor (EF) of each heavy metal were calculated to obtain contamination status of the research area. The concentrations of Fe were observed the highest (1.5-129.9 mg/kg) followed by Zn (13.2-23.5 mg/kg) and Cu (2.2-7.8 mg/kg). The distribution of Cu, Fe and Zn showed variability among the sampling locations in which high concentrations of Cu and Zn were higher in Ketapang Port, whereas high concentration of Fe was high in almost all sampling locations. According to the pollution index, contamination factors of Cu, Fe and Zn were low (CF < 1 and Igeo < 1). However, high index of EF (> 50) showed high influence of the anthropogenic activities to the contribution of the metals to the environment. This could also because of the high background value used in the calculation of the index due to the difficulties in finding background value from the sampling areas.Keywords: heavy metals, pollution index, contamination factor, geo-accumulation index, Bali Strait

AbstractIn this study, the release of Cu2+ and Zn2+ was investigated and modeled in the epiphytic lichen Evernia prunastri. Samples were incubated with solutions containing these metals at ecologically relevant concentrations (10 and 100 μM) and then transplanted to a remote area and retrieved after 1, 2, 3, 6, 12, and 18 months. The results showed that, after 12 months, all samples faced similar metal reductions of ca. 80–85%, but after this period, all the involved processes seem to be no longer capable of generating further reductions. These results suggest that the lichen E. prunastri can provide information about environmental improvements after exposure to high or very high pollution levels in a relatively short period of time.
