“…The study area was divided into grid cells of 1 km×1 km for sampling so as to reduce the random influence from urban wastes (Rizo et al 2011). A total of 467 topsoil samples (0~20-cm depth) were collected inside these grid cells in different functional zones (Fig.…”

Surface soil samples from 467 sample sites were collected in urban area of Wuhan City in 2013, and total concentrations of five trace metals (Pb, Zn, Cu, Cr, and Cd) were measured. Multivariate and geostatistical analyses showed that concentrations of Pb, Zn, and Cu are higher along Yangtze River in the northern area of Wuhan, gradually decrease from city center to suburbs, and are mainly controlled by anthropogenic activities, while those of Cr and Cd are relatively spatially homogenous and mainly controlled by soil parent materials. Pb, Zn, Cu, and Cd have generally higher concentrations in roadsides, industrial areas, and residential areas than in school areas, greenbelts, and agricultural areas. Areas with higher road and population densities and longer urban construction history usually have higher trace metal concentrations. According to estimated results of the potential ecological risk index and Nemero synthesis pollution index, almost the whole urban area of Wuhan is facing considerable potential ecological risk caused by soil trace metals. These results reveal obvious trends of trace metal pollution, and an important impact of anthropogenic activities on the accumulation of trace metals in soil in Wuhan. Vehicular emission, industrial activities, and household wastes may be the three main sources for trace metal accumulation. Increasing vegetation cover may reduce this threat. It should be pointed out that Cd, which is strongly accumulated in soil, could be the largest soil pollution factor in Wuhan. Effective measures should be taken as soon as possible to deal with Cd enrichment, and other trace metals in soil should also be reduced, so as to protect human health in this important large city.

“…General source are mining and industrial wastes, vehicle emissions, lead-acid batteries, fertilizers, paints, treated woods, plastics floating in rivers and drains [20,34]. Cobalt can accumulate to toxic levels in the liver, kidney, pancreas, and heart, as well as the skeleton and skeletal muscles [6].…”

Due to rapid urbanization and industrialization in many countries of the world, heavy metals are continuously emitted into the terrestrial environment and posing great threat to human health. The present study was conducted to measure the concentration of six heavy metals, chromium (Cr), nickel (Ni), cobalt (Co), zinc (Zn), cadmium (Cd) and lead (Pb) in roadside dust of five major roads in Gujrat city. The dust samples were collected from five different locations in the vicinity of Gujrat. The results showed that the average concentrations of Cr, Ni, Co, Zn, Cd, and Pb in the dust samples were higher than their permissible limits. The concentrations of Cu, Zn, Cd and Pb were much higher than those in the background value of Gujrat soil. Results clearly concluded that the heavy traffic and transportation is the major responsible source of these heavy metals in the road dust of Gujrat city along with the transportation of sewage sludge, surface runoff from agricultural land and discharge of sewage water from drains.

“…Rapid population growth, excessive urbanization, industrialization, and increasing use of natural resources led to environmental problems in Turkey, as well as the rest of the world [1,2]. Heavy metal pollution is one of the primary problems which must be resolved in both terrestrial and aquatic environments.…”

A B S T R A C TIn this study, the water quality and heavy metal pollution status of Riva Stream which is related to Ö merli Dam Lake, one of the water resources of Istanbul (Turkey), was determined. For this purpose, some physicochemical parameters, phytoplankton compositions, some nutrient, and heavy metal concentrations in the surface water of Riva Stream were investigated. Samples were collected at six sampling sites in the course of the stream in February 2012 and May 2012. A total of 19 taxa, belonging to five divisions, were identified. The phytoplankton density varied from 47 to 264 ind./cm 3 ; chlorophyll-a contents varied between 1.52 and 1.83 mg/m 3 . Measured concentrations of heavy metals and nutrients showed difference related to sampling points. As a result of measurements, the lowest and highest heavy metal and mineral nutrient concentrations of measured water samples were as follows: Al (617.40-1094.16 μg/L), B (1010.40-5736.00 μg/L), Ca (1015.80-1925.40 mg/L), Cd (1.45-5.22 μg/L), Cr (61.26-164.16 μg/L), Cu (35.04-372.66 μg/L), Fe (28.50-369.06 μg/L), K (179.10-1314.60 mg/L), Mg (202.68-1755.60 mg/L), Na (669.00-1553.40 mg/L), Ni (40.62-269.70 μg/L), Pb (6.48-76.86 μg/L), and Zn (429.18-990.60 μg/L).It was observed that Riva Stream is highly polluted by some heavy metals, and a number of heavy metal resistant/tolerant phytoplankton species are present in the stream. Pearson's correlation and Spearman rank correlation analyses were applied to examine the relationship between Al, B,
