“…Negative correlation between dehydrogenase enzyme and heavy metal was also reported by Friedlova (2010). The results get support from the finding of Mikanova (2006) and Victor (2008) It can be concluded that continuous use of sewage irrigation recorded, the amount of microbial biomass C, N and P and soil enzyme activity declined irrigated soils as compared to tube well irrigated soils. Thus, it is justifiable to establish a municipal sewage treatments plant before such sewage water is diverted for the irrigation.…”

“…Although enzymatic activities are substrate specific and do not reflect the overall metabolic activity of soil microorganisms (Nannipieri et al 1997), they are considered to be sensitive indicators of biological activity in soil (Mikanová 2006).…”

“…In our case, dehydrogenases and arylsulphatase activities decreased with increasing extent of contamination (Table 6). Heavy metals inhibit enzymatic reactions by bonding themselves to substrate, creating complexes with substrate, blocking reactive functional groups of enzymes or reacting with an enzyme-substrate complex (Mikanová 2006). Reduced enzymatic activities may also be caused by a lower content of enzymes in the soil.…”

Soil samples were collected at alluvial sites of the Litavka River, which flows through the Beroun and Příbram cities in Central Bohemia Region of the Czech Republic in 2005 and 2006. Higher heavy metal content in soils (Cd, Pb, Zn, Cu) is due to composition of the parent rock, emissions from lead processing industry and the leak of toxic material from the steel works sludge ponds in the 1970s and 1980s. The samples were collected from six sites located at different distances from the contamination source (the former sludge ponds) and chemical and biological properties were determined. The ratio of the microbial biomass carbon to oxidisable carbon content dropped down significantly on more heavily contaminated sites. Basal respiration activity did not correlate with the content of heavy metals in soil, but there was certain declining tendency with increasing intensity of soil contamination. Respiration activities significantly correlated with the total carbon, oxidisable carbon and the total nitrogen content. The metabolic quotient showed higher values with increasing contamination. Dehydrogenases and arylsulphatase activities decreased with increasing contamination. Urease activity has also a declining tendency but its relation to different intensity of contamination was not unambiguous. Urease activity has shown a relationship with the content of total nitrogen in soil. No relationship was found between the total sulphur content and arylsulphatase activity. Dehydrogenases, arylsulfatase and urease activities significantly correlated with the microbial biomass carbon.

“…Generally, soil is able to neutralize the high level elements in it and so prevent aquatic organisms from the toxic effects of these elements. But, there could be heavy metal contamination close to the domestic and industrial waste places, heavy traffic roads and the unconsciously fertilized agricultural areas [9]. Common activities that increase the heavy metal accumulation of soil include the use of heavy metal-containing fertilizers and pesticides in agricultural activities and landscape studies, using high content heavy metal surface waters for irrigation and the use of heavy metal contaminated sew-age sludge and wastes in order to increase the soil productivity.…”

Abstract. Many cities, especially larger metropolises, parks are very important recreational areas where people usually have closer contact with flora. Therefore, the pollution level in the parks can have a greater effect on human health. Heavy metals are ubiquitous with the environment, as a result of both natural and anthropogenic activities, and humans are exposed to them through various pathways. Essentially, these areas are assumed to be less exposed to routine contaminants, but especially in metropolises, this assumption could prove false considering these areas are stuck within the confines of a city full of pollutant activity such as intense traffic. In this study; the relationships between heavy metal pollution levels (Cd, Cr, Cu, Ni, Pb, Zn) and the pH and electrical conductivity (EC) of soil samples were investigated from the parks on the Asian side of Istanbul. For this purpose, the most frequently visited 16 parks were selected as sampling sites. In the second part of the study, linear correlation is used for the data analysis.
