“…Soil pH is one of the very important factors that are considered to evaluate the effect of pollutants on the activity of soil microorganisms, however, it is very difficult to separate the effect of heavy metal stress on soil microbial populations from that due to pH changes (García-Gil et al, 2013). Changing soil pH to an acidic level due to the soil management effect may intensify the heavy metal effect further (Wyszkowska et al, 2016). The decreasing pH leads to the increased bioavailability of Cu, Cd, Zn and Pb in soil (Aponte et al, 2020), which results in higher heavy metal toxicity for microorganisms and inhibition of enzyme activities.…”

“…The inhibition of urease activity by crude petroleum has been reported elsewhere. 13,31,32 Margesin 33 found that soil urease activity was stimulated by diesel while inhibited by PAHs. The results in this study further indicated a correlation between the type and concentration of pollutant and its effect on urease activity.…”

“…Crude petroleum consists of linear and branched chain alkanes, cycloalkanes and aromatics as dominant constituents, and also contains small amounts of nitrogen-, oxygen-and sulfur-containing compounds, such as pyridine, phenol and thioether, respectively. 1 Some components, mainly polycyclic aromatic hydrocarbons are hazardous xenobiotics, 2 showing potential teratogenic, carcinogenic and mutagenic activities, 3 and threaten human health when accumulated in crops.…”

“…8 Soil enzyme activities and microbial community structure and diversity are the two most important aspects by which to evaluate soil microorganisms and their biological functions and are thus applied to assess contamination by hydrocarbon contaminants and the evaluation of remediation practices. 3,[9][10][11][12][13][14] Recent advances in molecular biological techniques have enabled rapid proling of microbial ecosystems at the genetic level. PCR-DGGE and a gene clone library were applied by Wu to assess the biodiversity of bacteria, fungi and microorganisms involved in the nitrogen cycle in crude oil contaminated soils before and aer bioremediation.…”

The changes in microbial ecology interpreted from taxonomic and functional genes and biological functions represented by urease and dehydrogenase activities were monitored in soil contaminated with different petroleum hydrocarbons including crude oil, diesel, n-hexadecane and poly-aromatic hydrocarbons (PAHs). It was shown that the presence of n-hexadecane stimulated the activity of indigenous microorganisms, especially alkane degrading bacteria, and led to over 20% degradation of n-hexadecane within one month. No obvious degradation of the other three types of petroleum hydrocarbons was observed. The stimulation effect was most marked in the soil spiked with a medium concentration (2500 mg kg(-1) dry soil) of n-hexadecane. However, the presence of PAHs completely inhibited the previously-mentioned bioactivities of the soil. The content of PAH degrading bacteria, however, increased more than 10-fold, indicating the selection effect of PAHs on soil bacteria. The impacts of diesel and crude oil on the microbial ecology and biological functions varied significantly with their concentration. The disclosure of the ecological and enzymatic responses could be helpful in soil bioremediation.

Heavy metal emission from brick kiln operation in developing countries is one of the major sources of environmental pollution. The present study evaluated the intensity of Cd and Pb pollution and the impact on soil microbial activity in agricultural soils in the vicinity of the brick kiln cluster of Hathazari, Chattogram, Bangladesh. It is a major concern as anthropogenic stress on soil microorganisms is directly related to crop productivity. Soil samples were collected from 21 sites covering 7 locations including the reference sites for the assessment of the toxic impact on soil biota. Soil samples were analyzed using standard procedures. In some of the sampling sites, Cd and Pb concentrations were signifi cantly higher than the reference sites. Metal concentration indicates that the anthropogenic input in the soils was in the range of 0.27 to 1.07 mg•kg -1 of Cd and 19.07 to 52.07 mg•kg -1 of Pb. However, the concentrations of Pb were not in toxic concentration when compared to the standard level by Chinese environmental quality standards for soil. The highest contamination degree (PER) of the soils was 200.87 and the lowest was 115.83. The contamination factor demonstrated that the soils were in the moderate to considerable level of contamination. The results showed that the number of soil microbial population, microbial activity, microbial biomass carbon, dehydrogenase, urease, acid phosphatase and arylsulfatase activities in the reference soil were all higher than in the agricultural soil in the vicinity of brick kiln cluster. Exponential curves showed a signifi cant positive correlation between heavy metal and microbial metabolic quotient (qCO 2 ) indicating metal stress and high concentration of heavy metals decreased microbial biomass and enzyme activity. Soil pH and Cd content were identifi ed as the key infl uential factors controlling soil biological functions. A signifi cantly high correlation was observed for Cd and Pb (r = 0.89, p < 0.001), it suggests the same source of contamination input. Contamination of Cd and Pb is attributed to heavy input of aerial deposits of metal-enriched fumes from brick kiln operation. A signifi cant negative impact of Cd and Pb on soil microbial activities and enzyme activities was also profound from correlation studies and PCA analysis. However, regular application of fertilizer in agricultural soils may have supported adaptation to long-term Cd stress mainly through the maintenance of microbial activity. The study is important in eco-toxicological and biomonitoring aspects as the data on heavy metal toxicity to the soil environment can act as guidelines for the continuation of brick kiln operation and the sustainable utilization of natural resources.
