Abstract

Water and soil property was assessed with the estimation of physiochemical constituents and heavy metal contaminations, both are responsible for serious environmental and health related issues. In this investigation, the analysis focuses on the estimation of physiochemical parameters and quantification of heavy metals (Cd and Pb) in water and soil samples from automobile service stations (S1N1, S2V2 and S3X3). The temperature of soil and water ranged from 28°C to 29 °C depending on depth of soil sampling and due to the continuous flow of vehicle washing water discharges, while pH was measured as 7.6 to 8.5 due to release of battery effluent and hydrocarbons. EC was recorded as 201 to 305 (µScm-1) in three stations of automobile soil and water effluents. One-way ANOVA showed the significance of 0.002164 < 0.05 P-value on temperature of soil samples and 0.081887 > 0.05 P-value explained the variability in water samples of three automobile workstations. The pH of soil sediments showed insignificance (0.075972 >0.05 P-value) and significant in water samples (0.01541 < 0.05 P-value). EC of soil and water demonstrated the significance at < 0.05 P-value. Heavy metals such as Cadmium and Lead was also estimated in soil and water samples of all three automobile workstations and expressed as ppm/ mL. Both the metals were an evident of insignificance at < 0.05 P-value by one-way ANOVA among the data sets of soil and water collected from three stations. The result of Cadmium was above the permissible limits set by WHO due to the automobile discharges and conclusively it is hereby recommended that a separate portion of land be set apart for automobile workshops which can be called mechanic village as it is in some cosmopolitan areas in this library. In addition to this, microbial diversity was also examined in study samples of soil and water from automobile work stations. Bacilli sps was a predominant in soil samples and major screened species in water samples were Bacilli and Diplobacilli sps which further employed for pure culture and characterized cultural prospective.

Conclusion

According to the investigation, the water and soil sediments were purely contaminated with various hydrocarbon effluents and Heavy metals as well as the strong bacterial community was noted in the automobile effluent environment. The physiochemical analysis revealed the consistency of soil and water as well as bacterial diversity in the sites of automobile workshop. The bacterial community was further the isolated strains were scrutinized for heavy metals (Pb) resistance in minimal media. From the heavy metal plates, 7 isolates in soil samples and 12 isolates in water samples have been determined for the tolerance of heavy metals. The positive strains were afterward employed for characterizations and hydrocarbon degradation studies.
