Changes in As concentration, precipitation and temperature below in situ conditions in cases of I-T1 and I-T2.In circumstances of I-T1 and I-T2, As leaching concentrations from the very first and second collected leachates had been reasonably higher, and then gradual decreases had been observed. That is resulting from the reasonably higher temperatures in the summer time month (May perhaps to August) along with the heavy rainfall from July to August till the recovery in the initial and second leachates. This suggests that not simply had been there decrease water contents in the in situ columns but also a larger temperature, which induced the oxidation of sulfide minerals within the columns. three.three.six. Significance of Environmental Situations for As Behavior By comparing the results of column experiments performed within the laboratory and in situ, As leaching concentrations were greater, the pH values had been slightly reduced, the Eh values have been larger, along with the SO4 2 – concentrations had been higher beneath in situ circumstances. ML-SA1 MedChemExpress Moreover, since the in situ column experiments had been carried out in summer season to autumn, the temperature was somewhat higher and heavy rainfall events have been observed. Meanwhile, nearly constant water content material and continual room temperature have been established for the laboratory columns. Based on the comparison amongst the laboratory columns and also the in situ columns, the oxidation of sulfide minerals within the rock samples, or weathering of the rock, is accelerated by the effects of greater temperature and decrease water contents on account of rainfall conditions.
