Abstract: Volatile organic compounds (VOCs) occur in traces in atmosphere and even in trace levels, these compounds pose serious health hazard. Sample stability, recovery, effect of temperature and moisture management are a few critical points taken into consideration while sampling and analysis of polar and non polar VOCs. In the present work, stability study was carried out for polar and non polar VOCs in SUMMA stainless steel canister. Compounds recoveries were assessed in dry and humid canisters.Canister samples were prepared with 0, 25, 50 and 100% humidity. Moreover, the study with each humidity level was performed with two different concentrations (approx 50 & 500 µgm-3) of each compound to evaluate the influence of lower/higher concentration. Before starting experiment, various parameters used for the measurement of VOCs from canister system were optimized and method detection limit was calculated as the accuracy of analytical measurement is the key part of stability study. Polar compounds like alcohols were poorly recovered from dry canisters. Sulfur and chloro compounds were recovered in the range of 12-68% over one month period. Aromatic and aliphatic hydrocarbons appeared to be unaffected. In presence of humidity in canister, alcohols showed better recovery but recovery was sometime irregular especially if they are in low concentration. Recovery of sulfur compounds improved significantly in presence of humidity while chloro compounds were recovered about 60-70% even if humidity is there. Overall, humidity is proved to be essential for the recovery of alcohols, sulfur and chloro compounds and 50% humidity was the best suitable humidity. Nonpolar compounds remained unaffected irrespective of humidity level.

Abstract: An investigation has been made to ascertain the effect of tannery effluent associated with climate change on river water samples collected from confluence point, upstream and downstream located near Jajmau area at Kanpur. All the samples analyzed for physico-chemical parameters including estimation of chromium. The pH at confluence point (Q) was significant (P<0.05) alkaline (7.9±0.13) during summer as compared to upstream point P3 due to dumping of untreated tanneries effluent, which suggested that utilization of salts for leather tanning process. Study shows that a significant (P<0.05) decrease in DO values (3.79±0.101 mgL-1) at summer, although the higher level of DO (6.76±0.13) during monsoon season might be attributed to the dilution of the effluent by rain water. The level of BOD (41.07±1.268 mgL-1) shows a significant (P<0.05) increase at confluence point during as compared to upstream point (P3) during summer. Although the level of COD at different sampling points affected with climate changes but it was not significant. However this study also revealed a significant negative correlation showing that as BOD and COD increases in values DO decreases with correlation of r = -0.944 (t= 6.978, P<0.05 for BOD) and r = -0.970 (t= 9.696, P<0.05 for COD). These correlation between BOD, COD and DO suggest a similar cause. The correlation analysis of TDS versus BOD and COD gives a positive correlation (r =0.9408 & r =0.8667 respectively) showing that as TDS increase BOD and COD also increases. Theses correlation analysis shows that levels of TDS, BOD and COD are highly correlated with each other in sampling area during different climate change. Chromium levels are high (52.12±15.52 mgL-1) in almost all sampling points with climate change. Tannery effluent with climate change shows highly adverse effect on river Ganga.
