Heavy Metal Analysis In Summer Season

Heavy Metal Analysis

In present study we have observed that In case Agriculture zone the maximum pH concentration 8.6 is detected in sample-3 summer season and minimum pH concentration 6.2 is observed in sample-2 rainy season. In case of Industrial area maximum pH concentration 8.1 are found in sample-2 summers season whereas minimum pH concentration 6.2 are found in sample-10 winter season. In case of Domestic area maximum pH concentration 7.9 is detected in sample-2 summer season and minimum pH concentration 6.3 is observed in sample-10 rainy season. In case of Transport area high value of pH is observed 8.4 sample-4 in winter season and lowest value is analysed 6.4 sample-6 in rainy season. In case of Mining area high value of pH is observed 7.8 sample-2 in summer season and lowest value is analysed 5.6 sample-8 in winter season.

In Agriculture zone the maximum Copper concentration 31.19 mg/kg is detected in sample-6 summer season and minimum Copper concentration 13.66 mg/kg is observed in sample-2 rainy season. In case of Industrial area maximum Copper concentration 54.36 mg/kg are found in sample-9 summers season whereas minimum Copper concentration 30.37 mg/kg are found in sample-1 rainy season. In case of Domestic area maximum Copper concentration 27.48 mg/kg is detected in sample-8 rainy season and minimum Copper concentration 15.36 mg/kg is observed in sample-5 winter season. In case of Transport area high value of Copper is observed 45.34 mg/kg sample-4 in winter season and lowest value is analysed 28.12 mg/kg sample-6 in rainy season. In case of Mining area high value of Copper is observed 59.47 mg/kg sample-6 in summer season and lowest value is analysed 36.41 mg/kg sample-7 in rainy season. Though the copper concentrations in all the sampling sites are lower than the maximum permissible limit for Cu set up by EU, which is 140 mg/kg.

In Agriculture zone high value of Lead concentration is observed 71.8 mg/kg sample-7 summer season and minimum value is observed 30.6 mg/kg sample-9 in rainy season.In case of Industrial area maximum Lead concentration 68.3 mg/kg are found in sample-4 summer season whereas minimum Lead concentration 23.6 mg/kg are found in sample-10 winter season. In case of Domestic area maximum Lead concentration 65.8 mg/kg is detected in sample-7 winter season and minimum Lead concentration 28.3 mg/kg is observed sample-10 in rainy season.

In case of Transport area high value of Lead is observed 70.6 mg/kg sample-7 in summer season and lowest value is analysed 33.4 mg/kg sample-10 in winter season. In case of Mining area high value of Lead is observed 68.4 mg/kg sample-4 in summer season and lowest value is analysed 29.4 mg/kg sample-8 in winter season. All Lead content of the entire sample were below the recommended level.

In Agriculture zone high value of Chromium concentration is observed 69.5 mg/kg sample-7 summer season and minimum value is observed 41.8 mg/kg sample-1 in rainy season. In case of Industrial area maximum Chromium concentration 78.2 mg/kg are found in sample-2 rainy season whereas minimum Chromium concentration 49.6 mg/kg are found in sample-3 winter season. In case of Domestic area maximum Chromium concentration 48.6 mg/kg is detected in sample-1 summer season and minimum Chromium concentration 22.3 mg/kg is observed sample-10 in winter season.

In case of Transport area high value of Chromium is observed 72.6 mg/kg sample-8 in summer season and lowest value is analysed 50.8 mg/kg sample-6 in rainy season. In case of Mining area high value of Chromium is observed 65.6 mg/kg sample-4 in rainy season and lowest value is analysed 52.8 mg/kg sample-9 in winter season. All Chromium content of the entire sample were below the recommended level Indian Standards (1998 ) , European Union Standards (2002 ). But in Agriculture Zone sample-2, Transport Zone sample-8, and Mining Zone sample-4 are higher than the SQGL recommended level value as 64 mg/kg.

In Agriculture zone high value of Cd concentration is observed 2.8 mg/kg sample-8 summer season and minimum value is observed 1.0 mg/kg sample-3 in winter season. In case of Industrial area maximum Cd concentration 6.2 mg/kg are found in sample-6 summer season whereas minimum Cd concentration 1.9 mg/kg are found in sample-10 winter season. In case of Domestic area maximum Cd concentration 2.4 mg/kg is detected in sample-8 rainy season and minimum Cd concentration 0.3 mg/kg is observed sample-2 in winter season.
