Ochratoxin A (OTA) Is a nephrotoxic mycotoxin that oiso possesses carcinogenic, teratogenic, genotoxic and immuno suppressive potential'. The international agency for research on cancer has classified OTA as a possible human carcinogen. The European Commission has prescribed maximum residue limits (MRLs) for OTA in cereals, dried vine fruits, wine, infant foods and coffee. A maximum OTA limit of 5 and 1 Oppb have been prescribed for roasted and instant coffee resepctlvely.

To study the influence of seasonal variation on the nitrate contamination of groundwater, water samples were collected during the pre and post-monsoon seasons from open wells, bore wells and hand pumps at different villages spread over in the 18 blocks of the Coimbatore district of Tamil Nadu. The water samples were analysed for pH, EC and NO3-N content. Results indicated that the groundwater of different blocks of Coimbatore ranged from neutral to alkaline in reaction and saline in nature. The overall mean NO3-N content of groundwater samples of different blocks varied from 5.20 to 9.52 mg L-1 with the overall mean value of 6.74 mg L-1 and it is below the critical level of 10.0 mg L-1. The higher mean NO3-N content was observed in groundwater samples collected from Gudimangalam block followed by Periyanaickenpalayam and Sultanpet blocks. The temporal variation in NO3-N content of groundwater samples was observed, being higher in the post monsoon than in the pre monsoon season.Keywords
