Measurement of Lead concentration in Agricultural field

To determine the lead concentration in soil and its toxicity in crops, it's crucial to perform accurate chemical analysis, assess lead accumulation in crops, and compare the results to established safety limits. The results help in understanding environmental risks and making decisions about soil management or crop selection to ensure food safety. To determine lead concentration in soil samples taken from Bahraich, Lucknow, Meerut, and Bareilly along with quantifying its toxicity, using dithizonate assay by spectrophotometric analysis of lead dithizonate so formed at 604 nm. The lead concentration in sample from Bareilly was found to be 0.307 mg/lt and its toxicity level within the crop (here wheat) was found to be 0.0906 mg/lt.
