Cadmium was detected in 78 of 116 samples of leafy vegetable, although without any exceeding the maximum limits. However, lead was detected in 99 samples, of which 39 exceeded the maximum limits (0.3 mg kg-I) and 56 medicinal plant samples of 70 had lead levels above 0.5 mg kg-I. Copper was detected in 69 medicinal plant samples, of which 58 samples contained levels higher than 10 mg kg-I. However, cadmium was only found in 43 of samples with only two of 70 samples above the maximum limit.
