The majority of the heavy metal pollution in the air comes from industry .Apart from originating from the soil and water, pollution also affects agricultural crops and can cause serious health issues in humans .People always want to consume meals that are good for the environment and their health .This study set out to quantify the amounts of different heavy metals in 10 samples (Two replicates for each sample) of imported canned tomato paste that were sold in Libyan markets. This was necessary since tomatoes are a frequently eaten canned product that might get contaminated. The samples were measured with an Atomic Absorption Spectrophotometer (AAS), and the findings indicated that the lead concentrations in the samples ranged from 0.137±0.00 mg/kg to 1.11±0.00 mg/kg, the cadmium concentrations were between 0.043±0.00 mg/kg and 0.107±0.00 mg/kg, and the iron values are between 3.03±3.40 mg/kg and 0.90±0.00 mg/kg. Additionally, the outcomes showed that every sample—aside from one—was zinc-free. All tomato paste samples usually had levels of cadmium below acceptable norms, while the remaining samples were all below FAO/WHO approved limits.

Additional comprehensive study ought to be conducted in other parts of Libya.
To obtain precise data, we advise employing more advanced analytical methods.
For canning, use glass jars or heavy metal cans that have been lined with an inert insulating substance.
- Select the right kind of raw material (tomatoes) and other supplies for manufacture.
Researching soil to find out how much of these minerals are contaminated.
Establish awareness campaigns to encourage people worldwide to use less fertilizer, as this is a major contributor to pollution.
-Aiming to shorten the storage duration as much as feasible since the amount of heavy metals present and storage time are directly correlated.
