The fruits were cultivated at one location, while the vegetables were from the other two locations. Recently, an additional hurdle has been added to the formal consumer risk assessment process with the introduction of short-term intake or exposure assessment and a comparable short-term toxicity reference, the acute reference dose. The pre harvest interval (PHI) of imidacloprid, lambda-cyhalothrin, and profenofos on tomato were 2, 6 and 1 days, respectively. The quantities are described, photographs.

A review concerning the determination of pesticide residues in fruit and vegetables is presented. The fruits were cultivated at one location, while the vegetables were from the other two locations. Fruits and vegetables are important componen, essential nutrients that are required for most of the reactions occurring in the body. It is easy to perform and requires less time, to complete. Pesticide legislation in developing countries is generally lacking or not implemented and, this also affects pesticide monitoring since it relies on legislation to be effective (Ecobic, 2001).

Common methods of dietary exposure assessment were based on deterministic calculations, and those have been found to have short comings of only providing exposure for average, consumers while excluding higher consumer, probabilistic risk assessment since it considers all exposure throughout the entire consumer, distribution. The highest dose of the pesticide that, the test organisms is called the no-observed-, in milligrams per kilogram of body weight pe, it is used in calculation of the ADI or the ARf, effects. Many food retailers have developed even more stringent private food safety protocols relating to pesticide use, storage and disposal and passed them on to their suppliers. Probabilistic exposure assessment is based on, the probability of occurrence of the risk and, Deterministic exposure is generally used as a low tier approach to determine whether there, is a course for concern for the defined exposure.
