Abstract
In Egypt, exportation of fruits and vegetables was affected with the
level of contamination by pesticides residues .Organochlorine,
orgnophosphrous and organonitrogen pesticides were the main contaminants
found in these commodities. According, monitoring programs of pesticide
residues in the fruits and vegetables in the governorates in which these
commodities are cultivated and at exportation ports are required to generate a
flow of data that serves in following up the regulation of pesticides use and
evaluates the situation of fruits and vegetables contamination with pesticides
residues in order to compare them with the corresponding FAO/WHO
acceptable daily intake for risk assessment purposes and enabling the
decision –makers to take the convenient corrective actions to minimize health
hazards and adverse impact of pesticide use.Oraganophosphorus compounds
are among the most acute toxic pesticides on the market worldwide, and their
registration is being phased out or has been canceled in many countries. On
the other hand agriculture products such vegetables and fruits are important
components of the human diet as these are sources of vitamins and minerals.
But, these commodities could also be a potential source of harmful and toxic
pesticides. Thus, food safety has become a major public concern worldwide.
Heavy metals may contaminate different plants causing serious health
hazards such as injury of kidney, symptoms of chronic toxicity, renal failure
and liver damage. The source of environmental pollution with toxic metals
are quite varied, ranging from industrial and traffic emissions to the use of
purification mud and agricultural expedients, such as cadmium-containing
dung, organic mercury fungicides and the insecticide lead arsenate.
