In vegetable growing areas in suburb and adjacent of Hanoi, proportion of samples hawing plant protection chemical residuces exceeding acceptable limit is relatively high (35 percent). To minimize impact of the residues, it is necessary to determine safely isolated duration of the chemicals on agro-products. The exponential regession of timmes, Freshe can be used to estimate the duration. Under humid tropical conditions in Vietnam, isolated duration of chemicals tends to be shorter than that recommended by manufacturers and in other temprate countries.
