Pesticides, at least dimethoate, were found at higher
concentrations in the peel of watermelon. It would be advisable
to wash the whole fruit before cutting it open with a
knife. This is to avoid and reduce the contamination of
pesticides into the edible flesh of watermelon. Washing the
whole watermelon fruit before cutting it open is likely to
reduce pesticide contamination. Even though the washing
experiment was not performed to confirm this, previous
studies have proven the advantage of washing in decreasing
pesticide contamination.
Dimethoate and metalaxyl emerged as the most commonly
used pesticides in the cultivation of durians. However,
the levels of pesticides detected in durian samples
were well below their recommended MRL values. For
example, the mean level of metalaxyl found in durian
samples was 1.4 ppb corresponding to approximately 3 %
of the suggested MRL for metalaxyl in durians (50 ppb).
Dimethoate was detected in 13 samples with a mean concentration
of 2.6 ± 1.3 ppb, corresponding to about 13 %
of the recommended MRL for dimethoate in durians
(20 ppb).
