Potential risks of dietary exposure to chlorpyrifos and cypermethrin from their use in fruit/vegetable crops and beef cattle productions.
ARTÍCULO PUBLICADO EN REVISTA EXTERNA. The active ingredients (a.i.) used as pesticides
vary across regions. Diet represents the main source of
chronic exposure to these chemicals. The aim of this
study was to look at the pesticides applied in fruit, vegetable,
and beef cattle productions in Mendoza (Argentina),
to identify those that were simultaneously used by
the three production systems. Local individuals (n = 160),
involved in these productions, were interviewed. Glyphosate
was the a.i. most often used by fruit-vegetable
producers, and ivermectin by beef cattle producers.
Chlorpyrifos (CPF) and cypermethrin (CYP) were the
only a.i. used by the three production systems. The
survey revealed that CPF, CYP, alpha CYP, and CPF+
CYP were used by 22, 16, 4, and 20% of the fruit and
vegetable producers, respectively. Regarding beef cattle,
CYP was used by 90% of producers, CYP + CPF formulation
by 8%, and alpha CYP by 2%. The second approach
of this study was to search the occurrence of CYP
and CPF residues in food commodities analyzed under
the National Plan for Residue Control (2012–2015). CYP
residues found above the LOD were reported in 4.0% and
CPF in 13.4% of the vegetable samples tested, as well as
in 1.2 and 28.8%, respectively, of the fruit samples tested.
Regarding beef cattle, CYP residues were reported in
2.3% and organophosphates (as a general pesticide class)
in 13.5% of samples tested. In conclusion, consumers
may be exposed simultaneously to CPF and CYP, from
fruits, vegetables, and beef intake. Accordingly, the policy
for pesticide residues in food and human risk assessment
should account for the combined exposure to CPF
and CYP. Moreover, appropriate toxicological studies of
this mixture (including genotoxicity) are warranted. Sitio de la revista: https://link.springer.com/article/10.1007/s10661-018-6647-
