Passive monitoring techniques to evaluate environmental pesticide exposure: results from the Infant's Environmental Health study (ISA)
(Elsevier, 2020-02-08)
Background: Pesticides used in agriculture may expose populations living nearby. Costa Rica is a major bananaexporting country, its production depends on extensive pesticide use.
Objectives: To evaluate environmental ...
Prenatal pesticide exposure and respiratory health outcomes in the first year of life: Results from the infants’ Environmental Health (ISA) study
(Universidad Nacional, Costa Rica, 2020-01-29)
Background: Growing evidence suggests that pesticide exposure may influence respiratory health, but data in young children are very limited. We examined the association of prenatal pesticide exposure with lower respiratory ...

Background:Pesticides and metals may disrupt thyroid function, which is key to fetal brain development.Objectives:To evaluate if current-use pesticide exposures, lead and excess manganese alter free thyroxine (FT4),freet ...
The effect of the insecticide diazinon on the osmoregulation and the avoidance response of the white leg shrimp (Penaeus vannamei) is salinity dependent
(Elsevier, 2020-12-15)
Diazinon is one of the insecticides that represent a high risk for Costa Rican estuarine environments due to its
widespread use in pineapple plantations. In estuaries, organisms are frequently submitted to stress caused ...
Can a mixture of agrochemicals (glyphosate, chlorpyrifos and chlorothalonil) mask the perception of an individual chemical? A hidden trap underlying ecological risk
(Elsevier, 2022-01)
As aquatic environments associated with conventional agriculture are exposed to various pesticides, it is
important to identify any possible interactions that modify their effects when in a mixture. We applied avoidance ...
