“…One of the most relevant activities in the agricultural sector is floriculture, this can be defined as the branch of ornamental horticulture that is dedicated to the development and production of ornamentals and cut flowers (Adeola et al, 2018;Nassar and Ribeiro, 2019;Paiva, 2018). In Colombia the ornamental sector and its distribution chain contributes 7% of the agricultural national gross domestic product and is one of the industries that drives economic development and at the same time one of the industries that generates the highest level of employment (Rodríguez and Junco, 2016).…”

Carnation production in Colombia, the world’s main exporter, takes place entirely in naturally ventilated greenhouses. This type of structure presents non-homogeneous microclimate conditions which differentially affect crop growth and development, which is why this issue has been of great research interest in recent years. The objective was to determine the microclimatic behavior of a passive spatial-type greenhouse used in Colombia for carnation production. The experimental approach included the collection of meteorological data in the external environment through a weather station and in the inside of the greenhouse through a grid of 40 sensors uniformly distributed in a horizontal plane. Data processing to determine the spatial variability of temperature, relative humidity and vapour pressure deficit (VPD) is done by using geostatistical techniques and predicting these variables at unsampled points through the ordinary Kriging method. The main results obtained allowed us to determine that the conditions generated inside the greenhouse are not the optimal ones recommended for carnation production and that, in addition, the behavior of the variables studied shows a heterogeneous distribution, obtaining spatial variations in the horizontal profile evaluated for the night period of 0.5 °C, 9.1% and 1.5 kPa and for the daytime period of 7.2 °C, 42.6% and 1.5 kPa for temperature, humidity and VPD respectively.

“…Although acute toxicity is well known for many pesticides, human data on their chronic effects are much more limited, even when chronic exposure to these xenobiotic compounds could trigger some biochemical alterations on target organs and lead to the appearance of several diseases [ 23 ]. Farmers represent a highly vulnerable population, due to the combination of unique social and cultural risk factors as well as exposure to hazards inherent in agricultural work [ 24 ]. Most of the research conducted to date has focused on operators or workers handling concentrated pesticides by loading, mixing, spraying, or cleaning equipment.…”

“…However, pesticides can spread even very far distances from application areas via atmospheric transport, volatilization post-application, and spray drifts. Thus, it is important to determine the effects of long-term exposure to low levels of pesticide on residents surrounding intensive agricultural areas [ 1 , 24 ]. Therefore, when women are exposed over long periods of time to certain pesticides, several types of adverse reproductive outcomes may occur, leading to developmental problems in their offspring.…”

Pesticides are substances that have become widely used in agriculture and the human exposure to these substances may cause adverse health outcomes. Non-occupational exposure to them can come from many sources, such as food or water. For occupational exposure, many studies have been conducted in men, as they have been mostly in charge of work related to these substances. Nonetheless, the information available concerning the exposure in women is very scarce. In addition, an important differentiation between rural and urban areas has been established, rural areas being known as the most exposed ones due to plantation fields. However, the application of higher concentrations of herbicides in small urban areas is taking a lot of importance currently as well. Regardless of gender, the conditions of exposure, and the environment, the exposure to these pesticides can have different effects on health from early life stages, resulting in different outcomes ranging from neurodevelopmental effects in newborns to different types of cancers. In this review, we discussed the toxicity of the most commonly used pesticides and the main impact on the health of the general population, focusing mainly on the effect in women from both rural and urban areas, and the different stages of development, from pregnancy or lactation to the outcomes of these exposures for their children.

“…Argentinian regulation (Law 24557, resolution 37/2010) establishes an annual measure of AChE in erythrocytes in OE subjects. In accordance with regulations from developed countries, a single annual measure of the enzyme activity should not be useful in terms of health issues (Nassar and Ribeiro, 2020).…”

The characterization of the population exposed to pesticides and the use of effective biomarkers to evaluate potential health effects are determinant to identify vulnerable groups, understanding the causality of diverse pathologies and propose prevention policies. This is particularly important in countries where intensive agricultural practices had an explosive expansion in last decades.The aim of this study was assessing the usefulness of two exposure indexes questionnaire-based: Intensity Level of the pesticide Exposure (ILE) and Cumulative Exposure Index (CEI) and their scales, in terrestrial applicators of pesticide from the Province of C ordoba (Argentina). The analysis was performed contrasting ILE and CEI results with perceived symptomatology, in addition to effect and exposure biomarkers. A cross-sectional study was designed to compare pesticides body burdens and effect biomarkers between subjects occupationally (OE) and non-occupationally exposed (NOE) to pesticides. Prevalence of perceived symptomatology and genotoxicity damage was higher in the OE group. The exposure condition was the only variable explaining these differences. Significant associations were found between CEI and neurologic symptomatology (p < 0.05) and between ILE and plasmatic cholinesterase (p < 0.1). However, residues of HCB, β-HCH, α-endosulfan, pp'DDE, endrin, β-endosulfan, pp'DDT, endosulfan sulfate and mirex were found in blood samples from both groups. To our knowledge, this is the first report on pesticides body burdens in occupational exposure settings in Argentina. So far, our current results indicate that the occupational condition affects the health of the workers. Significant associations found between symptomatology and biomarkers with scales of CEI and ILE suggest their usefulness to verify different levels of exposure. Further research is necessary to propose these indexes as an affordable tool for occupational health surveillance in areas with difficult access to health care centres.
