Risk factors, erythrocyte acetylcholinesterase inhibition, and self-reported symptoms of pesticide intoxication among farmers in Thailand: A cross-sectional study.

Background: Organophosphate and carbamate pesticides are widely used, and their adverse health effects remain a serious problem.

Objectives: This investigation aimed to describe risk factors, erythrocyte acetylcholinesterase (AChE) inhibition, and self-reported symptoms and to derive an association between influence factors and erythrocyte AChE inhibition among farmers in Thailand.

Methods: A cross-sectional study was conducted on 71 farmers from August to October 2022.

Impact of environmental heat exposure on the health status in farmworkers, Nakhon Ratchasima, Thailand.

Background: Thailand is a tropical developing country which has a serious increase in health risk due to hot weather exposure among outdoor workers.

Objectives: The aims of this study were to compare the factors related to environmental heat exposure in three different seasons, and to assess the relationship between environmental heat and dehydration status in each season among farmworkers in Nakhon Ratchasima, Thailand.

Methods: A semi-longitudinal study was carried out in 22 male farmworkers throughout a year of farming.

Pesticide toxicity assessment and geographic information system (GIS) application in small-scale rice farming operations, Thailand.

The objectives of the study were to evaluate the impact of pesticide exposure on farmer health during non-active rice farming and active rice farming periods and present the change in the individual cholinesterase activities (%reduction) on the geographic information system (GIS) mapping in Nakhon Ratchasima Province, Thailand. Acetyl- and butyryl-cholinesterase (AChE and BuChE) activities were monitored during both study periods using Test-mate ChE (Model 400). The location of paddy fields was specified using Garmin geographic positioning system MAP 62s.
