Pesticides are widely used in agriculture, but their impact on the environment and human health is a major concern. While much attention has been given to presence soil, water, food, there have few studies airborne pesticide pollution global scale. This study aimed assess extent of atmospheric countries worldwide identify regional differences using scoring approach. In addition analyzing risks associated with pollution, we also examined agricultural practices current air quality standards for pesticides these countries. The scores varied significantly among countries, particularly Europe. Asian Oceanic generally had higher compared those Americas, suggesting relatively level caused by regions. It worth noting that levels, as assessed theoretically, pose minimal humans. However, literature shown excessive exposure present atmosphere various problems, such cancer, neuropsychiatric disorders, other chronic diseases. Interestingly, European highest overall application intensities, this did not necessarily correspond scores. Only established specifically pesticides. Furthermore, across states USA were investigated sampling sites mapped. findings revealed limited or unevenly distributed some Nordic These can help relevant environmental agencies set up comprehensive monitoring networks. Overall, research highlights need create system increase efforts enhance regulation, ensure consistency standards, promote international cooperation.

Pollution by agricultural pesticides is one of the most important pressures affecting Mediterranean coastal wetlands. Pesticide risks are expected to be influenced climate change, which will result in an increase temperatures and a decrease annual precipitation. On other hand, pesticide dosages change given pest resistance implementation environmental policies like European ´Farm-to-Fork` strategy, aims for 50 % reduction usage 2030. The influence use practices on ecological needs evaluated making realistic scenarios. This study investigates how different affect Albufera Natural Park (Valencia, Spain), protected wetland. We performed probabilistic risk assessment nine applied rice production using three climatic scenarios (for years 2008, 2050 2100), dosage regimes (the recommended dose, decrease), their combinations. were used simulate exposure concentrations water column paddies RICEWQ model. effects characterized acute chronic Species Sensitivity Distributions built with toxicity data aquatic organisms. Risk quotients calculated as probability distributions Bayesian networks. Our results show that future projections some studied pesticides, yielding higher dissipation lower dominated temperatures, peaks where heavy precipitation events occur right after application. case shows such azoxystrobin, difenoconazole MCPA posing unacceptable organisms, strategy crucial reduce them.
