Summary: This review examined the impact of occupational exposure to pesticides on the development of depression symptoms in agricultural workers over the past decade. The findings indicate a clear association between pesticide exposure and the incidence of depressive symptoms. However, more high-quality longitudinal studies are needed to control for sociocultural variables and utilize pesticide-specific biomarkers and biomarkers of depression.

Summary: The study conducted in Ardabil province, Iran, with a sample of 370 farmers, found that most farmers use three types of PPE when applying pesticides. Farmers' perception of pesticides' health risks influences their use of PPE, with the highest health hazards related to Paraquat and Chlorpyrifos. Farm size, perception of pesticides' health risks, past experiences, training, and ability to afford PPE costs were identified as the most important predictive factors for the composite index.

Summary: Agricultural intensification is a major driver of the decline of wild biodiversity in farmland, but reducing chemical inputs and increasing organic fertilization can help mitigate the decline in bees and butterflies while promoting the growth of certain species like beetles and earthworms. Preventing ploughing of meadows may also contribute to an increase in soil invertebrate abundance. Furthermore, citizen science programs engaging farmers in monitoring can provide valuable data for identifying agronomic practices that support biodiversity conservation.

Summary: Urban growth and increasing vegetable demand have led to the use of lowlands in Cameroon for agricultural production. This study found positive associations between education level and farm size with the overall quantity of fertilizer used, and positive associations between pesticide usage and the number of years a farm had been cultivated. However, pesticide usage was negatively associated with land ownership. Waterborne disease prevalence was linked to education level, while malaria prevalence was linked to the gender of the farmers. The location of cultivated areas significantly influenced the likelihood of reporting malaria and headaches.

Summary: The paper is motivated by the concern over heavy pesticide use in developing countries and the lack of government efforts to address the problem. It investigates the impact of pesticide use on farm level efficiency using a metafrontier framework with stochastic frontier analysis. The results show that farmers overuse pesticides due to higher expectations of future returns, leading to increased inefficiency.

Summary: Occupational exposure to pesticides in farmers results in significant DNA damage, showing a notable impact and variability in the studies. Smokers who are occupationally exposed to pesticides have slightly reduced DNA damage compared to non-smokers, indicating some genetic toxicity. The study demonstrates a higher risk of occupationally exposed rural workers developing related diseases due to the genotoxic effect of pesticides.

Summary: This cross-sectional study examined farmers' knowledge, awareness, practices, and prevalence of health symptoms related to pesticide exposure. The study found that farmers who applied organophosphates had lower knowledge, awareness, and prevention practices regarding pesticide use compared to those who applied pyrethroids. After adjusting for covariate variables, farmers who applied organophosphates had a significantly higher prevalence of respiratory conditions, neurological symptoms, and neurobehavioral symptoms related to pesticide exposure compared to those who applied pyrethroids.

The task-specific endotoxin concentrations were obtained through meta-regression models. Results showed that tasks such as work in poultry and swine confinement facilities, grinding feed, veterinarian services, and cleaning grain bins had higher endotoxin concentrations, while harvesting or hauling grain and other crop-related tasks had lower concentrations.

Summary: A pilot study was conducted in eastern Iowa to assess human exposure to neon-icotinoids (NEOs) among farming households. The study found that NEOs were detected in both outdoor and indoor water samples, with clothianidin being the most frequently detected NEO. Human exposure to NEOs was also found in urine samples, with multiple NEOs and metabolites being present. Additionally, the study concluded that while water consumption may contribute to exposure, other factors like diet and occupational exposure may play a bigger role.

A study conducted in northeast Iowa farms found high levels of inorganics, organics, and microbial contaminants in private-well tap water. The presence of pesticides and bacteria in the water exceeds safe limits, highlighting the need for residential treatment systems and increased monitoring of rural private-well homes.

Summary: Due to its simple process, environmental friendliness, and low operating costs, biometallurgy has become a popular technology for metals recovering from low-grade ores and tailings. An optimized agar was used to isolate and grow functional bacteria, resulting in the successful isolation of six functional stains. These strains were further tested for their ability to leach metals from polymetallic sulfide tailings, with significant improvements observed when the strains were mixed together. The selection of leaching process should be based on tailings composition and target metals.

Summary: This study examines the association between urban Green and blue spaces (GBS) exposure and Emotion and behavior problems (EBP) in youth populations. The findings suggest that higher exposure to GBS, particularly green spaces (GS) and blue spaces (BS), is associated with a decrease in the risk of developing total difficulties in young individuals. The joint effect of GS and BS may also contribute to the decrease in EBPs.

This study investigated the effects of oral gestational exposure to particulate matter (PM) on ultrasonic vocalizations (USV). The findings suggest that this exposure may lead to social deficits and abnormal gene expression related to neurotransmitter systems. Further research is needed to better understand the effects of air pollution on neurodevelopmental disorders and the neurotransmission systems involved.

Summary: The present study investigated the sustainable approach for wastewater treatment using waste algal blooms. The biochar produced by the marine algae Ulva reticulata was used to remove chromium, nickel, and zinc from aqueous solutions. The study examined the adsorbents' properties and stability using SEM/EDX, FTIR, and XRD. The results showed that the biochar had high removal efficiency for the toxic metals, and the packed bed column effectively removed the heavy metal ions. The Thomas and Adams-Bohart models were found to best fit the regression values, and desorption studies were conducted to understand the sorption and elution processes.

Traditionally, spatial and spectral parameters have been used as predictor variables, but the temporal dimension is often overlooked. This study demonstrates the value of incorporating temporal indices in the model, leading to significant performance improvements. The temporal-spatial-spectral covariate combinations used in a random forest (RF) algorithm achieve satisfactory mapping accuracy and outperform other methods.

In this study, a series of catalysts with different elemental doping were prepared using a simple and environmentally friendly method. The S-doped NiCo2O4 catalyst showed excellent catalytic performance for the removal of Tetracycline, with significantly increased kinetic constant and high oxidation and mineralization efficiency in a wide pH range. The degradation process was dominated by non-radical oxidation pathway after S doping, and the overall process moved towards low toxicity.
