Summary: Rivers are polluted by various hazardous substances, including pesticides. Pesticide residues from agricultural fields and domestic sewage water contaminate the water, sediment, and fish in rivers. These residues bio-concentrate and bio-accumulate in aquatic organisms, including fish, which are consumed by humans. However, the presence of pesticides in the river Gomti, a tributary of River Ganga in India, does not pose a direct risk to consumers based on human health risk assessment.

Summary: Toxicological studies have found that honeybees' responses to pesticides can vary due to individual differences in pesticide sensitivity and exposure. This study focused on the risk of pesticides to nurse and forager bees, which have different physiological backgrounds. The results showed that forager bees were more sensitive to sulfoxaflor compared to nurse bees, potentially due to differences in body weight. Additionally, foragers consumed more sugar syrup, especially when it was contaminated with pesticides. The study suggests that forager bees should be included in regulatory tests to ensure accurate assessment of pesticide risks to honeybees.

Summary: This research assesses the environmental fate and transport of agricultural pesticide formulation agents using a dynamic modeling approach. Two toxicological concern formulation agents, Naphthalene and Solvent Naphtha (Petroleum), Heavy Aromatic, were simulated in the agriculturally intensive Sacramento River watershed. The predicted transport masses of these formulation agents in surface water were strongly correlated with rainfall and were higher in certain locales at the subbasin level. The potential risks of these formulation agents in the environment require further investigation by modeling and monitoring, especially in areas with heavy usage.

Summary: This study examined pesticide residues in vegetables consumed in Incheon to evaluate food safety. A total of 385 samples of 33 different types of vegetables were collected from the Incheon market in 2021. The residues of 339 different pesticides were analyzed according to the multi-residue methods specified in the Korean Food Code. Among the 385 vegetables, 329 samples (85.5%) showed no detection of residual pesticides, while 56 samples (14.5%) contained residual pesticides, with 13 samples (3.4%) exceeding the maximum residue limit. A total of 34 different pesticide residues were detected, with 8 pesticides exceeding the maximum residue limits (MRLs). The most frequently detected pesticide residues were fluxametamide (7 samples), azoxystrobin (4 samples), chlorantraniliprole (3 samples), flubendiamide (3 samples), and procymidone (3 samples). The risk assessment indicated the highest values when Chinese chives were consumed with terbufos. However, the values of HQ and cHI were lower than 100%. Therefore, the results showed that the detected pesticides posed no potential risk to consumers of vegetables.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.
