In Paraguay, pesticides are the causative agent in 13.7% of poisonings, especially organophosphorus compounds. Such poisoning produces the inhibition of acetylcholinesterase generating three possible clinical conditions: acute poisoning, intermediate syndrome or late neurotoxicity. We present 15 cases of acute poisoning, ten women and five men from a rural community between 5 and 67 years of age, whose symptoms began after using water contaminated by pesticides from the community network. The most common symptoms were nausea and vomiting, followed by abdominal pain, headache, fever, itching, red eyes and sweating. Five patients underwent blood tests for blood count, renal and liver function and serum cholinesterase, with results within the reference values; just one patient had high liver enzymes.In two samples from the community water supply network the active compound detected was profenophos. It is essential to train primary health care personnel to identify cases of acute pesticide poisoning in a timely manner to provide appropriate treatment, especially in rural areas. Additionally, it is necessary that responsible institutions monitor compliance with environmental regulations in these areas to avoid such incidents.

Pesticides are widely used to control pests, but their widespread use raises concerns regarding potential health risks for humans. There are several routes through which pesticides can be ingested, inhaled, and absorbed, resulting in acute and long-term health consequences. This systematic review synthesizes the available evidence regarding the health risks and long-term effects of pesticide exposure, with a particular focus on epidemiological and toxicological studies.

Butyrylcholinesterase plays an indispensable role in organisms, and its abnormal expression poses a significant threat to human health and safety, covering various aspects including liver-related diseases, diabetes, obesity, cardiovascular and cerebrovascular diseases, and neurodegenerative diseases. In addition, toxic substances such as organophosphorus and carbamate pesticides markedly inhibit BChE activity. BChE activity serves as a critical parameter for the clinical diagnosis of acute organophosphorus pesticide poisoning and the evaluation of organophosphorus and carbamate pesticide residues.

An ideal green leaf-deposited pesticide formulation should offer advantages such as good water dispersibility, strong foliar affinity, sustained or controlled release of active ingredients, photostability and rain-fastness, minimal nontarget toxicity, use of nontoxic organic solvents, and degradable adjuvants. In line with this objective, we present green preparation of a colloidal pesticide formulation using optimized lysine-derived carbon dots (LysCDs)-modified CaCO (LysCDs/CaCO) particles as the carrier and abamectin (Abm) as the active ingredient. The loading capacity of abamectin in this colloidal pesticide (LysCDs/CaCO/Abm) is 1.

Chlorpyrifos (CLP) and deltamethrin (DTM) are among the most widely utilized organophosphate and pyrethroid insecticides globally. Their simultaneous presence in aquatic environments poses significant threats to fish health and challenges the sustainability of aquaculture practices. Despite their prevalence, the combined toxic effects of CLP and DTM on hook snout carp (Opsariichthys bidens Günther) remain insufficiently understood.

Based on effect data, regulatory acceptable concentrations (RACs) are derived for surface waters to avoid unacceptable effects on the environment. RACs often relay on acute tests with single species, which may underestimate the effects under field conditions. Therefore, we applied a higher tier approach with artificial indoor streams (AIS).
