In this study, a large-scale manure-belt laying hen house located in Beijing, China was selected as experimental site for study of emission rates (ER) chemical compositions PM2.5 PM10 3 seasons, namely, summer, autumn, winter, to investigate their possible influences on ambient air quality human health. The results showed that mean ER winter were 9.0 ± 1.7, 2.4 0.7, 1.9 0.7 mg hen-1 d-1 (P < 0.05), 30.7 1.1, 12.8 1.5, 10.9 0.9 respectively.

Abstract There is a long history in environmental sciences to investigate and understand the fate of chemicals environment. For pesticides, this has led systematic assessments compounds by both academic regulatory bodies, particularly for soil water. As we show here, recent years, there an increasing interest potential presence pesticide residues air related exposure risks. Based on literature review years 2002–2022, find growing number monitoring studies with average 6.7 studies/year since 2020, passive sampling methods contributing significantly rise. Most are concentrated Europe North America, France leading studies. However, due lack harmonization, thus, use diverse approaches, it remains challenging derive risks, assess data quality studies, compare datasets. In perspective, focus current emerging trends different approaches highlight how they influence interpretation data. To improve comparability utility data, ensure that monitorings meet certain requirements, propose path forward, including: (1) Standardization harmonization methods: Adopting well-characterized widely applied from research as basis standardizing monitoring, clear distinction between relevant total concentrations. (2) Tiered approach programs: A dynamic concept where initial identifies followed active quantitative and, if necessary, extensive programs. This balances need detailed resource constraints. (3) Data transparency: Public availability reporting methods, analysis, uncertainties crucial credibility Overall, see standards critical assessing risks pesticides informing decisions mitigation strategies. Collaboration atmospheric community strongly recommended leverage existing expertise sampling, interpretation.

Among the most immediate drivers of American burying beetle ( Nicrophorus americanus Olivier) declines, nontarget toxicity to pesticides is poorly understood. Acute, episodic exposure neonicotinoid insecticides at environmentally relevant concentrations linked negative impacts on beneficial terrestrial insect taxa. Beyond mortality, behavioral indicators are often better suited assess sublethal effects residual in environment. First, spp. congeners were used generate and identify a low-dose rate (lethal dose 10%; LD10) from an acute, 24-hour concentration-series was confirmed by LC–MS/MS. Next, we evaluated single repeated (LD10 = 58.9 ng/beetle) imidacloprid N . behavior (10 minutes post-dose) mortality days post-dose). Behavior parameters analyzed using EthoVision-XT. Control significantly less mobile, demonstrating death-feigning, anti-predator behavior. Single LD10 dosed hyperactive, traveling over 4 times farther (total distance; p 0.03) faster (mean velocity; 0.02) than controls. extended their wings without taking flight flipped backs. All control survived 10 post-dose; exhibited 30% 50% respectively. A event sufficient elicit greater movement high predation risk behaviors, whereas did not worsen impairment but increased time. Collectively, generalized linear mixed models indicated that distance traveled, velocity, significant predictors mortality. Recently reclassified, federally threatened may be insecticide previously thought vulnerable episodic, exposure.

Abstract Adult mosquitoes are vectors for many infectious diseases, such as the dengue, Zika, and West Nile viruses, thus significant threats to public health. Reducing mosquito populations decreases risk of vector-borne diseases in human populations. Integrated management includes targeting larvae with biological controls insect growth regulators, while adulticides commonly used adult population reduction. Secondary effects these insecticides can include insecticide resistance, non-target effects, potential health impacts. Emerging control techniques, sterile techniques (SIT), incompatible (IIT), use genetically modified mosquitoes, Oxitec increasingly being successfully implemented. These have advantages but also challenges. The challenges detailed, future adoption release is discussed.

Wild and managed bees are critical for the stability of trophic webs, angiosperm reproduction, agricultural productivity. Unfortunately, as many 40% crop pollinators in a steep decline due to habitat loss exposure agrochemicals. Pyrethroids, neonicotinoids, macrocyclic lactones among agrochemicals toxic pollinating insects that used extensively industrial beef cattle feeding operations throughout world. Fugitive feedyard particulate matter (PM) transports into surrounding environs. To determine impact agrochemical-laden on bee pollinators, we conducted situ experiments wherein honeybees mason were placed downwind upwind feedyards (N = 40). Concurrent, colocated total suspended samples contained multiple insecticides parasiticides including pyrethroids, lactones, significantly higher concentrations (bifenthrin, 8.45 ± 4.92; permethrin, 1032.34 740.76; clothianidin, 3.61 1.48; imidacloprid, 73.32 47.52; thiamethoxam, 5.81 3.16; abamectin, 0.45 0.29; ivermectin, 8.88 5.06 ng/g). Honeybees sited always experienced mortality than those correspondingly upwind, male compared females when both downwind. Bees occurring 1 h 232–260% more likely die upwind. Thus, emitted from significant threats pollinators.
