Atmospheric ions originate from various natural and anthropogenic sources, their levels exhibit significant variations across diverse settings. These ion concentrations exert an influence on the overall count of aerosol particles in atmosphere, as well process new particle formation through ion-induced nucleation, ion-ion recombination, impact condensation growth. There is limited data available atmospheric rural regions Poland, there a complete absence publicly information concerning urban areas. Furthermore, lack knowledge about how these compare varying environments primary sources driving them.This study analyzes four-year shifts Poland's concentrations, uncovering implications. Amid changing agricultural practices, environmental factors, socio-economic developments, monitoring alterations crucial for assessing impacts ecosystems human health. This conducts thorough examination air, utilizing measured by GIOŚ at five different locations Poland. The aim to investigate patterns trends with particular focus such Ca²⁺, Cl⁻, K⁺, Mg²⁺, Na⁺, NH₄⁺, NO₃⁻ SO₄²⁻.

Firefighters’ occupational activity causes cancer, and the characterization of exposure during firefighting activities remains limited. This work characterizes, for first time, firefighters’ to (coarse/fine/ultrafine) particulate matter (PM) bound polycyclic aromatic hydrocarbons (PAHs) metal(loid)s prescribed fires, Fire 1 2 (210 min). An impactor collected 14 PM fractions, levels were determined by gravimetry, PM-bound PAHs chromatographic spectroscopic methodologies, respectively. Firefighters exposed a total level 1408.3 342.5 µg/m3 in 2, respectively; fine/ultrafine represented more than 90% PM. Total (3260.2 ng/m3 1; 412.1 2) (660.8 versus 262.2 ng/m3), distributed between PM, contained 4.57–24.5% 11.7–12.6% (possible/probable) carcinogenic metal(loid)s, PAHs, below available limits. The estimated risks associated with inhalation (3.78 × 10−9 − 1.74 10−6) (1.50 10−2 2.37 10−2) were, respectively, 150–237 times higher acceptable risk defined USEPA 210 min assuming 40-year career as firefighter. Additional studies need (1) explore (2) assess health risks, (3) identify intervention needs, (4) support regulatory agencies recommending mitigation procedures reduce impact fire effluents on firefighters.

Despite the long-term implementation of air pollution control policies in northeast China, severe haze continues to occur frequently. With adoption a megacity (Changchun) we analysed vertical characteristics aerosols and causes aerosol throughout year using multisource data for providing recommendations controlling events (i.e., straw burning fireworks). Based on ground-based LiDAR, it was found that extinction coefficient (EC) at height 300 m Changchun highest winter (0.44 km−1), followed by summer (0.28 with significant differences from those warmer regions, such as Yangtze River Delta. Therefore, is recommended be differentiated between summer. On Chinese New Year’s Eve Changchun, ignition firecrackers during day night caused increases EC 500 0.37 0.88 km−1, respectively. It suggested regulation firecracker should reduced strengthened night. CALIPSO backward trajectory analysis results, two dust–biomass-burning composite were observed March April. In March, primary component dust western whereas April, main biomass-burning originating northern eastern Changchun. Hence, reducing intensity spring biomass can mitigate occurrence pollution. These findings provide emission policy suggestions areas facing similar issues regarding transmission firework emissions.

Global energy scenario is becoming vital for the sustainable economic development of a region or country. Current changes in production, mainly due to scarcity and geopolitical factors, have proven need mix towards lower dependence. In that sense, considerable amount biomass waste generated many regions, because agro-industrial activities, whose management could contribute production. The aim this work was study determination combustion conditions stove by using different raw materials as fuels, such pine, poplar, plum tree pellets. For purpose, power, excess air, content were optimized, among other parameters, fumes analyzed with Testo 335 analyzer, recording temperatures temperature probes. As conclusion, high yields found optimized parameters studied (ranging from 91.1 % poplar pellet 92.34 pine pellet), making these three fuels suitable abovementioned stove.
