Urban gardening has become more and popular in recent years, as people might prefer to grow their own vegetables from controlled sources. In addition, community building also plays a key role. However, air pollution settlements is serious hazard affecting the quality of home-grown vegetables. During vegetation period, traffic main factor generating atmospheric particulate matter. These particles will, turn, bind potentially toxic compounds, which heavy metals polycyclic aromatic hydrocarbons (PAHs) are most widely studied discussed. addition potential toxicity, both groups contain carcinogenic species. Heavy metals, well PAHs, capable bioaccumulation, depending on element or compound’s characteristics vegetable Some leafy can accumulate these materials significant quantities. As dietary uptake considered major exposure route consumption impacted even pose human health risks. This review summarises available data reported metal PAH accumulation urban environments, specified by Also, assessment possible impact given.

As part of the Zero Pollution Action Plan Green Deal, European Commission has set goal reducing number premature deaths caused by fine particulate matter (PM2.5) at least 55% 2030, compared to 2005 levels. To achieve this, aims introduce stricter limits. In urban areas, road transport is a significant source PM emissions. Vehicle originates from engine exhaust and tire, brake wear, as well dust resuspension. recent decades, application stringent emission limits on vehicle led adoption technologies capable strongly emissions tailpipe. Further, progressive electrification fleets will lead near-zero On other hand, non-exhaust have increased in years following proliferation sport utility vehicles (SUVs), whose numbers jumped nearly tenfold globally, electric vehicles, these tend be heavier than corresponding conventional older internal combustion light-duty vehicles. This shift resulted more modest reduction PM10 PM2.5 sector pollutants (−49% −55%, respectively, 1990 2020). report provide an up-to-date overview characterization, drawing insights scientific literature address this critical environmental public health challenge.

This contribution deals with the assessment of air pollution caused by atmospheric aerosol particulate matter fraction PM10 and benzo[a]pyrene (BaP) in urban agglomeration Ostrava, located Czech Republic Central Europe. The motivation for this research was need to identify sources area, particularly locations where different concentrations pollutants concern has not been elucidated yet. In study, source apportionment vicinity industrial hot-spot performed statistically evaluating measured pollutant as a function meteorological variables using Positive Matrix Factorization (PMF) receptor model. A significant methodological innovation improvement over previous assessments higher monitoring resolution benzo[a]pyrene, samples collected at three-hour intervals instead standard 24-hour collection period. key findings indicate that cold part year, secondary particles - specifically sulphates ammonium nitrates were responsible most portion throughout area interest. these ranged from one third two fifths total concentration, except site Ostrava-Radvanice (TORE), they accounted approximately fifth concentration level.

Abstract Road dust resuspension in urban environments can contribute to high human exposure metal(loid)s, polycyclic aromatic hydrocarbons, and other potentially toxic organic compounds. However, for many regions, information on loadings, emission factors chemical profiles is lacking accurately apply inventories source apportionment models. In the present study, PM 10 samples were collected with an situ road sampler from eleven representative streets of Bragança, inland city Iberian Peninsula, analysed elemental carbon by a thermal-optical technique, composition ICP-MS ICP-OES, ecotoxicity luminescence inhibition bioassay Allivibrio fischeri . A global factor 5.36 ± 2.35 mg veh −1 km was obtained but suburban areas values reached twice average. Total accounted 14.9 6.8% mass, while element oxides represented largest share (28.6 18.7%). Very enrichments found typical traffic-related elements such as Cu, Zn, S, Pb Ni. The geochemical index I geo further confirmed that study region extremely contaminated mainly originated tyre brake wear. Although total non-carcinogenic carcinogenic risks associated metal be low both children adults, bioluminescence assay showed (eco)toxic responses all samples, indicating may pose significant health ecological threat.

While car exhaust emissions in the EU are clearly decreasing, future of non-exhaust looks more pessimistic. The relative importance latter is thus expected to increase terms air quality and human health. aim study was assess regional seasonal differences chemical composition road dust across Czech Republic health impact its resuspension, with special respect polycyclic aromatic hydrocarbons metals. samples all regions seasons were collected. Based on subsequent laboratory statistical processing, spatiotemporal distribution elements PAHs evaluated. Next, contribution resuspension concentrations estimated related impacts assessed. A significant variations metals discovered. Air quality, leading atmospheric deposition, most important factor contributing these variations. In contrast, traffic intensity played only a minor role influencing dust. Exposure PM
