Short And Long Term

Mosses are one of the best bioindicators in the assessment of atmospheric aerosol pollution by heavy metals. Studies using mosses allow both short- and long-term air quality monitoring. The increasing contamination of the environment (including air) is causing a search for new, cheap and effective methods of monitoring its condition. Once such method is the use of mosses in active biomonitoring. The aim of the study was to assess the atmospheric aerosol pollution with selected heavy metals (Ni, Cu, Zn, Cd, Hg and Pb) from the smoke of fireworks used during New Year’s Eve in the years 2019/2020 and 2020/2021. In studies a biomonitoring moss-bag method with moss Pleurozium schreberi (Willd. ex Brid.) Mitt. genus Pleurozium was used. The research was conducted in the town Prószków (5 km in south direction from Opole, opolskie voivodship, Poland). The moss was exposed 14 days before 31 December (from 17 to 30 of December), on New Year’s Eve (31 December and 1 January) and 2 weeks after the New Year (from 2–15 January). Higher concentrations of analysed elements were determined in samples exposed during New Year’s Eve. Increases in concentrations were demonstrated by analysis of the Relative Accumulation Factor (RAF). The results indicate that the use of fireworks during New Year’s Eve causes an increase in air pollution with heavy metals. In addition, it was shown that the COVID-19 induced restrictions during New Year’s Eve 2020 resulted in a reduction of heavy metal content in moss samples and thus in lower atmospheric aerosol pollution with these analytes. The study confirmed moss usefulness in monitoring of atmospheric aerosol pollution from point sources.

Accumulation of heavy metals in fish is considered a critical problem for human health. Therefore, the study aimed to quantify the concentrations of iron (Fe), zinc (Zn), manganese (Mn), and lead (Pb) in Oreochromis niloticus and Clarias gariepinus from two areas in Al Sharqia governorate, Egypt, from September 2017 to August 2018. A human health risk assessment was conducted to evaluate the potential hazards associated with fish consumption. Metals concentrations (mg/kg dry weight) in muscles of catfish ranged 1.88-221.26 for Fe; 1.78-19.77 for Zn; BDL-238.51 for Mn; BDL-22.75 for Pb. In muscles of tilapia fish metals concentrations ranged 7.96-149.10 for Fe; 1.20-19.77 for Zn; BDL-230.82 for Mn; BDL-25.93 for Pb. Pb had Hazard quotients (HQs) which indicated potential health risks to tilapia consumers at both study areas and catfish consumers at the Faqous area. Fishermen were at higher risk compared to the other consumers.

City growth often time results in advancement and development in transportation which comes with its attendant changes in road infrastructure and transport support services such as road side mechanic workshops, vulcanizers and bus stops. A byproduct of these attendant contiguous activities and processes is the emission and release of trace heavy metals. Trace heavy metals have been identified as major carcinogens. This study aimed at determining the occurrence and concentration of heavy metals in roadside soils in an expanding third world metropolis. To achieve the aim of the research, the total length of the road within the study section was measured. Ten sample locations were indentified at about 2.5km intervals along the road section under review. The heavy metal concentration was determined the using Buck Scientific 210 VGP Atomic Absorption Spectrophotometer. Heavy metals such as Iron (Fe), Copper (Cu), Cadmium (Cd), Lead (Pb) and Mercury (Hg) were determined. The result of the analysis showed that the concentration values ranged from <0.001 to 48.90 µg/mg. The results also revealed that the experimental sample points recorded higher values than the control samples; however, some of the control points had relatively higher concentration values. This observation may have emanated from the low lying trajectory and topography of the surrounding area, which allows run-off from the road side soils to wash off heavy metals and deposit them at these lower lying areas. The sources of these trace heavy metals are attributed to emissions from motor vehicles that ply the road on a day to day basis. Emanating from the findings, this study recommends that improved public transportation and cleaner sources of energy is recommended.
