Summary: This research examines the levels and trends of pollutants, specifically 17 congeners of PCDD/Fs and 12 dl-PCBs, in the air measured in the province of Gipuzkoa (Basque Country, Spain). The study found that the toxic equivalents (TEQs) for PCDD/Fs were 12.29 fg TEQm(-3) and for dl-PCBs were 1.63 fg TEQm(-3), which were in a similar range or lower than those observed in other national and international studies in industrial areas. The findings of this study can serve as an indicator of the potential impact of ERP on the health of the resident population and the environment.

Summary: Chlorine and bromine are highly reactive oxidizing elements with widespread industrial applications and a history of use as chemical weapons. Inhalation can lead to acute and chronic injury, with conditions such as viral infections, coexposure to other toxic gases, and pregnancy increasing susceptibility. Development of pharmacological agents post-exposure can decrease morbidity and mortality.

Summary: Bromide ions act as a catalyst to enhance the oxidation kinetics of thallium by chlorine in water treatment. The different species of thallium and bromine are kinetically relevant to the enhanced oxidation process. The knowledge of species-specific reactivity of thallium with bromine species can help predict thallium mobility in chlorinated waters containing bromide.

Summary: In this study, it was found that photochemical vapor generation of halides can be achieved in organic-acid-free media, with performance comparable to traditional scenarios using acetic acid. The role of copper acetate complexes in facilitating the generation of halides was highlighted. Gas chromatography-mass spectrometry was used to identify methyl halides as principal volatile compounds, and various intermediate species were confirmed using different analytical methods. The method's application in analyzing bottled water and seawater showed spike recoveries between 92 and 101%.

Summary: This study fabricated and characterized perovskite cells in standard mesoscopic architecture using a one-step deposition method. The impact of different halogen ions on crystal structure growth and photoelectric performance was investigated. The results showed that solar cells based on bromine had higher power conversion efficiency compared to those based on chlorine.

Summary: Conventional water treatment practices using chlorine as disinfectant may not effectively inactivate resistant pathogens such as Cryptosporidium parvum. This study evaluates the efficacy of free bromine as an alternative disinfectant and finds that at a concentration of 5 mg/L, bromine reduces C. parvum infectivity by 0.6 log compared to only 0.4 log by chlorine. It also demonstrates the effectiveness of bromine and chlorine in reducing Bacillus atrophaeus spores and MS2 coliphage by 4 log.

Summary: The rising sea level and seawater intrusion have caused an increase in bromide levels in coastal cities. Adding bromide improves the degradation of phenol, bisphenol A, and methylparaben by chlorine. The reactions between bromide, chlorine, and phenols are described by a kinetic model. The rate constants of active bromine with phenols are higher than those of chlorine, resulting in a bromide enhancement effect. The model accurately predicts the change in oxidant concentration over time. Developing techniques to remove bromide and phenolic components is important for controlling the formation of toxic brominated aromatic byproducts.

Summary: This study demonstrates that even the most volatile PCBs can maintain linear uptake in a passive air sampler using XAD-resin as the sorbent (XAD-PAS). The sampling rates for 66 congeners decrease with the number of chlorines and increase within a homologue with the number of chlorines in the ortho-position. By quantifying the effects of chlorine substitution and temperature on sampling rates, it is possible to estimate the sampling rates for all congeners at any deployment temperature. The XAD-PAS is suitable for unbiased sampling of gaseous PCBs in various settings.
