“…A total of 150 isolates were collected randomly from different areas in Samawa City during the period from November 2014-February 2015. Our results include (100) isolates from indoor ,(79) of them were positive in the growth culture while (11) were negative (with percentage 79%).The outdoor isolates were (50), (14) were negative in the growth culture and (36) isolates were positive (with percentage 72%). In the indoor isolated bacterial species K. pneumoniae was the commonest pathogen (36.70%) followed by S. aureus (1.26%) respectively (Fig.…”

“…According to a study by Rudan et al [13] reported that K. pneumoniae and Staphylococcus aureus were the most responsible cause of severe cases of pneumonia among children aged under 5 years, and Since the individuals spend most of their time in the indoor environments compared to the outdoors as mentioned by Lebowitz [14], So we focused on K. pneumoniae in this study for this reason since it comprises the majority of indoor pathogens.…”

"Dust includes many microorganisms such as airborne bacteria. Most types of these bacteria are harmful to humans and causing severe problems. Klebsiella pneumoniae considered as serious nosocomial pathogen that cause pneumonia, UTIs, wound and liver abscesses. One hundred fifty samples isolated randomly from different indoor and outdoor areas during the period November 2014- February 2015. In the indoor isolates bacterium K. pneumoniae was the commonest pathogen (36.70%) followed by S. aureus (22.78%), S. epidermidis (12.65%), Bacillus spp. (10.12%), P. aeruginosa (5.06%), E. cloacae (5.06%), Streptococcus spp.(2.53%), Citrobacter spp.(1.26%) and Pantoea spp.(1.26%). While S. aureus comprises the majority of outdoor bacteria in (41.66%). Using PCR method for detection of Uge gene and followed with direct DNA Sequencing. The multiple sequence alignment (MSA) showed highly conserved area in all studied strains. However, some variants were observed at different positions (24, 124, 152, 163, 165, 185, 199, 200, 207, 209, 248, 279, 284, 291). Also there were changes in a functional whole areas at the studied gene such as (GGCTGG) at the positions (212-217), (ATCCCG) at positions (226-231), (GCCC) at (233-236), (ACCG) at positions (242-245), (GATT) at (263-266), (TCAA) at (269-272). These differences in the gene sequence may indicates special characterizations for the isolated strain."

“…In the modern urban setting, most individuals spend about 80% of their time indoors and are therefore exposed to the indoor environment to a much greater extent than to the outdoors (Lebowitz 1992). Concomitant with this increased habitation in urban buildings, there have been numerous reports of adverse health effects related to IAQ ("sick buildings").…”

“…As per the Central Pollution Control Board (CPCB), New Delhi, India, the concentration of NO 2 and particulate matter (PM 10 ) in the air have exceeded their prescribed limits [9,35]. These pollutants not only alter the ecological balance but also degrades the indoor air quality (IAQ) associated with building structures in urban areas [21]. As a result, several health issues like pulmonary and respiratory disorders were observed, and approximately 500,000 cases were reported every year in India [31].…”

Ti doped BaMnO3 perovskite structure as photocatalytic agent for the degradation of noxious air and water pollutants

et al. 2020

Photocatalytic degradation of noxious water and air impurities like Methylene blue (MB), Rhodamine B (RhB), NO x-, and CO is carried out by pristine and Ti-doped BaMnO 3 (BaMn 0.85 Ti 0.15 O 2.93 , BMT). Perovskite BMT ceramic mixed with equimolar ratio of zeolite is used for investigation of water and air pollutant degradation. The synthesized Ti-doped BaMnO 3 (BaMn 0.85 Ti 0.15 O 2.93 , BMT) perovskite was characterized using X-ray diffraction (XRD) and FE-SEM techniques. The XRD pattern of Ti-doped BaMnO 3 shows the formation of two phases, namely BaMnO 2.92 and BaMn 0.85 Ti 0.15 O 2.93 and BMT. The photocatalytic degradation of noxious water and air pollutants were analyzed using UV-Vis and XPS for doped and pristine BaMnO 3 . From obtained results, it is observed that the synthesized BMT shows enhanced photocatalytic degradation (~ 99%) as compared to BaMnO 3 toward noxious water impurities like RhB and MB dyes within 270 and 150 min under sunlight. The synthesized BMT compound shows the absorbance spectrum in the wavelength range of 200-600 nm. The UV-Vis DRS confirms the absorption edges for the compound above 400 nm i.e., visible light absorber with a bandgap 2.48 eV. On the other hand, XPS analysis of bulk BMT-zeolite on exposure to sunlight shows the complete degradation of adsorbed NO x gases from the BMT-zeolite surface as compared to the unexposed zeolite sample surface. Therefore, BMT can be used as active photocatalytic agent for the remediation of environmental noxious water and air pollutants.
