“…For the past 30 years, the notion of an Air Pollution Levels has been established and successfully employed throughout many industrialized countries to address the above problems. An Air Quality Index is a technique that combines the measured values of different contamination factors (SO2, CO, visibility, and so on) together into single value or a subset of figures (8). Throughout India, there have been several opportunities to improve and implement an Environmental Parameters, attributed to the fact that perhaps a minor air quality measurement scheme began only in 1984, and public understanding concerning polluted air would be almost non-existent (3).…”

Air Quality Index (AQI) technique has been used to analyze and gather database on pollution in the atmosphere. As air pollution is becoming a bigger threat with modernization, various countries are taking different measures to assess the amount of contamination present in the air we breathe. The current research has analyzed the impact of the pandemic on the air quality of Jodhpur and has compared AQI recorded monthly. Changes in the air quality were observed throughout the year 2020. Measurements for four sites in Jodhpur were compared and recorded. To measure the AQI of all the four, “Maximum Operator Function” method, initially tested in IIT Kanpur, was applied. Basni Industrial Area succeeded Shastri Circle and recorded the best air quality. Since both were categorized as industrial areas, it showed that policy measures relating to the industries in the city during past years have helped in improving the air quality.

“…Ez utóbbiak közül talán a szénmonoxidtól való félelem a legismertebb, a nyílt égésterű tökéletlen működésű kazánok és tűzterek (kandalló cserépkályha) miatt. A radon vagy a formaldehid mértéke és hatása sajnos egyelőre csak a kutatókat foglalkoztatja és a lakosság nagy része nincs tisztában a jelentőségükkel és hatásukkal (FRONTCZAK-WARGOCKI, 2011;GOYAL, 2012). Még kevésbé ismert és publikált az épületenergetikai jellemzők és a beltéri levegőminőség paraméterei között az ok-okozati összefüggések és kapcsolatok.…”

A koronavírus járvány megelőzésére hozott intézkedéseknek köszönhetően minden eddiginél többet töltöttünk zárt terekben, – például otthonainkban - mint korábban. Nem csak a levegőben terjedő Covid-19 vírus gyakorolt hatást szervezetünkre, hanem a természetes forrásokból származó ionizáló sugárzás, a bent tartózkodók légzéséből kialakuló magasabb széndioxid koncentráció vagy a tevékenységünkből (főzés, dohányzás, stb) levegőbe kerülő szennyező anyagok is. A bentlakók életvitelén kívül az épületek szerkezete, a beépített határolószerkezetek és az épületgépészeti egységek (hőenergia előállítás, szellőzés) határozzák meg a beltéri levegő minőségét. 2019 decemberében másféléves, Pest megye keleti részét érintő beltéri radonkoncentráció meghatározását célzó méréssorozatot indítottunk el 7 település 24 családiházának bevonásával. Eredményeink egyértelműen mutatják az évszakok közötti különbséget, de különbségek mutathatók ki a családiházak építészeti és épületgépészeti megoldásai között is.

“…Nanosized particles can be released into the breathing air by both exhaust [50,[60][61][62][63][64] and nonexhaust sources [60,62,[65][66][67][68]. These nanoscale particles undergo a number of physiochemical transformations [69,70], resulting in both spatial and temporal variation in their concentrations in both indoor [71][72][73][74] and outdoor [69,70,75] ambient environments. Nevertheless, it is still challenging to apportion the fraction of the ENMs in the total nanoscale particulate material present in the atmospheric environment [67].…”

The aim of this study is to identify current knowledge gaps in fate, exposure, and toxicity of engineered nanomaterials (ENMs), highlight research gaps, and suggest future research directions. Humans and other living organisms are exposed to ENMs during production or use of products containing them. To assess the hazards of ENMs, it is important to assess their physiochemical properties and try to relate them to any observed hazard. However, the full determination of these relationships is currently limited by the lack of empirical data. Moreover, most toxicity studies do not use realistic environmental exposure conditions for determining dose-response parameters, affecting the accurate estimation of health risks associated with the exposure to ENMs. Regulatory aspects of nanotechnology are still developing and are currently the subject of much debate. Synthesis of available studies suggests a number of open questions. These include (i) developing a combination of different analytical methods for determining ENM concentration, size, shape, surface properties, and morphology in different environmental media, (ii) conducting toxicity studies using environmentally relevant exposure conditions and obtaining data relevant to developing quantitative nanostructure-toxicity relationships (QNTR), and (iii) developing guidelines for regulating exposure of ENMs in the environment.
