03/02631 Effects of increased biomass pellet combustion on ambient air quality in residential areas — a parametric dispersion modeling study

The monitoring of ambient air quality of Katra (one of the important town of Jammu from economic as well as religious point of view), at selected locations of residential areas, commercial areas and traffic crossings with respect to particulate matter (both respirable and non-respirable) has been conducted for a period of two years i.e. July 2010 – June 2012. Large variations in ambient particulate matter concentrations have been observed throughout the study period. Seasonally, the particulate matter exhibited low values during monsoon period and high values during post-monsoon period. The concentration of particulates (both respirable and non-respirable) in post monsoon season exceeded the concentrations than that of other seasons at most of the sites, thereby signifying the impact of local factors on pollutant concentrations, besides the impact of meteorological factors. Higher concentrations have been recorded in the year 2011-2012 as compared to 2010-2011 at all the sites except traffic crossings.

<div><table cellspacing="0" cellpadding="0"><tbody><tr><td align="left" valign="top"><p><em>The construction of toll roads has a positive impact to facilitate the mobility rate of the community. But the construction of toll roads also has a negative impact on the residential area around the toll road, namely air pollution due to the burning of vehicle fuel. PM2.5 and PM10 air particles are particles that damage the working system of the lungs. The health of the environment where settled is an important support that affects health, especially in the era of pandemic covid. Air particle measurement using portable PM2.5 and PM10 Air Quality Tester Detector. The daily average level of PM2.5 particles in residential areas around Semarang's Kedungmundu toll road is 65.44 μg/Nm³, while the PM10 particle content is 95.2 μg/Nm³. PM2.5 levels exceed the standards of the National Ambient Air Quality Standard (BMUA), The WHO Air Quality Guidline and Ambient Air Quality Standards (USEPA). For PM10 exceeds WHO standard. In addition to air pollution, another impact is that these residential areas have noise. The daily average noise value when measuring the sampling time is 62.23 dB, this value is exceeding the standard threshold of the Regulation of the Minister of Environment for residential areas. So the residential area around Kedungmundu Semarang toll road is less feasible for health when viewed from the value of PM 2.5 and PM10 as well as noise. This study aims to determine the level of PM2.5 and PM10 particles as well as noise in residential areas around the Kedungmundu Semarang toll road. Once the measurement results are obtained, it will be used as a reference for planners to provide solutions for settlements that have an impact due to toll road construction activities with dense vehicle intensity.</em></p></td></tr></tbody></table></div>

The Impact

Ambient air in the urban area normally is more polluted than less developed areas. This is due to the concentration of urban activities, such as industrial, transportations and commercial or business activities. A study about the impact of urban land uses and activities on the levels of air pollutants in Malaysia’s most urbanised and most developed region that is Klang Valley was conducted. Data of Air Pollutant Index (API) and average concentration of selected air pollutants were used to analyse the ambient air quality of the selected five (5) cities or towns in Klang Valley. The air quality condition of the five (5) cities or towns were related to the land use distributions of the cities or towns with a purpose to understand the impact of land uses on the ambient air quality. Furthermore, the changes of ambient air quality before and after Movement Control Order (MCO) were analysed to examine the impact of human activity changes on the ambient air quality. The study found that a city or a town with more industrial and transportation land uses with fewer greens was more polluted than the area with less industrial and transportation land uses with more greens. However, this finding did not apply to all areas due to effect of winds on the distribution of air pollutants. Besides that, because of MCO, most people stayed at home with the mode of “work from home” that caused air pollutant levels in urban areas to decrease due to less urban activities. Nevertheless, there was a risk of an increase in air pollution levels in residential areas due to the concentration of activities, especially driving motor vehicles in residential areas. A recommendation is given to encourage “work from home” and reduce dependency on auto-mobile in residential areas in order to improve the air quality in urban areas.

Introduction: The article is devoted to poor ambient air quality in some cities of the Russian Federation, one the most important social and environmental issues of today. The city of Chita is a priority area in term of ambient air pollution included in the Federal Clean Air Project of the National Ecology Project. Our objective was to assess air quality in residential areas of the city for a further improvement of the ambient air quality monitoring system and air quality action planning. Materials and methods: We analyzed the results of measuring ambient air quality at the monitoring sites of the government environmental monitoring system for 2014–2018 and statistical data on the volume and composition of industrial emissions. The spatial analysis of the impact of enterprises on residential areas was carried out in accordance with the guidelines of the Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing (Rospotrebnadzor). Results and discussion: We established high concentrations of benzo(a)pyrene (up to a 10.5-fold excess of the average daily maximum permissible concentration (MPC)), particulate matter (up to a 1.63-fold excess of the average daily MPC and a 11.4-fold excess of the single MPC), nitrogen dioxide (up to a 1.18-fold excess of the average daily MPC), hydrogen sulfide (up to a 11.94-fold excess of the single MPC), phenol, soot, and some other hazardous air contaminants. We determined priority sources of anthropogenic emissions and other factors contributing to poor air quality in Chita. Conclusions: Our findings indicate the necessity to enhance the existing ambient air quality monitoring network and programs, to assess spatial distribution of resulting exposure levels and population health risks, and to decide on the adequacy of the air quality action planning in the city of Chita in accordance with the comprehensive plan.

Road Junctions

An evaluation of the ambient air quality of emitted gases and particles at major road junctions within Warri conurbation was carried out. The study was aimed at ascertaining if air pollution levels exceeded the acceptable limits during weekdays as well as attempt to target the root causes. Ambient air was monitored from strategic locations at eight major road junctions sparsely distributed within residential areas for in-situ measurement of NO2, SO2, CO and PM10 concentrations. Monitoring was done consecutively for a period of two weeks at four single-carriage and four dual-carriage roads to test the contributions of traffic on air quality. The averages of the minimum and the maximum daily observations over the entire sampling period ranged between 0.02452ppm and 0.05684ppm for NO2, while that of SO2 ranged between 0.00564ppm and 0.05654ppm, and that of CO ranged between 0.438ppm and 4.890ppm, whereas PM10 yielded 13.602μg/m3 as minimum and 122.124μg/m3 as maximum levels. As was expected, concentrations from all the single carriage roads were higher than those from the dual carriage roads owing to the heavy traffic congestions in single-lane roads. This study also revealed that only the NO2 values obtained around Robinson plaza and Warri main market junctions were perilously close to the specified FMENV levels for hourly exposure. This being that there were rapid oxidation of NO to NO2 from vehicular emissions. However, the presence of high levels of NO2 is synonymous to high ground level ozone production environment, consequently, a high oxidation region of free radicals which could lead to more particulate matter formation during advection.

Ambient Air Quality Standards

The Clean Air Act Amendments of 1970 provide the basis for a dramatic change in Federal air quality programs. The Act establishes new standards for motor vehicles and requires EPA to establish national ambient air quality standards, standards of performance for new stationary sources of pollution, and standards for stationary sources emitting hazardous substances. Further, it establishes procedures which allow states to set emission standards for existing sources in order to achieve national ambient air quality standards. The Act also permits the Administrator of EPA to register fuels and fuel additives and to regulate the use of motor vehicle fuels or fuel additives which pose a hazard to public health or welfare.National air quality standards for particulate matter have been established. Asbestos, mercury, and beryllium have been designated as hazardous air pollutants for which Federal emission standards have been proposed.
