This document discusses using a hybrid machine learning technique combining differential evolution and random forest methods to predict air pollution levels. It analyzes data on various pollutants from two cities in India - Delhi and Patna. The proposed approach is experimentally validated to achieve better performance compared to independent classifiers and multi-label classifiers in terms of accuracy, area under the curve, success index and correlation. Differential evolution is used to initialize population and optimize candidate solutions. Random forest creates an ensemble of decision trees to make predictions. The hybrid method is tested on predicting carbon monoxide, nitrogen dioxide and benzene levels using data from a monitoring station in Delhi.
Reflections on diesel exposures in professional drivers - a poorly quantified...IES / IAQM
This document summarizes research on diesel exhaust exposures among professional drivers. It discusses several studies that have found high exposures and health effects among drivers such as taxi, truck, and bus drivers. The document outlines a new study called DEMiSt that aims to better characterize exposures for 200 drivers across sectors and identify strategies to reduce risks. Preliminary results suggest taxi drivers have the highest exposures while ventilation settings significantly impact levels. Reducing "pollution spikes" may substantially lower exposure. The study also examines exposures between electric and diesel taxis.
An environmental impact assessment was conducted for a proposed integrated steel plant in Odisha, India. The summary finds:
1) Ambient air quality monitoring found existing PM10 and PM2.5 levels above national standards in the project area. Dispersion modeling also predicted the plant would significantly increase air pollution.
2) The EIA report underestimated health impacts by missing secondary particulate formation and incremental PM2.5 impacts. It also did not account for mercury or heavy metal emissions.
3) Based on estimated annual emissions of 9433 tons of PM, 13,131 tons of NOx, and 11,642 tons of SO2, a health impact assessment was conducted and found significant impacts from increased
The document discusses the health impacts of particulate matter (PM2.5) air pollution. It notes that exposure to anthropogenic PM2.5 leads to reduced life expectancy, with models showing losses ranging from months to over a year depending on the year and meteorological factors. Motor vehicles are identified as major contributors to air pollution in cities, responsible for around half of particulate emissions. Long term exposure to elevated levels of PM2.5 and other air pollutants increases mortality rates from respiratory and cardiac causes.
SIMULATION OF ATMOSPHERIC POLLUTANTS DISPERSION IN AN URBAN ENVIRONMENTAM Publications
Interest in air pollution investigation of urban environment due to existence of industrial and commercial activities along with vehicular emission and existence of buildings and streets which setup natural barrier for pollutant dispersion in the urban environment has increased. The air pollution modelling is a multidisciplinary subject when the entire cities are taken under consideration where urban planning and geometries are complex which needs a large software packages to be developed like Operational Street Pollution Model (OSPM), California Line Source model (CALINE series) etc. On overviewing various works it can be summarized that the air pollutant dispersion in urban street canyons and all linked phenomenon such as wind flow, pollutant concentrations, temperature distribution etc. generally depend on wind speed and direction, building heights and density, road width, source and intensity of air pollution, meteorological variables like temperature, humidity etc. A unique and surprising case is observed every time on numerous combinations of these factors. The main aim of this study is to simulate the atmospheric pollutant dispersion for given pollutant like carbon monoxide, sulphur dioxide and nitrogen dioxide and given atmospheric conditions like wind speed and direction. Computational Fluid Dynamics (CFD) simulation for analysing the atmospheric pollutant dispersion is done after natural airflow analysis. Volume rendering is done for variables such as phase 2 volume fraction and velocity with resolution as 250 pixels per inch and transparency as 20%. It can be observed that all the three pollutant namely nitrogen dioxide, sulphur dioxide and carbon monoxide the phase 2 volume fraction changes from 0 to 1. The wind velocity changes from 3.395×10-13 m/s to 1.692×102 m/s. The dispersion of pollutants follow the sequence Sulphur dioxide>Carbon monoxide>Nitrogen dioxide.
This study investigated spatial patterns of air pollution in an industrial estate in Lagos, Nigeria. Seven sampling sites were selected to measure levels of particulate matter (PM10), sulfur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO), hydrogen sulfide (H2S), methane (CH4), and noise. Statistical analysis using principal component analysis and cluster analysis revealed two main sources of air pollution: traffic emissions contributed most to NO2 levels, while fossil fuel combustion and industrial sources contributed most to SO2, CO, and H2S levels. The levels of SO2, NO2, and PM10 exceeded national standards at some sites, indicating traffic and industrial pollution are problems. Appropriate vehicle emission controls

Air pollution is the introduction of chemicals or other materials into the atmosphere that can harm humans or the environment. It occurs naturally, such as from volcanoes, or is man-made through processes like fuel combustion from vehicles, factories, and power plants. Air pollutants can be classified as primary emissions or secondary pollutants formed when primary ones react in the air. Air pollution is a major global health risk and causes many respiratory and heart conditions, as well as lung cancer and early death. Efforts to reduce pollution include using cleaner fuels in vehicles and industry and installing pollution control devices.
- Air pollution causes over 13,000 premature deaths per year in South Korea. Fine particulate matter (PM2.5) is the main culprit, responsible for over 12,000 deaths from lung cancer, heart disease, and stroke.
- The South Korean government has invested billions to reduce emissions from diesel vehicles and install filters, but air quality has worsened since 2013. Meteorological conditions are also playing a role, with weaker winds leading to increased air stagnation.
- South Korea has launched a National Strategic Research Project with four goals: evaluating pollution sources, improving forecasting, strengthening emissions controls, and reducing population exposure.

Air pollution is most important from the public health of view, because every individual person breaths approximately 22000 times a day, inhaling about 15 to 22 kg of air daily. The main pollutants contribute by automobile are carbon monoxide (CO), unburned hydrocarbon (UBHC), oxides of nitrogen (NOx) and Lead. Pollutant removal from combustion gas in both SI&CI is one of the most widely known environmental applications of activated carbons. In order to guarantee the successful removal of contaminants and pollutants on activated carbons, the developments of new adsorbents has been increasing in the last few years. This paper is a systematic study of cleaning SI&CI engine of CO, SO2, NO2 Using activated carbon filter. The combustion gases were qualitative and quantitative analyzed by gas chromatography. The use of this simple method is a valuable alternative to meet emission standards in developing countries. It was demonstrated that the agricultural wastes studied here are a feasible alternative for reducing pollutants in SI & CI engine.
A new method of assessment and equations on Carbon footprintiosrjce
Carbon footprint or green terminology has become famous over a few decades in many countries
including India. Several industrial development schemes and policies are developed and are developing which
broadly focuses on green terminology [1, 2]. Although the terms such as carbon footprint, ecological footprint
and green terminology are much popular, there exists no standard ideology or a theory accepted so far which
would be used worldwide and thereby ends this long lasting debate. This article focuses on a new theory
developed in order to minimize the problems, uncertainties and errors related to the previous studies and to
attain precise completeness to the assessment with the help of equations which would also lead further research
and development in the field.
This document is a thesis submitted by Tamas Benko to the Budapest University of Technology and Economics for the degree of Doctor of Philosophy in Chemical Engineering. The thesis investigates the applicability of Life Cycle Assessment (LCA) in process engineering to support environmentally-conscious decision making. It examines LCIA methods and their uncertainties, applies LCA to analyze air pollution and waste solvent treatment options, and demonstrates that LCA can help integrate environmental considerations into process design. The research aims to show how numerical LCA tools using single score impact indicators can evaluate alternative technical solutions and determine optimal operational parameters to minimize environmental impacts.
The study assessed the indoor air quality of an office at St. George's University using an indoor air quality meter. Measurements found temperature and particulate matter levels to be within guidelines, while relative humidity was above guidelines at 59.4-75.9% RH. Carbon dioxide levels indicated adequate ventilation but total volatile organic compound levels ranged from 403-3859 ppb, in the "multifactorial exposure range" that may cause discomfort with other factors. Overall indoor air quality was acceptable except for elevated relative humidity that could contribute to thermal discomfort reported by occupants.
The Effects of Electronic Waste Burning on Lead Concentration in Water and Bl...Premier Publishers
The burning of electronic waste constitutes a major public health problem in South west Hebron -Southern Hebron Governorate – in which electronic waste burning is prevalent. This descriptive comparative study aimed to investigate the effect of electronic waste burning on the concentrations of lead in human blood and water samples (n=104) in South west Hebron as an exposed region with the town of Halhul as a control. Results showed that 39% and 55% of participants supported that electronic waste burning has an impact on municipal and natural resource’s water. Moreover, 69% did not think that burning affects the taste of water, while 72.2% did not think that such burning affects the smell of water. Water and blood samples from exposed regions had higher lead concentrations level than those not exposed with mean of (3.30PPb versus. 2,74PPb) and (46.34PPb versus. 31.6PPb) respectively. Electronic waste burners had a higher lead concentration (55PPb) than those not burning (39PPb). However, hemoglobin level was higher among none exposed (12.19PPb) than exposed (11.28PPb) regions. The burning of electronic waste affects both health and environment. Therefore, upgrading knowledge and education about the damages and impact of burning of electronic waste on human health are considered the first step in overcoming this problem.

Utilization of agro-waste for removal of toxic hexavalent chromium: surface i...Ratnakaram Venkata Nadh
Abundantly available agricultural waste materials
(banana bunch, sorghum stem and casuarinas fruit) are
processed with negligible cost and are found to be highly
suitable as biosorbents for chromium(VI) removal from
aqueous environment due to high surface area and functional
groups of adsorbents. The equilibrium data have
been analyzed for the adsorbate–adsorbate/adsorbent
interactions and found to be fitted to the data in the order,
Hill–de Boer C Fowler–Guggenheim % Frumkin[Kiselev.
To determine the characteristic parameters for process
design, mass transfer studies have been carried out using
two-parameter isotherm models (Harkins–Jura, Halsey,
Smith, El-Awady and Flory–Huggins) and three-parameter
isotherm models (Redlich–Peterson and Sips) which are
applied to the experimental data. The fitness of the isotherms
describes that both mono- and multilayer adsorptions
occur in the present studied three biosorbents in
preference to the latter. The mechanism of adsorption has
been studied using diffusion kinetic models (viz. liquid film
diffusion, Dunwald–Wagner intra-particle diffusion model
and moving boundary model) and described the possibility
of diffusion in the order of banana bunch–stem powder[
sorghum stem powder[casuarinas fruit powder in
terms of diffusion coefficients. In essence of all the results,
the selected adsorbents can be used as a potential adsorbent
for the removal of Cr(VI) from aqueous solutions.

Assessment of Variation in Concentration of Air Pollutants Within Monitoring ...IRJET Journal
This document summarizes a study that assessed variation in air pollutant concentration across 12 monitoring stations in Mumbai, India. The study analyzed monthly pollution data from 2020-2021 for 7 pollutants (PM2.5, PM10, NO2, NH3, SO2, CO, ozone) from the Central Pollution Control Board. Statistical analysis using ANOVA and Tukey's HSD post-hoc test identified pairs of stations without significant differences in pollutant concentrations across all 7 pollutants. This analysis could help identify redundant monitoring stations. The study also used logistic regression to predict air quality class based on factors like tree cover, population density, temperature, and more.
IRJET - Air Quality Index – A Study to Assess the Air QualityIRJET Journal
This document discusses a study on assessing air quality in Delhi, India using the Air Quality Index (AQI). It provides background on air pollution and the importance of measuring AQI. The study calculates daily AQI values over three years for Delhi based on concentrations of pollutants like NO2, SO2, SPM and RSPM. The results show AQI values were regularly unhealthy around 200. SPM and RSPM correlated most strongly with AQI, suggesting they are major contributors to air pollution. Stricter measures are needed to address rising levels of particulate matter and improve air quality.

processed with negligible cost and are found to be highly
suitable as biosorbents for chromium(VI) removal from
aqueous environment due to high surface area and functional
groups of adsorbents. The equilibrium data have
been analyzed for the adsorbate–adsorbate/adsorbent
interactions and found to be fitted to the data in the order,
Hill–de Boer C Fowler–Guggenheim % Frumkin[Kiselev.
To determine the characteristic parameters for process
design, mass transfer studies have been carried out using
two-parameter isotherm models (Harkins–Jura, Halsey,
Smith, El-Awady and Flory–Huggins) and three-parameter
isotherm models (Redlich–Peterson and Sips) which are
applied to the experimental data. The fitness of the isotherms
describes that both mono- and multilayer adsorptions
occur in the present studied three biosorbents in
preference to the latter. The mechanism of adsorption has
been studied using diffusion kinetic models (viz. liquid film
diffusion, Dunwald–Wagner intra-particle diffusion model
and moving boundary model) and described the possibility
of diffusion in the order of banana bunch–stem powder[
sorghum stem powder[casuarinas fruit powder in
terms of diffusion coefficients. In essence of all the results,
the selected adsorbents can be used as a potential adsorbent
for the removal of Cr(VI) from aqueous solutions.

Urban Air Quality Modelling and Simulation: A Case Study of Kolhapur (M.S.), ...IDES Editor
As a consequence of urbanization a phenomenal
surge has been observed in the vehicular population in India,
giving rise to elevated levels of traffic related pollutants like
carbon monoxide, nitrogen oxides, hydrocarbons, and
particulates in Indian urban centers. These pollutants can
have both acute and chronic effects on human health. Thus
air quality management needs immediate attention. Air
quality models simulate the physical and chemical processes
occurring in the atmosphere to estimate the atmospheric
pollutant concentration. A variety of air quality models are
available ranging from simple empirical models to complex
Computational Fluid Dynamic (CFD) models. Air quality
models can be a valuable tool in pollution forecasting, air
quality management, traffic management and urban planning.
This paper evaluates the performance of widely used Danish
Operational Street Pollution Model (OSPM) under Indian
traffic conditions. Comparison between predicted and observed
concentrations was performed using both quantitative and
statistical methods. OSPM was found to perform exceedingly
well for the prediction of particulates whereas NO2 predictions
were poorly predicted.
An Analytical Survey on Prediction of Air Quality Indexijtsrd
A drastic increase of modernization gives birth to many industries and automobiles, which intern becomes the very common reason for the environmental issues like Air and water pollutions. Air pollution is the immediate affecting factors in our life, which contaminates the air that we breathe to cause serious health hazards. So it is very important to predict the Air quality index for the future coming days so that proper prompt action can be taken by the concern authorities to curb the same. The air quality reading for the different gases can be collect through the physical sensors and these readings can be used to predict the future Air quality index. Machine learning is acting as the catalyst in this prediction scenario to predict the accurate Air quality index for the future instance. Most of the learning systems need a huge amount of the data for the learning purpose and it is not possible to provide this every time. So it is a need to predict the air quality index by using considerable less amount of past instance data, This paper mainly concentrates on analyzing the past work in prediction of air quality index using machine learning and try to evaluate their flaws and to estimate the new possible way of prediction using machine learning.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELgerogepatton
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
