Evaluation and analysis of noise levels in Ilorin metropolis, Nigeria
Evaluation and analysis of noise pollution
levels have been carried out to determine the
level of noise and its sources in Ilorin metropolis.
Noise measurements have been done in the
morning, at noon, in the evening, and at night
to determine noise pollution all over the city.
The selected areas of study are commercial centers,
road junctions/busy roads, passenger loading
parks, and high-density and low-density residential
areas. The road junctions had the highest noise
pollution levels, followed by commercial centers.
The results of this study show that the noise levels
in Ilorin metropolis exceeded allowed values at
30 of 42 measurements points. There is a significant
difference (P < 0.05) in the noise pollution
levels and traffic noise index in all the locations.
From the measured noise values, a map of noise
pollution was developed for Ilorin. Many solutions
proposed for noise abatement in the city are
set out
Pollution, Shadow Economy and Corruption: Theory and Evidence
We study how the shadow economy affects pollution and how this effect depends on corruption levels in public administration. Production in the shadow economy allows firms to avoid environmental regulation policies; a large informal sector may be accompanied by higher pollution levels. Our theoretical model predicts that controlling the levels of corruption can limit the effect of the shadow economy on pollution. We use panel data covering the period from 1999–2005 from more than 100 countries to test this theoretical prediction. Our estimates confirm that the relationship between the shadow economy and the levels of pollution are dependent on the levels of corruption. Our results hold when we control for the effects of other determinants of pollution, time varying common shocks, country-fixed effects and various additional covariates.environmental pollution, shadow economy, corruption, panel data
Fine Particulate Matter and Ozone Air Quality in Western Pennsylvania in the 2000s
Presents data on the area's particulate matter, ozone, and emissions levels and air pollution sources. Examines air quality compared with the rest of the nation, links between premature death and harmful levels of air pollution, and monitoring networks
Statistical Methodological Issues in Studies of Air Pollution and Respiratory Disease.
Epidemiological studies have consistently shown short term associations between levels of air pollution and respiratory disease in countries of diverse populations, geographical locations and varying levels of air pollution and climate. The aims of this paper are: (1) to assess the sensitivity of the observed pollution effects to model specification, with particular emphasis on the inclusion of seasonally adjusted covariates; and (2) to study the effect of air pollution on respiratory disease in Melbourne, Australia.Air pollution; Autocorrelation; Generalized additive models; Seasonal adjustment; Respiratory disease
Pollution Exposure and Infant Health: Evidence from Germany
This paper examines the impact of outdoor and indoor pollution on children's health from birth until the age of three years in Germany. We use representative data from the German Socio-Economic Panel (SOEP), combined with five air pollution levels. These data come from the Federal Environment Agency and cover the years 2002-2007. Our work offers three important contributions. Firstly, we use accurate measures for five different pollutants (CO, NO2, SO2, O3, and PM10) on a (half-)hourly basis. Secondly, we are able to follow the effect of pollution exposure on a child's health during the first three years of life, accounting for time-invariant and unobserved neighborhood and mother-specific characteristics. Thirdly, we calculate different pollution intensity measures. Instead of relying solely on mean pollution levels, we are able to use (half-)hourly pollution levels as well as indoor pollution as measurements for the total latent pollution exposure. Our results suggest a significantly negative impact for some pollutants on infant health during early childhood. In comparison to outdoor pollution, indoor pollution seems to be more harmful directly after birth, while the relationship between indoor and outdoor pollution changes later in childhood. Since smoking is one source of producing carbon monoxide and thus affects child health negatively, our results further support the advice to parents of young children not to smoke.Indoor and outdoor pollution, health, early childhood

Simple traffic measures significantly reduce the exposure of primary school children to NO<sub>2</sub>
According to Public Health England (PHE, 2019) air quality is the largest environmental health risk in the UK; long-term exposure to air pollution claims some 28-36,000 premature deaths each year. It shortens lives and contributes to chronic illness. Health can be affected both by short-term, high-pollution episodes and by long-term exposure to lower levels of pollution. Environmental Health Officers (EHOs) are directly involved in managing and monitoring local air quality, but often direct action is only taken when there are exceedances of statutory limits and standards. A previous publication, REHIS Journal Autumn 2018, makes the case that long term exposure to lower than limit levels of air pollution can have significant health impacts in later life and that the developing lungs of children are at risk. PHE goes on to state that ‘effective communication of health messages about air pollution and appropriate action can save lives and improve quality of life for many’ (PHE, 2019)
Exposure to Household Air Pollution from Biomass-Burning Cookstoves and HbA1c and Diabetic Status Among Honduran Women
Household air pollution from biomass cookstoves is estimated to be responsible for more than two and a half million premature deaths annually, primarily in low and middle‐income countries where cardiometabolic disorders, such as Type II Diabetes, are increasing. Growing evidence supports a link between ambient air pollution and diabetes, but evidence for household air pollution is limited. This cross‐sectional study of 142 women (72 with traditional stoves and 70 with cleaner‐burning Justa stoves) in rural Honduras evaluated the association of exposure to household air pollution (stove type, 24‐hour average kitchen and personal fine particulate matter [PM2.5] mass and black carbon) with glycated hemoglobin (HbA1c) levels and diabetic status based on HbA1c levels. The prevalence ratio (PR) per interquartile range increase in pollution concentration indicated higher prevalence of prediabetes/diabetes (vs normal HbA1c) for all pollutant measures (eg, PR per 84 μg/m3 increase in personal PM2.5, 1.49; 95% confidence interval [CI], 1.11‐2.01). Results for HbA1c as a continuous variable were generally in the hypothesized direction. These results provide some evidence linking household air pollution with the prevalence of prediabetes/diabetes, and, if confirmed, suggest that the global public health impact of household air pollution may be broader than currently estimated
Optimal Pollution Abatement - Whose Benefits Matter, and How Much?
We examine measures of environmental regulatory activity (inspections and enforcement actions) and levels of air and water pollution at approximately 300 U.S. pulp and paper mills, using data for 1985-1997. We find that levels of air and water pollution emissions are affected both by the benefits from pollution abatement and by the characteristics of the people exposed to the pollution. The results suggest substantial differences in the weights assigned to different types of people: the benefits received by out-of-state people seem to count only half as much as benefits received in-state, although their weight increases if the bordering state's Congressional delegation is strongly pro-environment. Some variables are also associated with greater regulatory activity being directed towards the plant, but those results are less consistent with our hypotheses than the pollution emissions results. One set of results was consistently contrary to expectations: plants with more nonwhites nearby emit less pollution. Some of our results might be due to endogenous sorting of people based on pollution levels, but an attempt to examine this using the local population turnover rate found evidence of sorting for only one of four pollutants.
