Spider webs in monitoring of air pollution

Spider webs in monitoring of air pollution

Rybak et al. also evaluated whether data obtained from webs reflect the level of air pollution measured with conventional methods [11]. The airborne particulate matter (PM) and associated heavy metals (Pb, Zn) collected in Wrocław were analysed with the use of classic method of air pollution assessment (impactors) and with webs of Malthonica silvestris. Study revealed correlation between average heavy metals concentrations on spider webs and average concentrations of Pb and Zn bound to submicron particles (PM1). Results conclude that content of heavy metals found on spider silk may not match the composition of corresponding elements present in bioaerosol. Overall, study confirmed usefulness of spider webs in monitoring of traffic emission as they are able to capture PM in a manner similar to flora-based bioindicators that have been used up to date, but spider silk have additional advantages like long time of exposition

Teleworking Effect on Traffic and Air Pollution

Teleworking Effect on Traffic and Air Pollution

There are four limitations and gaps in earlier studies that this paper attempted to cover. First, the majority of the studies used cross-sectional data and not longitudinal, and therefore the same individual is not followed across time. This limitation does not allow us for the investigation of the individual’s propensity to telework and the travelling behaviour and thus the impact of teleworking on air quality. This study uses a panel data analysis that allows to include the individual’s history into a fixed effects model and to account for omitted variables bias. The second limitation is that earlier studies explored either the relationship between traffic and teleworking or the impact of teleworking on air quality, without considering both associations into a panel data framework. The interrelationship among teleworking, traffic and air pollution into a longitudinal framework analysis allows the dynamic exploration of the teleworking impact on traffic and air quality. Third, while previous studies made use of IV approaches, the analysis is limited to the impact of teleworking on other outcomes, including well-being, job satisfaction, productivity and employee loyalty among others. So far there is no study using IV approaches to solve for the possible reverse causality between teleworking, air pollution and traffic. Fourth, the air pollution mapping methodology is not applied and the reduction on air pollution and greenhouse gas emissions is developed theoretically, according to the traffic and miles travelled reduction. On the contrary, in this study we use air pollution data in a rather high disaggregated area level and we employ real historical air pollution data. However, the disaggregation level is jot precise if we could implement the air quality mapping at post code level of the respondent’s residence. Therefore, we suggest the consideration of higher disaggregation level of the air quality for future research applications that will lead to even more robust and precise estimates. The main concluding remark is that teleworking has a positive impact on air quality, even this effect is low, in a European country, which is Switzerland. The results may significantly vary according to the country, the cultural factors, socio-economic characteristics, and other regional factors of the place explored. Thus, teleworking is suggested as one of the measures for urban planning and development and air quality improvement.

Biochemical changes of Conocarpus erectus (combretaceae) in response to gas refinery air pollution as an air pollution indicator

Biochemical changes of Conocarpus erectus (combretaceae) in response to gas refinery air pollution as an air pollution indicator

During pollution stress, ascorbic acid provides cell membrane stability. Increased ascorbic acid content can be the consequence of oxidative stress. The pH is one of the parameters, involved in APTI calculation, which is the element of ascorbic acid formation from hexose sugars. When the quantity of pH becomes more, the chance of this conversion increases as well; besides low amount of pH has a direct relation with the increase of plants sensitivity to air pollution. Also, total deal of chlorophyll &

PRESENT STATUS OF AIR POLLUTION IN THE TOWN OF NELLORE  ACTION PLAN FOR LOWERING OF AIR POLLUTION & AIR POLLUTION – HEALTH EFFECTS

PRESENT STATUS OF AIR POLLUTION IN THE TOWN OF NELLORE ACTION PLAN FOR LOWERING OF AIR POLLUTION & AIR POLLUTION – HEALTH EFFECTS

The air pollution is viewed as the most serious problem in many cities in India and accordingly Hon’ble Supreme Court of India has selected the cities depending upon the pollution load due to various activities. The transport sector is held largely responsible for the air pollution in the cities and the particulate matter is the most pollution causing agent in the cities. However, there are many other sources of the particulate emissions which include large industrial plants, medium and small scale industries, refuse burning, household burning biomass for cooking and heating, vehicular exhausts, re-suspended road dust, construction, particles migrating from other regions and naturally occurring dust. These sources emit the particles of different sizes of which the small particles are a cause of serious concern since they affect the public health more than the large particles.

Particulate Matter: An Approach To Air Pollution

Particulate Matter: An Approach To Air Pollution

Air pollution has been of major concern throughout the world due to the health effects on human, animal and materials. This issue is receiving much attention, due to the fact that both in developed and developing countries there has been an increase in urbanization due to higher activities in transportation and industrialization (Abiye et al., 2013). The growing concerns about the health implications of air, water, and soil pollution to ecosystem have led to the establishment of agencies which are saddled with the responsibility of combating the adverse effects (Ezeh et al., 2014). Examples of these organization, agencies and departments are World Health Organisation (WHO), United State Environmental Protection Agency (USEPA), United Nations (UN), and Central Pollution Control Board (CPCB) from India. The local, national and international agencies are working and concentrating on pollutions in the environment and publishing and issuing documents to improve the air quality.

Air Pollution Monitoring System

Air Pollution Monitoring System

There are two types of particulate matter – coarse and fine. Fine particulate matter is considered to be a major air pollutant. There are many web applications that use hardware sensors to collect data and measure the level of air pollution. Different applications collect different data from different places and use different formats for their storage and distribution, which complicates their standardized processing. The current work aims at presenting a conceptual model and prototype of a software application whose main functionalities are: aggregation of air pollution data from various sources; processing the data and its visualization in different formats to the end user, etc. The work presents the application architecture and its basic functionality.

Air Pollution and Children’s Health

Air Pollution and Children’s Health

Perhaps the most serious thing that can be done to a child’s life is to end it. Recently, a number of studies have reported that air pollution is associated with precisely that. In thinking about air pollution and death, one is inevitably led to the great air pol- lution episode of December 1–5, 1952, in London. A low-level thermal inversion that trapped coal smoke in the Thames valley, coupled with a stationary front that dropped wind speed to 0, resulted in a rapid buildup of pollution to extremely high levels. Ap- proximately 4000 excess deaths occurred in London in that week, 29 and elevated death rates continued

Real Time Monitoring of Air Pollution

Real Time Monitoring of Air Pollution

industries which releases a mixture of various toxic gases and particulates of various sizes. These gases when inhaled causes damage to lung parenchyma and the micro-particles settles in the lung inducing inflammation and damage to lung tissues. This makes an individual prone for occupational lung diseases. Industry pollution is a mixture of various gases including carbon monoxide, hydrocarbons, oxides of sulphur and nitrogen. These gases inhaled over period of time compromises the pulmonary functions and causes pulmonary diseases. Periodic assessment of these gas levels in the industry is mandatory to maintain health of the individuals. The instrument devised works based on air sensing technology. The instrument could be installed in the industry working area and the data collected through the instrument will be transferred to virtual data storage (CLOUD). These data could be accessed anywhere through internet connected mobile which could be used by Government agencies, Safety officers and industries to assess air pollution level which acts an alarm and helps in taking adequate protective measures to reduce air pollution level in the environment. As industrial safety is very important for workers, inventing a fast, easily accessible instrument helps in monitoring the air pollution level, which in turn helps to take adequate steps to promote worker’s health and productivity of the industry.

Air Pollution, Smoking, and Plasma Homocysteine

Air Pollution, Smoking, and Plasma Homocysteine

Air pollution and weather data. We obtained from the Regional Environmental Protection Agency (ARPA Lombardia) record- ings of hourly air pollution data measured from January 1994 to September 2005 by monitors located at 53 different sites through- out Lombardia (Figure 1A). The 53 stations included in this study were selected by ARPA Lombardia from the approximately 200 mon- itors of the Regional Air Monitoring Network on the basis of their location, reliability, determined by standardized quality control procedures and by correlation with in situ measurements, and continuity of recording. We identified nine different study areas in the region (Figure 1A) characterized by homoge- neous within-area air pollution concentra- tions. Within each study area, levels of air pollutants measured by different monitors were highly correlated. The urban and subur- ban Milan areas (areas 1 and 2) included approximately 65% of the study subjects

Health effects of outdoor air pollution

Health effects of outdoor air pollution

Air pollutants are usually present in the air as a mixture, or “soup,” of constituent gases and particles. The main pollutants and their sources are shown in Table 2. In gen- eral, combustion of fossil fuels for transportation, home heating and cooling, and industry are the main sources of air pollution. Pollution can be regional when large geo- graphic areas are covered by pollution (for example, the smog [mostly ozone and particulate matter] in the Quebec City–Windsor corridor, the Fraser River Basin, and south- ern Atlantic Canada) or local, such as pollution from traffic, local industries, or wood smoke. Motor vehicle emissions consist mostly of carbon monoxide, nitrogen oxides, vola- tile organic compounds, and particulate matter (PM); lev- els are elevated close to busy roads, but fall off rapidly within 150 m of the road. The most common pollutants, listed in Table 2, are widely monitored.

Study on Effect of Air Pollution on Health

Study on Effect of Air Pollution on Health

Many studies have observed associations between particulate air pollution and human health [17]. Increases in sickness and death associated with severe air pollution episodes have been well documented. Particulate air pollution is a mixture of particles that vary in size, composition, and origin. Fine particles are the largest health concern because they can be breathed most deeply into the lung. This size range includes most sulfate particles. Unlike larger particles which are derived primarily from soil and other crustal materials, fine particles are derived chiefly from combustion of fossil fuels in processes such as transportation, manufacturing, and power generation. Sulfate particles are commonly generated by conversion from primary sulfur emissions and a varying portion of sulfate particles may be acidic.

Overview of air pollution and endocrine disorders

Overview of air pollution and endocrine disorders

From the research discussed above in the section entitled “Sources of exposure to EDCs in air”, it is clear that air pollution includes many EDCs and that EDCs are entering human tissues. However, the question then remains as to the extent to which EDCs in air can contribute to the overall EDC body burdens. Over the past several decades, many cases of endocrine disruption in aquatic organisms have been linked directly to concentrations of EDCs in the water environment leading to reproductive problems and consequent population declines. 126,127 Early work showed that tributyltin in antifouling

Changes in atmospheric chemistry that result in impacts on human health or the environment can often occur outside as well. These changes are typically known as air pollution, of which there are two principal kinds, pollution that is released from a single, identifiable source, known as a point source and pollution that comes from a large number of dispersed sources, known as non-point or area sources of pollution. Point sources of air pollution include toxic trace compounds emitted from specific industries. This type of pollution, known as local air toxics, presents an air quality problem in the vicinity of these industries. These pollutants include heavy metals such as beryllium, cadmium, and mercury, organic compounds such as aldehydes and furans and radioactive particles and gases. Occasionally, large-scale toxic emissions from industrial facilities, such as the industrial accident in 1984 in Bhopal, India, pose severely deleterious effects on human health. Other localized air quality concerns include noxious odors from industrial facilities, landfills, and sewage treatment facilities.
