“…Additionally, there is limited information on micro-climates inside archival boxes (Dupont and Tétreault, 2000;Wise et al, 2005), particularly in relation to the migration of pollutants into and out of the boxes. So far, most analyses of VOCs in museum environments focussed on measurements of organic acids (Gibson et al, 1997;Srivastava et al, 2000;Ryhl-Svendsen and Glastrup, 2002) and a method development for formaldehyde determination using passive samplers was described (Gibson et al, 2008).…”

Volatile aldehydes are produced during degradation of paper-based materials. This may result in their accumulation in archival and library repositories. However, no systematic study has been performed so far. In the frame of this study, passive sampling was carried out at ten locations in four libraries and archives. Despite the very variable sampling locations, no major differences were found, although air-filtered repositories were found to have lower concentrations while a non-ventilated newspaper repository exhibited the highest concentrations of volatile aldehydes (formaldehyde, acetaldehyde, furfural and hexanal). Five employees in one institution were also provided with personal passive samplers to investigate employees' exposure to volatile aldehydes. All values were lower than the presently valid exposure limits.The concentration of volatile aldehydes, acetic acid, and volatile organic compounds (VOCs) in general was also compared with that of outdoor-generated pollutants. It was evident that inside the repository and particularly inside archival boxes, the concentration of VOCs and acetic acid was much higher than the concentration of outdoor-generated pollutants, which are otherwise more routinely studied in connection with heritage materials. This indicates that further work on the pro-degradative effect of VOCs on heritage materials is necessary and that monitoring of VOCs in heritage institutions should become more widespread.

“…The indoor/outdoor VOCs ratio (I/O) and intercept and slope values of regression analysis have been presented in Table 3. MP-and HT-indoors have shown I/O ratios in unit range, whereas MG-and BT-indoors have shown tens of those occurred in earlier; contrast observations compared to residential-indoors and earlier reported values of < 1 (Srivastava et al, 2000;Son et al, 2003;Srivastava and Devotta, 2007 have shown slightly higher contribution (53.2-56.8%) from indoor sources compared to outdoor ones. As far as indoor/outdoor contribution to specific VOCs is concern, n-hexane and n-heptane have shown lower contribution (31.5-48.9%) from indoor sources compared to outdoors, which can also be justified by higher R 2 values.…”

“…automobile exhaust and municipal waste burning (Pagans et al, 2006;Srivastava et al, 2006;Chiriac et al, 2011;Hsieh et al, 2011) Cyclohexane, n-octane, ethylbenzene, oxylene and n-undecane have shown major contribution (60.8-85.1%) from indoor sources compared to outdoor sources. In case of residential-indoors, n-hexane has shown major contribution from indoor sources; this might be due to: 1) LPG use for cooking purposes and 2) solvent use for cleaning purposes in homes (Srivastava et al, 2000;Huang et al, 2011).…”

“…Volatile organic compounds (VOCs) have now been identified as one of the major indoor air contaminants due to construction of well-sealed houses using various types of insulators (Berk et al, 1980), usage of painting materials in indoor-houses (Srivastava et al, 2000), household cooking fuels (Liquid petroleum gas, kerosene, solid fuels etc.) (Sinha et al, 2006;Huang et al, 2011), adhesive-bonded material use in plywood/ PVC flooring (Low et al, 1998;Wilke et al, 2004;Jarnstom et al, 2008;Choi et al, 2010;Kang et al, 2013) and house furniture's (Fisher et al, 1962;NRC, 1980;USDHUP, 1980;Franklin, 1981).…”

Measurements of selected volatile organic compounds (VOCs), known as markers of emissions resulting from burning practices using natural-and synthetic biomaterials, have been carried out in major religious/ritual-indoors in India. Four different religious/ritual-indoors were selected for monitoring purposes: 1) Hindu Marriage Places (MP), 2) Muslim Holy Shrines (MG), 3) Buddhist Temples (BT), and 4) Hindu Temples (HT). One pure residential-indoor (RESID) site was also examined for comparison studies. Indoor VOCs sampling was carried out throughout the three seasons of summer, fall and winter of the calendar year of 2012-2013 in Raipur, India. VOCs samples, collected by passive sampling over a 48-h period, were analyzed using thermal desorption (TD), followed by high-resolution gas chromatographic separation and mass spectrometric detection (GC/MS). A total of 14 volatile organic compounds (n-hexane, cyclohexane, n-heptane, noctane, n-nonane, n-decane, n-undecane, styrene, o-xylene, m,p-xylene, 1,2,4-trimethyl benzene, ethylbenzene, benzene, and toluene.) were quantified. The annual mean concentrations for total VOCs (TVOCs) were 216. 61 ± 75.15, 656.34 ± 220.82, 681.75 ± 219.83, 129.51 ± 45.24 and 82.67 ± 40.96 µg/m 3 for MP, MG, BT, HT and RESID respectively. The results were found to be higher than the prescribed standards and earlier reported indoor VOCs levels. Indoor/outdoor ratios (I/O), correlation analyses, seasonal variations and indoor/outdoor contributions to the measured levels are also investigated.

“…The use of kerosene for lighting in rural households causes high concentrations of particulate matter, volatile organic compounds, sulphur dioxide and carbon monoxide. 18,19 The increased electricity consumption followed by a grid extension is likely to be supplied by thermal power production, using either crude oil or natural gas. This may cause environmental impacts on a regional level or locally at the site of the power plant (Takoradi), as a number of problems can be linked to the use of fossil fuels.…”

The competitiveness of distributed solar photovoltaic (PV) power generation for rural electrification in northern Ghana is assessed and compared with the conventional option of extending the national grid and increasing the capacity for centralised power generation. A model is constructed to calculate the life-cycle cost (LCC) of the two options and to test the sensitivity of different parameters. All calculations are based on information from the GEF/UNDP pilot region in the East Mamprusi District. In addition to the economic aspect, issues of quality and environmental effects are discussed. The LCC of distributed PV is lower than that of a grid extension for an electricity demand corresponding to solar home systems of 140 W p or smaller. Thus, distributed PV is cost competitive for purposes of lighting, entertainment, information and basic public facilities, such as schools and hospitals. The LCC for the option of grid extension with central power generation is dominated by the cost of low-voltage micro-grids within the communities. Important factors are the density of households and the penetration (fraction of households electrified), as they affect the line length per connected household. The relatively low cost of regional mediumvoltage grids makes the geographical location of each community less important than expected. Battery replacement every fifth year makes up the major part of the LCC of solar home systems and is also responsible for the large energy input in the production of the systems. This could limit both future cost reductions of distributed PV and its potential to mitigate greenhouse gas emissions.
