In this work we applied base catalyzed transesterification to convert non-edible welted thistle oil (Carduus acanthoides) as new non-edible feedstock into biodiesel (Fatty acid methyl esters). The highest biodiesel yield of 88% was obtained using optimized reaction conditions of 70°C and 5:1 molar ratio (methanol:oil). The synthesized esters were characterize and confirmed by the application of NMR and FT-IR techniques. Gas chromatography and mass spectroscopy identified different fatty acids as palmatic acid (C16:0), oleic acid (C18:1), linoleic acid (18:2), arachidic acid (C20:0), eicosanic acid (C20:1), and erucic acid (C22:1) in the oil of welted thistle. Six corresponding methyl esters reported in welted thistle oil biodiesel includes 9-hexadecenoic acid, hexadecanoic acid, 9-octadecadienoic acid, 11-eicosanoic acid, eicosanoic acid and 13-docosenoicacid. Fuel properties, such as density @40°C Kg/L (0.8470), kinematic viscosity @ 40°C c St (4.37), flash point (95°C), cloud point (+4°C), pour point (?5°C), and sulfur contents (0.0112% wt) of the biodiesel produced were compatible with American Society for Testing and Materials D 6751 specifications. 相似文献

Achieving sustainability by introducing alternative livelihoods 总被引:2,自引:0,他引:2
The millennium ecosystem assessment report on global assessment of desertification has highlighted its worldwide impacts on
the environment—increasing dust storms, floods and global warming—as well as on societies and economies. It links sustainable
management of resources, and inter alia well-being of dryland populations, to reducing societal pressures on dryland ecosystems
through adoption of alternative livelihoods. This paper, in combination with a companion paper by Safriel and Adeel, presents
the conceptual underpinnings of this approach as well as examples of how innovative approaches for creating livelihoods can
help reduce the pressure on marginal drylands. Three case studies presented are based on activities undertaken within a joint
international project called sustainable management of marginal drylands. First, introduction of chicken farming to farmers
in Hunshundake Sandland in northern China has reduced the pressure on grasslands and led to a major recovery of these ecosystems.
Second, development of desert-based aquaculture, with accompanied longer-term storage of water, on the margins of the Cholistan
desert in Pakistan has provided a new source of income for the villagers. Third, development of a new income-generating activity
based on soap production from olive oil in Dana Biosphere Reserve in Jordan has demonstrated that traditional olive farming
can be linked to community-based innovation to create a new, high-demand market for goods. Working with communities to develop
new, sustainable livelihoods that reduce pressure on marginal drylands can thus be used as powerful tool for overcoming and
reversing desertification. 相似文献

Prior surveys conducted have found higher proportion of arsenic-contaminated wells in villages along river Indus in Pakistan. This study aims to determine the prevalence of arsenicosis skin lesions among population exposed to higher exposure in taluka Gambat district Khairpur in Sindh. The cross-sectional survey was conducted from August 2008 to January 2009 among 610 households. A total of 707 water sources (hand pumps/wells) were tested from the villages of union councils of Agra and Jado Wahan for arsenic levels with Quick rapid arsenic field test kits. A total of 110 households exposed to arsenic levels >50 ppb were identified. Case screening for arsenic skin lesions was performed for 610 individuals residing in these 110 high-risk households. Information regarding household and socio-demographic characteristics, height and weight measurements and arsenic exposure assessment were collected. Physical examinations by trained physicians were carried out to diagnose the arsenic skin lesions. After data cleaning, 534 individuals from all age groups were included in the final analysis which had complete exposure and outcome information. Overall prevalence of arsenicosis skin lesions was 13.5 % (72 cases). Of the 534 individuals, 490 (91.8 %) were exposed to arsenic levels of ≥100 ppb in drinking water (8.2 % to >50–99 ppb, 58.6 % to 100–299 ppb, 14.6 % to 300–399 ppb and 18 % to ≥400 ppb). Prevalence rate (per 100 population) of arsenicosis was highest at arsenic levels of 100–199 ppb (15.2 cases) followed by ≥400 ppb (13.5 cases) and 300–399 (12.8 cases). Prevalence rate was higher among females (15.2) compared to males (11.3). Our study reports arsenicosis burden due to exposure to higher arsenic levels in drinking water in Pakistan. Exposure to very high levels of arsenic in drinking water calls for urgent action along river Indus. Prevalence of skin lesions increases with increasing arsenic levels in drinking groundwater. Provision of arsenic-free drinking water is essential to avoid current and future burden of arsenicosis in Pakistan. 相似文献
