Pesticides are known to improve agriculture yield considerably leading to an increase in its application over the years. The use of pesticides has shown varying detrimental effects in humans as well as the environment. Presently, enough evidence is available to suggest their misuse and overuse in the last few decades in most developing nations primarily due to lack of education, endangering the lives of farmers as well as the entire population and environment. However, there is paucity of data especially over long durations in Ghana resulting in the absence of effective monitoring programs regarding pesticide application and subsequent contamination in fruits and vegetables. Therefore, this review discusses comprehensively pesticide type and use, importation, presence in fruits and vegetables, human exposure, and poisoning in Ghana. This is to alert the scientific community in Ghana of the need to further research into the potential implications of pesticide residues in food commodities in order to generate a comprehensive and reliable database which is key in drafting policies simultaneous with food regulation, suitable monitoring initiatives, assessment, and education to minimize their effects thereon. 相似文献

This study attempted to identify the unique components of burnout among school principals using Facet Theory as a theory construction tool. A total of 571 elementary and secondary school principals in Israel completed a questionnaire containing items relating to their feelings about themselves, their environment and work. Data were analyzed employing Small Space Analysis (SSA). Results indicated that burnout among school principals may be presented in a two-dimensional space, incorporating: experiences (weariness or discontent), and the focus (internal or external) of those experiences. Four components of the burnout phenomenon in principals emerged in this two-dimensional space: exhaustion, self-discontent, aloofness, and deprecation. 相似文献

This paper explores the complex heterogeneous experiences of flood impacts based on a bio-psychosocial model of socio-economic, demographic, behavioural and environmental factors. Using ordinary least squares regression on a cross-sectional survey of 1003 individuals, flood impacts in three contiguous coastal neighbourhoods in Lagos, Nigeria, were modelled. The results show that approximately 52% of the variability in flood impact was accounted for by education, age, family structure, ethnicity, personal health concern and income. While involvement in coping was not a significant predictor of flood impacts, relocation emerged as a strong predictor. The inclusion of behavioural factors did not change the magnitude and significance of the relationship between demographic factors and flood impacts. However, the effects of age, education and personal health concern disappeared when environmental factors were controlled. The overall importance of the predictors for determining flood impact in decreasing order is as follows: income > coping strategies > ethnicity = participation in community development > family structure > personal health concerns > housing quality > reasons for living in residential locality > neighbourhood vulnerability to flood > housing vulnerability to flood. 相似文献

This study was aimed to establish background and reference values of total heavy metals in soils from a representative area of Albania (Tirana). Thirty-eight soil samples collected from genetic horizons of major soil types of Tirana were analyzed for important physicochemical properties by standard methods and for total contents of Cd, Cr, Ni, Pb, Zn, and Cu by atomic absorption spectrometer, after extraction with aqua regia. The results showed that the total contents of Cd, Cr, Ni, Pb, Zn, and Cu in surface horizons varied widely with respective mean values of 0.3 (??0.6), 174.2 (??63.7), 305.9 (??133.0), 19.7 (??12.4), 95.5 (??26.3), and 42.7 (??6.8) mg/kg. The highest metal contents were found in two soils developed in limestone. The depth distribution of metals showed a tendency for accumulation of Cd and Pb in the surface horizons of three soils, suggesting that these metals partially come from anthropogenic inputs. Correlation analysis indicated that the metal contents of soils were controlled by soil properties, including pH, CaCO3, clay, organic matter, cation exchange capacity, and Fe oxides. The background values (given as the 90th percentile) were much higher than those reported in the literature, showing that the levels of respective metals were naturally higher. The total metal contents of some soils were above background levels, suggesting metal pollution. The reference values for all the analyzed metals were quite consistent with those of the Dutch system. The proposed background and reference values can be used to evaluate the soil pollution with these elements. 相似文献

The increasing number of incidences of alleged wildlife poisoning with Furadan in Kenya has sparked off a strong lobby fronted
by wildlife conservationists against Furadan use in the country and prompted this study. The worst-case scenario was in 2004
in Athi River, where a massive number of 187 African white-backed vultures (Gyps africanus) and hyenas were found dead at a spot where poisoning was suspected to have occurred through a Furadan-laced camel carcass
bait. This study was initiated by the Peregrine Fund—Africa Project, and the objective was to provide evidence for Furadan
exposure, its misuse and involvement in vulture poisoning and potential impact on areas near two wildlife conservancies in
two most affected districts. The study found evidence for ready availability of Furadan 5G in local veterinary retail shops
and its illegal misuse by pastoralists and farmers against wildlife to protect their animals and crops. Analysis of soil,
water and plants taken from the farms and water sources by high-perfomance liquid chromatography (HPLC) and gas liquid chromatography–mass
spectrometry (GC–MS) found residues of carbofuran, 3-hydroxycarbofuran and 3-ketocarbofuran, indicating that Furadan was used
extensively in farming causing residual environmental distribution and contamination and posing risks to small birds and mammals.
Forensic analysis of residues in beaks, feet and crop content of the dead vultures as well as in a laced camel carcass bait
and soil samples from one site of poisoning also showed carbofuran and its two metabolites supporting allegations of Furadan
involvement in wildlife poisoning and high-mortality cases of African white-backed vultures (Gyps africanus) in Kenya. 相似文献

Small-holder farmers often develop adaptable agroforestry management techniques to improve and diversify crop production.
In the cocoa growing region of Ghana, local knowledge on such farm management holds a noteworthy role in the overall farm
development. The documentation and analysis of such knowledge use in cocoa agroforests may afford an applicable framework
to determine mechanisms driving farmer preference and indicators in farm management. This study employed 12 in-depth farmer
interviews regarding variables in farm management as a unit of analysis and utilized cognitive mapping as a qualitative method
of analysis. Our objectives were (1) to illustrate and describe agroforestry management variables and associated farm practices,
(2) to determine the scope of decision making of individual farmers, and (3) to investigate the suitability of cognitive mapping
as a tool for assessing local knowledge use. Results from the cognitive maps revealed an average of 16 ± 3 variables and 19 ± 3
links between management variables in the farmer cognitive maps. Farmer use of advantageous ecological processes was highly
central to farm management (48% of all variables), particularly manipulation of organic matter, shade and food crop establishment,
and maintenance of a tree stratum as the most common, highly linked variables. Over 85% of variables included bidirectional
arrows, interpreted as farm management practices dominated by controllable factors, insofar as farmers indicated an ability
to alter most farm characteristics. Local knowledge use on cocoa production revealed detailed indicators for site evaluation,
thus affecting farm preparation and management. Our findings suggest that amid multisourced information under conditions of
uncertainty, strategies for adaptable agroforestry management should integrate existing and localized management frameworks
and that cognitive mapping provides a tool-based approach to advance such a management support system. 相似文献

This study examines the perceptions and coping strategies of the Aamjiwnaang First Nation, which is surrounded by ‘Chemical Valley’, the largest complex of petrochemical plants in Canada. Analysis of in-depth interviews showed that residents perceive ‘Mother Earth to be sick’; however, a strong level of community cohesion prevails, with ‘place’ as a significant anchor to the culture and history of the community. Residents articulated a collective sense of responsibility for the well-being of members both within and surrounding the community, whereby some residents would never leave, regardless of the toxic environment and concern for high rates of cancer and respiratory diseases among both adults and children. Residents employed action-focused coping strategies such as ‘indoor evacuation’ and the ‘Cop-sniff test’, and emotional coping strategies including blocking out the effects of ‘Chemical Valley’ by frequently ignoring warning sirens from industry. The results call on the need for a collaborative environmental planning intervention involving clear community participation. Findings suggest the need for an indoor recreational facility for both children and adults, and a graded warning system. 相似文献

Evaluation of the critical factors controlling stability of chromium, copper, arsenic and zinc in iron-treated soil 总被引:3,自引:0,他引:3
Various environmental factors are expected to affect the mobility of elements in chemically stabilized soils. The aim of this study was to evaluate the effects of pH, oxidizing-reducing potential (Eh), liquid-to-solid ratio (L/S), presence of organic matter (OM) and microbial activity (MA) on the mobility of chromium, copper, arsenic and zinc in zerovalent iron (Fe(0))-stabilized soil. A 2(5) full factorial design was applied to assess the leaching of the elements from the treated soil. The factor having the most impact on the mobility of Cr, Cu and Zn was pH; low pH (3) led to the release of these elements. Arsenic remobilization was controlled by L/S and MA, whilst Eh, though also significant, had less influence. In the identified worst-case scenarios, more than half of the total Zn and Cu and 14% of As can be expected to remobilize from the treated soil. The leaching procedure concerning sample agitation and type of filtration showed to substantially affect the results of As leaching, especially in OM rich soil. 相似文献
