“…In line with previous research (Erdogan, Ok, and Marcinkowski 2012;Ugulu 2015), the KMO and Bartlett tests, an exploratory factor analysis, descriptive statistics, Cronbach's alpha, and a CFA were computed. The stability of the scale was assessed by using multi-group invariance testing.…”

“…The first research question asked about the validity of the four-dimension model of ASD. The KMO and Bartlett tests were the first statistical analyses performed to verify suitability of the data for an exploratory factor analysis (Ugulu 2015). A KMO value over .90 is optimal (Russell 2002), and the values of the Bartlett test suggest that the null hypothesis must be rejected when there is a significance level of .05 (Snedecor and Cochran 1989).…”

“…The Cronbach's alpha of .660 for the society factor was also accepted if it was low, because some reliability values lower than .70 were reported in other preliminary studies (Biasutti and Frezza 2009;Liu 2003), and also for factors with less than six items (Kyle, Graefe, and Manning 2005). For these reasons, the Cronbach's alpha of value of .660 is considered acceptable for this research (Ugulu 2015). The results are shown in Table 3, which indicate that the scale has good internal consistency.…”

This article describes the development and validation of the Attitudes toward Sustainable Development scale, a quantitative 20-item scale that measures Italian university students' attitudes toward sustainable development. A total of 484 undergraduate students completed the questionnaire. The validity and reliability of the scale was statistically tested by computing the KMO and Bartlett tests and via an exploratory factor analysis, descriptive statistics, Cronbach's alpha, a confirmatory factor analysis and a multi-group invariance testing. The results of the principal components factor analysis show that the scale consists of the following four dimensions, with five items in each: environment, economy, society and education. The overall structure and measurement of the scale are confirmed by the confirmatory factor analysis and by the multi-group invariance testing. Internal reliability, which was found using Cronbach's alpha, varies between .660 and .854. The results show that the instrument meets the validity and reliability criteria. To demonstrate its utility, the scale was applied to detect differences in sustainable development attitudes among students pursuing degrees in psychology and in agriculture. Relevant differences were detected for the dimensions of environment and society. The Attitudes toward Sustainable Development scale could be useful for understanding the ways in which students think about sustainability issues and could be used to investigate the relationship between sustainability attitudes and other variables.

“…Toxic percentages of heavy metals are released into environment by anthropogenic and geologic activities. These activities include utilization of pesticides and fertilizers in agriculture, mining, fossil fuel burning, smelting process of metals, batteries production and production of different metals in sewage sludge, industries, and public waste disposal [10][11][12]. Incessant irrigation with wastewater, results in accumulation of heavy metals in the soil, which ultimately affects the development of plant [13].…”

This study was carried out for the determination of cobalt (Co) accumulation in four varieties of maize (grains, shoot and root) and in seven tissues of chickens (blood, bone, breast meat, kidney, liver, heart and gizzard) using wet digestion method by atomic absorption spectrophotometer. Representative samples of water, soil, grains and different chicken parts were assayed for Co contents. Compared to canal and ground water, sewage water had the highest concentration of Co, which is the reason why the maize plants irrigated with sewage water had the highest Co concentration. The group of chickens that were reared with grains treated by sewage water treated grains also showed the highest Co concentration in their body parts compared to the other groups. Enrichment factor and pollution load index for the soil, as well as bioconcentration, bioaccumulation and transfer factors were assessed to evaluate the transfer of Co from water to soil and to the plant. Target Hazard Quotient (THQ) was also calculated to estimate the potential human health risk of Co contamination from consumption of selected chicken parts (liver, breast meat and gizzard) by the local inhabitants and found the THQ values <1. THQ values for Co were less than 1.0 for meat, liver and gizzard which indicated that the exposed population was unlikely to experience obvious adverse effects on utilization of these poultry edibles.

“…Anthropogenic activities affect all components of the biosphere and alter the normal biogeochemical cycles (Ugulu 2015b). Heavy metal contamination, for instance, has increased sharply since 1900 and causes major environmental problems worldwide Freitas 2003, Baslar et al 2009).…”

Malva sylvestris is a widely consumed edible-medicinal plant with a natural distribution all around the world. The aim of this study is to determine the concentration levels of heavy metals, such as cadmium, chromium, copper, iron, manganese, nickel, lead, and zinc, in the M. sylvestris samples from different local markets in the province of Izmir, Turkey. The analyses of the heavy metals Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn was realized by inductively coupled plasma optical emission spectroscopy. At the end of the study, the mean concentrations determined for the unwashed plant samples were as follows: The contents of Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn (μgg -1 , dry weight) varied between 0.035 and 0.262, 0.247 and 1.133, 1.611 and 43.27, 7.425 and 568.6, 0.340 and 57.61, 0.090 and 2.563, 0.032 and 1.712, and 5.309 and 75.47, respectively. For the washed plant samples, however, the contents of Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn (μgg -1 , dry weight) varied between 0.026 and 0.172, 0.153 and 0.462, 0.247-68.34, 7.407 and 187.5, 0.340 and 49.99, 0.042 and 1.332, 0.005 and 0.502, and 5.314 and 60.37, respectively. The findings show that the heavy metal concentrations of all the heavy metals determined in the washed plant samples were lower.

İzmir Pazarlarında Satılan Malva sylvestris Örneklerinin Ağır Metal Birikim Değerleri Özet Malva sylvestris, dünyada yaygın bir şekilde tıbbi ve yemeklik olarak tüketilen bir bitkidir. Bu çalışmada İzmir'in çeşitli pazarlarında satılan M. sylvestris örneklerindeki kadmiyum, krom, bakır, demir, manganez, nikel, kurşun ve çinko birikim değerleri araştırılmıştır. Bitki örneklerindeki birikim değerlerinin tespiti ICP-OES ile gerçekleştirilmiştir. Çalışma sonunda yıkanmamış bitki örneklerindeki değerler Cd, Cr, Cu, Fe, Mn, Ni, Pb ve Zn için sırasıyla 0.035 ve 0.262, 0.247 ve 1.133, 1.611 ve 43.27, 7.425 ve 568.6, 0.340 ve 57.61, 0.090 ve 2.563, 0.032 ve 1.712, 5.309 ve 75.47 (μgg -1 , kuru ağırlık) arasındadır. Yıkanmış bitki örnekleri için ise Cd, Cr, Cu, Fe, Mn, Ni, Pb ve Zn içeriği sırasıyla 0.026 ve 0.172, 0.153 ve 0.462, 0.247 ve 68.34, 7.407 ve 187.5, 0.340 ve 49.99, 0.042 ve 1.332, 0.005 ve 0.502, 5.314 ve 60.37 (μgg -1 , kuru ağırlık) arasındadır. Bulgular yıkanmış bitki örneklerindeki birikim değerlerinin tüm ağır metaller için daha düşük olduğunu göstermiştir Anahtar Kelimeler: Malva sylvestris, ağır metal, yabani yenilebilir bitki, ICP-OES, İzmir.
