“…Regardless many authors (Schuphan,1975, Roussos andGasparatos, 2009;de Souza Araújo et al, 2014) reported higher contents of minerals (Ca, K and P) in the crops from organic farming in our study higher mineral contents were determined mostly in conventional crops. Among organically grown samples more calcium was determined in basil, parsley, pear, pepper, rocket and celery.…”

The present study aims to compare mineral composition of fruits, herbs and vegetables grown conventionally and according to organic practice. Fruits, herbs and vegetables have been identified as leading dietary source of antioxidants, vitamins and minerals. These compounds are very variable in the composition and in the concentration among cultivars and species. Determination of calcium (Ca), potassium (K), phosphorus (P) sulphur (S) and chlorine (Cl) was performed with Energy dispersive X-ray fluorescence spectrometry (EDXRF). We found that among organic crops basil, parsley, pears, peppers, rockets and celery had higher calcium contents in comparison to conventional ones. Organically produced broccoli, eggplant, parsley, rocket and celery had higher potassium contents as well as pepper, rockets, celery, beetroots and tomatoes had higher phosphorus contents. Likewise, higher sulphur content was found in organically produced parsley, rocket, celery and raspberries. Results of this study demonstrated that in general there are no rules in the content of minerals between different farming systems.Key words: mineral content, EDXRF, organic farming, conventional farming, fruits, herbs, vegetables IZVLEČEK RAZLIKE V VSEBNOSTI MINERALOV MED SLOVENSKIM EKOLOŠKO IN KONVENCIONALNO PRIDELANIM SADJEM, ZELIŠČI IN ZELENJAVONamen opravljene študije je narediti primerjavo vsebnosti mineralov ekoloških in konvencionalnih pridelkov glede na način kmetovanja. Sadje, zelišča in zelenjava so poznani kot glavni vir prehranskih antioksidantov, vitaminov in mineralov. Te spojine se razlikujejo glede na sestavo in koncentracijo znotraj posameznih vrst. Energijsko disperzijska rentgenska fluorescentna spektrometrija (EDXRF) je bila uporabljena za določevanje vsebnosti kalcija (Ca), kalija (K), fosforja (P), žvepla (S) in klora (Cl). Ugotovili smo, da so imeli med ekološkimi pridelki večje vsebnosti kalcija bazilika, peteršilj, hruška, paprika, rukola in zelena. Večje vsebnosti kalija so bile v ekološkem brokoliju, melancanu, peteršilju, rukoli in zeleni, v primerjavi s konvencionalnimi pridelki. Večje vsebnosti fosforja so bile v ekološki papriki, rukoli, zeleni, rdeči pesi in paradižniku. Glede na konvencionalne pridelke je bila večja vsebnost žvepla izmerjena v peteršilju, rukoli, zeleni in malinah. Rezultati so pokazali, da se vsebnost mineralov v pridelkih ne razlikuje glede na različen načinov kmetovanja.

“…Many believe that "organically" grown crops are "better" health-wise. In some instances, this is the case, but even without some of the usual additives, there is an increased contamination when contaminated groundwater is used for irrigation [32]. Even with the differing farming systems, and the public's perception that organically grown foods are healthier, increased surveillance and screening must be done to monitor the amount of potentially harmful chemicals that are being ingested on a daily basis [33].…”

The intent of this chapter is to provide an overview to the current thoughts and ideals regarding the involvement of pesticides and heavy metals in the progress of breast cancer. The history of pesticides encompasses a few millennia, but our understanding of the pesticide action and the health consequences has only begun to develop in the last -years. Interestingly, many of these pesticides have estrogen-like activity and may be involved in the development of breast cancer. " new category of estrogen-like compounds has been identified and studied in the last years, the metalloestrogens . Heavy metals, such as cadmium, which have estrogen like activity will be discussed. Finally, we will attempt to pull together the actions of pesticides and metalloestrogens as a possible synergistic mechanism by which these toxins may work to promote breast cancer development.

“…The agricultural system called "organic" promotes the production of food free of pesticides or any other synthetically produced compost, and aim to obtain safer products to the consumer. However, de Souza Araújo et al (2014) found out organic vegetables been sold in the central market of Pernambuco with Cr, Cu, Fe and Zn contents higher than in the conventionally produced vegetables. analyzed the chemical composition of onions (Allium cepa) and peas (Pisum sativum) produced organically and conventionally in Denmark, and testified the efficiency of elemental composition differentiation for control and authenticity of organic products.…”

“…During the last decades, alternative crop systems have been developed in response to an increasing social pressure for better quality and environmental friendly products (de Souza Araújo et al, 2014). The agricultural system called "organic" promotes the production of food free of pesticides or any other synthetically produced compost, and aim to obtain safer products to the consumer.…”
