“…The effect of different herbicides on phenylalanine ammonia-lyase activity and therefore on phenolic biosynthesis has also been reported (Tomas-Barberan and Espin 2001). Moreover, applications of pesticides for pest control leads to fruit pesticide residues that may exceed the maximal level (Chavarri et al 2004;Tsakiris et al 2004); however, none of the farming choices (conventional, IPM, organic) available on the market are completely free of pesticide residues (Baker et al 2002).…”

Tomato (Solanum lycopersicum) health components: from the seed to the consumer

It is widely accepted that a healthy diet is an important factor in preventing chronic diseases, and in improving energy balance and weight management. Studies have shown strong inverse correlations between tomato consumption and the risk of certain types of cancer, cardiovascular diseases and age-related macular degeneration. Because tomato is the second-most important vegetable in the world after potato, this horticultural crop constitutes an excellent source of health-promoting compounds due to the balanced mixture of minerals and antioxidants including vitamins C and E, lycopene, b-carotene, lutein and flavonoids such as quercetin. Improvement in phytonutrients in tomatoes can be achieved by cultivar selection, environmental factors, agronomic practices, stage of ripeness at harvest, and appropriate handling and conditioning all the way from the field to the consumer. The purpose of this paper is to review the recent literature of the main factors that can improve the nutritional quality of tomato and consequently their beneficial role in human diet. The importance of genotype selection and the optimization of environmental conditions (light, temperature, humidity, atmospheric CO 2 and air pollutants) for high nutritional value is outlined first, followed by the optimization of agricultural practices (soil properties, water quality, mineral nutrition, salinity, grafting, pruning, growing systems, growth promoters, maturity, and mechanical and pest injuries). The review concludes by identifying several prospects for future research such as modelling and genetic engineering of the nutritional value of tomato.

“…To minimize the negative effects that conventional apple production pose to the environment and human health, some alternative cultivation systems have been developed (Tsakiris et al 2004). Integrated pest management (IPM) is a sensitive approach that relies on current, comprehensive information on the life cycles of pests and their interaction with the environment.…”

This paper describes method validation for determination of more than 40 pesticides in apples using a GC technique. Target compounds belonged to the organochlorine, organophosphorus, carbamates, pyrethroids, triazoles, dicarboximides and strobilurins groups, among others. Sample preparation consisted of acetone extraction and subsequent cleanup/concentration by SPE with a polymer-based sorbent. Single quadrupole GC-MS operating in SIM mode and electron impact ionization was used for identification and quantification of the pesticides. Average recoveries for analytes ranged between 70 and 110% at three fortification levels - 0.01, 0.1 and 0.2 mg kg(-1). Relative standard deviations were lower than 20% for all tested compounds. Calculated limits of detection and limits of quantification were below 0.01 mg kg(-1), which were sufficiently low compared to the maximum residue levels (MRLs) established by European legislation. The proposed method was applied for determination of pesticide residue in four selected apple varieties after harvesting. Whole and processed fruits (peel and peeled fruits) were analyzed from different treatment systems: two conventional, one based on integrated pest management (IPM) and two variants based on organic production (controls). Higher levels of pesticide residues were found in apple fruits under conventional conditions. Fenitrothion and chlorpyrifos residues were detected frequently in apple peel at concentrations up to 0.45 and 0.77 mg kg(-1), respectively. The levels found in the whole fruits of the same samples were much lower than in peel and below the respective MRLs (0.5 mg kg(-1) for both pesticides). Measurable residues of triadimenol only, up to 0.05 mg kg(-1), concentrated in the peel, were found in the apples from IPM.

“…Moreover, the use of insecticides varies each year correspondingly to the number of insect infestations. According to the latest published reports for pesticides residues in conventional cultivations of peaches (Tsakiris et al, 2004), the detected levels of parathion methyl, malathion and chlorpyrifos residues in samples from ICM were significantly lower than the corresponding one in conventional cultivations. Phosmet, phosalone and clorothalonil were also detected in conventional cultivations of peaches but in such levels which bear no statistical significant difference to the corresponding one in ICM.…”

“…This assessment was based on estimation of the amount, the fate and the inherent toxicity of active ingredients applied, and (c) the evaluation of ICM as an alternative solution to methyl bromide and waste management in vegetables (Anton, Castells, Montero, & Huijbregts, 2004;Giannakou & Karpouzas, 2003;Margaritopoulos et al, 2007). Dinham (2003) and Tsakiris et al (2004), support a series of advantages of ICM regarding different aspects, in production (reduced pesticide use, lower pesticide residues), in public health and the environment (safer products for consumers) and in workers' safety (reduced risk of applicators' exposure). A focused series of articles has also been published that discuss the exposure of field workers during treatments and the levels of residues remaining on the foliage (Spencer et al, 1995;Staiff, Somer, & Foster, 1975).…”
