“…One explanation for higher levels of heavy metals in conventional than organic crops and crops based food might be the higher levels of Cd, copper and Zn in inorganic fertilizers that commonly have been used, although presence of heavy metals in conventional fertilizers has been reduced during recent years [139]. Similarly as for the nutritional compounds discussed above, a large variation in heavy metal accumulation among genotypes, also when organically grown, have been reported [140]. …”

An increasing interest in organic agriculture for food production is seen throughout the world and one key reason for this interest is the assumption that organic food consumption is beneficial to public health. The present paper focuses on the background of organic agriculture, important public health related compounds from crop food and variations in the amount of health related compounds in crops. In addition, influence of organic farming on health related compounds, on pesticide residues and heavy metals in crops, and relations between organic food and health biomarkers as well as in vitro studies are also the focus of the present paper. Nutritionally beneficial compounds of highest relevance for public health were micronutrients, especially Fe and Zn, and bioactive compounds such as carotenoids (including pro-vitamin A compounds), tocopherols (including vitamin E) and phenolic compounds. Extremely large variations in the contents of these compounds were seen, depending on genotype, climate, environment, farming conditions, harvest time, and part of the crop. Highest amounts seen were related to the choice of genotype and were also increased by genetic modification of the crop. Organic cultivation did not influence the content of most of the nutritional beneficial compounds, except the phenolic compounds that were increased with the amounts of pathogens. However, higher amounts of pesticide residues and in many cases also of heavy metals were seen in the conventionally produced crops compared to the organic ones. Animal studies as well as in vitro studies showed a clear indication of a beneficial effect of organic food/extracts as compared to conventional ones. Thus, consumption of organic food seems to be positive from a public health point of view, although the reasons are unclear, and synergistic effects between various constituents within the food are likely.

High-yielding rice cultivars with good processing quality and rich in nutrition suitable to a changing climate are of particular importance for future rice-based food production. Here, seven Rwandan rice cultivars were grown in a climate chamber of the biotron facility at the Swedish University of Agricultural Sciences, to be evaluated for their grain yield, nutritional composition, and dough mixing properties. Two di erent levels of inorganic fertilizer were applied weekly from the seedling stage until owering. Signi cant di erences for grain yield and quality attributes were found between cultivars. Jyambere showed signi cantly the highest yield while Ingwizabukungu, Nemeyubutaka, and Jyambere were high in mineral elements content. Ndamirabahinzi and Mpembuke had the highest levels of TPC and TAC. Generally, the lower fertilizer dose resulted in a better performance of the cultivars for both yield and quality attributes. Signi cantly higher content of Fe, Ca, and Ba was found in grains from the moderate fertilizer dose, whereas K, Na, P, S, Zn, Cd, and Pb increased in grains from the higher fertilizer dose. e cultivar Ndamirabahinzi showed less variability of evaluated characters across fertilizer doses. e results from this study may be used for rice breeding of cultivars with high yield and good grain quality.

“…Wheat belongs to non-hyperaccumulators, but still accumulates high amount of heavy metals, especially in grains [10]. Besides, plant genotypes differ in their uptake, translocation, accumulation of trace metals [4], and similar phenomenon was observed in wheat plants and asparagus bean cultivars [9,22]. Recently, Hansi et al found, in lab, that the concentration of Cu in barley shoot would reduce with increasing planting density [8].…”

In order to investigate the effects of planting density on accumulation of heavy metals in spring wheat, a weak alkaline agricultural district mainly contaminated by heavy metals Cu, Zn, Pb and Cd, was chosen in 2014. Five planting densities (114×10 4 , 174×10 4 , 249×10 4 , 369×10 4 and 519×10 4 plants hectare -1 , respectively) were designed and the level of heavy metals in soil and in various parts (root, stem, leaf, husk and grain) of spring wheat were detected, and then the health risk to human health was assessed via hazard quotient. The results indicate that concentrations of Pb and Cd in each part of spring wheat plant are negatively correlated with planting density, similar but weaker trends are observed for those of Cu and Zn. The hazard quotient of heavy metals through food chain is markedly reduced with increasing planting density, especially for Pb and Cd at higher planting densities (369×10 4 and 519×10 4 plants hectare -1 ). Conclusively, the present study shows that suitable planting density could be a feasible cultivation method for ensuring the safety of wheat products and human health on slightly polluted alkaline soils.
