“…Although individual treatments of salicylic acid and silicon reduced plants free proline, soluble sugars and cadmium uptake and lipid peroxidation rate, they improved root and shoot fresh weights in both cadmium stressed and unstressed seedlings. When combined, salicylic acid and silicon alleviated the inhibitory effects of cadmium on seedlings significantly 28 .…”

Silicon is the most aboundant element in soil and is beneficial for a large variety of plants. It is concentrated in plant tissues in quantities similar to that of macronutrients. Considerable damages to plants caused by abiotic stresses such as drought stress, salinity stress, heavy metal stress and nutrient imbalance, as well as biotic stresses like insect pests and pathogens and even herbivorous attacks, have been reported to be reduced significantly by silicon application. Soil contamination with toxic heavy metals (such as Cd ,Pb.As,Hg, Zn) is becoming a most devasting problem worldwide because of the rapid development of social economy. Silicon significantly improved the growth and biomass of crop plants and reduced the toxic effects of heavy metals after different stress periods. Si treatment ameliorated root function and structure compared with non-treated crop plants, which suffered severe root damage. Silicon plays a substantial role in alleviating heavy metal toxicity in crop plants. Also, silicon may reduce the toxic effects of heavy metals in soil. It may protect the foliage and increase light uptake and reduce respiration. Therefore, in this review, we discussed the effects of silicon on heavy metal stress in especially field crops.

“…33 It has several clinical adverse functions and the most important effect of it is on the oxidative stress mechanism, whereas antioxidants including GSH decrease ROS induced cell damage. 34 According to current guidelines delivered by the Centers for Disease Control and Prevention (CDC), 10 μg/dL of blood Pb levels can be hazardous and proper treatment should be considered. 35 TQ can be a promising substitute for the conventional therapeutic drugs due to its high pharmacological activity and low systemic toxicity.…”

Exposure to food toxins generate multiple adverse health effects. Heavy metals, antibioticsresidue, mycotoxins, pesticides and some food additives are examples of the most importantfood toxins. The common mechanism of toxicity and carcinogenicity effects of food toxins is thegeneration of oxidative stress that leads to DNA damages. Moreover, based on epidemiologicevidence unhealthy eating habits and food toxicities are associated with cancers occurrence.Therefore, application of bioactive food additives as harmless or safe components in foodindustry is expensive. Nigella sativa L. is a broadly used herb-drug for various diseases all overthe world and has been used as preservative and food additive. Based on various studies N. sativahas shown various pharmacological activities including therapeutic efficacy against differenthuman diseases and antioxidant anti-inflammatory effects against environmental toxins. N.sativa decreases the adverse health effects induced by mentioned food toxins via modulating theaction of antioxidant enzymes such as glutathione peroxidase (GPx), glutathione-S-transferasecatalase and act as reactive oxygen species (ROS) scavengers in different organs. Besides, N.sativa and thymoquinone (TQ) have protective effects on food products through removal andinhibition of various toxic compounds. Therefore, in the present review we will describe allprotective effects of N. sativa and its main constituents, TQ, against food induced toxicities.

“…Pb is identified as a cumulative toxicant that is distributed to the brain, liver, kidneys, and bones. It can cause several unwanted effects such as disruption in biosynthesis of hemoglobin resulting in anemia, nervous system damage, increased blood pressure, kidney Volume 12, No 3, May-June 2018; http://www.ijt.ir dysfunction, and miscarriages [11][12][13]. This metal is particularly harmful to infants and young children because of ongoing development of central and peripheral nervous system.…”

Background: Contamination of fruit juices with heavy metals presents a risk for human health. Concentrations of lead, and arsenic in fruit juices of market in Mashhad, Iran, were measured using atomic absorption spectrometry (AAS). Methods: Fifty varieties of commercial fruit juices (grape, apple, orange, pomegranate, and multi-fruit) from 5 popular brands (A, B, C, D and E) were purchased from local markets of Mashhad during spring and winter 2016. Five samples of each brand were analyzed by AAS. Results: The mean concentrations of lead and arsenic were 39.4 and 1.9 ng/mL, with a range of 18.5–54.6 and 1.52-2.35 ng/mL, respectively. The orange A and multi-fruit A samples had a higher lead level than the others, whilst multi-fruit E contained the lowest. The lowest arsenic content was found in grape B, while the highest was found in multi-fruit C. Conclusion: Eighty-three percent of the samples had lead levels exceeding the maximum level (30 ng/mL) accepted by the Codex Alimentarius Commission, while arsenic levels were below the maximal permissible value (10 ng/mL). Due to the fact that fruit juices are used by all age groups including infants and children, it is necessary to minimize the health risk from heavy metal contamination in fruit juices. For this reason, the amount of heavy metals contaminants in fruit juice samples should be regularly checked and controlled by the local health authorities.
