This study aims to investigate the content of lead and cadmium in most frequently used brands of cosmetic products (lipstick and eye shadow) in Iran. Fifty samples of lipstick (5 colors in 7 brands) and eye shadow (3 colors in 5 brands) were selected taken from large cosmetic stores in Isfahan (Iran) and lead and cadmium of them were analyzed. The results showed that the concentration of lead and cadmium in the lipsticks was within the range of 0.08–5.2 µg/g and 4.08–60.20 µg/g, respectively. The eye shadow samples had a lead level of 0.85–6.90 µg/g and a cadmium level of 1.54–55.59 µg/g. The content range of the heavy metals in the eye shadows was higher than that of the lipsticks. There was significant difference between the average of the lead content in the different brands of the lipsticks and eye shadows. Thus, the continuous use of these cosmetics can increase the absorption of heavy metals, especially Cd and Pb, in the body when swallowing lipsticks or through dermal cosmetic absorption. The effects of heavy metals such as lead can be harmful, especially for pregnant women and children. Therefore, effort must be made to inform the users and the general public about the harmful consequences of cosmetics.

Introduction. Changes in the body of children and adolescents aimed at adapting to environmental factors are determined by genetic polymorphism in xenobiotic biotransformation genes, determining the degree of susceptibility of the child’s body to pollutants, which is the basis of modern personalized preventive medicine when managing risks to the health of the child population under the influence of environmental factors. Material and methods. Trace elements, including heavy metals, lead and cadmium, were determined in the hair of 256 practically healthy teenagers by atomic absorption spectrophotometry. Depending on the level of content of the latter, two groups of adolescents were formed to determine six genes of the cytochrome P-450 family. Group 1 consisted of adolescents whose cadmium lead content exceeded the average Russian indices. The second group included adolescents whose heavy metals were above the level of average Russian standards. Results. Studies have shown that in adolescents of the 1st group, compared with the data of adolescents of the 2nd group, an increase in the number of carriers of two mutant alleles at the locus rs 1048943 (gene CYP1A1) is 3.08 times, rs 464621 (gene CYP1A1) is 1. 8 times; locus rs 2069522 (CYP1A2 gene) 3.63 times; locus rs 1799853 (CYP2C9 * 2 gene) 4.5 times; locus rs 1057910 (gene CYP2C9 * 3) 3.8 times and locus rs 2279343 (gene CYP2B6) 4.25 times. Moreover, carriers of two normal alleles in adolescents of the first group at the locus rs 1048943 (gene CYP1A1) were 5.14 times; locus rs 2279343 (CYP2B6 gene) was 6.5 fold less than among adolescents of the 2nd group; and at the locus rs 464621 (gene CYP1A1), rs 2069522 (gene CYP1A2), rs 1799853 (gene CYP2C9 * 2), rs 1057910 (gene CYP2C9 * 3) there were no carriers of normal homozygotes. Conclusion. Group 1 adolescents with heavy metal contamination of the body are carriers significantly in a greater number of pathological mutations in the genes of the cytochrome P-450 detoxification system in comparison with data from group 2 adolescents.

The samples were digested by wet digestion technique .The trace element were determined using bulk scientific model VPG 210 model  Atomic Absorption Spectrophotometer (AAS).. The concentration of the determined heavy metal were The result revealed that Cr,  Ni and Cd were not detected in milk samples from Kawo, Malali  and Kudendan whereas lead (Pb) is detected in all samples and found to be above  the stipulated limits of recommended dietary allowance (NRC,1989) given as 0.02mg/day. Cu and Zn are essential elements needed by the body for proper metabolism and as such their deficiency or excess is very dangerous for human health. However, they were found in all samples and are within the recommended limits while Cd (2.13 – 3.15 mg/kg) in milk samples from Kakuri was found to be above such limit (0.5mg/day). Cow milk samples analyzed for heavy metals in this research work pose a threat of lead and cadmium toxicity due to their exposure to direct sources of air, water and plants in these grazing areas, thereby, resulting to a potential health risk to the consumers.

Air pollution gives a negative impact to human health due to pollutants released by motor vehicles. From the several kinds of pollutants generated, CO is one of the most pollutants released by motor vehicles. Lead can contaminate the environment and can poisoning the living organisms. Lead can cause various disorders to the body and also organs such as hematopoietic system, neurological, endocrine, renal, gastrointestinal, hematological, and reproduction. This study aims to analyze the comparison of the levels of lead (Pb) in fried foods sold on Jalan Sam Ratulangi with fried foods sold on the edge of Jalan Purwodadi, Pekanbaru City. This research is descriptive quantitative. Samples in the form of bakwan which were taken by one trader by using a total sampling of 6 samples. The sample will then be examined quantitatively to determine the level of lead in the sample using the atomic absorption spectrophotometric method. The results of the lead level examination will then be compared with the maximum limit of metal contamination according to the standards set by the Directorate General of Drug and Food Control No. 00.06.1.52.4011 Year 2009 to find out whether the fried foods sold in that location meet the Threshold Value (NAB), and compared using the SPSS t test. The results of the research after analysis using the t test, it is known that the p value is 0.216 when compared with a= 0.05, then p>a, so there is no significant difference between the fried foods sold on Jalan Sam Ratulangi and Purwodadi, Pekanbaru City, all samples exceed The threshold value set by the Regulation of the Director General of Drug and Food Control Number HK.00.06.1.52.4011 of 2009 is 0.25 mg/kg.

The results of studying the effects of water-alcohol infusions of medicinal plants - rhizomes of thick-leafed incense (Bergenia crasslifolia L. Fritsch), dioica nettle leaves (Urtica dioca L.), burdock roots (Arctium lappa L.), and mother-and-leaf leaves - are presented. ordinary machichi (Tussilago farfara L.) on the organism of laboratory rats under conditions of short-term intoxication with heavy metals in doses of 25 mg of lead and 2.5 mg of cadmium per 1 kg of live weight. In the course of studies it was found that the effect of heavy metals on the body of laboratory animals is selective - the main “depot” of lead was bone tissue, and cadmium - the kidneys and liver. The addition of 1 ml of water-alcohol infusions from medicinal raw materials to the diet of rats as detoxicants caused a decrease in the level of lead in the animal organism to 6.32 times, cadmium to 3.46 times. The greatest detoxification ability was shown by infusions of the roots of burdock and leaves of nettle dioecious. Under the influence of elevated doses of lead and cadmium in laboratory animals there was an increase in heart mass by 40.34 % and spleen by 89.91 %, a decrease in the content of alkaline phosphatase in blood serum by 25.81 %. Water-alcohol infusions normalized the biochemical parameters of rat blood serum. Studies have shown that the infusions of rhizomes of thick-leafed frangipani, burdock roots, dioecious nettles and coltsfoot leaves with antioxidant properties can be the basis for the development of an effective herbal preparation used for the prevention and treatment of animals from intoxication with salts of heavy metals.

Cadmium And Lead

Every year, pollution by eco-toxicants of natural and anthropogenic origin is becoming more and more acute. Some of the most toxic among them are heavy metals, especially cadmium and lead. These elements do not decompose. Once released into the environment, these elements continue to circulate in water, soil, and air for a very long time, accumulating in plants and livestock products. Therefore, there is a problem of obtaining safe agricultural products in areas contaminated with heavy metals. In animal husbandry, synthetic and natural enterosorbents are used for obtaining safe products. For example, such enterosorbents are shungites, bentonites, diatomites, clays. We tested diatomite from the Kamyshlovskoye deposit at a dose of 5.0 g/kg of feed to reduce cadmium accumulation and lead during their combined intake. We investigated the feed intake of a combination of cadmium and lead at doses of 5.0 and 50.0 mg/kg feed. The result of this experiment is the accumulation of metals in the liver, kidneys, and bones, and, in addition, in the testes. The use of diatomite to reduce the accumulation of heavy metals has not been successful. There is an increase in lead accumulation in the liver, kidneys, and testes. The content of cadmium in diatomite is 3.86 ± 0.20 mg/kg, lead – 105.0 ± 7.2 mg/kg. The results obtained indicate that diatomite as a feed additive to reduce lead and cadmium intoxication did not show protective properties.

Abstract. Madhi QH, Abass MH, Matrood AAA. 2021. The efficiency of some bioagent fungi in reduction of wheat seed decay and seedling damping-off disease with heavy metals interaction. Biodiversitas 22: 3984-3993. Biological control is an ecofriendly efficient measurement for disease control and heavy metals reduction in soils. The use of bioagent fungi such as Trichoderma koningii and Chaetomum globosum reduced the negative effect of pathogenic fungi that cause seed decay and the seedlings damping off wheat alone or by interaction with the concentrations of lead or cadmium, which increases the germination percentage of wheat seeds and reducing seedling damping off. It also reduced the severity index of wheat with pathogenic fungi and reduced the negative effect of interaction between heavy metals and pathogenic fungi on the severity index of the wheat.  Results showed that T. koningii and C. globosum reduced the effect of the interaction of R. solani with 200 mg/kg lead to 57.7 and 55.4%, respectively and R. solani and cadmium 3 mg/kg with 60 and 61.6%, respectively. T. koningii and C. globosum also reduced the effect of the interaction  F.solani with lead 200 mg/kg to 45.4 and 48.5%, respectively and  F. solani and cadmium 3 mg/kg to 46.8 and 52.5% respectively. The bioagent fungi also increased the fresh and dry weight of shoot and root system, T. koningii significantly increased the fresh and dry weight of shoot in the presence of R. solani. The results also indicated that there was a high significant difference in the use of C. globosum in increasing the fresh and dry weight of shoot and root system. T. koningii and C. globosum significantly reduced the effect of interaction between the pathogenic fungi and low concentrations of lead and cadmium leading to an increase in the fresh and dry weight of shoot and root system. They also increased the plant height in the presence of pathogenic fungi as well as reducing the negative effect of the interaction between heavy metals and pathogenic fungi in the height of wheat plants. No significant interaction was observed between the low concentrations of lead and cadmium and pathogenic fungi in the presence of bioagent fungi. The results exhibited that bioagent fungi can reduce the negative effect of interaction of pathogenic fungi with lead and cadmium on the total phenols content of wheat leaves, and no significant difference was recorded in the treatment of low concentrations with the pathogenic fungi. Results showed that bioagent fungi can reduce the negative effect of the interaction of pathogenic fungi with lead and cadmium on the total phenols content of wheat plant leaves. No significant differences were recorded in the treatment of low concentrations with the pathogenic fungi in the presence of bioagent fungi. The two bioagent fungi increased the concentration of chlorophyll a and b, total chlorophyll and carotenoids reduced anthocyanin in leaves, and increased chlorophyll stability index compared to the control treatment.

We measured changes in atmospheric and blood levels of lead and cadmium in the South Korean general population during the past decade. Blood data of 16,873 adults were taken from the Korean National Health and Nutrition Examination Survey (KNHANES, 2008–2017). Atmospheric data were taken from 66 air quality monitoring sites in 16 different regions in South Korea. From 2008 to 2017, the geometric mean (GM) blood lead level decreased from 2.37 to 1.46 μg/dL (38.4% decrease), and the atmospheric lead concentration decreased by 61.0% in the overall population. During this time, the GM blood cadmium level decreased from 0.88 to 0.72 μg/L (18.2% decrease), and the atmospheric cadmium concentration decreased by 63.6%. Multiple linear regression analysis indicated that a half reduction in air lead was associated with a 0.09 μg/dL decrease in blood lead (95% CI: 0.03 to 0.15) in a subgroup of the metropolitan city population. However, a half reduction in air cadmium had no significant effect on blood cadmium. Multiple linear regression analyses indicated that the decrease in blood lead level over 10 years in Korea was related to the decrease in atmospheric lead concentration. However, the decrease in blood cadmium level during this time was not significantly associated with the decrease in atmospheric cadmium concentration. Our findings suggest that inhalation is a major source of lead exposure, but not of cadmium exposure. Ingestion of dietary cadmium presumably has a stronger impact on blood cadmium levels.

Background. There has been concern on the likelihood of contamination of infant formulae and consequent health risk in children. Objective. This study has assessed and compared the lead and cadmium levels in infant formulae commonly consumed in Nigeria with international regulatory limits. It has also compared the estimated daily intake with Joint FAO/WHO Expert Committee on Food Additives (JECFA) and Proposition 65 Provisional Tolerable Daily Intake. Material and Methods. Lead and cadmium levels in 26 different brands of infant formulae purchased from stores in Port-Harcourt, Rivers state, Nigeria in January 2018 were assayed by Atomic Absorption Spectrophotometry. Results. The lead and cadmium levels in milk based infant formulae ranged from 0.61-3.50 mg/kg and 0.01-0.55 mg/kg respectively whereas the range of the lead and cadmium levels in the cereal and cereal mix based were 0.29-1.95 mg/kg and 0.02-0.37 mg/kg, and 0.47-2.34 mg/kg and 0.001-0.46 mg/kg respectively. The mean lead level in the milk-based formulae (1.49 0.89 mg/kg) was slightly higher than other groups of formulae but the difference was not significant (p<0.05). The mean level of cadmium (0.17 mg/kg) in milk-based infant formulae was higher than levels in cereal and cereal mix but there was no significant statistical difference (p<0.05) between the samples. The lead and cadmium level in milk, cereal and cereal mixed based infant formulae were above the food safe limits. Conclusions. The consumption of infant formulae may add to the body burden of cadmium and lead of children with attendant public health implication. Regular monitoring and safety assessment of metals contamination of these infant formulae is advised.

Fruits play important role in providing the individuals daily dietary needs from vitamins, iron, and some metals that are needed in the body as dietary supplement or as an important element that form some hormones or enzymes in small concentrations, if exists in high concentrations become toxic with side effects. The presence of heavy metals such as of Fe, Cd, Pb, Cr, Mn, Ni, Co, and Zn in Ximenia americana and sclerocarya birrea wild fruits were determined using standard methods such as AAS. Results obtained from this study revealed that the concentration of the metals in sclerocarya birrea was Iron, (8.83 ± 0.10) Cadmium (0.01 ± 0.00) Lead (0.04 ± 0.02) Chromium (0.19±0.10) Manganese (4.27 ± 0.20) Nickel (0.21 ±0.10) Cobalt (0.09 ±0.01) and Zinc (2.96 ± 0.02) mg/g. On the other hand, Ximenia americana content was Iron, (6.37 ± 0.10) Cadmium (0.02 ± 0.01) Lead (0.01 ± 0.00) Chromium (0.24±0.01) Manganese (2.50 ± 0.10) Nickel (0.29 ±0.10) Cobalt (0.17 ±0.00) and Zinc (2.31 ± 0.06) mg/g respectively. Highest concentration of Iron was recorded as (8.83 ± 0.10) mg/g in the sclerocarya birrea sample analyzed, while Lead and Cadmium were found to be the least with concentration of (0.01 ±0.00) mg/g in both samples. Their concentrations are within the maximum allowable concentration (MAC) set by FAO/WHO. The findings of this study reveal that there are no health risks associated with the consumption of heavy metals through the intake of these two fruits.

To reduce the risk of accumulation of heavy metals in the meat of fattened young cattle successfully used adsorbents that bind toxins and removed from the digestive tract. The detoxification effect of adsorbents increases with the skillful selection of enzyme preparations due to the synergy of action. The aim of the research is to study the effect of toxfin adsorbent and the enzyme preparation celloviridin G20x in the diets with high content of heavy metals on the morphological and biochemical composition of the blood of fattened bulls. According to the principle of pairs-analogues (taking into account the origin, sex, age, live weight) were formed 4 groups of 10 heads each. The research material is processed statistically using the software package «Microsoft Excel». In the composition of the winter diet of animals of all groups there was an excess of maximum permissible concentrations (MPC) in zinc level by 67.3-67.5 %, lead -by 63.4-64.6 % and cadmium - by 62.9-63.1 %, in the summer diet - by 66.4-66.6 %, 61.4-61.6 % and 60.6-60.8 %. This article presents experimental material showing that to optimize the morphological and biochemical composition of blood and increase the detoxification effect in the body of bulls on fattening should be in the diet with high levels of heavy metals together to introduce IEC celloviridin G20h at a dose of 70 g/t feed and adsorbent toxfin at a dose of 1 kg/t feed. At the same time, animals of the 3rd experimental group showed improvement of morphological and biochemical composition of blood and optimization of protective properties of their organism. The highest detoxification effect was obtained by co-feeding the tested drugs, so that in the blood of bulls of the 3 experimental group there was a significant (P<0.05) decrease in the concentration of zinc by 2.23 times, lead by 2.43 and cadmium by 3.00 times. At the same time, in no case in animals of the 3 experimental group in the blood there was no excess of MPC in terms of zinc, lead and cadmium.
