“…All the results quoted by Mikulewicz et al (2014) were higher than for group E presented herein. This higher contents of Cr in Control group C2 than in the control group from the quoted study can be accounted for by a different domicile of the individuals under study (Wrocław vs Kraków), among others by air pollution and different composition of drinking water [ 27 ].…”

The ObjectiveThe aim of the study was evaluation of metal ions (nickel and chromium) released from orthodontic appliances in cleft lip and palate patients and the usefulness of non-invasive matrices (saliva and hair).Materials and MethodsThe material studied consisted of 100 individuals, including 59 females and 41 males of 5 to 16 years of age, which were divided into 3 groups: experimental–patients with cleft lip and palate (36 individuals, the average treatment time 5.74 years); control group–patients without cleft lip and palate, during orthodontic treatment (32 individuals, the average treatment time 1.78 years) and the control group patients without cleft lip and palate, without any orthodontic appliances (32 individuals). Samples (saliva, hair) were collected and subjects underwent a survey by questionnaire. Multi-elemental analyses of the composition of non-invasive matrices was conducted in an accredited laboratory by inductively coupled plasma spectrometry technique ICP-OES. The results were reported as mean contents of particular elements (Cd, Cr, Cu, Fe, Mn, Mo, Ni, Si) in hair and in saliva.ResultsThe concentration of Cr, Ni, Fe and Cu ions in saliva of cleft lip and palate patients were several times higher as compared with not treated orthodontically control groups and higher than in the group with orthodontic appliances. Among the assessed matrices, hair of cleft lip and palate patients seem to be not a meaningful biomarker.ConclusionIt was found that orthodontic appliances used in long-term treatment of cleft lip and palate patients do not release toxic levels of Cr and Ni ions.

“…Many other signs and symptoms have also been reported in Bangladesh, i.e., chronic cough, crepitating in the lungs, diabetes mellitus, hypertension, and weakness [30]. Inorganic As in drinking water is generally found in >95% of total As, which can be absorbed easily in the gastrointestinal tract [31]. Approximately 80-100% of inhaled and ingested As is absorbed through the gastrointestinal tract and lungs, but up to 50-70% of the absorbed As is gradually eliminated by methylation in the kidneys through urine.…”

The arsenic (As) hazardous quotient was estimated based on concentration of As in drinking water and scalp hair of male subjects of two age groups (n=360) consuming As contaminated water at different levels and non-contaminated drinking water. The total As concentrations in drinking water of less-exposed (LE) and high-exposed (HE) areas was found to be 3- to 30-fold higher than the permissible limit of the World Health Organization (2004) for drinking water, while the levels of As in drinking water of non-exposed (NE) areas was within the permissible limit. The levels of As in scalp hair samples of male subjects of two age groups belonging to NE, LE, and HE areas ranged from 0.01 to 0.27, 0.11-1.31, and 0.36-6.80 μg/g, respectively. A significant correlation between As contents of drinking water and As concentration in scalp hair was observed in sub-district Gambit (r=0.825-0.852, p<0.001) as compared to those subjects belonging to LE sub-district Thari Mirwah. A toxicity risk assessment provides a hazard quotient corresponding to <10 that indicates non-carcinogenic exposure risk of understudy areas.

“…The referent subjects have no remarkable dermatological symptoms, whereas, exposed subject of both genders have different physiological disorders such as, breathing, gastrointestinal, and skin disorders. Some skin diseases with severe itching on exposure to sunlight have been reported [32,33]. On the other hand, our survey demonstrated that the people of the studied towns have poor socioeconomic status.…”

“…The clinical investigations were most decisive to identify the chronic As toxicity, which may induce harmful effects to various organs of the human body [32]. The referent subjects have no remarkable dermatological symptoms, whereas, exposed subject of both genders have different physiological disorders such as, breathing, gastrointestinal, and skin disorders.…”

The effects of arsenic (As) toxicity due to frequent consumption of arsenic-contaminated fish was estimated by the analysis of scalp hair of adult males, living near arsenic-contaminated area of Pakistan. For comparison purposes, scalp hair samples were also collected from the inhabitants of Hyderabad city consuming fish species with low levels of As, collected from Indus River. Concentration of As in scalp hair samples was analyzed by using hydride generation atomic absorption spectrometry (HG AAS), after microwave-assisted acid digestion. The accuracy of the As measurement was tested simultaneously analyzing certified reference material. The concentration of As in muscle tissues of fish species were found in the range of 2.11 to 14.1 μg/g and 1.92 to 12.2 μg/g, collected from arsenic-contaminated and noncontaminated areas, respectively. Exposed subjects had significantly elevated levels of As in scalp hair samples (0.72-4.94 μg/g) as compared with referent subjects (0.21-1.484 μg/g; p < 0.01). The As levels in scalp hair was positively correlated with As levels in fish.
