Abstract
Aluminum is ingested through foods, water, air, and even drugs. Its intake is potentiated further through foods and tea prepared in aluminum utensils and Al salt added in the drinking water for removal of suspended impurities and also fluoridein the affected areas. The ameliorating role of a blue green alga Spirulina is well documented to various pollutants in the animal models. We, therefore, examined its protective role (230 mg/kg body weight) on the hematology of male Swiss albino mice treated with aluminum (sub-acute = 78.4 mg/kg body weight for 7 days, sub-chronic = 7.8 mg/kg body weight for 90 days) and aluminum fluoride (sub-acute = 103 mg/kg body weight, sub-chronic = 21 mg/kg body weight), along with their recovery after 90 days of sub-chronic exposure. This study revealed significant reduction in the values of RBC (5-18 %), Hb (15-17 %), PCV (8-14 %), and platelets (26-36 %), and increase in WBC (54-124 %) in the treated mice, particularly after sub-acute exposure. Aluminum fluoride was comparatively more toxic than aluminum. Further, Spirulina supplement not only alleviated toxicity of test chemicals in Swiss albino mice but also led to their better recovery after withdrawal.

Study of potential transfer of aluminum to the brain via the olfactory pathway.
Many employees in the aluminum industry are exposed to a range of aluminum compounds by inhalation, and the presence of ultrafine particles in the workplace has become a concern to occupational health professionals. Some metal salts and metal oxides have been shown to enter the brain through the olfactory route,

Effect of high fluorine (F) intake on tissue lead (Pb) concentrations
Four groups of 10 male, albino Sprague Dawley rats receiving either deionized water or deionized water containing 300 parts per million (ppm) F as NaF, 200 Pb as Pb acetate or F+Pb at 300 and 200 ppm, respectively, as drinking water for 10 weeks were fed a casein-based purified diet.

Thyroid function tests in aluminum potroom workers exposed to fluoride emissions.
Following a previous study on parathyroid hormone determinations in 200 aluminum potroom workers, we conducted a cross-sectional survey of 116 (58%) of these workers for their levels of serum triiodothyronine (T3), tetraiodothyronine (T4), thyroid stimulating hormone (TSH), urinary creatinine, and preshift urinary fluoride (F). The mean serum TSH measured by

Fluoride increases lead concentrations in whole blood and in calcified tissues from lead-exposed rats.
Higher blood lead (BPb) levels have been reported in children living in communities that receive fluoride-treated water. Here, we examined whether fluoride co-administered with lead increases BPb and lead concentrations in calcified tissues in Wistar rats exposed to this metal from the beginning of gestation. We exposed female rats and

Using drawing tests to measure intelligence in children from areas impacted by combined Al-F endemic toxicosis (Shuicheng, Guizhou).
Measurements of intelligence via drawing tests have been conducted to examine the intelligence development of children from regions affected by combined AIF endemic toxicosis. A selected number of 196 children between 6.5 and 12 years of age participated in the testing. Across all age groups, the average IQ level of children from

Factors which increase the risk for skeletal fluorosis
The risk for developing skeletal fluorosis, and the course the disease will take, is not solely dependent on the dose of fluoride ingested. Indeed, people exposed to similar doses of fluoride may experience markedly different effects. While the wide range in individual response to fluoride is not yet fully understood, the following are some of the factors that are believed to play a role.

Fluoridation, Dialysis & Osteomalacia
In the 1960s and 1970s, doctors discovered that patients receiving kidney dialysis were accumulating very high levels of fluoride in their bones and blood, and that this exposure was associated with severe forms of osteomalacia, a bone-softening disease that leads to weak bones and often excruciating bone pain. Based on

Fluoridation of drinking water and chronic kidney disease: Absence of evidence is not evidence of absence
A fairly substantial body of research indicates that patients with chronic renal insufficiency are at an increased risk of chronic fluoride toxicity. Patients with reduced glomerular filtration rates have a decreased ability to excrete fluoride in the urine. These patients may develop skeletal fluorosis even at 1 ppm fluoride in the drinking water.
