The main of this data was determine the concentrations and health risks of fluoride in 66 drinking water samples collected from villages of the Iranshahr city, Sistan and Baluchestan Province in Iran. Fluoride concentration was measured by the standard SPADNS method. Data indicated that fluoride concentration in drinking water ranged from 0.25 to 1.72 mg L and average of fluoride concentration was 0.27 mg L. The mean estimated daily intake (EDI) values for fluoride in different groups of infants, children, teenagers and adults were 0.0021, 0.0151, 0.0107 and 0.0086 mg/kg, respectively. Also, risk assessment data indicated that hazard quotient (HQ) value of groundwater samples is more than 1 in 6% of groundwater samples in age groups of children and teenagers.

The 2021-eruption of Tajogaite (La Palma, Canary Islands) was associated with the formation of large amounts of respirable PM aerosols (smaller than 10 μm) that triggered air quality crisis and lockdowns for ∼35,000 persons. This study aims to quantify the contribution of the aerosol formation mechanisms to the volcanic PM concentrations. During the eruption and post-eruption, we monitored trace gases (SO, HF, HCl and NO), and the size distribution and chemical composition of falling-tephra and PM aerosols.

This study aimed to evaluate fluoride concentrations in a variety of commonly consumed teas and Herbal infusions in Brazil and assess potential Health risks associated with their ingestion. A total of 21 samples were analyzed, including 12 loose-leaf and 9 commercially bagged products. Fluoride quantification was performed using a validated spectrophotometric method, and a deterministic and probabilistic human Health risk assessment was conducted.

Methane (CH), carbon dioxide (CO), and oxygen (O) are the major gases produced by dairy cattle as a result of rumen fermentation and metabolism, and thus, their concentrations are frequently measured as a way of estimating heat production and energy metabolism. A well-utilized method of measuring gas consumption and production to estimate heat production is indirect calorimetry, which requires bags to retain the sampled gases until analysis. The objective of this study was to determine the ability of a polyvinyl fluoride gas bag (PF) and a multilayer fabrication gas bag containing an aluminum layer (NAP) to maintain respiratory gas composition in comparison to a polyethylene terephthalate bag (PET).

Cemented paste backfill has made outstanding contributions to the large-scale consumption of phosphogypsum (PG), but poor water resistance significantly weakens the mechanical strength, promotes the leaching of total soluble phosphate (TP) and fluoride ions (F), and reduces its attractiveness in mine engineering. This research synthesized a curing agent (CA) using sodium methylsilicate, sodium silicate, and polyaluminum chloride (PAC). PG produced from Deyang Haohua Qingping Phosphate Mine Co.

These drugs inhibit the synthesis and release of prostaglandins (PGs) in the neurons of the anterior hypothalamus and exert therapeutic effects as a consequence. However, these drugs are relatively commonly misused and abused, often owing to a lack of proper medication guidance.
