“…Community water fluoridation is recognized to play an important part in improving oral health by decreasing the prevalence of dental caries [15]. Further, it is a safe and cost-effective mechanism to decrease dental decay way for large-scale populations [16], but when fluoride level increase in drinking water it may cause tooth fluorosis [17]. The present study gives a clue about the fluoride levels in drinking water in the Asir region of KSA and the occurrence of dental fluorosis.…”

This study was intended to evaluate the fluoride concentration in drinking water and its effect on dental fluorosis in Southwest Saudi Arabia. Water samples were gathered rom wells, filtration plants and commercial brands (bottled water) in distinct urban and rural areas of Asir region of the Kingdom of Saudi Arabia (KSA). Overall, 63 water samples were collected from 12 locations and 9 brands of bottled water. ExStik® FL700Fluoridemeter was used in the analysis of water samples for fluoride levels. The total number of screened patients for dental fluorosis, aged between 9 and 50 years, was 1150; among them, 609 were males and 541 were females. Dean’s index criteria were used to examine the patients for dental fluorosis. The results revealed that fluoride levels varied between 0.03 and 3.8 ppm. People who drank well water displayed increased fluoride levels (>0.81 ppm). The prevalence of dental fluorosis was established to be 20.43% among the total number of examined patients. The findings of this study show very mild to moderate dental fluorosis prevail among the patients who consume well water in the Asir region.

“…Later, they were left absolute (98%) ethanol to send away water molecules with alcohol ones in the pores. As the next step, the samples were placed into vacuum oven (at 50 °C) to get rid of alcohol from the sample without damaging to construction [29]. Subsequently, the dried samples were coated with goldpalladium (40:60) and investigated with JEOL JSM 5600 (Tokyo, Japan) for SEM analysis.…”

Stability of enzymes is significant factor for their industrial feasibility. α-amylase is an important enzyme for some industries i.e., textile, food, paper and pharmaceutics.. Pumice particles (PPa) are non-toxic, natural, low-cost alternative adsorbents with high adsorption capacity. In this study, Cu 2+ ions were attached onto pumice particles (Cu 2+ -APPa). Then, Cu 2+ -APPa embedded composite cryogel was synthesized (Cu 2+ -APPaC) via polymerization of gelforming agents at minus temperatures. Characterization studies of the Cu 2+ -APPaC cryogel column was performed by X-ray fluorescence spectrometer (XRF), scanning electron microscopy (SEM), and Brunauer, Emmett, Teller (BET) apparatus. The experiments were carried out in a continuous column system. α-amylase was adsorbed onto Cu 2+ -APPaC cryogel with maximum amount of 858.7 mg/g particles at pH 4.0. Effects of pH and temperature on the activity profiles of the free and the immobilized α-amylase were investigated, and results indicate that immobilization did not alter the optimum pH and temperature values. kcat value of the immobilized α-amylase is higher than that of the free α-amylase while KM value increases by immobilization. Storage and operational stabilities of the free and the immobilized αamylase were determined for 35 days and for 20 runs, respectively.

“…In inorganic form, arsenic can be found as arsenate, also known as As (V), or can be found as arsenite, referred as As (III) (Sodhi et al, 2019). Arsenate usually predominates in oxygenated water and arsenite in reducing conditions (Gurbuz, Akpınar, Ozcan, Acet, & Odabaşı, 2019). Arsenite is more toxic than arsenate, because it has greater affinity for the sulfhydryl groups, cysteinyl residues of enzymes, and lipoic acids (Sodhi et al, 2019).…”

“…In humans, arsenic is considered a carcinogenic potential (Sodhi et al, 2019;C. Wang, Luan, & Wu, 2019), so, in regions where groundwater is used for public and domestic supply, it is very important to secure the quality of this resource, therefore, to secure that this resource is not contaminated with arsenic (Gurbuz et al, 2019). Chen, Yu, and Belzile (2019) examined the conditions that may affect the speciation of As in water and estimated its solubility and mobility in lakes sediments.…”

“…The toxicity of As is associated with the fact that it is not an essential element for plant growth (Kumar & Kumar, 2019). In humans, arsenic is considered a carcinogenic potential (Sodhi et al, 2019; C.

Arsenic-contaminated waters represent environmental and public health problems. The use of plants has emerged as a viable, cost-effective, and low environmental impact alternative to treat these polluted waters. This review presents studies published in the year 2019 on phytoremediation covering the effects observed on plants, trends in plant species selection and treatment of arsenic-rich biomass. Studies on application of this technology are exposed through constructed (treatment) wetlands, and a brief contextualization on the impacts of arsenic contamination was also performed.
