Abstract Numerous population-based studies have documented high prevalence of aflatoxin associated childhood stunting in low income countries. We provide an estimate the disease burden related using data from four African For this empirical analysis, we obtained blood albumin adduct biomarker based exposure as measured ELISA technique and anthropometric measurement surveys done over a 12-year period 2001 to 2012 countries Africa. used these calculate population attributable risk (PAR), life...
Abstract. To explore the possibility of fluoride toxicity, 747 water samples were collected from surface and groundwater sources 16 major cities Pakistan, adopting a uniform sampling design with distribution samples: Lahore (79), Kasur (46), Faisalabad (30), Khushab (50), Chakwal (51), Mianwali Jhelum (53), Bahawalpur (60), Karachi Mirpur Khas (55), Peshawar (38), Risalpur (35), Quetta (81), Ziarat (21), Loralai Mastung (37). Comparison analytical findings WHO Guidelines Drinking Water for...
Abstract. Arsenic is a non-metallic constituent, present naturally in groundwater due to some minerals and rocks. not geologically uncommon occurs natural water as arsenate arsenite. Additionally, arsenic may occur from industrial discharges or insecticide application. World Health Organization (WHO) Pakistan Standard Quality Control Authority have recommended permissible limit of 10 ppb for drinking water. at lower concentrations can be determined by using high tech instruments like the...
High levels of mycotoxin contamination have been reported in various food commodities Pakistan, however, there has no exposure assessment study using multiple mycotoxins' biomarkers. This aimed to simultaneously assess the five major mycotoxins: aflatoxin B
Recent studies on the removal of pollutants via adsorption include use carbon-based adsorbents, due to their high porosity and large surface area; however, such materials lack photoactive properties. This study evaluates synergistic effect integrated mesoporous carbon xerogel (derived from resorcinol formaldehyde) titanium dioxide (TiO2) for combined photodegradation application. The complex formed between TiO2 phase was investigated through FTIR, proving presence a Ti-O-C chemical linkage....
Water quality monitoring activities have recognized the nitrate contamination in drinking water sources as one of major issue Pakistan. Adopting a uniform sampling design, 747 samples were collected from a wide range irrigated or non-irrigated regions having distribution sixteen cities Lahore (79), Kasur (46), Faisalabad (30), Khushab (50), Chakwal (51), Mianwali Jhelum (53), Bahawalpur (60), Karachi Mirpur Khas (55), Peshawar (38), Risalpur (35), Quetta (81), Ziarat (21), Loralai Mastung...
There are limited data on exposure to mycotoxins in Pakistan. Here, we measured deoxynivalenol (DON), a common contaminant of wheat, and aflatoxin B1 (AFB1), known rice, using biomarkers exposure. Wheat (n = 195) rice 62) samples were analyzed for AFB1 DON levels, the corresponding urinary urine from rural population 264, aged 4–80 years, male 58%) ultra-sensitive liquid chromatography–tandem mass spectrometry. was detected 66% (5.04 ± 11.94 µg/kg) 3% wheat samples. AFM1 (hydroxylated form...
People's well-being and their economic development are linked to the availability accessibility of water. The Pind Dadan Khan tehsil located on right bank River Jhelum is a classic example water stressed confronting quality quantity issues. To evaluate usable potential qualitative variations groundwater, an integrated approach involving geophysical, risk assessment techniques was used. Accordingly, groundwater zones were categorized. A small shallow fresh pocket with acceptable (<1.5 dS/m)...
Abstract. To explore the possibility of fluoride toxicity, seven hundred and forty (747) water samples were collected from surface ground sources sixteen major cities Pakistan, adopting a uniform sampling design with distribution as: Lahore (79), Kasur (46), Faisalabad (30), Khushab (50), Chakwal (51), Mianwali Jhelum (53), Bahawalpur (60), Karachi Mirpur Khas (55), Peshawar (38), Risalpur (35), Quetta (81), Ziarat (21), Loralai Mastung (37). The comparison analytical findings WHO Guidelines...
The present study aimed to explore a new source of montmorillonite and develop an extraction purification protocol for its isolation from raw clay samples acquired the Koh-e-Suleiman mountain range in Pakistan. process involved collection source, identification quantification montmorillonite. Granulometric protocols increased content 21.8-25.1% 90.1-93.9% after small-scale 85.33-89.33% on larger scale. A techno-economic analysis highlighted practicality economic benefits large-scale...
Water contaminated with highly hazardous metals including arsenic (As) is one of the major challenges faced by mankind in present day. To address this pressing issue, hybrid beads were synthesized various concentrations zero valent iron oxide nanoparticles, i.e., 20% (FeCh-20), 40% (FeCh-40) and 60% (FeCh-60) impregnated into a polymer chitosan. These employed as an adsorbent under optimized conditions pH time to facilitate efficient removal adsorption cum reduction processes. X-ray...
