Abstract Quantitative analysis of materials from Heavy Ion PIXE spectra remains impeded by the lack reliable X-ray production cross section (XPCS) data. Although efforts at experimental induced XPCS measurements still continue, Multiple Ionisation (MI) effects, which are not fully described theory, render simulations data unreliable for large Z 1 /Z 2 collisions, especially low energies. This is also exacerbated random selection projectile-target combinations measured and reported available to validate theory. study explored heavy ion deviations those protons same velocity. enabled evaluations degree sections enhanced through MI with aim predicting due impact. The evaluation was carried out scaling theoretical proton ratios (R), were then used interpolation in´missing´in´missing´ regions. Here we present total L-shell in Bi, determine HI/p C, F, Cl Ti projectiles an velocity range 0.2-1.0 (MeV/nucleon).

Groundwater contamination by nitrate and heavy metals is a growing global concern due to its detrimental effects on human health through ingestion dermal exposure. This study aimed assess the concentrations of (Pb, Cu, Cd, Fe) in groundwater evaluate associated risks among different age groups (females, males, children) Nnewi Awka regions southeast Nigeria. Standard methods were followed. Ten samples collected from each locality, their physicochemical parameters analyzed. The evaluation metal levels was conducted using cancer hazard index as indicators public impact. results showed that while within acceptable limits, exceeded permissible all samples. Carcinogenic risk (CR) analysis revealed approximately 40% 80% permitted range ≤1 × 10 −6–1 −4. In region, order toxicity Cd > Pb Cu Fe, Awka, it resulting severe non-carcinogenic hazards for users. identified most significant contaminants impacting water quality both regions. Children exhibited greater vulnerability compared adults areas. These findings contribute our understanding localized contamination, highlight children, emphasize importance regular monitoring management practices.

Abstract The groundwater quality of the Gopalganj district in Bangladesh was not well documented. Therefore, this research done to determine study area. water index and human health risk for heavy metal ingestion were used describe quality. performed through estimation turbidity, pH, electrical conductivity, total dissolved solids, concentration sodium, potassium, ammonium, nitrate, iron, manganese, zinc, copper, arsenic. mean solids two upazila within permissible limit. However, conductivity both higher than WHO-prescribed value which Kotalipara. Excess concentrations iron arsenic found Kashiani upazila, but these below detection limit Kotalipara upazila. revealed that roughly 61.0% samples poor about 96.0% excellent Chronic risks due revelation drinking have also been determined by assessing hazard quotient index.

The composition of groundwater governs the drinking and irrigation water suitability. A large part coastal region Bangladesh is affected responsible for changing groundwater. This research attempted to observe quality Bhola Sadar Char Fasson upazilas in Bangladesh. Twenty-eight (28) samples, 27 at depths 260–430 m (850–1400 ft) 1 from a crop field, were collected analyzed. samples was determined through evaluation odor, color, turbidity, electrical conductivity, pH, total dissolved solids, nitrate (NO3−), ammonium (NH4+), sodium (Na), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), manganese (Mn), copper (Cu), zinc (Zn) arsenic (As) ions. An Atomic Absorption Spectrophotometer used heavy metal analysis. outcomes compared with World Health Organization. results showed that average values nearly all parameters underneath or within standard level, representing appropriate purposes. also Food Agriculture It found suitable irrigation.

Quantification of the non-linear relationship between arsenic (As) and physico-chemical parameters in groundwater through a Self-Organizing Map (SOM) was performed for first time Chapai-Nawabganj, Bangladesh. Due to continuous assessment quality, spatial distribution As with associated elements observed aerial extent contaminated groundwater. The results exhibited that 57 % 31 samples (n = 35) exceeded allowable limit according WHO recommended drinking water standard (10 μg/L) Bangladesh Drinking Water Standard (BDWS) (50 μg/L), respectively. map demonstrated higher concentration found central portion study area less amount eastern part. Whereas 83 iron (Fe) surpassed guideline (0.3 mg/L) were distributed all over except Moreover, manganese (Mn) varied from place within WHO.
