“…This paper uses a health risk assessment model recommended by the U.S. Environmental Protection Agency (USEPA) to evaluate the groundwater quality in the oil shale mining areas [28][29][30][31]. There are many ways for pollutants in water to enter the human body [32,33], and many studies have confirmed that direct consumption is the most harmful to human health [34][35][36][37]. Therefore, this study only considers direct consumption and ignores the other pathways.…”

To clarify the risk posed to groundwater in oil shale in situ mining areas, we examine five leached pollutants: Fe, Mn, Cr, sulfate, and ammonia nitrogen. Potential groundwater contents of these five pollutants were evaluated using an improved Nemero comprehensive index method and a health risk assessment method. The results show that, compared with the Class III groundwater quality standard (GB/T 14848-2017) used in the People’s Republic of China, average values of Fe, Mn, and sulfate in leaching solution from Fuyu oil shale exceed the standard, while Cr and ammonia nitrogen do not exceed the standard, and the leaching solution is within Class V groundwater quality. The average values of Fe and Mn in the leaching solution from Fushun oil shale exceed the Class III standard, while Cr, sulfate, and ammonia nitrogen values from this oil shale do not exceed the standard, and the leaching solution is Class IV in terms of groundwater quality. The weighting value used in the Nemero assessment method for the heavy metal Cr is the largest as its potential to cause harm to groundwater quality is the largest. The weight value for sulfate is the smallest as the harm degree is the smallest. The chemical carcinogen Cr has the greatest potential impact on human health. The health risk caused by the chemical non-carcinogen Mn is greater than that caused by Fe and ammonia nitrogen. When high pyrolysis temperatures are used, Mn will be released into groundwater in large quantities. Therefore, supervision and control should be strengthened. The results presented here can provide a reference for the comprehensive evaluation of groundwater risks caused by in situ oil shale mining.

Fluoride is known to play a significant role in dental formation. High fluoride intake leads to different symptoms one of them is dental fluorosis, which is chronic dental toxicity. Various indexes have been introduced to measure the intensity and severity of dental fluorosis. Some of these indexes are fluoride specific, such as Dean’s index, Thylstrup and Fejerskov index, the Tooth Surface Index of Fluorosis index, ICMR index. While others are non-fluoride descriptive indexes such as the Developmental Defects of enamel index. Dental fluorosis is most commonly assessed by clinical examination by experts in these indexes, but nowadays, technical assistance such as photographs is used for diagnosis. Recent advancements have also witnessed the development of Visual analog scales and quantitative light fluorescence methods for dental fluorosis assessments. This review article focuses on important techniques and indexes used in the evaluation and characterization of dental fluorosis. A comparative review analysis of available indexes and the scope of future advancements have also been compiled.

Arsenic is considered one of the most hazardous trace metals in groundwater researched to date because of the hazardous impacts like cancer, skin irritation, and other skin‐related diseases. The present study involved collecting 60 water samples from Bhagalpur district, Bihar, India, to estimate the arsenic concentration. The human health risk assessment of the samples concerning children and adults was also performed, and the maximum concentration of arsenic was found to be relatively high in some sample sites. Prolonged exposure to arsenic could be fatal to the local population. The current study also focuses on developing a low‐cost paper‐based arsenic detection kit. The paper‐based test kit was tested for parameters like color development for different forms and concentrations of arsenic, storage conditions for the test strips, the effect of different interfering agents on color development, and optimization of the AgNO3 solution. The cost analysis was carried out, and it was found that the kit would cost 0.046 USD per sample, which is 70–100 times lower than the cost of current methods.
