“…4. The average HQ value for the adults for all the heavy metals is well under the safe limit, which means there is no non-carcinogenic unfavorable impact on adults [34]. The HQs value decreased in the order of Zn < Ni < Cu < Cr < Pb in mosquito coils and Ni < Zn < Cu < Cr < Pb in cigarette samples.…”

“…The data on the carcinogenic types and the inhalation unit risk of the metals are acquired from the USEPA database for integrated information risk system (IRIS). The reference values of carcinogenic risk by dermal exposure and ingestion were not provided by the USEPA, so in our study, we have examined the only carcinogenic risk of metals via inhalation pathway [34]. If the value of risk drops between the ranges (10 −6 -10 −4 ), then the contamination likely does not produce carcinogenic risk [38].…”

The objectives of this study were to characterize the emissions of indoor air pollutants from the burning of mosquito coils and cigarettes using a closed environmental chamber, to compare air pollutant emissions from different types of mosquito coils and cigarettes, which are popular in Indian market; to quantify emissions from burning of mosquito coils and cigarettes with respect to particulate matter (PM 0.25 , PM 1.0 , PM 2.5 , and PM 10) and metals. Smoke contains several thousands of chemicals and heavy metals, and most of them are formed during the burning of cigarettes and burning of mosquito coils. The present study attempts to characterize the emissions of PM and heavy metals from different types of mosquito coils and cigarettes burning which were monitored in three different phases pre-burning, during burning, and post-burning. Five different brands of cigarette and mosquito coils were taken which are commonly used in India. Samples collected were analyzed for heavy metal (Al, Cu, Zn, Cd, Cr, Mn, Ni, Pb, V, Se, and Sc) concentration using ICP-AES, and the morphological analysis was performed with the help of scanning electron microscopy. The trend of concentration of PM in mosquito coil is followed as M1 > M3 > M2 > M4 > M5, and in a cigarette it was C5 > C2 > C4 > C3 > C1. The study suggests that burning of mosquito coil and a cigarette in the indoor environment emits quiet higher respirable PM, which may on prolonged exposure lead to illnesses. The maximum concentration of Al, Cu, Zn and Mn was found higher, while that of Cd, V and Se was below the detection limit in both types of samples. Calculations were made to explore expected cancer and non-cancer risks, using published toxicity potentials for three metals (Cr, Pb, and Ni). Hazards quotient values for adults were under safe limit. The order of excess cancer risk for the carcinogenic elements follows the similar trend for both cigarette and mosquito coils in adults; it was observed as Pb < Ni < Cr. Overall, the cancer risk was below the acceptable level (10 −4-10 −6).

“…Nickel also has been classified as group A materials, known human carcinogens. From the research findings it is evident that Ni was mainly emitted from tobacco or cigarette smoke and outdoor sources like the industrial or refinery emissions can contribute to it in an indoor environment [29]. Lead on the other hand is also a probable human carcinogen (group B2), but human evidence is inadequate and its unit risk is currently being amended by the US EPA.…”

Adverse health effects from exposure to air pollution are a global challenge and of widespread concern. Therefore, the present study attempted to pave the way in the study of indoor air pollution by coarse and fine particulate matter and picturesque its relation with the different indoor microenvironment. A campaign study was conducted in the city of Taj "Agra," India in which different microenvironments were selected (i.e., offices, shops, and commercial centers). For each site, two different locations were chosen to examine the coarse particles (PM 10 and PM 5.0)andfine particles (PM 2.5 ,PM 1.0 ,PM 0.5 and PM 0.25) concentrations and metal concentration of Zn, Pb, Ni, Fe, Cr, Cd, Mg and Cu in PM 2.5 and for their related health effects. The exposure factor and health risk assessment for carcinogenic effects due to heavy metal contaminants have also been calculated for adults working in different microenvironment by following the methodology prescribed by US EPA.

Jharia Coalfield (JCF) has been affected by coalmine fire and subsidence problems for several years. The emission of particulate pollutants is due to the history of unscientific and unregulated coal mining in the JCF area. In the present study (conducted in the year 2019), seasonal variations, possible causes, and human health hazards of particulate matter (PM10)‐bound trace metals like Cd, Cu, Fe, Cr, Ni, Mn, Co, Pb, Zn, and As were estimated. The mean concentration of PM10 (418 ± 67 µg/m3) exceeded the limit of NAAQS (National Ambient Air Quality Standards India, 2009) by a factor of 4.18. PM10‐bound trace metal concentrations were found in the order of Fe > Mn > Cu > Zn > Cr > Pb > Co > Ni > Cd > As. The maximum trace metal concentrations of all the metals studied were observed at the mining areas of JCF affected by coalmine fire. Human health carcinogenic and noncarcinogenic risks in children and adults were estimated through exposure pathways, ingestion, dermal contact, and inhalation. The cancer risk was evaluated as excess cancer risk (ECR). Noncancer risk estimates were evaluated as the hazard index (HI) and the hazard quotient (HQ). The HI and HQ values for Cr, Cu, Cd, As, and Pb at coalmine‐fire‐affected areas were observed to be higher than the value of safe dose (≤1), showing a possible noncarcinogenic risk to the inhabitants as a result of multielemental toxicity. The ECR values (>10−6) in JCF areas suggested a carcinogenic risk to the populace of the area, owing to inhalation of PM10‐linked Cd. Active mine fire (related to mining activities), higher transportation load, and resuspended particulate matter from road transportation were identified as the possible causes of the estimated risks based on principal component analysis and Pearson correlation analyses.
