“…Leachate, which is produced by leaching and degradation of municipal solid waste deposited in landfills and contains a variety of pollutants in high concentration [ 5 , 6 , 7 ], is an important potential groundwater pollution source [ 8 , 9 ]. Heavy metals [ 10 , 11 ] and organic pollutants [ 12 , 13 ] in leachate can migrate for long distances in groundwater and accumulate in every link of the food chain, resulting in decreased cell activity, disturbance of human and animal endocrine systems, and even a variety of adverse health effects [ 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. To eliminate or avoid the substantial risk to local groundwater resource user and the natural environment, and achieve effective management of drinking water source safety, it is essential to identify groundwater pollution around landfills and assess the corresponding health risks.…”

The shallow weathering fissure groundwater in the red-bed area of Southwest China is usually the only drinking water source for most rural residents. In this study, a typical landfill with surrounding residents drinking unpurified groundwater in red-bed area was selected and water quality detection, groundwater numerical simulation and human health risk assessment were used to identify and assess groundwater pollution in the region. The chemical type evolved from HCO3-SO4-Ca-Mg and HCO3-SO4-Ca to Na-Ca-Cl-HCO3 contaminated by the landfill. Na+ and Cl− were selected as factors for rapid identification of groundwater pollution. Subsequent analyses using these factors showed that the leachate pollution plume boundary was 190 m downstream of the landfill. Analysis of the redox conditions revealed that the area from the landfill to 5 m downstream was the reduction zone, while the area beyond 5 m was the oxidation zone. The migration and attenuation patterns of inorganic salts (such as SO42−) and heavy metals (such as Fe and Mn) in the oxidation and reduction zones differed obviously. Meanwhile, the organic pollutants in the leachate were reduced and decomposed into organic acids, which caused the groundwater 80 m downstream of the landfill to become weakly acidic (pH ranged from 6.51 to 6.83), and promoted re-entry of adsorbed heavy metals (such as Pb) into the groundwater. The groundwater risk assessment based on human health revealed that lead, manganese, chlorobenzene, dichloroethane and chloroform constituted a major health threat to the residents. The rank of non-carcinogenic risk was lead >manganese, and the maximum area of non-carcinogenic risk was 15,485 m2. The total carcinogenic risk caused by organic pollutants was 7.9 × 10−6, and the area of the carcinogenic risk zone was 11,414 m2. Overall, the results of this study provide a scientific basis for management of drinking water and groundwater remediation in the red-bed area with low permeability.

“…The above 30 adhesive samples showed wide difference in chemical compositions and concentrations. To further compare the health risk potentials caused by the compounds released from these adhesives, inhaled cancer and noncancer risks were calculated according to the methodology recommended by the United States Environmental Protection Agency (USEPA) [ 48 , 49 ]. The exposure concentration (EC) was estimated to calculate the inhalation exposure to volatile compounds emitted from adhesives.…”

Characterizing Key Volatile Pollutants Emitted from Adhesives by Chemical Compositions, Odor Contributions and Health Risks

As one of the major sources of volatile pollutants in indoor air, gaseous emissions from adhesives during interior decoration have attracted increasing concern. Identifying major volatile pollutants and the risk in adhesive gaseous emissions is of great significance, but remains rarely reported. In the present research, we assessed the major volatile pollutants emitted from white emulsion adhesive and silicone adhesive samples (n = 30) from three aspects: chemical composition, odor and health risk contributions. The results showed that a total of 21 volatile pollutants were detected. Significantly, xylene was the most concentrated compound from white emulsion adhesives, accounting for 45.51% of the total concentrations. Butanone oxime was the most concentrated compound in silicone adhesives, accounting for 69.86% of the total concentrations. The trends in odor concentration (evaluated by the odor activity value method) over time were well correlated with the total chemical concentrations. Xylene (58.00%) and butanone oxime (76.75%) showed the highest odor contribution, respectively. Moreover, from an integrated perspective of chemical emissions, odor and health risk contributions, xylene, ethylbenzene, ethyl acetate and benzene were identified as the key volatile pollutants emitted from the white emulsion adhesives, while butanone oxime, butanone, and ethanol were the key volatile pollutants emitted from the silicone adhesives. This study not only identified the key volatile pollutants but also provided characteristics of odor and health risks of gas emitted from adhesives.

“…In recent years, many newly-identified sources have been reported, including emissions from oil and natural gas extraction industry [ 24 ], pyrolysis of waste plastics [ 25 ], pulp and paper industry [ 26 ], domestic waste landfill sites [ 27 ], household laser processing machines [ 28 ], and emissions from operations during electrosurgery [ 29 – 32 ], and from plants [ 33 ] and a soil bacterium species [ 34 ]. Among them, two types of sources are worth special attention.…”

“…The concentrations of BD in small cities and rural areas are usually lower, as a result, the cancer risks are lower (approximately 10 -6 ) [ 74 , 75 ]. On the other hand, the cancer risks at industrial sites or in areas with industrial point sources of BD are usually high [ 76 ]; the risks at heavily-polluted sites or those caused by occupational exposure can even reach 10 -3 [ 27 , 53 , 77 ]. Due to its high inhalation unit cancer risk, BD is often a major contributor to the total cancer risks caused by VOCs in industrial sites.…”

Abstract1,3-Butadiene (BD) is a petrochemical manufactured in high volumes. It is a human carcinogen and can induce lymphohematopoietic cancers, particularly leukemia, in occupationally-exposed workers. BD is an air pollutant with the major environmental sources being automobile exhaust and tobacco smoke. It is one of the major constituents and is considered the most carcinogenic compound in cigarette smoke. The BD concentrations in urban areas usually vary between 0.01 and 3.3 μg/m3 but can be significantly higher in some microenvironments. For BD exposure of the general population, microenvironments, particularly indoor microenvironments, are the primary determinant and environmental tobacco smoke is the main contributor. BD has high cancer risk and has been ranked the second or the third in the environmental pollutants monitored in most urban areas, with the cancer risks exceeding 10-5. Mutagenicity/carcinogenicity of BD is mediated by its genotoxic metabolites but the specific metabolite(s) responsible for the effects in humans have not been determined. BD can be bioactivated to yield three mutagenic epoxide metabolites by cytochrome P450 enzymes, or potentially be biotransformed into a mutagenic chlorohydrin by myeloperoxidase, a peroxidase almost specifically present in neutrophils and monocytes. Several urinary BD biomarkers have been developed, among which N-acetyl-S-(4-hydroxy-2-buten-1-yl)-L-cysteine is the most sensitive and is suitable for biomonitoring BD exposure in the general population. Exposure to BD has been associated with leukemia, cardiovascular disease, and possibly reproductive effects, and may be associated with several cancers, autism, and asthma in children. Collectively, BD is a ubiquitous pollutant that has been associated with a range of adverse health effects and diseases with children being a subpopulation with potentially greater susceptibility. Its adverse effects on human health may have been underestimated and more studies are needed.
