“…Animal studies also suggest there may be potential for wildfire smoke to induce epigenetic change in humans. Research conducted by Vokina et al (2019) found that the exposure of rats to wildfire smoke for 7 days resulted in greater DNA methylation in cells of the testes, and revealed transgenerational effects manifesting as persistent changes in offspring behaviour. However, there is no direct evidence of transgenerational effects in humans.…”

The Anthropocene Review

The Anthropocene literature has brought attention to the plasticity and porosity of Earth systems under the dramatic impact of human activities. Moving across scales of analysis, this paper focuses attention on anthropogenic effects at the micro-scale of genomic regulation, neuronal functioning and cellular activity. Building on expanding dialogues at the interface of Anthropocene science, biogeography, microbiology and ecotoxicology, we mobilize epigenetic findings to show increasing evidence of anthropogenic changes in plants, animals and human bodies. Treating human-induced changes at the macro-global and micro-biological scales as part of an intertwined process has implications for how these problems are conceptualised and addressed. While we are sceptics about major geo-bio-social syntheses, we believe that agile social-scientific tools can facilitate interaction across disciplines without denying unevenness, and differences. If rightly contextualized in broad anthropological and social science frameworks, biosocial work on epigenetics offers a compelling avenue to make detectable the ‘slow violence’ of everyday pollution, racism, inequalities and the disproportionate impact of the Anthropocene on the poor and vulnerable. Consolidating work at the Anthropocene/biology interface has potential to offer a richer and more complete picture of the present crisis at the macro and micro-scale alike.

“…This smoke is composed of a mix of gases and airborne particulates, some of which pose risks to normal biological functioning ( Erb et al 2018 , Vokina et al 2019 , Sanderfoot et al 2021 ). The smoke emissions can affect the air quality locally or even far from the fires ( Einfeld et al 1991 , Ward et al 1992 , Streets et al 2003 , Chen et al 2017 , Cascio 2018 , Wang et al 2020 , Roberts and Wooster 2021 ).…”

Systematic Mapping and Review of Landscape Fire Smoke (LFS) Exposure Impacts on Insects

Landscape fire activity is changing in many regions because of climate change. Smoke emissions from landscape fires contain many harmful air pollutants, and beyond the potential hazard posed to human health, these also have ecological impacts. Insects play essential roles in most ecosystems worldwide, and some work suggests they may also be sensitive to smoke exposure. There is therefore a need for a comprehensive review of smoke impacts on insects. We systematically reviewed the scientific literature from 1930 to 2022 to synthesize the current state of knowledge of the impacts of smoke exposure from landscape fires on the development, behavior, and mortality of insects. We found: (1) 42 relevant studies that met our criteria, with 29% focused on the United States of America and 19% on Canada; (2) of these, 40 insect species were discussed, all of which were sensitive to smoke pollution; (3) most of the existing research focuses on how insect behavior responds to landscape fire smoke (LFS); (4) species react differently to smoke exposure, with for example some species being attracted to the smoke (e.g., some beetles) while others are repelled (e.g., some bees). This review consolidates the current state of knowledge on how smoke impacts insects and highlights areas that may need further investigation. This is particularly relevant since smoke impacts on insect communities will likely worsen in some areas due to increasing levels of biomass burning resulting from the joint pressures of climate change, land use change, and more intense land management involving fire.

“…It was revealed that chemotherapy applied in treating fathers for cancer modified sperm epigenome and entailed probable transgenerational transfer [19]. It was also established that when male and female rats were poisoned with combustion products prior to coupling, it led to changes in offspring's behavior and development [20]; when parents, either mothers or fathers or both, worked under adverse conditions, it was associated with an increase in primary morbidity, chronic pathology of the upper respiratory tracts, and frequent positive tests for allergens in children [21]. It was also shown that threats of miscarriage, gestosis in the first half of pregnancy, intrauterine hypoxia, and delayed fetus development in women employed at petroleum processing enterprises were to a great extent occupationally induced [10,21].…”

At present allergic diseases are detected in 30% people and their frequency is only growing. A significant role in allergic pathology occurrence belongs to ambient air contamination and chemicals being introduced not only into children’s bodies, but their parents’ ones as well since pollutants can act as allergens and sensitizing agents. Our research goal was to examine influence exerted by parents’ pre-gestation exposure to chemicals on sensitization among teenagers living in an area where ambient air was contaminated. We examined overall immunoglobulin E contents and leukocytes migration inhibition test with formaldehyde and sodium nitrite in 115 teenagers whose parents worked under adverse working conditions at chemical and petrochemical enterprises and in 244 schoolchildren whose parents didn’t have any occupational contacts with chemicals. Each group was divided into sub-groups depending on inhalation chemical burden on schoolchildren’s bodies caused by ambient air contamination and contaminated air indoors (with hazard index (HI) for immune disorders being lower than 2 and HI≥2). The research allowed establishing that teenagers whose parents had worked at chemical and petrochemical enterprises during a pre-gestation period had elevated IgE contents more frequently as well as changes in leukocytes migration inhibition test with formaldehyde; it indicated there was sensitization to this chemical. Parents’ occupational contacts with chemicals led to an increase in relative risks of elevated igE contents and 2.5 times higher sensitization among schoolchildren with HI<2. Risk that sensitization to formaldehyde might occur was equal to 2.3 among senior schoolchildren with HI≥2 whose parents worked at chemical enterprises.
